High Quality Wholesale Industrial A105 steel flange China factory supplier Manufacturer
What is A105 steel flange ?
A105 steel flange can be a collar, ring or solid disc that attaches to various pipe applications that allow or restrict the flow of liquids and gases. Pipe Flange installment is usually completed by welding the Flange onto the pipe but the Industry also offers Threaded and Lap Joint Flanges that don’t require welding for installment.
Flange connections are achieved by drilling equally spaced bolt holes into the Flange that align with the matching Flange and then fastened with bolts. Bolt hole patterns are determined by Industry Specifications or customer request. Flanges are usually manufactured based on Industry Specifications established by ANSI B16.5, ASME B16.47, MSS-SP44, AWWA-C207 or European standard EN1092.
