Luke Steel proudly offers API 5L Grade L450 Pipes (X65) from its Houston manufacturing facility, engineered for the most challenging high-pressure and high-stress applications. Our L450 pipes are manufactured in accordance with international standards and tested stringently for mechanical performance, toughness, and reliability. Luke Steel, being a top U.S. supplier, offers timely solutions to pipeline contractors, energy companies, and industrial infrastructure developers, providing precision-forged products of superior quality and long service life.
API 5L Grade L450 Pipe consists of low carbon steel with manganese, chromium, and niobium additions for maximum strength and resistance to corrosion. The pipe has minimum yield strength of 450 MPa and tensile strength of 535–760 MPa. The pipe exhibits good weldability, fatigue life, and impact properties in extreme temperature and pressure variations. Quality control involves mechanical testing, impact testing, ultrasonic testing, and dimensional checking.
