Description
PL flange has the advantages of convenient material acquisition, simple manufacturing, low cost and wide application;
The advantage of PL flange is that it is easy to butt when welding and assembling, and the price is relatively low, so it has been widely used.

Characteristic
PL flange is the most common flange with pressure of pn2.5, pn6, PN10, PN16 and PN25.
The connection forms include single-sided welding and double-sided nut connection;
When welding, only one side welding is required, and it is not necessary to weld the inner mouth of the pipeline and flange connection. It is generally used for low and medium pressure pipelines.
Application
PL flange not only saves space and weight, but also ensures no leakage at the joint and good sealing performance.
It is widely used in chemical industry, construction, water supply and drainage, petroleum, light industry, refrigeration, sanitation, water supply and drainage and other basic projects.
