Working to a clear vision, Heavy Metal & Tubes invests in state-of-the-art technology and top-tier talent to consistently deliver high quality products exceeding customer expectations. Specialising in seamless carbon and alloy steel tubes/pipes, as well as stainless steel seamless and welded variants, the company’s manufacturing journey begins with round bars. Offering tubes and pipes in both hot finish and cold finish conditions, HMT boasts a wide range of sizes in terms of outside diameter, wall thickness, and length. This capability positions it as a significant player in both the domestic market and overseas.

Brief history

“Heavy Metal & Tubes is a company with a considerable history and reputation,” begins Mr. Sandeep Kumar Mathur. Founded in 1978, it can be considered one of the pioneers of cold drawn tube manufacturing in India for carbon steel and alloy steel. Nearly a decade later in 1991, after having firmly established as a reliable producer, Heavy Metal & Tubes “HMT” invested in two new manufacturing facilities at Chhatral in Gujarat, fully dedicated to the manufacture of seamless carbon and alloy steel tubes and stainless steel seamless and welded tubes. These investments helped the company to not only be fully geared to meet the exponential growth in demand post the liberalization of the Indian economy in 1991 but also garner a significant share of the ever-growing Indian market.

Certainly one of the factors leading to the company’s resounding success and helping it to differentiate itself from the competition has been its ability to produce so many varieties of tubes and pipes in different grades, thicknesses, sizes, and lengths under one brand. “No one else does what we are doing in India,” says Mr. Mathur. “Hence we tag ourselves as a perfect blend of Quality and Integrity.”

Powering progress

In recent developments, Heavy Metal and Tubes has achieved a significant milestone with the successful manufacturing of arbor coil bends. These bends, made from ASTM A335 P9 grade steel, boast impressive specifications including a size of 101.4 mm OD × 5.74 mm WT and a bend diameter of 3000mm (with a radius of 1500mm). These arbor coil bends have been produced for a state-owned refinery.

Adding to the company’s advancements, Heavy Metal has taken a stride towards enhancing product quality with the commissioning of a new state-of-the-art controlled atmosphere bright annealing furnace. This investment enables the supply of even higher quality products without the necessity of acid treatment, ensuring better mechanical properties and surface finishes. With precise temperature control, inert gas atmosphere regulation, and efficient cooling, this furnace is able to meet the stringent demands of environments such as refineries, petrochemical facilities, power plants, and more.

Heavy Metal has successfully manufactured arbor coil bends for the first time in India.

Heavy Metal is poised to further strengthen its technological capabilities by introducing cutting-edge machinery for seamless tube production by November 2023. This initiative includes the integration of a state-of-the-art piercer machine and the expansion of its pilger machine fleet to 30 units for the Stainless Steel Division.

Accompanying these advancements is the incorporation of a heavy-duty draw bench for seamless carbon and alloy steel tubes with heavy wall thickness. This collective effort not only underscores Heavy Metal’s commitment to excellence and innovation but also positions the company to efficiently cater to industry demands without compromising on quality. Through these measured steps, Heavy Metal is well-positioned to continue its journey as a frontrunner in the industry, providing reliable and high-quality solutions for a range of applications.

Focus on the heat exchanger & boiler market

The company’s new state-of-the-art heat treatment furnace

Heavy Metal & Tubes seamless and welded tubes are largely used in shell & tube heat exchangers, but also find use in air-fin coolers, boilers, condensers, etc. Not surprisingly, the selection of tubes play a significant role in such equipment as they are used in such vital industrial segments as oil & gas, refineries, chemical & petrochemical, pharmaceutical, power plant, sugar, and fertilizer plants around the world.

The company is also capable of producing tubing up to 34 meters long, which is a significant factor that differentiates it from competition. Very few companies can do this in India. In addition to the above segments, Heavy Metal & Tubes also supplies tubes for the automobile industry, locomotives, defence sector, hydraulic and pneumatic systems, instrumentation and many more.

Quality assurance

“As is known,” says Mr. Mathur “we have been specialised in the manufacture of heat exchanger & boiler tubing for several years now. As these tubes play a very critical part and are at the heart of heat exchangers / boilers for heat transfer operations, it is not surprising that such tubes have to pass through a series of very stringent quality checks during the entire 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 packing and 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 and technical 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 laboratory tests with spectrometers, metallurgical investigations by metallurgical microscope and to determine grain size, corrosion, and microstructure. Both the plants have their own separate laboratory set-up with testing equipment. All tubes undergo hydro testing. Testing is carried out by trained, qualified personnel in compliance with the company’s strict ‘Quality Assurance Manual’.

One of the factors that differentiates it from the competition is Heavy Metal & Tubes’ ability to produce so many tubes and pipes in different grades, thicknesses, sizes, and lengths in the highest qualities.


The tests help to safeguard that the highest quality manufacturing standards can be maintained according to the intended application, technical delivery conditions and customer’s specifications. 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 & Ultrasonic testing.

It goes without saying that the mill and its products has been approved by 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 and end users to whom it regularly supplies products such as PEMEX, QP, SABIC, BHGE, Alfa Laval, BHEL, BPCL, CPCL, FACT, HPCL, IOCL, KFL, L&T, NFL, NPCIL, NTPC, TECHNIP, Reliance, SAIL, and many others.

The accuracy of the U-bend in tubes is ensured by precisely prepared jigs and fixtures.

Quality staffing

“Another factor that particularly stands out in our company is the high standard of technical competence of our staff,” says Mr. Mathur. “They are not only knowledgeable and skilled, having relevant technical degrees where appropriate, but are also loyal and committed.

Some of our employees have worked with us for anything from fifteen to thirty years. It says a lot about the culture that we have been able to hold on to them and this ensures that we have a great deal of skill and experience in-house to fall back on.

Specialization in heat exchanger & boiler tubes.

Certainly at a time when many companies find it difficult to fill technical vacancies, we do not experience this type of trouble. Young engineers clammer to join us and build their careers under our guidance.

They feel involved and challenged in contributing to our success and we likewise take a great interest in helping them shape their careers.”

Management is equally concerned for all employee’s health & safety along with environment hence been accredited with certification ISO 14001: 2015 and OHSAS 18001: 2007 & 45001.

HMT global presence

Roughly 60% of the Heavy Metal & Tubes products are sold within India. The remaining 40% is exported around the world. Today the company’s products reach as far as the Americas – Argentina, Canada, Brazil, Chile, Mexico, USA – and Europe – Belgium, France, Germany, Greece, Italy, the Netherlands, Spain, Turkey, and the United Kingdom, whilst in the Middle East their products are exported to Bahrain, Kuwait, Oman, Saudi Arabia, Qatar, UAE. In addition, they also have clients in South Korea, Japan, Singapore, Australia and several other countries. “The quality and services that we provide are very much appreciated by our clients,” says Mr. Mathur “as is seen by the large numbers of repeat orders we receive on a regular basis.”

With regards to the tubing market for heat exchangers, Heavy Metal & Tubes tend to concentrate its sales to four major regions of the world: India, South Korea in Asia, Italy in Europe, and North America, though manufacturers of heat exchanger equipment in the former Eastern Block countries of Europe and Russia as well as the Gulf nations are also equally important. Certainly not much has changed in the past ten years with regards to this market situation.

Strategy for the future

Heavy Metal & Tubes understands that enlarging a product range is a simple way to grow and better serve a customer base. The company is now entering the fittings and flanges market and very shortly will define the entire product range. “Our strategy for the future will be to continue to service the domestic and global markets to the highest possible quality standards with fully Indian origin material right from basic raw materials,” says Mr. Mathur. “As such, we expect our business to continue to expand as the demand for tubes and pipes in demanding applications continues to grow. In particular, we intend to concentrate increasingly on serving the manufacturers of heat exchangers / boilers. To this effect we have expanded our marketing team to aggressively cover this market. We intend to be there for our customers to ensure that their future is also a great success.”
