1. Quick Detail:
Tube and pipe welding flanges are interconnected parts, connected
to the pipe end. There welded flange apertures, so that the two
flange bolts tightly connected. Room sealed with gaskets. Welding
flange is a disk-shaped parts, the most common in the pipeline
Welding flange connection is the two pipes, fittings or equipment,
each mounted on a first welding. Welding between the two, with
flange pad, fastened together with bolts to complete the
connection. Welding is important to connect a high-pressure
pipeline construction. Welding flange connections easy to use, able
to withstand greater pressure. Welding flange is widely used in
petroleum, chemical, natural gas, power, metallurgy pipelines.
