API 5L PSL1 X56 Carbon Steel Seamless Pipes
The pipes supplied by GNEE undergo multiple inspections to ensure quality, with wall thicknesses ranging from 2mm to 30mm or even thicker.
API 5L X56 PSL1 carbon alloy pipe mainly contains alloy materials such as 0.16% carbon, 0.45% silicon and 1.65% manganese. The addition of these elements to the alloy enhances and improves the mechanical properties of the steel pipe.
API 5L PSL1 X56 Carbon Steel Round Pipe has poorer mechanical properties than API 5L PSL2, but has a more cost-effective price.
API 5L PSL1 X56 carbon steel seamless pipe is used in applications that require additional corrosion protection, thermal stability and high durability. API 5l X56m, for example, is used to transport oil, gas and water on long pipelines.
