API 5L Grb LSAW Line Pipe

API 5L GRB straight seam line pipes are made from carbon steel through a hot rolling process. Due to the susceptibility of carbon steel to corrosion, they are typically subjected to anti-corrosion treatment on the surface. These pipes are used for transporting liquids and gases such as natural gas, petroleum, and liquefied gas. Generally, the diameter of API 5L GRB straight seam line pipes tends to be smaller, typically ranging from 33.4mm to 508mm.

GNEE Group supplies API 5L GRB straight seam line pipes to over 150 countries and regions globally. With high-quality steel pipes and professional services, we have become a renowned steel pipe supplier both domestically and internationally. If you need API 5L GRB straight seam line pipes, please feel free to contact us.
