We understand that the quality of a product is of paramount importance in order to achieve the satisfaction of our clients. All our steel pipe fittings such as stainless steel flanges, stainless steel pipes etc. are fabricated under the strict supervision of our quality control engineers, who monitor the entire manufacturing process.
Quality Assurance Manual: The quality assurance manual is designed to frame the controls and systems that need to be followed while manufacturing pipe fittings viz butt welded socket welded and threaded series. This works as an audit mechanism that will be in operation throughout the manufacturing process, so that end-product is in conformation with the various national and international quality standards, and also are in accordance with the specifications provided by our clients.
Our quality control engineers maintain records of all the inspections and tests carried by inspection engineer who stringently adhere to the quality assurance manual and conduct several chemical and physical tests as per the laid codes and norms.
Material Control System:We purchase all the raw material directly from the mills or from authorized dealers. The entire raw material is checked for optimum quality on visual and dimensional parameters. The raw material is checked with the test certificate provided by the manufacturer to check the quality of each lot as per the applicable codes for obtaining satisfactory chemical report. A batch number is assigned and punched on each lot.
Process Control System:The raw material might be in the form of pipes, plate, rod, forgings, billets and others. Before cutting the material, a batch number is allotted on every single piece that is cut from the parent material. After forging, each piece is re-stamped in case the batch number is not visible.
Testing:
Mentioned below are some of the parameters on which our quality control engineers check the quality of our range of steel pipe fittings:
- Tensile Test: A test to check the tensile strength is performed on a sample or test coupon from fitting or starting material as per the specification as desired by our clients. all the tests are performed in third party approved labs and the physical report of the product is mentioned in the material certificates issued to the clients.
- Hardness Test: A sample of each lot or batch is checked for hardness (10% materials from each heat treatment batch). We have an in-house hardness machine that is calibrated periodically by calibration agency. The results obtained are documented and incorporated in certification.
