Alloy bending pipes are used in different places. For example, alloy bending pipes made of manganese steel have excellent properties such as impact, extrusion and material wear, which are usually used in those pipes with severe wear and consumption, such as concrete pipeline and mud pipeline. The high manganese steel bending pipe is used in the pipeline with strong fluid flow and strong impact. Nickel steel alloy bend is usually used in normal temperature transportation pipelines with high concentration of oxidized acid (nitric acid, sulfuric acid), but severely corroded in the transportation pipelines with reduced acid (hydrochloric acid, dilute sulfuric acid, etc.), unless the concentration of hydrochloric acid is very low. Martensitic alloy bend under 650 ℃ high temperature strength, oxidation resistance and water vapor corrosion resistant ability, but poor weldability. Therefore, it is often used in high temperature steam pipeline, water gas pipeline.

Alloy bend material: carbon steel, alloy, stainless steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, ar, PVC, PPR, RFPP(reinforced polypropylene), etc.

Manufacturing method: pushing, pressing, forging, casting, etc.

Production standards: national, electrical, ship, chemical, water, American, German, Japanese and Russian standards.

Technical requirements for alloy bending:

1. Each end should have a straight pipe section, which should not be less than the outer diameter of the pipe. For induction heating pipes, the recommended length of the straight pipe should meet the relevant standards.

2. When bending the pipe, the pipe should not be in contact with corrosive medium or harmful substances.

3. The pipe should be bent according to the qualified bending process, and the pipe should not be bent beyond the evaluation scope.

4. Heating temperature and cooling recommended by thermal bending shall conform to relevant standards.
