Why are 304L stainless steel flange expansion joints popular on the market

　　1、 When the medium is highly corrosive. 304L Stainless steel flange expansion joint refers to the pipe fitting with stainless steel flange expansion joint (flange or adapter). It can be cast. The stainless steel flange expansion joint is mainly a part that connects pipes with each other. First close the whole pipeline system, excavate and replace the damaged stainless steel flange expansion joint. This is not only laborious, but also affects the operation of the pipeline. Therefore, after the stainless steel flange expansion joint is buried, the first thing to do is to prevent corrosion.

　　2、 Before embedding, there shall be strict requirements for the planned trench. The groove shall be planned into a slope shape to prevent ponding at the expansion joint device of 304L stainless steel flange. Secondly, the stainless steel flange expansion joint shall be coated with anti-corrosion coating before installation.

　　If possible, asphalt cotton cloth can be used to reduce the contact with air and moisture after the stainless steel flange expansion joint is buried and ensure its stability. Stainless steel flange expansion joint in order to consider the locking of temperature change, it is usually opened to the top, and then return 1 / 2-1 turn as the position of all stainless steel flange expansion joint.

　　3、 Stainless steel flange expansion joint structure, medium and large diameter rolling bearings, easy to open and close. Because the data of the main components of the stainless steel flange expansion joint are austenitic stainless steel, the temperature resistance and corrosion resistance of the stainless steel flange expansion joint are guaranteed.

　　4、 The 304L stainless steel flange expansion joint shows coarse grain on the low magnification after overheating. Most stainless steel flange expansion joints have precipitates along the original high-temperature austenite grain boundary after overheating, and often show stable overheating.
