Quality is the hallmark of RPTPL’s strict adherence to the “No Compromise on Quality Policy” which is demonstrated in its stringent control over the procurement of raw materials and production process and faster delivery of finished products.
Followed with the conception of “based on honesty, win with quality, perfect service, customer first”, quality assurance has been an integral part of the company’s history. Quality assurance begins at the raw material stage itself. Material is inspected for mechanical properties, gauge variation, etc.
At Rishi Pipes and Tubes Pvt. Ltd., each product is processed according to the norms sequenced by the process control monitored through uncompromising quality control tests at every stage.
To ensure quality, every tube is checked for dimension by qualified personnel. We strictly adhere to Indian and international standards. The manufactured ERW tubes are made to undergo several tests like the Tensile Test, Hardness Test, Bend Test, Flattening Test, Straightness Test, Drift Test, and Cupping Test.
