Product Description

Nickel Alloy SO Flange Manufacturer and Supplier

Looking for a high-quality Nickel Alloy SO Flange that meets demanding industry standards? TSM Technology Co., Ltd. is your trusted global supplier. With 14 years of experience and a strict quality control system, we specialize in delivering reliable, corrosion-resistant SO flanges made from superior nickel alloys like MONEL 400 and INCONEL 600/625. Precision-engineered for aerospace, medical, energy, and chemical applications.

What Is a Nickel Alloy SO Flange?

Nickel Alloy SO (Slip-On) Flanges are widely used in high-stress, high-temperature environments. They are designed to slide over the pipe and are typically fillet welded on both sides. This structure makes them ideal for low-pressure and non-critical applications that demand excellent corrosion resistance and strength.
