来源:www.spiralweldedtubemill.com 发表时间:2019-10-28

  Spiral sewn submerged arc-welded steel tube (sy5036-83) for the transportation of pressurized fluid is mainly used for the pipelines for the transportation of oil and natural gas. High frequency helical welded steel tubes (sy5038-83) for pressure fluid transportation.

  The steel tube has strong plastic bearing capacity and is easy to be welded and shaped. General low-pressure fluid conveying spiral seam submerged arc welding steel pipe (SY5037-83) adopts double automatic submerged arc welding welding by one side or into the legal system for water, gas, air and steam, and other general low-pressure fluid conveying with submerged arc welding steel pipe is now commonly used standards of the spiral steel pipe can be divided into: SY/T5037-2000 (solid, also known as the common fluid conveying pipe with spiral seam submerged arc welding steel pipe), GB/T9711.1-1997 (national standard, also known as oil and gas industry conveying pipe delivery technical conditions in the first part: Pipe), api-5l (American petroleum institute, also known as pipeline pipe), SY/ t5040-92 (pile submerged spiral welded pipe)
