Our Forged Pipe Fittings are manufactured using advanced forging processes and undergo extensive quality checks to ensure flawless dimensional accuracy, durability, and long service life. Each fitting is thoroughly inspected using key NDT techniques such as radiographic testing (RT), ultrasonic testing (UT), hydrostatic testing, and visual/dimensional examination. We also perform detailed chemical composition analysis and mechanical property testing to ensure material compliance with strict industry standards.
Throughout the forging and finishing stages, every forged fitting is monitored closely to eliminate defects such as misalignment, surface irregularities, and wall-thickness variations. This ensures perfect joint integrity and high-performance reliability in pipelines carrying high temperatures, pressures, and corrosive media. All our forged fittings fully comply with ASME, ASTM, MSS-SP, and related global specifications, making them a preferred choice for critical piping systems worldwide.
