API 5l X80 Pipe

API 5L X80 Pipe is a high-strength carbon steel pipe used for transporting oil, gas, and other fluids under high pressure and temperature. These pipes are made using a powerful chemical combination of carbon, manganese, vanadium, and other components to provide exceptional durability and resistance to corrosion. Available in seamless, ERW, and welded types, API 5L X80 pipes come in sizes ranging from 1/2NB to 60NB and come in end types include plain, threaded, and beveled. They offer high yield strength of 290 MPa and tensile strength up to 540 MPa, making them a top choice for critical applications. Multi Metals India is a trusted supplier of API 5L X80 pipe, offering reliable solutions for industries across India.

Carbon Steel Seamless Pipe

These pipes are widely used in oil and gas, petrochemical plants, power generation, and pressure vessels. For high-pressure needs, the API 5L X80 PSL2 pipe delivers better mechanical properties and tighter tolerance. While seamless pipes are resistant to stress and cracking, welded pipes are best suited for low-pressure systems. API 5L X80 guarantees performance and longevity whether it is used in refineries, food processing or fertilizer manufacturing. We focus on supplying high-quality pipes at competitive prices to meet industry demands with precision and reliability.
