Naing Steel stands as a trusted manufacturer and supplier in Naypyidaw, Myanmar, proudly producing Carbon Steel API X80 5L PSL 2 Pipes. We understand the critical demands of modern infrastructure, which is why our pipes are engineered for exceptional performance and unwavering reliability. Built to withstand extreme pressures, they are the go-to choice for ambitious energy and pipeline projects, ensuring the safe and efficient transport of vital resources across the region and beyond.
The composition of these pipes is precisely balanced, primarily of carbon with strategic additions of manganese and micro-alloys. This careful formulation gives the steel its remarkable strength and toughness. The X80 grade signifies a minimum yield strength of 80,000 psi, providing exceptional resistance to high internal pressures. Combined with excellent weldability and impact strength, these mechanical properties ensure the pipe’s integrity even in the most challenging environments and demanding applications.
