Metal hose construction!

Net sleeve is the hose installed in the pressure pipeline of the main pressure parts, and the corrugated pipe sheath, according to the size of the pipe pressure and the application place, can choose a layer or multiple layers of stainless steel wire or steel belt for weaving, shuguang brand hose pressure range is generally PN0.6-32.0 Mpa. Up to 42.0MPa. Due to the production of the main parts of the hose material is made of austenitic stainless steel, thus ensuring the hose excellent temperature resistance and corrosion resistance, the hose working temperature range is very wide, -196-600 degrees, the use of the hose according to the corrosion of the medium through the pipe to choose the appropriate stainless steel brand, can ensure the corrosion resistance of the hose. Scope of application: conveying pipe that needs sufficient flexibility to prevent vibration, suitable for steam, gas, air, heavy oil, petroleum, chemical drugs and so on.

About metal hoses!

Metal Hose (English name: Metal Hose) one of the corrugated pipe series products. Metal hose is an important connection component in engineering technology, which is composed of corrugated flexible pipe, net sleeve and joint. In a variety of gas transmission, infusion pipeline system and length, temperature, position and Angle compensation system as compensation components, sealing components, connection components and shock absorption components, applied in aerospace, petrochemical, mine electronics, mechanical shipbuilding, medical and health, light textile electronics, energy and other fields. China has issued the national standard "Corrugated Metal Hose general Technical Conditions" (GB/T14525-93) in 1993. The metal hose is made of austenitic stainless steel or according to the user's requirements. It has excellent softness, corrosion resistance, high temperature resistance (-235℃ ~ +450℃), high pressure resistance (up to 32MPa). It can be connected in any direction in the pipeline. For temperature compensation and absorption of vibration, reduce noise, change the direction of medium transmission, eliminate the mechanical displacement between pipes or between pipes and equipment, double flange metal corrugated hose for displacement, vibration of all kinds of pumps, valves and other flexible joints are especially suitable.

Causes of hose rust

A metal reacts with oxygen in the atmosphere to form an oxide film on its surface. Iron oxide formed on ordinary carbon steel continues to be oxidized, causing corrosion to expand and eventually to form holes. Carbon steel can be secured by electroplating with paint or oxidation resistant metals such as zinc, nickel and chromium, but, as is known, this protection is only a thin film. If the protective coating is broken, the steel below begins to rust. The corrosion resistance of stainless steel hoses depends on the content of chromium. When the amount of chromium is added to 10.5%, the resistance to atmospheric corrosion of steel increases significantly, but at higher chromium content, although corrosion resistance is still improved, it is not significant. The reason is that alloying steel with chromium changes the type of surface oxide to resemble that formed on pure chromium metal. This closely adhered chromium-rich oxide protects the surface from further oxidation. This oxide layer is extremely thin, through which the natural luster of the stainless steel surface can be seen, giving stainless steel its unique surface. Moreover, if the surface is damaged, the exposed steel surface reacts with the atmosphere and repairs itself, reforming this "passivation film" that continues to protect. JR2 rectangular metal hose, this product uses all metal structure. Suitable for all kinds of metal chip and cutting machine tools. Prevent the damage of high hot iron filings to your power supply, water and steam lines, and protect labor safety.
