Flat welding flange connection device: Flat welding flange is the American standard flange connection device of two large diameter pipes, usually two flange pieces plus a number of fastening bolts. Low-carbon steel has good plasticity and low strength. It will become hard after adding a suitable amount of carbon element. The plasticity is reduced and the strength is increased. Generally, it is used on pipelines. .
Flat-welded flange connections are generally used on pipes. In that case, loosening the bolts can rotate the pipes on both sides, and then tightening them can make it easier to disassemble and assemble the pipes. The flange made of carbon steel is called carbon steel flange; the flat welding flange connection method is also the simplest connection method with cast iron pipes and steel pipes. Flange connection is suitable for connecting pipe fittings with pipe diameter from φ50-315mm. The performance characteristics of the matching flange: non-rigid connection, removable, tensile strength. The flange connection method is usually used as a detachable connection on the low-pressure transmission pipeline.
The demand for flat welding flanges is diverse, such as automobiles, construction machinery, rail vehicles, and shipbuilding industries. The above introduction about flat welding flanges is here, I hope it will be helpful to you.
