API 5L Seamless Pipe

API 5L Seamless Pipes belongs to a specification that is governed by the American Petroleum Institute and there are different grades within this specification. We are a leading Api 5l Pipes Manufacturer In India and we supply to various stakeholders. Steel India Co. is in the business for long enough and has mastered the production, stocking and distribution of these pipes in different sizes, grades and quantities. The Api 5l Erw Pipes is electric resistant welded and is stronger than most other pipes.

These pipes are used mostly in gas, oil and water transportation or conveying industries. Their sizes range from very low to very high that the only limiting factor is the capacity of the manufacturer. Since we are a leading manufacturer, we take all custom order for Api 5l Psl1 and the Api 5l Psl2 pipes grades as well. The psl 1 and 2 define the product specification levels where the psl2 has some higher mechanical properties. The psl2 also mandates additional testing procedures to qualify. We supply the Api 5l Welded Pipes in both product specification levels for different applications. We encourage customers to contact us with any Api 5l Line Pipes requirements and we are ready to serve you.
