API 5L Grade B Pipe




API 5L Grade B Pipe belongs to a specification that covers line pipes for the transportation of oil, gas and water in different applications. The American Petroleum Institute monitors the specification and Steel India Co. is a manufacturer of pipes under this specification. There are different grades of this specification such as the Api 5l Gr B Pipe. The different grades apply for different applications. There are grades A, B and the X range of grades. The Api 5l Grade B Seamless Pipe is one of the most used grades in this specification.

The applications can have seamless pipes ranging from ½ inches to 60 inches or the Electric Resistance Welded pipes up to 24 inches. There are also the SAW or LSAW pipes which could range from 16 inches to 100 inches. Our Api 5l Grade B Erw Pipe is used for great strength. The Api 5l Grade B Psl1 Material can be of different grades of steel such as the A53, A333, A179 and so on. Depending on the application requirement the Api 5l Grade B Psl2 or Psl1 pipes could be manufactured from different material grades. You can place any orders with us for any type of Api 5l Grade B Carbon Steel Pipe. Please contact us for further information and price lists.
