Heavy Metal has successfully manufactured arbor coil bends for the first time in India.
Quality control Heavy Metal & Tubes must prioritize the quality of its work in order to create a successful route forward. As a result, it has obtained PED and ISO 9001:2015 accreditation. Additionally, the business has put in place a quality assurance system that encompasses every phase of production, from raw materials, cold working, and heat treatment, to packing and shipping. Every component of this system complies with all national and international codes, as well as, if necessary, the specific quality and technical needs of each customer. The company’ s quality control department works independently of the manufacturing shop. Additional testing facilities that ensure quality include a wide range of air-under-water, eddy current, flaring, flattening, hardness, hydro, reverse bend, tensile, ultrasonic, and laboratory tests with spectrometers and metallurgical investigations by metallurgical microscope to determine grain size, corrosion, and microstructure. These testing facilities are also required by code requirements and mandatory supplementary tests. Each plant has a distinct laboratory setup complete with testing apparatus. Hydro testing is done on every tube. Personnel with the necessary training and qualifications conduct testing in accordance with the organization’ s stringent“ Quality Assurance
The company is capable of providing a wide variety of special coil bends to serve their customers’ every requirement.

Manual.” The tests aid in ensuring that, in accordance with the intended use, technical delivery circumstances, and customer specifications, the highest manufacturing standards may be upheld. In addition, the production sites have also been equipped with reliable testing and measuring equipment for destructive and non-destructive testing such as Inter-granular corrosion testing, eddy current testing and ultrasonic testing. It goes without saying that a number of important inspection organizations, including ABS, Bureau Veritas, DNV, EIL, IBR, LRIS, Intertek, PDIL, SGS, and TÜV, have authorized the mill and its products. A wide range of significant clients and end users, including KNPC, PEMEX, QP, SABIC, BHGE, Alfa Laval, BHEL, BPCL, CPCL, FACT, HPCL, IOCL, KFL, L & T, NFL, NPCIL, NTPC, TECHNIP, Reliance, SAIL, and several more, have also given the organization their approval.

Investing in people According to Mr. Mathur,“ the high standard of technical competence of our staff is another factor that particularly stands out in our company.”“ They possess not just technical degrees when necessary but also loyalty and commitment in addition to knowledge and expertise. Some of our staff members have been with us for fifteen or thirty years. The fact that we have managed to retain them speaks volumes about our culture and guarantees that we have a wealth of knowledge and expertise on staff. At a time when many organizations are struggling
