From upstream production and pipeline infrastructure to refineries, petrochemical complexes and other critical process systems, efficient, safe and uninterrupted transport of crude oil, natural gas, refined products, chemicals, steam and process fluids.
Seamless pipes are manufactured by piercing a solid cylindrical billet over a piercing rod to create a hollow tube. This is further rolled and stretched to the required Diameter and wall thickness. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable.
Due to seamless construction without any welds, the entire length of the pipe maintains uniform strength and structural integrity. With no weak points or welded joints they deliver superior performance under High Pressure and High temperature applications like boilers, Pipelines, refineries, nuclear etc.
Welded pipes are manufactured by rolling a flat steel plate or coil into a cylindrical shape and then weld joining the seams to form a Pipe. This manufacturing technique is the most efficient for producing a wide range of sizes and thicknesses especially in larger diameters. Common welding methods are Electric Resistance Welding (ERW), Longitudinal Submerged Arc Welding (LSAW) and Spiral Submerged Arc Welding (SSAW) selected based on the application and sizing requirements.
Welded pipes are generally more economical and faster to manufacture compared to seamless pipes making them suitable for medium to low pressure applications, structural fabrications, water service and general industrial requirements where pressure and or temperature is not a critical factor.
All our stock supplies are manufactured strictly in compliance to API, ASTM, ASME and other relevant & applicable international standards suiting to the requirements of major end users and international oil companies. Every product in our supply chain undergoes a comprehensive quality check and various nondestructive examinations including visual, ultrasonic testing (UT), radiographic/X‑ray testing (RT), hydrostatic testing (HT) and others as required ensuring full compliance, reliability and traceability from mill to project site.
