Seamless nickel alloy pipes are used in chemical processing, oil and gas, power generation, marine, and pharmaceuticals. They handle corrosive environments and high temperatures well.
Nickel Alloy Seamless Pipe Manufacturer in China
We are Zhejiang Xintongda Special Steel (XTD), a reputable Nickel seamless pipe supplier and manufacturer in China. This pipe is a high-performance, weld-free tubular product made from pure nickel. We manufacture this pipe in compliance with the ASTM B161 standard. We provide the Nickel seamless pipe designed for the most demanding environments. Our pipe is defined by its manufacturing form, which creates a uniform structure characterised by the absence of welds. Unlike welded alternatives this pipe offers superior structural integrity and consistency throughout the material. We offer different grades of Nickel seamless pipes in many sizes, wall thicknesses and lengths to meet diverse industrial specifications. Our commitment to quality ensures that every Nickel alloy seamless pipe we deliver meets the highest international standards for performance and reliability. As a multiple international certified company, we maintain an annual supply capacity of 25,000 tons. We supply stock orders of this pipe in a week, while specialised production orders typically take 15 to 60 days.

What is Nickel Alloy Seamless Pipe?
A Nickel alloy seamless pipe is a solid cylindrical form produced without any longitudinal or circumferential seam. Technically, "seamless" refers to a product that is extruded and drawn from a solid billet rather than being formed from a flat plate and joined. While welded pipes rely on a filler or fusion at the joint, seamless nickel alloy pipe maintains a continuous metal grain. This method allows multiple nickel alloy pipes to be produced in seamless form to ensure maximum pressure resistance.
Manufacturing Process of Nickel Alloy Seamless Pipe
The manufacturing workflow of Nickel alloy seamless pipe begins by heating a solid round billet. This billet undergoes piercing to create a hollow shell. The cold-worked seamless pipe is refined through further drawing or rolling and finished with heat treatment to get the required mechanical properties.

Nickel Alloy Grades we Provide in Seamless Pipe
We provide these 2 Nickel alloy grades in seamless pipes:
01
Nickel 200 Seamless Pipe
Nickel 200 seamless pipe is made from a commercially pure wrought nickel. It provides excellent resistance to corrosive and alkaline environments. It is highly ductile and maintains its properties across a wide temperature range. It is used in chemical processing, caustic handling, and heat exchangers where reliable corrosion resistance is required.
02
Nickel 201 Seamless Pipe
Nickel 201 seamless pipe is the low-carbon version of Nickel 200. It is specifically designed for applications involving temperatures above 600°F. The lower carbon content prevents embrittlement during prolonged heat exposure. This makes it suitable for thermal processing, chemical industries, and equipment operating under elevated temperatures.
