Hastelloy C276 Pipe Fittings

Hastelloy C276 pipe fittings specifications

What are the key properties and benefits of Hastelloy C276 Pipe Fittings?

The premier characteristic of these sought-after piping components is inimitable tolerance for high temperatures and corrosive agents. Hastelloy C276 pipe fittings have a luxuriant chemical composition: nickel and chromium with molybdenum and tungsten.

A DIN 2.4819 stub end works mainly in chemical processing, marine engineering, offshore refineries, and flue gas desulfurisation systems.

These fittings can withstand temperatures up to 1900°F and are generally hardenable through cold working. A Hastelloy C276 elbow also displays good machinability.

What are the industry standards for Hastelloy C276 Pipe Fittings? How do they impact quality and performance?

The specification covering these fittings is ASME SB366, which covers nickel-based alloys. An alloy C276 pipe bend can operate in varied pressures up to Class 2500. The industry-standard sizing for Hastelloy C276 fittings is ½ to 48 inches. However, many manufacturers can supply customised sizes for specific needs.

When acquiring these products, buyers should note that some vendors refer to Hastelloy C276 seamless fittings as Nickel Alloy C-276. Selecting high-quality products from trusted suppliers will directly improve application performance and safety. Following tight tolerances and adhering to quality-control guidelines help a alloy C276 reducer deliver a longer operational life with fewer defects.

How do you select the correct type of Hastelloy C276 Pipe Fittings for a specific application?

Since an alloy C276 buttweld pipe elbow can be pricier than many alternatives, clients should ensure compliance with the application needs.

A core consideration is your need for corrosion resistance. An C276 tee does not undergo grain boundary precipitation and withstands even hypochlorite and wet chloride gas.

Here are other guidelines for selecting the appropriate pipe fitting:

  • Specific piping solution: Do you need elbows, tees, reducers, or end caps
  • Compatibility with the size of valve and pipe: Assess the nominal diameter and the available threading
  • The media getting transported and its temperature (Note that the chromium content of a Hastelloy C-276 end cap is insufficient for highly oxidizing substances like concentrated nitric acid.)
  • Ease of maintenance
  • Service duration desired
