Quality assurance
“As is known,” says Mr. Mathur “we have been specialised in the manufacture of heat exchanger tubing for some time. As these tubes play a very critical part in the heat exchangers themselves and in heat transfer it is not surprising that such tubes have to pass some very stringent quality standards during the production process.”
Building a pathway towards success therefore necessitates that Heavy Metal & Tubes places great emphasis on the quality aspects of its work. It has therefore attained ISO 9001:2015 and PED accreditation. Moreover, the company has implemented a quality assurance system that covers all production stages from raw materials, cold working, and heat treatment, right through to dispatch.
All components of this system correspond to the requirements of national and international codes, as well as, where needed, to individual customer’s quality assurance requirements.
The company’s quality control department works independently of the manufacturing shop.
Quality is further guaranteed by a wide range of testing facilities, as per code requirement, mandatory & supplementary test including: air-under-water, eddy current, flaring, flattening, hardness, hydro, reverse bend, tensile, ultrasonic, as well as incorporating laboratory tests with spectrometers, metallurgical investigations by metallurgical microscope, and experiments to determine grain size, corrosion, and microstructure. Both the plants have their own independent QC lab and have their separate equipment. All tubes, moreover, undergo hydro testing.
Testing is carried out by trained, qualified personnel in compliance with the company’s strict ‘Quality Assurance Manual’. The tests help to safeguard that the highest quality manufacturing standards can be maintained according to the intended application, technical delivery conditions, or customer’s specifications. In addition, the production sites have also been equipped with reliable testing and measuring equipment for destructive and non-destructive testing.
It goes without saying that the mill and its products has been approved by some very significant inspection agencies including: ABS, Bureau Veritas, DNV, EIL, IBR, LRIS, Intertek, PDIL, SGS, and TÜV, among numerable others. Additionally, the company is approved by a large number of major customers to whom it regularly supplies products such as Alfa Laval, BHEL, BPCL, CPCL, FACT, HPCL, IOCL, KFL, L&T, NFL, NPCIL, NTPC, Reliance, SAIL, and many others.
