API 5L Grade X56 PSL2 / PSL1 Pipe
Manufacturer of API 5L X56 Pipe & API 5L X56 PSL2 Pipe Material in India
X56 Pipe is a grade of pipe with a minimum yield strength of 56KPSI and it is stronger than the lower grades in this specification. The specification is monitored by the American Petroleum Institute and there are different grades in it. Steel India Company is a manufacturer and supplier of various grades of pipes in this specification such as the Api 5l X56m which are used to transport oil, gas and water through long lines of pipes. There are two major product level specifications in this grade.
The Api 5l X56 Pipe is the stronger version. The psl1 has lower mechanical properties than the API 5L X56m Psl2 and therefore is less costly. Our API 5L Grade X 56 products are used in petroleum industries, natural gas industries and domestic water supply for the transportation of these liquids. The L390 Pipe can also be used with the same applications. Our X56 Grade Casing is applicable where extra corrosion resistance, temperature resistance and pressure performance are needed. We produce pipes in different classifications such as the API 5l Grade X56a as well. We encourage our customers to contact us to get more information and pricing of pipes in this specification.
