Features soft metal joints
1. Corrosion resistance: metal body with soft joints 304 or 316L stainless steel molding, both ends of stainless steel or carbon steel fitting joints with good corrosion resistance. Securing sealing ability. 2. beautiful appearance: the appearance of soft metal joints Cheng Liang, permanent bright as new. 3. The high pressure: Consider the actual operating pressure metal soft joints, using a variety of factors such as environmental conditions and usage, all the parameters have been a careful calculation and trial and error, to ensure their safety at work under pressure. 4. shockproof, anti-dislocation: stainless steel corrugated hydraulic hose assembly has good flexibility and compensation displacement characteristics. 5. Construction is good: for thin-walled metal flexible hose fitting fittings, our main business of stainless steel metal hose, the overall weight, which greatly reduces the load of construction jobs and construction time.

Pressure test and pressure resistance metal hose introduction!
Core Tip: Chinese net hydraulic hose fittings metal hose is an important part of modern industry. Wire and cable protection tube metal hose used for wire, cable, automated instrumentation signals and civilian shower hose specifications from 3m
Metal hydraulic hose couplings is an important part of modern industry. Metal hose used for wire, cable, wire and cable protection tube and civilian shower hose automated instrumentation signal specifications from 3mm to 150mm. Small caliber metal hose (inner diameter 3mm-25mm) is mainly used for precision optical ruler of the sensing circuit protection, industrial sensor circuit protection.
Metal hose needs to be pressure test, pressure test, also known as strength test, performance test are safe. The test pressure of 1.5 times the nominal pressure, test pressure medium is pure water, the chloride ion content should not exceed 25ppm. When the pressure test, each product must be carried out. Using a manual or electric pump pressure test, pressure test typically 1.5 to 4 times the available pressure range test gauge, or equivalent efficacy stress testing equipment, the test, the specimen tube is placed flat, one end of the mounting strap There exhaust valve plug, the other end and test pump outlet pipe connected to the water into the tube, discharged into the air, the exhaust valve closed, and then slowly increase the pressure to the required test pressure, keeping the pressure 5min, check style situation, leaks. Corruption and other forms of abnormal failure occurs. Qualified requirements do not allow leaks or signs of damage, such as failure modes appear abnormal. Qualified requirements do not allow leakage or bad signs and other forms of abnormal failure occurs.
Pressure hose as a flexible metal tube attached to the pressure liquid delivery system, to compensate for mutual displacement pipe or machine, the device connecting terminal, to absorb vibration energy, can play a vibration, noise and other effects, have good flexibility, light weight, corrosion resistance, fatigue resistance, high temperature and many other little. The Company stainless steel metal hose (bellows) Division production of stainless steel metal hose, metal hose, stainless steel flexible joints, the use of imported SUS304 (0Cr18Ni9) SUS316 (0Cr17Ni12Mo2) and SUS316L (00Cr17Ni14Mo2) material. One stainless steel wire braided hose, fluid delivery metal bellows, stainless steel pump even damping hose, stainless steel fire hose, stainless steel bellows, metal hose gas machinery in full compliance with national industry standards. Products with good flexibility, corrosion resistance, fatigue resistance, high temperature, noise damping, sealing strong, long life and other advantages. Widely used in textile, chemical, printing and dyeing, petroleum, chemical, steel, gas, air conditioning, automotive, fire, urban water supply, construction, metallurgy and petrochemical.
Metal hose is extremely thin-walled seamless or welded stainless steel tube through the public high precision plastic processing forming. Because of the elastic properties of the bellows profile determines the hose has good flexibility and fatigue resistance, making it very easy to absorb deformation of cyclic loading various sports, especially the ability to compensate for the large amount of displacement in the piping system. Corrugated metal hose pipe in two forms: one is a ring of metal hose, metal hose spiral one is.Metal hose nominal diameter range of DN6-1000mm, length optional. Our company is a bellows, metal hose, non-metallic compensation, soft rubber joints, sleeve compensator, a professional manufacturer of waterproof casing, is a large manufacturing base and backbone enterprises of similar products. End of the tube flange and carbon copper and other accessories, including the use of low-carbon steel welding parts. You can also use the user's requirements and conditions of stainless steel and low-alloy structural steels.Rational design and pipeline segments, each segment is determined using bellows expansion joints in the form and quantity. Determine the working pressure rating to calculate the amount of compensation required for each segment of the pipeline, to determine the nominal amount of compensation for each bellows expansion joint bellows expansion joints selection model based on diameter, pressure rating and compensation amount.
