Inconel Pipes & Tubes Supplier and Exporter in India
Kalpaturu Piping is a leading Inconel pipes and tubes supplier and exporter in India, serving critical industries across the globe from our well-stocked Mumbai facility. Inconel is a family of austenitic nickel-chromium superalloys engineered to perform where ordinary metals fail — at extreme temperatures, in corrosive chemical environments, and under intense mechanical stress. When exposed to elevated heat, Inconel forms a stable, self-repairing passive oxide layer that shields the base metal from further attack, maintaining both tensile strength and dimensional integrity across a wide service window. Our comprehensive Inconel product range covers every major grade including Inconel 600, Inconel 601, Inconel 625, and Inconel 718, supplied in seamless, welded, EFW, and ERW construction across schedules SCH 5 through XXS. Each pipe or tube order ships with full mill test certificates, chemical composition reports, and third-party inspection documentation, backed by ISO 9001:2015 certification. Whether you need a standard off-the-shelf size for a refinery turnaround or a custom-cut length for a precision aerospace assembly, Kalpaturu Piping delivers on time and to spec — worldwide.

What is Inconel Pipes & Tubes?
Kalpaturu Piping stocks and supplies Inconel pipes and tubes in a complete range of grades, sizes, and construction types — available as seamless, welded, EFW, and ERW. Inconel is a registered trademark of Special Metals Corporation for its family of nickel-chromium superalloys. What sets this alloy family apart is its ability to retain mechanical strength and oxidation resistance at temperatures where austenitic stainless steel and carbon steel lose structural integrity — making it the material of choice in jet engines, nuclear reactors, deep-sea oil risers, and high-temperature chemical reactors.
As part of our broader nickel alloy pipes and tubes in India product range, our Inconel pipes and tubes inventory spans the following types and construction forms:
- Seamless Pipes & Tubes — cold-drawn or hot-rolled, uniform wall thickness, ideal for pressure-critical service
- Welded Pipes & Tubes (ERW / EFW) — produced by high-grade welding of Inconel strip, suitable for lower-pressure and structural applications
- Cold Drawn Pipes & Tubes — precise OD and wall tolerances, superior surface finish
- Electropolished Pipes & Tubes — ultra-smooth internal bore for pharmaceutical and ultra-pure process lines
- Heat Exchanger Tubes — ASTM B163-compliant, thin-wall precision tubes for condenser and exchanger bundles
- Instrumentation Tubes — small OD, tight tolerance for instrument impulse lines and sampling systems
Our Inconel fittings, Inconel flanges, and Inconel fasteners are stocked as matched sets alongside Inconel round bars and Inconel plates and sheets, so procurement teams can source a complete piping system from one certified supplier.

Inconel Pipes & Tubes Grades
Inconel 600 Pipes and Tubes (UNS N06600 – W.Nr. 2.4816)
Inconel 600 (W.Nr. 2.4816) is the original nickel-chromium-iron workhorse — developed for furnace heat and general corrosion in one chemistry. Its 76% nickel content delivers excellent resistance to reducing environments, while 15% chromium handles oxidation up to 1093°C. Commonly found in heat-treat baskets, furnace muffles, chemical reactors, and nuclear steam generator tubing. Available in seamless and welded form per ASTM B167 / ASTM B517.
Inconel 601 Pipes and Tubes (UNS N06601 – W.Nr. 2.4851)
Inconel 601 adds 1.4% aluminium to the base nickel-chromium chemistry, pushing the oxidation ceiling even higher. That aluminium combines with chromium to form a dense, adherent alumina-chromia scale that resists spalling through repeated thermal cycling — ideal for industrial heating elements, radiant tubes, and petrochemical reforming furnaces. Standard: ASTM B167 (seamless) / ASTM B517 (welded).
Inconel 625 Pipes and Tubes (UNS N06625 – W.Nr. 2.4856)
Inconel 625 derives its strength from solid-solution hardening by molybdenum and niobium — no heat treatment required. Routinely specified for offshore risers, subsea umbilicals, seawater piping, and aerospace exhaust ducting because of its broad corrosion resistance spanning seawater pitting, crevice attack, and chloride stress-corrosion cracking. Standards: ASTM B444 (seamless) / ASTM B705 (welded) / ASTM B983 (large OD seamless).
Inconel 718 Pipes and Tubes (UNS N07718 – W.Nr. 2.4668)
Inconel 718 is the precipitation-hardened superalloy of choice where extreme strength meets high temperature. Its gamma-double-prime strengthening phase gives exceptional tensile and creep properties up to 650°C — making it the dominant material in jet engine discs, turbine casings, oil and gas downhole tools, and rocket motor components. Standards: ASTM B163 (seamless) / ASTM B829 (seamless) / ASTM B775 (welded).

- NACE MR0175 / ISO 15156 compliance documentation for sour service
Packing & Delivery
Proper packing prevents surface damage, thread contamination, and handling loss between our Mumbai warehouse and the project site — wherever in the world that may be.
Standard Packing:
- Pipes and tubes in standard lengths are bundled with polypropylene strapping and capped at both ends with plastic protectors
- Small-bore instrument tubes are coil-packed in wooden crates
- Large-bore pipes (>6″ NB) ship in wooden cradles with individual plastic sleeve wrapping
- Cut lengths and special pieces are packed individually in plastic film, placed in wooden cases or cardboard boxes depending on weight
Export Packing:
- All export lots use sea-worthy wooden crates with moisture-absorbing silica gel sachets
- Each piece is stencilled with grade, size, heat number, and specification for customs and site identification
- Export lots are packed per ISPM-15 (heat-treated timber) to comply with phytosanitary requirements
Delivery Lead Times:
| Order Type | Typical Lead Time |
|---|---|
| Ex-stock standard sizes | 1–2 working days (pan-India) |
| Ex-stock export orders | 3–5 working days (sea freight) |
| Cut-to-length / value-added | 5–7 working days |
| Non-standard / made-to-order | 30–45 days (subject to mill availability) |
Despatch from Mumbai covers pan-India by road and rail. Export shipments are handled through JNPT (Mumbai) with established freight forwarding partners to the USA, UAE, UK, Europe, Singapore, and Australia.
