Stainless steel flange can be a plate or ring to form a rim at the end of a pipe when fastened to the pipe.
A stainless steel blind flange is a plate for covering or closing the end of a pipe.
A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. There are many different flange standards to be found worldwide.
With b technical force, advanced equipment and skilled craftsmanship, XINHANG STEEL can supply various types of flanges and good quality is guaranteed. Various steel grades flanges are produced with complete specifications and supreme quality.
These SS flanges are widely applied to industries as petroleum, chemical industry, machinery, electric power, chemical fiber, papermaking, printing and dyeing, food and pneumatic parts etc.
The company is provided with complete inspection equipment and adopts technical standards for various types of flanges.
