This table is a starting point; the final choice depends on temperature, pressure, the exact process conditions and the design code. Our team can help confirm materials for your enquiry.

How we support each industry

Every industry has its own standards, documents and inspection practices. Oil and gas and refinery projects usually specify ASTM, ASME and API materials with owner specifications, NACE MR0175 / ISO 15156 requirements and third-party inspection. Power plants in India require IBR certification for boiler and steam piping. Pharmaceutical and food plants need hygienic finishes and full traceability. Chemical plants need material matched to the exact process fluid. We review the specification with each enquiry, confirm the material and testing, and supply mill test certificates and inspection documents to match.

Our office in Mumbai supplies customers across India and exports to the Middle East, Africa, Europe, Asia and the Americas – see the India and export pages.

More industries

Beyond the sectors above, we supply material for shipbuilding and marine engineering, pulp and paper, sugar and distilleries, cement and steel plants, mining and mineral processing, district cooling and HVAC, and general engineering and fabrication. If your industry is not listed, send us the service conditions and the specification, and we will suggest suitable materials and products.

Products for every industry

Our product range covers seamless pipes and tubes, welded pipes and tubes, flanges, pipe fittings, plates, sheets, round bars, rods and wires and fasteners, supplied with mill test certificates and with third-party inspection on request. Our company is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018.

For each industry page you will find the materials most often specified, the standards that apply and links to the products. Where a project needs several product forms in the same material – pipe, fittings, flanges and bolting in super duplex, for example – we can supply them together as one package, with matched documentation, which simplifies inspection and receiving at site.
