1, hose connections, fire hose when put in water with interfaces shall protector mat layer of soft, then fastened with galvanized wire or hose clamps.
2, with the use of water. When using the fire hose, high pressure hose should be connected closer to a place away from the pump, filled with water after the water should prevent sudden twisting or bending, but should prevent water stop Interface collision damage.
3, with the laying of water. When laying hose, to avoid sharp objects and various oils folder, when upward vertical laying of water, when you want to take advantage of the water with a hook, the laying of water through roads, water should be fitted with a protective bridge, by rail , the water zone should track the following through, avoiding water wheels grind tape is bad and intermittent water supply.
4, to prevent freezing. Winter season, when the court to suspend the fire water, to prevent freezing water stop, slow-running pumps need to keep a small amount of water.
5, with clean water, with the water used to clean, to deliver water with foam must be careful to wash, protection layer. Bring water to remove grease, soap and warm water or washing, melting of frozen water zone, the first to use it, then wash dry, no dry water with no receivables volume storage.

Maintenance: The quality of fire hose, fire fighting directly affect results, use the process, we must strengthen the maintenance.

1, management, fire hose must be someone responsible for the management, to prevent undue damage, all of the water with both qualitative classification shall be numbered and put on record in order to grasp the use of hose.

2, storage, fire hose not long on the outdoor sun and rain, can not be placed near heat sources to prevent aging, prevent pollution and corrosive viscous material, storage place, there should be a suitable temperature and good ventilation hose should single roll, heel on the hose reel frame or flipping several times a year and exchange folded several times, lorry with water, should avoid friction, to be exchanged fold if necessary.

SAE J1402 Air Pressure Brake Hose

As we know, Most heavy-duty trucks use dual air brake systems for safety. and stopping A dual air brake system has two separate air brake systems, which use a single set of brake controls. Each system has its own air tanks, hoses, lines, etc. One system typically operates the regular brakes on the rear axle or axles. The other system operates the regular brakes on the front axle (and possibly one rear axle). Both systems supply air to the trailer (if there is one). The first system is named the “primary” system. The other is named the “secondary” system. .Before driving a vehicle with a dual air system, allow time for the air compressor to build up a minimum of 95-100 psi pressure in both the primary and secondary systems. Watch the primary and secondary air pressure gauges (or needles, if the system has two needles in one gauge). Pay attention to the low air pressure warning light and buzzer. The warning light and buzzer should shut off when air pressure in both systems rises to a value set by the manufacturer. This value must be greater than 60 psi.

The warning light and buzzer should come on before the air pressure drops below 60 psi in either system. If this happens while driving, you should stop right away and safely park the vehicle. If one air system is very low on pressure, either the front or the rear brakes will not be operating fully. This means it will take you longer to stop. Bring the vehicle to a safe stop, and have the air brakes system inspected and repaired

To some this, up the various brake components in an air brake system work together to create and maintain a supply of compressed air, direct and control the flow of that air and to transform air pressure energy into mechanical braking force.

Radiator Hoses -the Precautions in the repairing

                            Nov 25, 2015 • By Tina Zhai 

                                   

As we konw,a hose is a hose, right? Well, generally this is true, but not when it comes to your radiator. Most people assume any old black hose from the parts store will do. This is wrong and can lead to hugely expensive problems like engine replacements!

Heat is the biggest threat to your engine. There are plenty of other potential threats, but uncontrolled heat can melt the internal components of your engine in less than 15 minutes. Controlling heat is incredibly important. Keeping your oil topped off is one step. Keeping your cooling system in tip top shape is also incredibly important.

What is the weak spot of any coolant system? The answer is the radiator hoses. These rubber composite hoses are actually very hardy. Still, they are under a lot of strain. The top hose connecting to the radiator is the transport for searing hot water. The bottom hose is put under vacuum pressure by the pump circulating the coolant/water mixture. Frankly, it is a surprise these two hoses last as long as they do.

Being a good car owner, you’ll keep an eye on the coolant hoses. After a bit, you notice they are starting to show signs of wear – bulging, softness and discoloration. You decide to replace them and head down to the parts store to find replacements. This is where things can go wrong. If you are a manly man, you aren’t going to ask for any help. You’ll just size up the potential hoses and go with the version that looks to be the same size as your current hoses. You may have just taken years off the life of your engine or killed it outright. How so? How could hoses make such a difference? Let’s take a closer look.

The two hoses connecting your radiator to the engine block deal with two different conditions. As we mentioned above, the top hose is moving hot water while the bottom hose is moving cooler water, but under a vacuum. You need a different hose for each of these conditions. The bottom hose must be the type that has metal wiring built into it. Why? The rubber will breakdown under the continual vacuum. This will cause the hose to squeeze together and reduce the coolant flow. You engine will start to overheat. At a minimum, this will take years off the life of the engine. If the hose cuts off to much of the flow, the engine can burn up in as little as 15 minutes. Yikes!

The top hose deals with different issues. The heated coolant/water mix coming out of the engine is brutally hot. This is not a good place to have wires. Instead, you want a basic rubber composite hose that can bend. It will be able to take the heat, but will degrade much slower than a wire embedded hose.

Replacing radiator hoses is fairly simple. The only issue is really making sure you have the correct hoses for both the bottom and top of the coolant system.

Air Conditioning Hose

                       


The rapid development of the automotive industry to the automotive accessory products - Hose bring development opportunities, if calculated according to each car using 20m hose, 2005 only new automobile production demand for hose m in 100 million or more, plus maintenance Hose, the market potential is huge. As the car to the high-speed, high functionality and comfort, such as the direction of development, as well as combustion of fuel use electrical equipment or parts of the EFI device is fully used, the turbo; in addition, to protect the environment, car use unleaded gasoline, air conditioning with R134a refrigerant to replace R12, automotive engine compartment narrowing, such as elevated temperature gave the car with a hose put forward higher requirements, fuel resistant, high temperature, low permeability of refrigerant, and long lifetime become the mainstream automotive hoses. From inside the hose layer structure, oil, heat and low permeability of refrigerant hoses are increasingly using a resin and a layer of rubber or a resin and two layers of rubber and rubber layers of different materials, This structure has been in the form of fuel hoses, air conditioning hoses, turbocharger hose been verified. In addition, high-performance rubber are increasingly being used, such as fluorine rubber, butyl rubber, silicone rubber, epichlorohydrin rubber, hydrogenated nitrile rubber, chlorosulfonated polyethylene rubber, acrylic rubber, EPDM Wait.

 1. A fuel hose with the use of unleaded petrol in the car EFI devices, structure and materials of the fuel hose has undergone great changes, the development of the inner layer with a fluorine rubber, epichlorohydrin rubber, nitrile or acrylate rubber substitute rubber. To reduce fuel permeability and further improve heat resistance, mostly inner layer of composite structure in which a fluorine rubber and epichlorohydrin rubber or acrylate rubber composition by extrusion molding. Since the fluorine rubber is expensive, so the fluorine rubber layer is relatively thin (0.2-0.7mm). Reinforcing layer is made of fiberglass, polyester fiber or nylon fiber braided or twisted together. The outer layer using epichlorohydrin rubber, acrylic rubber or chlorosulfonated polyethylene rubber neoprene substituted

  2 .air conditioning hoses Air conditioning hoses are also rapidly developing automotive hose products, currently has full rubber, rubber - resin composites, full resin air conditioning hose. Because of the large new air conditioning refrigerant R134a applications, air conditioning hose structure and material changes. From other international and national standards, their structure has rubber / fabric / rubber, rubber / steel / rubber, (thermoplastics) TP / fabric / rubber, rubber -TP- rubber / fabric / rubber, TP- rubber / fabric / rubber, TP- rubber -TP- rubber / fabric / rubber. Currently the most used rubber - resin composite structure, namely the inner layer by a layer of resin and a layer of rubber, this structure is considered to be adapted to new automotive air conditioning refrigerant R134a best choice.


    3. radiator hose. Vehicle development to energy efficiency and low pollution of direction so that the radiator hose working environment has undergone great changes, such as the engine compartment of the temperature rise from the original 110-125 ℃ to 125-150 ℃, even up 175 ℃, the original sulfur cure systems usually radiator hose production is gradually being replaced by peroxide systems produced radiator hose. Shanghai Shang Xiang Automobile Hose Co., Ltd. uses high-grade EPDM radiator hose as a host material and choose special synthetic fiber knitted fabric reinforced structure, the country's first cold feed extrusion technology and non-core preform cover die naked vulcanization new technology, succeeded in producing breaking strength, ozone resistance, adhesion strength and other technical indicators have reached the international standard automotive radiator hose. Wherein the pulse performance by Volkswagen AG found more than 300,000 times, far more than the international standards prescribed ≥15 million times. At present, this radiator hose has been recognized by Shanghai Volkswagen, FAW-Volkswagen and other companies.

    4. brake hose brake hose on the car is very strict quality requirements, related to the vehicles and personal safety of the important parts. In addition to resistance to brake fluid brake hoses, but also must have good aging resistance and moisture permeability properties. Previously, car brake hose layer materials used mainly in styrene-butadiene rubber. Recently, due to the maintenance-free car appeared, enhance and high boiling brake fluid using brake fluid temperature of the working environment, EPDM or EPDM / butyl rubber, styrene-butadiene rubber substituted trend. The inner layer and the outer layer mostly Brake Hose EPDM material, the layer between two layers of woven reinforcing layer of natural rubber, reinforced layer polyester, polyvinyl alcohol or rayon fibers, within layer can use more pressure nylon outer layer can also be used chlorosulfonated polyethylene rubber. The rapid development of the brake hose. Only brake hose plant in Nanjing 7425 annual production capacity has reached 8 million / a, and has become the Jetta, Red Flag, Beverly, Alto, Iveco cars, light trucks exclusive accessory products, accounting for 50% of the domestic market of the brake hose the above.

  5. power steering hose power steering hose contact medium is mineral oil, requiring heat performance, strong joints. Foreign automotive power steering system latest trends is the use of high-pressure pump, and the pump's miniaturization and higher power of the required hose improved heat resistance and durability, the inner layer with good oil resistance, the outer layer wear resistance heat (150 ℃ above), weatherability. This hose inside and outside the conventional layer material nitrile rubber and neoprene, now hydrogenated nitrile rubber, chlorosulfonated polyethylene rubber, chlorinated polyethylene, acrylic rubber direction. Hydraulic steering hose new structure is hydrogenated nitrile rubber as the inside layer, nylon 66 as reinforcing layer, chlorosulfonated polyethylene rubber as an outer layer. Compared with conventional hose, this hose life at 140 ℃ conditions can be increased by more than 2 times. To improve the heat resistance, power steering hose also has fluorine rubber, but easy to play due to the fluorine rubber and oil additives in certain reaction, and thus the application subject to certain restrictions.

  6. turbocharger hose abroad, the current turbocharger hose structure all-rubber, fluorine rubber inner layer and the silicone rubber composition of good heat resistance, high strength reinforcing layer made of aramid fiber knit, the outer rubber layer is made of silicone rubber.

We should be in terms of product structure, production processes, new materials and other aspects, with the help of foreign advanced technology and equipment, to develop new products, improve the quality of automotive hoses.

Nylon Tubing in automotive applications

              Nylon Tubing in automotive applications

PU/PA Tube

                                    

Currently ,More and more Nylon Tubing is replaced and employed as fuel line against rubber hoses and metal pipe in automotive applications. Nylon tube has comparatively smoother and cleaner internal surface and its installation is quick and easy. It is capable of working at high temperature and pressure in trucks and cars. It is fully resistant to automotive fuels like petrol and diesel. All these qualities make Nylon Tube favorable for many OEMs.

Nylon-6, Nylon-12 and Nylon-11 are mainly preferred to manufacture Nylon Tubes. Some manufacturers also use Nylon6-10 and some even use Nylon 6-12. Few manufacturers have started using Nylon12-12 to make tubes to be used as fuel lines. Different applications require different types of Nylons. Nylon 12 and Nylon 11 are more flexible than other nylons. However, at the same time, tubes made from nylon12 and nylon11 have less pressure withstanding capability.

Nylon tube is widely used in industries for various applications. Apart from as fuel lines, nylon tubing is used for oil circulation in lubrication and hydraulic system. Similarly, it is the first choice in pneumatic system. It is equally common in automotive industryas fuel lines in particularly in cars, trucks and trailers.

Advantages of Nylon Tubing as automotive fuel line are many and some important are;

• It has excellent physical properties and it has high bursting pressure and so can withstand high working pressure.
• It can easily resist vibration that come during vehicle movement and this is because of having good flexibility.
• Surroundings of engine may experience elevated temperature but it is capable of withstanding high temperature.

Characteristics:

Excellent flexibility, bending radius is small.           

Non-toxic, smelless.

Hardness is constant, service life is long.

Applications:

Used for Industry robots and pneumatic tools. Tranport water and other liquid, it works at temprature from -40℃ to 90℃.

  

Car and trucks manufacturers- OEMs- in Europe and Japan prefer Nylon Tubing as a trusted source for their fuel lines and it has lately become the choice material for them.
