What is a Slip-On Flange
01 — WHAT IS SLIP ON FLANGE

What is a Slip-On Flange?

A Slip-On Flange is a widely used pipe flange designed to slide over the outside diameter of a pipe before being permanently secured using fillet welds on both the inside and outside. Its bore is slightly larger than the pipe, allowing easy alignment during installation and simplifying the welding process.

Unlike a Weld Neck Flange, a Slip-On Pipe Flange does not feature a long tapered hub. Instead, it provides a simple, cost-effective, and reliable connection for joining pipes, valves, pumps, fittings, and other piping equipment in industrial piping systems.

Owing to their easy installation, economical design, and dependable performance, Slip-On Flanges are widely used in low to medium pressure applications across industries including Oil & Gas, Petrochemical, Chemical Processing, Water Treatment, Power Generation, HVAC, Marine, and General Industrial Piping Systems.

Faster Fabrication

Simple design reduces welding time and fabrication effort.

Reliable Sealing

Double fillet welds provide dependable leak-resistant performance.

Easy Pipe Alignment

Larger bore allows smooth pipe fit-up during fabrication.

Widely Used

Preferred for low and medium pressure industrial piping systems.

02 — WHY CHOOSE

Why Slip-On Flanges
Are the Preferred Choice

In modern industrial piping systems, engineers select Slip-On Flanges because they offer an excellent balance of cost-effectiveness, easy installation, and reliable performance.

Their slip-over design allows faster pipe alignment, reduces fabrication time, and simplifies welding, making them an economical solution for low to medium pressure applications.

From Oil & Gas, Petrochemical, Chemical Processing, Water Treatment, Power Generation, and General Industrial Piping Systems, Slip-On Pipe Flanges continue to be widely used where economical installation, easy maintenance, and dependable sealing performance are essential.

03 — ENGINEERING DESIGN

Design & Construction Excellence

The Slip-On Pipe Flange is engineered for easy installation, accurate pipe alignment, and cost-effective performance in industrial piping systems. Its slightly oversized bore allows the Slip-On Flange to slide smoothly over the outside diameter of the pipe before welding, making fabrication faster and more efficient.

After positioning, the flange is secured using double fillet welds on both the inside and outside, providing excellent joint strength, dependable sealing, and reliable performance in low to moderate pressure piping applications. This practical design reduces fabrication time while maintaining long-term operational reliability.

Our Forged Slip-On Flanges are manufactured in accordance with internationally recognized standards including ASME B16.5, EN 1092-1, and DIN Standards. Each flange is produced through closed-die forging and precision CNC machining to ensure outstanding dimensional accuracy, mechanical strength, and a long service life.

Available with Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) facings, our Slip-On Pipe Flanges provide a practical, economical, and versatile connection solution for Oil &; Gas, Petrochemical, Chemical Processing, Power Generation, Water Treatment, Marine, and General Industrial Piping Systems.
