Seamless Line Pipe Carbon Steel Pipe API 5L X42Q PSL2 Critical
Service
We offer a full range of high performance line pipe tailored to the
needs of the global oil and gas industry and the unique challenges
of transportation environments. Our welded and seamless line pipe
is used around the world to transport crude oil, natural gas and
natural gas liquids from producing fields to processing plants or
refineries.
To meet the oil and gas industry’s need for safe and dependable
onshore transportation, every joint of our line pipe is
manufactured at an ISO 9001 compliant facility to meet API 5L
standards. All product is tested in-house and delivered with
outstanding surface quality that is suitable for coating.
Standard: API 5L
