Carbon steel PJ-RJ flange loose flange is often used when the medium temperature and pressure are not high, but the medium is highly corrosive. When the medium is highly corrosive, the part of the flange in contact with the medium (flanging nipple) is made of high-grade corrosion-resistant materials, and the external part is clamped by the flange ring of low-grade materials to achieve sealing.
Size: 1 / 2 "- 600mm
Grade: 16Mn carbon steel
Sealing surface: RF, FF, RTJ
Pound class: 150Lb, 300lb, 1500Lb

Carbon steel PJ-RJ flange can save costs. When the pipe material is special and expensive, the cost of welding the flange of the same material is lower. It is convenient for construction. It is not necessary to align the flange bolt hole during connection, and it can also prevent the flange bolt hole from changing when replacing equipment in the future.
Carbon steel PJ-RJ flange is used in petroleum, chemical industry, nuclear power plant, food manufacturing, construction, shipbuilding, papermaking, medicine and other industries.
