Application of carbon steel flange in making steel plate

Carbon steel flange itself compact structure, simple structure, maintenance is also very convenient, sealing surface and spherical surface is often in a closed state, not easy to be washed by the medium, easy operation and maintenance, suitable for solvents, acid, water and natural gas and other general working medium. A flange made of carbon steel is called a carbon steel flange. The surface of carbon steel flange itself is flat and smooth, no burr, no scratch, no warping concave and convex conditions.

Steel plate should be ultrasonic inspection, no delamination defects should be cut along the rolling direction of steel strip, bending butt welding into a ring, and make the surface of steel ring cylindrical. Butt welds with neck flanged rings shall not be machined directly from steel plates, and full penetration welds shall be used. The use of carbon steel bolts do not necessarily need to add insulation gasket and barrel, plus insulation gasket and barrel is only used for the possibility of electable or pipeline fluid is flammable and explosive occasions, this occasion to choose stainless steel bolts also add insulation gasket and barrel.
