WE PRODUCE HYDRAULIC HOSE ACCORDING TO SAE100 AND EN 853 STANDARDS In past three years, we began to use more and more high speed brading machine to produce hydraulic hose. There are many advantages in producing hydraulic hoses, we like to explain as following . 1) The brading machine speed is 3 times faster than old ones and can be equaled with MAYER made in Germany. 2) The braiding angel is properly made between inner tube and steel wire . The braiding angle can reach designed standard 54.44" degree 3) The steel wire can be pulled above 10 KG , which can make much better structure to assure burst pressure. 4) The machine braid the steel wire by 3X3 knotting, so the steel wire braiding cover is more flexible. When you bend hydraulic hose, the hose also will be more flexible. 5) With improved quality and high speed production, we can save time to produce customers order of hydraulic hose.

The machine of higher technology device began work today, and can reduce 60% VOCs, so the local government welcome the machine and allow more time for us to increase productivity of hydraulic hose, rubber hose, and hydraulic fittings. higher technology device to protect environment Release time: 2021-07-21 With more deeply development of Chinese economy , more pollution factories make. We decide to take higher technology device to protect environment. This new machine will replace old treatment system , and reduce about half of wasted gas VOCs. The local government and people appreciate highly for our activities, as well as our empolyees. During production of hydraulic hose, rubber hose, there are waste gas VOCs ,which brings air pollution . In past we use Carbon Black and UV Rays Oxidation to treat VOCs, it is qualitifed accoring to government requirement. Meanwhile it will make more Ozone , which produce more pollution. When we use higher technology of catalytic combustion after Carbon Black, there is no second time pollution. So, it is protection from that meaning. High quality hydraulic hose, rubber hose, and less pollution is in accordance with our development idea.

QUALITY CONTROL FOR HYDRAULIC HOSES (ONE) IN LABORATORY, BEFORE PRODUCTION 1) After finishing rubber sheet, in our laboratory, we test the hardness, according to our requirement in Shore A 82-85, rubber tensile must be above 12 MPA, which is for inner tube of hydraulic hoses. Outside rubber will be 80 Shore A and 8 MPA in tensile. 2) After we buy Steel Wire in middle parts, in our laboratory, we test the tensile, according to our requirement in 2750-2950N.The tensile must be in our required tolerance, to assure the working pressure and burst pressure. 3) In our laboratory, we make vulcanization inner tube rubber and outer rubber with steel wire. To check how much adhensive pulling power between them, to assure adhension in rubber hoses. Also, we will imitate vulcanization of production to assure rubber vulcanization is under our control in 5 minutes , 10 minutes, half hour and one hour above. (TWO) IN WORKSHOP, DURING PRODUCTION 1) To prepare PP or steel mandril in previous day, and dry the mandrill to assure it separate well from inner rubber, but not hurt inner tube. The PP mandril OD is higher requirement hen SAE and EN standards to control exact proper diameters of hydraulic hoses. 2) We adjust steel joint machines every week. We test the steel wire length difference according the tolerance of XN(7N,8N,9N,10N,11N,12N) standard to assure same length before braiding machine. 3 In Germany technology braiding machines, we adjust spider tension 0.5kg higher then standard of 8KGS, to assure braiding cover more compact and in good shape , higher than standard. The finishing of hydraulic hoses are in very good shape. 4) We use advanced cold feeder extruder, controlled by PLC computer. Cold feeder extruder has more power to extrude rubber inner tube in good shape. 5) After finishing extruding inner tube,we require to make it recovery previous shape in normal temperature, at least 8 hours, we begin to put in colding machine in -30C for braiding machine. 6) In braiding and spiral machine, we require pitch and steel wire distance in our standard. To assure the steel wire angle in control. (THREE) ATFER PRODUCTION, BEFORE SHIPPMENT. 1) After finishing hoses, we test proof pressure in 1.8 times of working pressure on EACH HOSE for one minute checking any possible leak or defective point of rubber hoses , before shipping to our customers. 2) The burst pressure of hydraulic hoses must reach 4 times of working pressure. 3) The impulse testing must be above 200000 circles for braided hydraulic hoses, and 400000 circles for spiraled hydraulic hoses.

Soft Rubber Hose Due to its construction, hydraulic hoses can be divided into following categories: hoses with textile braid (one or two layers). hose with one or two layers of steel wire braid (one, two and three layers). hoses with spiral wire braid (four or six layers). Hydraulic hoses are manufactured in imperial sizes and standardised. The most popular standards defining requirements for hoses are as follows: American SAE, German DIN, International ISO and European EN. Application: Mainly used for conveying of oxygen and acetylene gases for welding and cutting equipment. Tube: NR & SBR synthetic rubber, black color. Reinforcement: High tensile synthetic yarn braided or spiraled. Cover: NR & NBR synthetic rubber, red and blue etc. Characteristics: Abrasion resistant, weather resistant and zone resistant. Its of pressure bearable, flexible, light in weight, anti-bending, less distortion and nice smooth surface. Standard length: 30m, 50m, 100m Temperature range: -20ºC to +60 ºC Apart from standardised hoses (according to above mentioned norms) our offer includes hoses with increased flexibility, higher working temperature, increased abrasion resistance of external layer or better chemical resistance. For a proper choice of hydraulic hose to a particular application below mentioned aspects has to be taken into account: working pressure and working conditions (static/dynamic), medium and ambient temperature. Hydraulic hoses designed for mining applications must fulfil additional requirements connected with explosives and fire conditions present in mines. Hydraulic hoses assembled with the use of fittings crimped on crimping machines. Rubber hydraulic hoses find their most common use among hydraulic systems, mainly for transporting oil-based liquids, but they can also be used for water systems. They are great at maintaining internal pressure due to their rubber and steel composition, so they`re commonly found in applications where you`re transferring power from generator to nozzle. These flexible rubber hoses maintain their strength by using a reinforcement layer made from high tensile steel wire. An outer layer of synthetic rubber makes the hose resistant to oils, abrasion and weather exposure. You can build your own replacement hoses by combining bulk hydraulic hoses and attachments with our braided hose crimp fittings. Rubber hydraulic hose is a common and important element in countless industrial and mobile machines. It serves as the plumbing that routes hydraulic fluid between tanks, pumps, valves, cylinders and other fluid-power components. Plus, hose is generally straightforward to route and install, and it absorbs vibration and dampens noise. Hose assemblies-hose with couplings attached to the ends-are relatively simple to make. And if specified properly and not overly abused, hose can work trouble-free for hundreds of thousands of pressure cycles. Hydraulic hoses consist of an inner tube, one or more layers of reinforcement, and an outer cover. Each constituent should be selected with the intended application in mind. Typical operating and performance parameters include the size, temperature, fluid type, pressure-holding capacity and environment, to name a few. The cover protects the reinforcement layer. One consideration when determining the cover material is resistance to attack from outside influences like chemicals, salt water, steam, UV radiation and ozone. Common cover materials include nitrile, neoprene and PVC, among others. bend-radiusWhen a hose rubs against adjacent structures or other hoses, friction and abrasion can be concerns. That`s because if the cover wears away and exposes the reinforcement to mechanical and chemical attack, the hose will often quickly fail. A number of manufacturers offer tough, abrasion-resistant covers to help prevent harm. The demand for ever-larger, off-road equipment was the impetus behind the development of spiral hydraulic hose. Today, it is well-suited for applications that see extremely high impulse pressures. As just one example, hydrostatic drives on large dozers and earth movers often rely on four and six-wire spiral hydraulic hoses.

Types of Industrial High Pressure Hydraulic Rubber Hose To hose industry insiders, the term `industrial hose` is a broad term encompassing everything that isn`t metal, Teflon, hydraulic, and composite hose. Others say it`s all hose except for hydraulic hose. For people outside of the hose industry, `industrial hose` seems to refer to any and every hose: a heavy-duty 4-wire hydraulic hose, a large-bore stainless hose; these could easily be referred to as an industrial hose from someone who doesn`t directly deal with hose for industry on a consistent basis.  Water Hose Industrial Water HoseThis may seem like a rather straightforward category of industrial hose. To an extent, it can be. Water hose is generally made from one of three materials: EPDM or SBR for suction and PVC for discharge. For the most part, EPDM is the most common tube for water hose, especially when the hose is being used as a transfer hose. If your application is suction, your hose will require a helical wire to prevent the hose from collapsing. Steam Hose Steam hose, to an extent, runs the gamut when it comes to construction: there`s EPDM, nitrile in instances where oil resistance is needed, and chlorobutyl in more premium varieties, like when you need a hose that is going to stand the test of time. Most of these will handle temperatures north of 406°F for saturated steam and 450°F for superheated steam, with pressures up to 250 psi. on average.  Due to the dangerous nature of steam at higher temperatures and pressures, this is one of the few hose applications where we see a safety factor of 10:1 vs the standard 4:1. Steam can be incredibly dangerous. Depending on the type, temperature, and saturation, steam isn`t always visible, so an increased safety factor is prudent. Chemical Hose Chemical hoses are rather consistent throughout various manufacturers, and you`re essentially dealing with hose tubes that are UHMW or XLPE. There of course are others like FEP, high-purity EPDM for acid, and Nylon tube paint hoses are often listed in the chemical section too, but they are a specific use, specialty hose. Once you`ve decided which tube option suits your specific application, you`ll need to cover your pressure and temperature requirements. Various chemicals will need a certain tube material to handle the temperature or high-pressure chemical applications; though, high pressure and chemicals aren`t generally associated. Considering the use for your hose, is it suction and discharge or transfer only, you may need to consider the necessity of a helical wire. So that`s about it for most chemical applications: choose UHMW or XLPE for the tube and then decide if a helical wire is necessary. When you break down chemical hose into the few necessary requirements, it is pretty straight forward.  Air & Multi-Purpose Hose At the high-pressure end of the spectrum, you`re going to find steel-braided, nitrile hose that will handle pressures up to 1,500 psi air. Keep in mind that this is extremely high for an air hose. These types of hoses will typically be seen at heavy construction sites, mines, quarries, and plants/mills. From there, we work our way into the `medium-duty` hoses. These hoses typically have nitrile tubes and covers for good oil resistance, fabric braid reinforcement and handle pressures between 400-600 psi. In the 200-300 psi range, we have air and multi-purpose hoses for shop air and water, which are offered with EPDM rubber with lesser oil resistance and lower cost, or nitrile and other oil resistant materials.  PVC Hose Industrial PVC HosePVC (polyvinyl chloride) hoses see an awful lot of uses. Applications such as potable water, beverage dispensing, chemical dispensing, multipurpose air, and water, and many, many more. PVC is in a category all its own that reaches into a lot of the categories discussed prior, so what we see is a category not defined by its use, but rather its material.  High pressure hose for applications and in knitted forms HEBEI STRONGFLEX GROUP is a leading company in manufacturing high pressure hoses and our products are sold very well both at home and abroad. High pressure hoses - the most important part of modern equipment, are widely used for all hydraulic systems, gas and water supply to deliver fluids under pressure (oils, fats, emulsions and others).
