The calculation of stainless steel pipe fittings is usually calculated by seamless pipe. This means that the product is laid flat on the ground and viewed as the head of a pipe from above. After the theoretical formula of seamless pipe knows how to calculate it, It can be set on this large flange, which is the theoretical data of a carbon steel product derived from (outer diameter-thickness) X thickness X0.02466.
The wear behavior and wear mechanism of stainless steel pipe fittings under seawater, using a microhardness tester to test the surface microhardness under different friction conditions, and analyze the changing law of hardness under seawater sliding conditions.
