Nickel, whether as an alloy or in its elemental form, has made significant contributions across various industries and continues to meet the growing demand for materials. Known for its flexibility, nickel alloys can be combined with most metals, making them ideal for a wide range of applications. It is widely used due to its remarkable corrosion and heat resistance, particularly in industries such as nuclear and energy power plants.
ARK Stainless Inc. supplies premium-grade Nickel Alloy Buttweld Fittings that are well-suited for both high and low-temperature applications. These fittings, including grades such as Nickel 200 and Nickel 201, are known for their excellent thermal and electrical conductivity, as well as outstanding resistance to oxidation and corrosion. The chemical composition of these alloys includes elements like carbon, manganese, silicon, sulfur, copper, and ferrous iron, contributing to their high strength and stability. Our Nickel Alloy buttweld fittings are manufactured according to international standards, including ASTM B366 / ASME SB366, ensuring reliable performance across various industrial applications.

Different types of Nickel 200/201 Buttweld Fittings are categorized based on their shapes and functions. For example, tees are used to divide or combine process flows, while elbows are installed to change the direction of the pipe, typically at 45 to 90 degrees. Other types include crosses, reducers, caps, stub ends, unions, couplings, and threaded pipe fittings. Each of these fittings plays a crucial role in ensuring the efficient operation of a piping system.
Nickel 200/201 Buttweld Fittings are packed either according to standard practices or based on the customer's specific requirements. Before packing, these fittings undergo a series of rigorous tests, including PMI tests, chemical and mechanical analysis, 100% raw material authenticity checks, third-party inspection, and radiography tests, ensuring that only high-quality fittings reach the customers.
