Slip On So Flange - China

What is a slip-on flange?

Slip-on flanges, also known as ‘hubbed flanges’, have a hub with a very low profile.

This slip-on flange is usually connected to a pipe by one or two fillet welds (one outside the flange and one inside the flange), it is, however, possible to use only a single weld.

The connection is typically secured with two fillet welds—one on the outer and one on the inner side of the flange.

For less critical applications, a single external weld can suffice.

This welding method, however, does not create a full-penetration bond, which makes slip-on flanges the ideal choice for lower-pressure and lower-risk environments.

Their design makes them a common sight in utility lines for cooling water, firefighting, low-pressure compressed air, and process lines carrying substances like steam, oil, and gas.

A key design feature of a slip-on flange is its internal diameter, which is slightly larger than the pipe’s outer diameter, enabling the “slip-on” fit.

While their weld integrity is lower than that of a welding neck flange, they offer a significant advantage in tight spaces.

However, if a welding neck flange cannot be used due to space limitations, a slip-on flange may be a suitable alternative.

When you need a robust and dependable connection, quality is non-negotiable.

Our slip-on (SO) flanges are designed to slide over the pipe and be welded securely, creating a lasting seal.

Every flange we supply conforms to the rigorous ASME B16.5 and B16.47 standards, ensuring your system meets critical safety and operational requirements.

Key Features:

Material: High-quality steel that ensures durability and resistance to corrosion.

Sizes: Available in a range of sizes to fit different pipe diameters.

Custom sizes can also be created upon request.

Standards: Manufactured according to ASME B16.5 and B16.47 standards, guaranteeing quality and compatibility with various pipe fittings.

Ease of Installation: Slides easily over the pipe and secures with welding, providing a robust and reliable connection.

Applications: Ideal for use in lower pressure applications and suitable for industries such as petrochemical, oil & gas, water treatment, and more.

SO flanges are available in two primary designs, each engineered to solve specific challenges within a piping system: 1 - Standard (Raised Face) Slip-On Flanges

This is the most common type, featuring a “raised face” on the sealing surface.

This slightly elevated platform is crucial because it concentrates the bolt-tightening pressure onto the gasket, creating an exceptionally reliable seal.

This design is highly effective and recommended for low-pressure systems where preventing leaks is a top priority.

2 - Lap Joint Slip-On Flanges

The lap joint configuration consists of a flat-faced flange that works with a separate backing flange and a lap joint stub end.

After the stub end is welded to the pipe, the backing flange can slide and rotate freely.

This clever design offers unmatched flexibility, simplifying the alignment of bolt holes during installation or maintenance.

It’s the perfect solution for systems that require frequent dismantling or those that experience thermal expansion and contraction.
