At Om Steel Tubes Limited, we employ a meticulously engineered manufacturing process to produce superior quality stainless steel tubes.
Our approach combines advanced techniques in welding, cold drawing, and bright annealing to ensure that every product not only meets but exceeds industry standards.
Below, we detail the sophisticated processes that define our production line, from initial material handling to the final stages of tube finishing.
Welding:
Our tubing is made from cold-rolled metal strips formed into tubes and welded without fillers, ensuring a homogeneous composition.Â
The process includes precise thickness control and visual inspection for defects, offering cost-effective alternatives to seamless tubing.Â
Tubes undergo online eddy-current testing for defect-free assurance.
Cold Drawing:
Tubes are drawn through a die to reach desired sizes, with intermittent bright annealing between draws to maintain ductility and quality.Â
The weld area blends seamlessly with the parent metal, detectable only through specialized testing, ensuring uniform properties throughout.
Bright Annealing:
Our tubes are bright annealed in advanced furnaces that prevent oxidation and scaling, preserving their bright surface and corrosion resistance.
This process, using furnaces imported from Japan, ensures optimal solutionizing of the matrix and enhances tube quality and appearance.
Straightening & Cutting:
The stainless steel tubes are precisely straightened to remove any bends or kinks, ensuring uniformity.
They are then cut to specified lengths with high accuracy to meet exact customer requirements.
Air Under Water Pressure Testing for leakage in Coils:
Coiled tubes undergo air-under-water pressure testing for leakage, where they are pressurized with air and submerged in liquid and checked for air bubbles.
This method detects any leaks or defects, ensuring the coiled tubings free of any micro punctures.
Air Under Water in Length Testing:
Individual Very THIN WALLED tube lengths are tested by submerging them in water after pressurizing with air.
This process identifies leaks or micro punctures, guaranteeing each tube meets stringent quality standards.
Hydro Testing:
Individual tubes other than Very Thin wall are subjected to hydrostatic pressure testing to verify their strength and leak in weld joint.
This rigorous testing ensures the tubes can withstand high-pressure applications without failure.
