API 5L X56 Pipe

API 5L Grade X56 PSL2 Seamless Pipe, API 5L X56M PSL2 Casing suppliers

The API 5L X56 pipes supplied by us are commercially available in either welded or in a seamless form all across India. This carbon steel based L390 Pipe is considered to be a very popular choice amongst several of our buyers. There are many reasons for this. Firstly, in comparison to the PSL 1 pipes of this specification, the API 5L X56m PSL2 has a much stricter quality check. Which means that the pipe produced needs to not only adhere to the mechanical but also to the chemical requirements of the ISO standard API 5L specification. Hence, the API 5L X56 PSL2 pipes are known to offer a much better performance in comparison to the PSL 1 pipes of the same specification. Secondly, the X56 Steel Pipe Properties of the pipes we stock include improved resistance to corrosion along with a significantly higher tensile strength properties as opposed to the other more conventionally used steels. In relation to the above point, we supply FBE Coated API 5L X56 PSL1 pipes. These FBE coated API 5L Grade X 56 pipes can be used for demanding piping systems for the transportation of water, steam, oil as well as gases. Therefore, the API 5L X56 Pipe that we supply proves to not only be a good quality and but also a cost saving option for all our suppliers. Which is why the specified carbon steel based API 5L X56m is used in various key industries like chemical, petrochemical along with oil and natural gas.
