Naing Steel stands as a trusted manufacturer and supplier in the heart of Naypyidaw, Myanmar, dedicated to delivering robust and reliable materials for the nation’s growing infrastructure. We take pride in our production of Carbon Steel A671 Gr CC 65 Pipe, a product engineered to meet the rigorous demands of critical applications. Our commitment lies in providing high-quality, durable piping solutions that builders and engineers can depend on for their most challenging projects, supporting development with locally-made excellence.
The composition of this carbon steel pipe is carefully balanced, primarily consisting of iron and carbon with controlled levels of manganese, phosphorus, and sulfur to ensure optimal performance. This specific chemistry grants the A671 Gr CC 65 grade its notable mechanical properties, including a minimum yield strength of 65,000 psi. This strength makes the pipe exceptionally resilient, capable of withstanding significant internal pressure and external loads without deforming, which is crucial for maintaining system integrity.
