Most of these products are weighed by theoretical weight. In the calculation, the weight of the waterline, spigot, bolt hole, and chamfer is not reduced. First cut the middle plate into suitable slivers. The quality of the slivers is determined by the specifications of the large flanges.
The theoretical weight is calculated according to the following formula. Large flanges are made of stainless steel 304, 316, 316L, 201, 304L, 321 and other materials, carbon steel A3, Q235, 20#, Q345, A182, 16MN and other materials, alloy steel 12cr1mov, 15crmov910 and other materials.
Then use a ring rolling machine to make a circle, use a welding rod to weld the joints firmly, and perform X-spectrum inspections at the weld joints.
