Manufacturer profile & capability. Sumer Metal Industries Private Limited manufactures precision U-tubes in premium nickel alloys — Hastelloy C-22 (UNS N06022), C-2000 (UNS N06200), B-2 (UNS N10665) and B-3 (UNS N10675). Their production includes seamless and welded tube making, controlled annealing, pickling/bright finishes and qualified U-bend forming for shell-and-tube heat exchangers, condensers and high-purity process equipment. (Technical alloy details and uses referenced to official datasheets).
Quality & certifications. Tubes are produced to common industry standards (ASTM/ASME specifications for nickel alloys), undergo chemical analysis and mechanical testing, and are supplied with mill test certificates (MTCs). Typical product finishing options include annealed & pickled (AP), bright annealed (BA) and polished finishes; testing can include PMI/positive material identification on request.
Applications & performance. These Hastelloy grades are selected for extreme corrosion resistance: C-22 for combined oxidizing/reducing environments and chloride-bearing media; C-2000 for sulfuric-acid and ferric-ion environments (it contains deliberate copper to enhance acid resistance); B-2/B-3 alloys provide outstanding resistance to hydrochloric and other reducing acids. U-tubes are therefore ideal for chemical process heat exchangers, acid condensers, desalination, petrochemical units and specialty environmental service.
Export footprint. Sumer Metal Industries exports these Hastelloy U-tubes to major markets including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada and multiple African regions — offering logistic support, export documentation, and packing suitable for sea/air shipment. Lead-time, packing and export compliance can be provided per order. (Contact sales for country-specific compliance).
