Sumer Metal Industries Private Limited manufactures and supplies premium Inconel 800, 800H, and 800HT clad tubes, engineered for high-temperature corrosion resistance and long-term stability. Our clad tubes combine the superior oxidation and carburization resistance of Inconel 800-series alloys with a robust base pipe (carbon steel or stainless steel) to deliver cost-effective, corrosion-resistant tubing ideal for heat exchangers, reformer coils, furnace components, and petrochemical service. Each tube is produced under strict quality controls — including visual, dimensional and non-destructive testing — to assure metallurgical bond integrity between the Inconel cladding and the substrate.
As exporters, Sumer Metal Industries has established logistics and compliance capabilities to supply Inconel 800-series clad tubes to customers in Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and multiple regions across Africa. We support export documentation (COC / MTC, Mill Test Certificate, packing list, export packing, and customs paperwork) and can tailor packing and inspection to meet import regulations and project specifications in each market. Our trade team coordinates lead times and shipping routes to minimize downtime for project schedules.
The Inconel 800 family offers a spectrum of performance: Alloy 800 (good general elevated-temperature strength and resistance to oxidation), 800H (higher creep-rupture strength due to controlled carbon for improved high-temperature tensile strength), and 800HT (optimized for even higher temperature strength through stabilization and mechanical treatment). When used as cladding, these alloys protect the underlying carrier tube from aggressive process environments — such as sulfur-bearing atmospheres, high-temperature steam, and carburizing gases — while reducing the overall cost compared with full solid alloy tubing.
Sumer Metal Industries provides clad tubes in a wide range of dimensions, wall thicknesses, and lengths; we can manufacture to customer drawings and international standards. Our production processes include surface preparation, metallurgical bonding by explosive/roll bonding or weld overlay (as specified), precision finishing, and final testing. We also provide post-fabrication services such as cutting to length, end prepping (beveling, threading), hydrostatic testing, and third-party inspection upon request.

❓ Frequently Asked Questions (FAQs)
Q1: What is the difference between Inconel 800, 800H and 800HT clad tubes?
A: Alloy 800 is the base alloy with good high-temperature oxidation resistance. 800H has controlled higher carbon for improved creep strength at elevated temperatures. 800HT is stabilized and treated for higher long-term strength at still higher temperatures. All three can be used as cladding materials to protect a base pipe; selection depends on operating temperature and creep/rupture requirements.
Q2: What documentation and tests are supplied with Sumer Metal Industries clad tubes?
A: Standard exports include a Mill Test Certificate (MTC) showing chemical analysis and mechanical test results; non-destructive testing (visual, PT/UT as required), dimensional inspection reports, and third-party inspection reports on request. Custom documentation for import requirements (e.g., EUR1, certificate of origin) can be provided.
Q3: How should I specify clad tube thickness and base pipe for my heat exchanger project?
A: Specify the required corrosion-resistant cladding thickness (based on design life and corrosivity), the base pipe material (for strength and cost), OD/WT tolerances, end preparation, and testing requirements. Sumer Metal's technical team can review operating temperature, media, and pressure to recommend the correct alloy (800/800H/800HT), cladding method and thickness.
