What are Nickel Alloy Pipe Fittings?

Industries demanding excellent corrosion resistance and high-temperature service can benefit from these performance-oriented components. Nickel alloy pipe fittings usually contain manganese, copper, silicon, carbon, and sulfur.

Inconel is one of the most used nickel alloys, displaying good thermal conductivity and weldability. Clients in sectors like chemical processing, pharmaceuticals, and oil refineries often select a Nickel 201 tee for durable performance.

Buyers can order these fittings in different types adhering to the required specification for compliance, for example, an ASTM B366 UNS N02200 cap

How is the tensile strength of Nickel Alloy Pipe Fittings tested?

These fittings display a high tensile and yield strength, which makes them perfect for demanding environments. Nickel alloy fittings can show mechanical strength of 586 Mpa (with a yield of 241 Mpa).

The industry-standard approach for testing the tensile strength of a WNR 2.4066 pipe bend and alloy 20 reducer is by applying controlled tension to a sample until the failure point. The output gets recorded as a load versus elongation. It is a destructive approach generally conducted on universal testing machines.

The test can also verify associated parameters of a nickel elbow, like yield strength, ductility, and hardness. Since strength is crucial to guarantee safety, tensile testing usually gets included in the Mill Test Report.

How does the choice of coating affect the quality and performance of Nickel Alloy Pipe Fittings in corrosive environments?

These products are highly resistant to harsh chemicals, boasting a corrosion rate of less than 0.0025 mm per year. However, using a protective coating on UNS N02200 buttweld fittings is sensible in highly corrosive conditions like oil and gas plants.

The preferred coatings include epoxy, FBE (Fusion bonded epoxy), hot-dip galvanizing, and electro-polishing. A graphene coating (carbon-based nanomaterial) on nickel 200 pipe fittings can extend long-term resistance to atmospheric corrosion.

Buyers should consider the increased costs that coatings will entail. They require additional processing of a nickel alloy reducer and other piping components, raising lead times and prices. However, we recommend weighing this against the performance and operational life advantages, which are substantial.
