Flange blind is the connecting device of two large diameter pipes, usually two flange plates with a number of fastening bolts. Large flanges are made of steel flanges. Low carbon steel has a low plasticity, which can be hardened by adding a moderate amount of carbon.

Blind flange plate with the rapid development of domestic foreign minister pipeline construction, pipeline pressure test become an indispensable important link, in the before, during and after the test must be conducted for each section of the pipeline ball sweep line, generally for 4 ~ 5 times.
