Trusted Slip On Flange Manufacturer – #1 in India

When it comes to high-pressure piping systems, choosing the right flange matters. And if you’re looking for something that’s both strong and easy to install, a slip on flange is a perfect fit. At Unifit Metalloys, we take pride in being one of the top slip on flange manufacturers in India, delivering quality with precision.

What is a Slip On Flange?

A slip on flange is a ring that slips over the pipe end. It’s then welded both inside and outside to provide strength and prevent leakage. Easy to align and affordable, it’s commonly used in low-pressure applications.

Slip On Weld Flange: How It Works

This type of flange is welded to the pipe using a fillet weld, both on the outside and the inside of the flange ring. This creates a leak-proof seal, making it ideal for air, water, steam, oil, and gas services.

Stainless Steel Slip On Flanges

Stainless steel slip on flanges are popular in chemical, food, and pharmaceutical industries due to their corrosion resistance. Available in grades like SS 304, 304L, 316, and 316L.

Carbon Steel Slip On Flanges

Known for durability and strength, carbon steel slip on flanges are widely used in refineries, power plants, and mechanical systems. They come in ASTM A105, A350, and other specifications.
