Stainless steel pipe fittings have certain guiding significance for actual production.

Stainless steel pipe fittings are widely used. With the rapid development of science and technology, stainless steel pipe fittings are widely used in aviation, electronics, chemistry, atomic energy and other industries, and the quality requirements for stainless steel pipe fittings are getting higher and higher. Based on the forming characteristics and finite element principle of LD type three-roll cold rolling mill, the large-scale nonlinear finite element simulation software MSC. Marc was used to simulate the three-roll cold rolling process of 302 stainless steel pipe fittings.

The research results of stainless steel pipe fittings have certain guiding significance for actual production. The effects of different process parameters such as feed rate, swing angle, friction coefficient and opening angle on the rolling results were analyzed. The influence of different feed rates and opening angles on the rolling force and the influence of the angle of rotation on the deformation induced movement of the pipe are discussed. Through the comprehensive analysis of the simulation results, reasonable process parameters are obtained, which provides a basis for parameter optimization. It can significantly improve the mechanical properties, dimensional accuracy and surface quality of stainless steel pipe fittings.

The calculation of stainless steel pipe fittings is most commonly calculated according to the seamless pipe. This means that the product is placed flat on the ground and viewed from above as the head of a pipe. The theoretical formula of the seamless pipe knows how to calculate it. It is possible to fit onto this large flange, which is the theoretical data of a carbon steel product (outer diameter - thickness) X thickness X0.02466.

The wear behavior and wear mechanism of stainless steel pipe fittings under seawater were measured by microhardness tester under different friction conditions, and the variation of hardness under seawater sliding conditions was analyzed.
