We manufacture and supply Hastelloy C22 Buttweld Pipe Fittings such as elbows, tees, reducers, caps and stub ends for chemical processing, pollution control, pharmaceutical, marine and other critical services where standard stainless steels and duplex grades can be unreliable.

Buyers choose Petrofit when corrosion risk is high and documentation must be inspection‑ready. Our focus is to deliver ASTM B366 UNS N06022 Buttweld Pipe Fittings with traceable heat numbers, consistent dimensional compliance and clear certification so EPC contractors, consultants and third‑party inspectors can approve material without delays.

Product Overview – Hastelloy C22 Buttweld Pipe Fittings

UNS N06022 (Hastelloy C‑22) is a nickel‑chromium‑molybdenum alloy with tungsten, designed for strong resistance to a wide range of aggressive chemical environments. In practical plant service, Hastelloy C22 Buttweld Pipe Fittings are selected when systems face chloride‑bearing media, oxidising environments, mixed chemical exposure, or process variability that makes corrosion behaviour unpredictable. Many engineers specify ASTM B366 UNS N06022 Buttweld Pipe Fittings to control the risk of pitting and crevice corrosion in equipment where failure would cause shutdowns, contamination, or safety concerns.

From a procurement standpoint, Hastelloy C‑22 is typically used where it provides the biggest return: the most corrosion‑sensitive circuits. Many projects use a "selective alloying" strategy, placing Hastelloy C22 Buttweld Pipe Fittings in the harshest zones while using other alloys elsewhere. It's common to evaluate alternatives such as ASTM B366 UNS N10276 Buttweld Pipe Fittings for very broad mixed‑media resistance and ASTM B366 UNS N06625 Buttweld Pipe Fittings where higher temperature strength is also a major driver.

Applications of Hastelloy C22 Buttweld Pipe Fittings

Hastelloy C22 Buttweld Pipe Fittings are used where chloride‑bearing and oxidising media can cause pitting, crevice corrosion, or stress‑corrosion cracking in stainless steels. Typical applications include chemical process lines, scrubbers and absorber systems, waste treatment circuits and units exposed to acidic condensates and mixed process chemicals. ASTM B366 UNS N06022 Buttweld Pipe Fittings are especially valuable in systems where process conditions can change during operating cycles, increasing the risk of unexpected corrosion damage if lower alloys are used.

Key Benefits of ASTM B366 UNS N06022 Buttweld Pipe Fittings

The key benefit of ASTM B366 UNS N06022 Buttweld Pipe Fittings is strong corrosion resistance in aggressive environments, with particular advantage against localised corrosion such as pitting and crevice attack. Hastelloy C22 Buttweld Pipe Fittings help reduce failure risk in chloride‑bearing and oxidising media and provide a stable material choice when process conditions are complex or variable. For procurement teams, selective use of Hastelloy C22 Buttweld Pipe Fittings in the highest‑risk circuits can improve lifecycle cost by reducing repairs, replacements and shutdown exposure, while allowing more economical materials elsewhere.

Industries We Serve

Petrofit supplies ASTM B366 UNS N06022 Buttweld Pipe Fittings and Hastelloy C22 Buttweld Pipe Fittings to industries where corrosion control directly impacts safety, uptime and product integrity. Chemical processing plants use C‑22 in aggressive circuits, reactors, scrubbers and transfer lines where chloride‑bearing and oxidising media can cause rapid damage to stainless steels. Pollution control systems rely on Hastelloy C22 Buttweld Pipe Fittings in scrubbers and absorber units where acidic condensates, chlorides and oxidising agents coexist.

Pharmaceutical and specialty chemical plants use ASTM B366 UNS N06022 Buttweld Pipe Fittings in circuits where material stability supports long‑term equipment reliability and reduces contamination risk. Offshore and marine projects may also specify C‑22 in selected chemical treatment and injection services where chlorides and chemical additives make corrosion behaviour difficult to predict.
