The material of the corrugated compensator should meet the conditions

(1) High elastic limit, tensile strength and fatigue strength to ensure the normal operation of the corrugated compensator.

(2) Good welding performance, satisfactory welding process requirements of the corrugated compensator in the manufacturing process.

(3) Good plasticity, easy to be processed by the corrugated compensator, and sufficient hardness and strength can be obtained by a subsequent treatment process (cold work hardening, heat treatment, etc.).

(4) Good corrosion resistance, satisfactory corrugated compensator working in different environments. Most manufacturers use austenitic stainless steel, such as material grades 0Cr18Ni9 (equivalent to 304), 00Cr19Ni10 (equivalent to 304L), 0Cr17NiMo2 (equivalent to 316), 00Cr17Ni4Mo2 (equivalent to 316L). In order to improve the corrosion resistance of the corrugated compensator, the materials for the heat pipe network corrugated compensator are mostly 316 or 316L. These two materials are used for the heat pipe network and should be excellent materials for performance and price comparison.

For the heat pipe network laid in the trench, when the pipeline where the compensator is located is low, the rainwater or accidental sewage will be soaked in the corrugated compensator, and materials with stronger corrosion resistance, such as iron-nickel alloy, high-nickel alloy, etc., should be considered. .

On the basis of the widespread application of industrial flooring, with the continuous improvement of people's living standards, it has been promoted and applied in family decoration. Epoxy industrial flooring has become one of the fastest growing industries in China, attracting the attention of everyone. It can be factory-produced like cement products, and the prospects are even more impressive!
