Sumer Metal Industries Private Limited manufactures, supplies and exports high-quality Stainless Steel 310 U Tubes for demanding high-temperature applications. As a full-service manufacturer the company provides mill-certified U-tube manufacture, precision bending, end-finishing and testing — delivering finished U-tubes ready for shell-and-tube heat exchangers, boilers, furnaces and process equipment. Sumer Metal Industries caters to both domestic Indian projects and international orders, specialising in large volume shipments and repeat OEM contracts.
Grade 310 stainless steel offers excellent high-temperature oxidation resistance due to its elevated chromium (≈24–26%) and nickel (≈19–22%) content; this makes SS 310 U-tubes ideal for service up to ~1000–1150°C in many applications where scale and sulfidation resistance are required. The alloy’s austenitic microstructure combines good creep resistance at elevated temperatures with workable forming and welding behaviour, enabling reliable U-bends and long service life in cyclic heating environments.
Sumer Metal Industries manufactures SS 310 U-tubes to applicable ASTM/ASME and international standards (mill test certificates, PMI/positive material identification on request, dimensional inspection and non-destructive testing where specified). Tubes are produced from hot-rolled or cold-finished feedstock, heat treated where required, and can be supplied in bright annealed or pickled/ passivated condition depending on customer needs. Custom bend radii, total tube length and end preparation (bevels, plain ends) are available for turnkey heat exchanger builds and retrofits.
Typical industries and applications served include petrochemical furnaces, heat treatment equipment, high-temperature process heaters, power generation, refractory linings, and specialized food-process equipment where periodic high temperatures and carburizing atmospheres occur. Sumer Metal Industries exports SS 310 U-tubes across Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and several regions in Africa — supplying both project and distributor orders with export documentation (COO, MTC, packing list) included.
