Stainless steel cold bolt corrosion resistance drop element, selects the vacuum hardening, vacuum safe treatment and measures for the inductive technology of stainless steel screw chemical passivation of parts processing, and pass by neutral salt spray test before and after treatment were investigated parts corrosion resistance change.

The results show that the above treatment technique is used to recover the corrosion resistance of the parts and ensure the reliability of the environment function of the stainless steel adapter. Stainless steel cold bolt corrosion resistance drop element, vacuum hardening, vacuum treatment and chemical passivation of technical measures for processing of parts, and pass by neutral salt spray test before and after treatment were investigated parts corrosion resistance change. The results show that the above treatment technique is used to recover the corrosion resistance of the parts and ensure the reliability of the stainless steel stainless steel u-bolt electric adapters. Bolt flange connecting system is the most commonly used connecting equipment in industrial pressure vessels and pipelines. The gasket in the connecting system is the main component that directly influences the sealing cohesion. The study on the size and distribution of the stress of the gasket on different loads and different scales is of great significance to the sealing function of the gasket and the avoidance of leakage. First, the general structure and type of gasket are introduced, and the main function request of gasket is discussed. No asbestos paper of self-denial surrounded by metal gasket deflation springback experiment curve fitting analysis, obtained can represent the class gasket springback function of austerity tightening curve equation, through calculation, the method gets the curve and the practice of similar degree is higher, can be a good characterization of tightening the springback function of this gasket. Secondly, on the bolted flange connection structure deformation coordination, flange in DIN2505 method based on analytic formula of deflection Angle is established in the flange joint without asbestos paper surrounded by metal gasket compression stress and radial distribution of parsing algorithm.
