Hastelloy Pipe Fittings

Hastelloy Pipe Fittings Specification

What are the different types of Hastelloy pipe fittings? Which applications are they commonly used in?

This exceptional corrosion- and heat-resistant material is a fixture in industries like oil and gas, chemical processing, marine sectors, and petrochemicals. Hastelloy pipe fittings boast an impressive blend of nickel, molybdenum, chromium, and tungsten (for stabilization). Not only can they resist uniform corrosive attack, but they also avoid stress-corrosion cracking and display top-of-the-rung weldability.

Buyers can order these performance-heavy fittings per specific needs, like Hastelloy elbow, bends, tees, caps, and stub ends. They are available in different grades based on the composition, like C22 and C276. Note that the main categories are types B, C, G, X, and N.

The standard hardness (40 HRC) and durability of a Hastelloy reducer make it attractive for several sectors, including agriculture, food processing, and instrumentation.

What are the standard testing procedures for Hastelloy pipe fittings?

Since alloy UNS N06022 buttweld fittings often operate in critical sectors like nuclear reactors and sulfonating systems, intensive testing is mandatory. The typical procedures for an alloy pipe cap include manipulative and non-destructive (NDT) techniques.

Most manufacturers integrate tests for hardness, pitting corrosion, flaring, and flattening in their quality control systems. NDT approaches for a Hastelloy reducing tee span radiography, positive material identification (PMI), ultrasonic examination, and magnetic particle inspection.

What are the performance characteristics of Hastelloy pipe fittings at sub-zero temperatures and high pressures?

These fittings showcase highly beneficial properties, from mechanical strength to high ductility. But the best part is that a UNS N06022 ASME SB 366 tee retains its characteristics under a wide temperature and pressure range. It performs dependably at sub-zero temperatures and can handle up to 1800°F or 982°C.

Pressures to 10,000 psi are manageable for DIN 2.4602 return bends. This material often gets picked for high-pressure applications like reactors. High tensile strength (690 to 783 MPa) complements its resilience amid abrasives like oxidizing agents, chlorides, and nitrates. In other advantages, an ASTM B366 UNS N06022 stub end is also not too challenging to form and shape.
