For over a decade, Naing Steel has stood as a pillar of industrial strength in Naypyidaw, Myanmar, dedicated to fueling the nation’s growth. We take immense pride in our role as a trusted manufacturer and supplier of critical pipeline infrastructure, with our API 5L Grade L290 pipes representing the core of our commitment. These pipes are engineered to meet the most demanding challenges, ensuring the safe and efficient transport of vital resources across our developing landscape. Our focus is on delivering not just a product, but a promise of reliability and enduring quality to every project we support.
The API 5L Grade L290 pipe is crafted from a specific steel composition that balances strength with weldability, primarily relying on carbon and manganese. Its true value lies in its mechanical properties, offering a minimum yield strength of 290 MPa, which allows it to withstand significant internal pressures and external loads. This combination of a robust chemical makeup and proven mechanical performance makes it a go-to choice for engineers who require a pipe that is both strong and practical for fabrication in the field.
