1, the steel plate should have no lamination defects;
2, should be cut into strips along the rolling direction of steel, through bending welding into a ring, and the appearance of the steel constitutes the cylinder of the ring.
The steel plate can not be directly processed into a neck flange;
3. The butt weld of the ring should be full penetration weld;
The selection of carbon steel bolts does not necessarily require insulation gaskets and bushing. Insulation gaskets and bushing are only used when the pipe liquid is flammable and explosive. Insulation gaskets and bushing should also be added when stainless steel bolts are used in such occasions.
