Hastelloy C22, C2000, B2 and B3 clad tubes from Sumer Metal Industries Private Limited are engineered for the most aggressive chemical and process environments. Manufactured using precision cladding techniques, these tubes combine a corrosion-resistant Hastelloy overlay (or solid Hastelloy construction where specified) with a cost-efficient backing/parent material to give excellent resistance to pitting, crevice corrosion and stress-corrosion cracking while keeping fabrication and installation costs down. These clad tubes are widely used in chemical processing, pharma, desalination, offshore oil & gas, and pollution control equipment.
Sumer Metal Industries supplies these clad tubes in annealed and cold-worked tempers with full traceability and material certificates (MTCs) compliant with international standards. Typical product testing includes PMI/positive material identification, hydrostatic testing, dimensional inspection, visual & NDT as per customer spec, and packing for sea export. The company exports to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and multiple countries across Africa, supporting both small bespoke orders and large project volumes.
Hastelloy C-22 (UNS N06022) clad tubes deliver a unique balance of high chromium and molybdenum plus tungsten that gives broad resistance to both oxidizing and reducing media — making C-22 the go-to alloy where mixed or uncertain chemistries are expected. Hastelloy C-2000 (UNS N06200) adds a controlled copper addition to further increase sulphuric-acid resistance while retaining excellent resistance to oxidizing conditions. Hastelloy B2 (UNS N10665) and B3 (UNS N10675) are nickel-molybdenum alloys optimized for extremely reducing environments (strong hydrochloric and sulfuric acids) — B3 is an improved, more thermally stable evolution of B2. Use these grades where service chemistry is known to be strongly reducing.
Sumer Metal’s clad tubes are manufactured to tight dimensional tolerances and are offered in ranges of outside diameters and wall thicknesses to suit heat-exchangers, condensers, reactors and piping replacement applications. Typical lengths are supplied as random cut lengths, single-piece lengths up to project requirements, or precision cut and chamfered ends — and all exports are packed to withstand long-distance sea and air freight. Technical support for weld procedures (WPS/PQR), post-weld heat treatment advice and compatibility checks with customers’ base materials are provided as part of the supply package.
