API 5L X46 Pipe

API 5L X46 Pipes comes under the American Petroleum Institute specifications. There are different grades within the specification and the X range indicates the minimum yield strength needed for the pipes in the grades. X46 has a minimum of 46KPSI yield strength. The Api 5l X46 Pipes is relatively stronger than most other grades. Steel India Co. is a manufacturer and supplier of these pipes in different product specification levels. There are two levels and the psl2 has better mechanical properties than the psl1. The Api 5l X46 Psl2 is used in oil, gas and water transmission lines. Since these pipes are used for extended distances, these are called the line pipes.

We produce the seamless and the Api 5l X46 Erw Pipes as well. The ERW pipes are used for strength and welding ease where the seamless pipes are used for the accuracy of installation and the precision dimensions of the pipelines. This material can also be used in pipes fittings such as special couplings. The Api 5l X46 Psl1 is slightly of lower performance but with affordable price, so that it is the most used of Api 5l Gr X46 pipes. We also produce Api 5l X46 Equivalent materials for customer needs. Please contact us to know more about these products or purchases.
