Titanium Pipes
Steel Pipe & Tubes has been a leading supplier of Titanium Pipes solutions.
Titanium pipes are hollow cylindrical products crafted from titanium, a metal well-known for its high strength, light weight, and remarkable resistance to corrosion. Owing to their superior strength-to-weight ratio and ability to perform reliably under extreme temperatures and pressures, they are widely utilized in industries such as aerospace, chemical processing, and medical. Typical uses include heat exchangers, condensers and high-pressure systems where conventional materials often fall short in durability and performance.

What Are Inconel 600 Pipes / Tubes?
Inconel 600, also known as Alloy 600, UNS N06600 and W. Nr. 2.4816, is a solid‑solution nickel chromium iron alloy designed for strength and stability across a wide temperature span. It resists chloride‑ion stress corrosion cracking better than common stainless steels and offers reliable oxidation resistance in air, steam, and flue gases. The alloy is non-age hardenable and is supplied in annealed or solution‑annealed condition for good fabricability, bending, and cold working.
Corrosion and high‑temperature behavior:
- Performs well in caustic alkali solutions, neutral salts, and many organic media. Not preferred for strong oxidizing acids such as nitric without inhibitors.
- Good resistance to dry chlorine and hydrogen chloride at moderate temperatures, and to carburizing or nitriding atmospheres often found in furnace service.
- Retains strength and toughness from cryogenic temperatures up to high service temperatures with a stable austenitic matrix.
Typical end uses Heat exchanger and condenser tubing, pickling baskets, chemical process piping, superheater and reheater tubes, furnace tubes and muffles, nuclear steam generator components, marine hardware, and high‑temperature instrumentation.
Types & Popular Variants of Titanium Grade 2 Pipes
Titanium Grade 2 pipes and tubes are available in multiple forms to suit diverse industrial applications. From seamless and welded options to ERW, EFW, DOM, and custom shapes, these variants ensure strength, durability, and design flexibility.

Frequently Asked Questions About Titanium Seamless & Welded Pipes
Titanium piping is often chosen for industries that deal with highly corrosive environments, especially when chlorides are present. These systems perform well in applications such as alkaline solutions and inorganic salt handling, making them reliable for demanding chemical processes.
Yes, titanium pipes are considered safe because the metal is biocompatible, meaning it can be used in medical implants without harmful effects. They also have an excellent strength-to-weight ratio, making the pipes both strong and lightweight.
Titanium is as strong as steel but much lighter, which is why it is commonly combined with metals like aluminium, molybdenum, and iron to form alloys. These alloys are widely used in aircraft, spacecraft, and missiles, where both lightness and the ability to withstand extreme heat are essential.
No, titanium is generally more costly than steel. Its higher price comes from the complex processes required to extract and refine it. However, because it is lightweight and durable, it is preferred in fields like aerospace and advanced automotive engineering.
