ANSI B16.5 Q235 RF MF PN40 Carbon Steel Flanges For Water Industry
ANSI B16.5 Carbon steel Q235 RF/MF PN40 Carbon steel PJ-SE flange
Description
Carbon steel PJ-SE flange, It is connected by welding, but the flange is sleeved on the auxiliary components welded with the pipe, and then the auxiliary components and gaskets are pressed by connecting bolts to achieve sealing, while the flange itself does not contact the medium. The flange can be rotated, easy to align with the bolt hole, and easy to install on large-diameter pipeline.

Characteristic
Carbon steel PJ-SE flange is suitable for places where the pipeline needs to be frequently disassembled for cleaning or inspection, or where it is only necessary to rotate the flange without rotating the pipe when aligning the flange bolt hole. When using this flange joint, the material of flange accessory components is the same as that of pipe, and the flange material can be different from that of pipe.
Application
Carbon steel PJ-SE flange is mainly used in petroleum, chemical industry, nuclear power plant, food manufacturing, construction, shipbuilding, papermaking, medicine and other industries.
