Hastelloy Buttweld Fittings

Hastelloy Buttweld Fittings Manufacturer and Supplier in India

Hastelloy Buttweld Fittings

Buttweld fittings made from Hastelloy are expertly designed to perform under the strictest conditions, including corrosive and high temperature environments. These fittings are a must have in many sectors that require top tier performance like chemical processing, power generation, and marine engineering. Buttweld fittings made using Hastelloy boast exceptional mechanical strength, and they are relatively easy to weld; they stand the test of time in performance when you consider how long these fittings remain in service.

What are Hastelloy Fittings?

Hastelloy fittings are specialized pipe components made from alloys resistant to corrosion, like Hastelloy C22, C276, and other top notch grades. These fittings, which connect, divert, or control flow within a piping system, are well suited for applications where they're confronted with aggressive chemicals, high pressure, and elevated temperatures. The high nickel and molybdenum content of these alloys makes them far more resistant than stainless steels to stress corrosion cracking, pitting, and crevice corrosion.

Hastelloy Buttweld Fittings Types

We offer a complete selection of Hastelloy buttweld fittings tailored to the diverse needs of the industrial sectors:


All fittings are made to the exacting standards of ASTM SB 366, which ensures not only very good dimensional accuracy but also consistent performance and reliability.

Hastelloy Seamless Buttweld Pipe Fittings

Our buttweld pipe fittings made from Hastelloy are seamless. They are formed to higher tolerances than is common for products of this type. That gives them more precision, and there is less chance, if any, that they will leak. They are also much stronger than common pipe fittings. These factors make them ideal for any application where failure is not an option, particularly oil and gas, marine, and chemical processing environments. Even so, not all of our seamless buttweld pipe fittings made from Hastelloy are created equal. Some, for example, have 90 degree angles. Those types are called elbows.
