Strict requirements for the non-standard flange materials

Non-standard flanges refers to metallic materials with a refractoriness of not less than 1587 °C. It should be adopted according to the product design requirements and should comply with the current relevant national material standards. The non-standard flange is subjected to various physical and mechanical movements in the high temperature environment, so that the refractory material may be damaged by melting, softening, cracking and abrasion.

Non-standard Flanges

The non-standard flange materials mainly have the following strict requirements:

(1) Stainless steel and fuses have high temperatures and do not change and melt at operating temperatures;

(2) It can withstand the stress generated during high temperature operation, without losing structural strength, without deformation or breaking;

(3) The volume is stable at high temperatures, and the masonry is not deformed or cracked due to expansion and contraction;

(4) Non-standard flanges shall not rupture and peel off when the temperature changes or the heat is uneven;

(5) It should have a certain ability to resist chemical attack;

(6) It should have sufficient strength and wear resistance to withstand the scouring and impact of high temperature and high speed flame, soot and slag;
