Product Description

Nickel Alloy WN Flange Manufacturer & Supplier

TSM Technology Co., Ltd. is a leading manufacturer and supplier of Nickel Alloy WN Flange, specializing in premium nickel-based materials. With over 14 years of global supply experience, we offer top-quality flanges made from Nickel 201, Monel K500, Inconel 718, and Hastelloy C276. Our products meet the highest standards for aerospace, medical, petrochemical, and semiconductor industries.

What is a Nickel Alloy WN Flange?

Nickel Alloy WN Flange, also known as a weld neck flange, is a high-performance flange designed with a long tapered hub for butt-welded connections. It ensures superior strength and stress distribution, making it ideal for high-pressure, high-temperature, and corrosive applications.

We supply a wide range of pressure classes from 150# to 2500#, and sizes from 1/2″ (15NB) up to 48″ (1200NB), following international standards such as ASTM B564, ASME SB564, ASME B16.5, and B16.47.
