API 5L X52 Pipes is used in the transportation of oil, gas and water in long pipes lines. These applications need special mechanical properties and standards and the American Petroleum Institute has laid out the standards for just these applications.

API 5L X52 Pipes
API 5L X52 Steel L360 Pipe

This particular grade has a composition of carbon, silicon, manganese, phosphorus, vanadium, niobium and titanium in the composition. There are two product specification levels out of which the 5L X52 PSL2 has the best range of mechanical properties. The X52 Steel has a unique combination of vanadium, niobium and titanium and therefore it is stronger, much corrosion resistant, ductile and durable. There are 5L X52 Equivalent Material in the market and Hi-tech Metal & Tubes is a manufacturer of all types and specifications of 5L products. We manufacture the L360 Pipes as well as other specifications. Our X52 Grade B pipes are used in petroleum, oil and gas and water line applications. The API 5L Grade X52 Carbon Steel Pipe is tougher and has a minimum yield strength of 52Ksi. There are variations such as 5L X52 Dsaw Pipes and the X52 Erw Pipes which are preferred with special requirements of the applications. You can also place any custom orders with us. Please contact us with your requirements and we are ready to serve you.
