Pulished on Mar. 16, 2020

Carbon Steel Pipe Fittings Factory shares with you.


1. Flexible between metal hose pitches.

2. The metal hose has good elasticity, without blocking and stiffness.

3. The metal hose is light in weight and has good caliber consistency.

4. The metal hose is soft, repeatable and flexible.

5. The metal hose has good corrosion resistance and high-temperature resistance.

6. The metal hose is the anti-rat bite, wear-resistant, and prevents the internal wires from being worn.

7. Metal hoses are resistant to bending, tensile properties, and strong lateral pressure resistance.

8. Metal hose is soft and smooth, easy to thread installation and positioning.

Pipe Fittings


(1) High elastic limit, tensile strength, and fatigue strength to ensure the normal operation of the bellows. (2) Good plasticity, which is convenient for processing and forming of the corrugated pipe, and can obtain sufficient hardness and strength through subsequent processing processes (cold work hardening, heat treatment, etc.). (3) Good corrosion resistance, meeting the requirements of bellows working in different environments. (4) Good welding performance, meeting the welding process requirements of the corrugated pipe in the manufacturing process. For a thermal pipe network laid in a trench, when the compensator is located on a low-lying pipeline, rainwater or accidental sewage will soak the corrugated pipe. Materials with stronger corrosion resistance, such as iron-nickel alloys and high-nickel alloys, should be considered. Due to the high price of such materials, when manufacturing bellows, you can consider adding a layer of corrosion-resistant alloy only on the surface in contact with the corrosive medium. Fatigue life design According to the failure type and cause analysis of the corrugated tube compensator, it can be seen that the planar stability, circumferential stability and corrosion resistance of the corrugated tube are related to its displacement, which is the fatigue life. Too low fatigue life will cause the stability and corrosion resistance of metal bellows to decrease.
