We can help supply all of the Carbon Steel Seamless Pipes or linepipe supplies that your company needs for use in the oil or natural gas industries. API 5L Line Pipe Specifications for these pipes regulate usage for standard Grade A and Grade B pipes, with Grade X indicating stronger variants for drilling, production and transport requirements for offshore, arctic, deep well or harsher environments. Longitudinally welded steel pipes / Carbon Steel Seamless Pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances. All products are industry-standard conforming to or exceeding API, ASTM, ASME, ANSI and other national and international standards. API X Grades – some of the sturdiest pipes and tubing available designed for extreme environments or exceedingly high pressure environments
