We are proud to introduce Naing Steel, a trusted manufacturer and supplier based in the heart of Naypyidaw, Myanmar. Our specialty lies in producing high-quality API 5L Grade L390 pipes, engineered to meet the rigorous demands of the modern energy sector. With a firm commitment to precision and durability, we ensure our products provide reliable performance for critical infrastructure projects across the region and beyond, supporting progress with unwavering strength.
The composition of API 5L Grade L390 pipe is carefully balanced, primarily featuring carbon, manganese, and other micro-alloying elements that work in harmony. This specific chemistry grants the pipe its excellent mechanical properties, including a minimum yield strength of 390 MPa. This combination results in a product that is both incredibly strong and tough, capable of withstanding high internal pressures and harsh environmental conditions without compromising its integrity.
