STI is proud to publish that Qatar – Turkey pipeline project from the Iranian – Qatari South Pass we have supplied 300 ton API 5L ERW pipe in Year 2008 and after 10 years of supply there in no complaint in Piping material and we are receiving repeat orders from same customer.
ANSI / API 5L material is best to make Sour service pipe because it performs resistance in corrosive environments, Sour service steel pipe is used in oil and gas pipelines, if wrong material is used to manufacture this pipe so it may cause leakage of Oil, Gas and water those are natural resources and also seen explosion in certain conditions. So, it is very important to choose right material for Oil and gas pipe lines. API Tubular products are tested in different environments and very harsh conditions. Line pipes are fully certified material around the globe for transportation of oil, gas & water.

API 5L Pipe specification
ASTM A1024 / A1024M – 18 is the Standard Specification for Steel Line Pipe, Black, Plain-End, Seamless. This specification covers seamless, black, plain-end steel pipe for use in the conveyance of fluids under pressure. Pipe in sizes NPS 1 to 26, inclusive, as given in ASME B36.10M is included. API seamless steel pipe is the carbon steel pipe applied for pipeline transportation systems within the petroleum and natural gas industries are covered by ISO 3183. ISO 3183 standard specification for line pipe. BS EN 10208-2 indicate products with the same (and additional) strength levels and partly similar (but not identical) requirements as EN 10208-1 and EN 10208-2 and is with two additional annexes specifying deviating or additional requirements also published as API Spec 5L. This standard is not applicable to cast pipe. API 5L Pipe is a low carbon or ultra-low carbon micro alloy steel.
