Located in the heart of Addis Ababa, Desta Steel is a trusted partner for industrial and construction projects across Ethiopia. We pride ourselves on supplying robust and reliable materials, including the industry-standard API 5L Grade B PSL1 Pipe. This pipe is a cornerstone for critical infrastructure, known for its dependable performance in demanding environments. Our commitment is to provide our clients with quality products that form the durable backbone of the nation’s growth and development, ensuring every project is built on a foundation of strength and integrity.
The API 5L Grade B PSL1 pipe is defined by a specific chemical composition that prioritizes strength and weldability, with a controlled carbon and manganese content. Mechanically, it offers a minimum yield strength of 35,000 psi (241 MPa), providing excellent resistance to deformation under pressure. This combination of a balanced makeup and reliable mechanical properties makes it a go-to choice for conveying oil, gas, and water, offering a perfect blend of durability and practicality for a wide range of piping systems.
