API 5L X56m PSL2 ERW Pipe and X56 Seamless Pipe supplier in India
The API 5L X56 specification covers welded, ERW, and seamless pipes, mainly used for oil and natural gas transportation. We are one of the biggest manufacturers of API 5L X56 Pipe in India. Here, you will get API 5L X56 Pipe in different sizes, shapes, and finishes. Clients can let us know their requirements when placing orders, and we will customize the API 5L X56m pipelines according to their needs. The X56 Pipe is available in two product levels, namely PSL1 and PSL2. Both the API 5L X56m PSL2 and PLS1 levels are found in seamless and welded pipes. However, for the API 5L X56 PSL2 material, the steel shall be killed and melted as per fine grain practice. Also, the plate or coil used for X56 Grade PSL2 Pipeline should not contain any repair welds.
The API 5L Grade X56 Pipe needs to go through several certification tests to ensure its overall quality. We conduct the hydrostatic test on the API 5L X56 Seamless Pipe to ensure no leakages through the seam. The test also confirms no leakage throughout the body of the X56 ERW Pipe. We also conduct a bend test on API 5L X56 PSL1 Welded Pipe to ensure no cracks are present there. It also confirms that the weld of API 5L Grade X56 High Yield Pipe has no openings. Many API 5L Grade X56 PSL2 Epoxy Coated Pipe of various sizes and grades require the flattening test. The test needs to be done on the body when it comes to the API 5L X 56 Carbon Steel Seamless Pipe. For the given size and grade of API 5L Gr X56 HIC Pipeline, the energy absorbed should match the required value.
The X56 Steel Nace Pipe is also famous for its good mechanical properties. The API X56 Carbon Steel Line Pipe comes with a minimum yield strength of 386 MPa and minimum tensile strength of 489 MPa.
The chemical composition of the X56 Carbon Steel Pipe will include elements like carbon, silicon, and manganese. The API 5L X56 Grade B LSAW Pipe also contains trace amounts of sulfur, phosphorus, niobium, titanium, and vanadium in the alloy. All the above elements in the API 5L X56 SCH 40 DSAW Pipe helps in enhancing its mechanical strength to a great extent. The Grade X56 PSL2 Spiral Pipe now comes with improved tensile strength, toughness, and hardness.
The Grade X56 PSL1 Pipe Line is also known for its corrosion resistance properties. The X56 Grade PSL1 Line Pipe is well resistant to sulfur-related stress cracking and sour services. For the API 5L Grade X56 PSL2 Epoxy Coated Pipe, the coating can either be done internally, externally, or by combining both. Different types of coatings are available for API 5L Grade X56 PSL1 Sour Service Pipe like hot or cold galvanized, black paint, anti-corrosion oil, etc. Clients can contact us directly with their Grade L390 X56 Spiral Welded Pipe requirements, and we will deliver the consignment to their doorstep.

What is API 5L X56 Pipe?
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.
