Product Introduction
JR type metal hoses are important components in modern industrial equipment connecting pipelines. Metal hoses are used as wire and cable protection tubes for wires, cables, automation instrument signals, and civilian shower hoses, with specifications ranging from 3mm to 150mm. Ultra small caliber stainless steel hoses (inner diameter 3mm-25mm) are mainly used for the protection of sensing lines in precision optical rulers and industrial sensor lines, with good flexibility, corrosion resistance, high temperature resistance, wear resistance, and tensile strength.
Product advantages
The entire metal hose is made of 1Cr18Ni9Ti stainless steel material, which has strong corrosion resistance. Small caliber metal hoses (inner diameter 3mm-25mm) are mainly used for the protection of sensing circuits in precision optical rulers and industrial sensor circuits. Metal hose products include oil suction hoses, steam hoses, sandblasting hoses, acid and alkali suction hoses, food hoses, oxygen blowing hoses, and various special-shaped hoses. Widely used in industries such as machinery, chemical, petroleum, metallurgy, and food.
2. The hose body is a thin-walled stainless steel tube formed by hydraulic pressure, which has strong flexibility, elasticity, bending and vibration resistance. The reinforced protection of the woven mesh sleeve makes it have higher pressure bearing capacity.
3. The connection at both ends of the hose can also be made into other connection methods besides thread and flange standards, which is convenient for connection and use.
4. This product is not only suitable for matching with rotary joints, but also widely used for flexible connections in the transportation of various fluid media.
Product Features
1. Flexible hoses with small bending radius between metal hose pitches.
2. Metal hoses have good elasticity, no blockage or stiffness.
3. Metal hoses are lightweight and have good consistency in diameter.
4. Metal hoses have good flexibility, repeated bending, and flexibility.
5. Metal hoses have good corrosion resistance and high temperature resistance.
6. Metal hoses are resistant to rodent bites and wear, preventing internal wires from being worn out.
7. Metal hoses have strong resistance to bending, tensile strength, and lateral pressure.
8. The metal hose is soft and smooth, easy to thread, install and position.
9. Metal hoses come with multiple hose connectors, making them easy to connect with instruments and equipment.
