Product Description

The Lap Joint flange is a movable flange piece, which is generally matched to the water supply and drainage accessories. When the factory leaves the factory, there is a flange at each end of the expansion joint. The purpose of using the Lap Joint flange is generally to save materials. Its structure is divided into two parts. One end of the pipe part is connected to the pipe, and the other end is made into a butt welding ring. The flange is made of low-grade material, and the pipe part is made of the same material as the pipe, so as to save material.

What is Loose Flange(Lap Joint Flange)?

The connection of loose flange (Lap Joint Flange) is actually achieved by welding.
The difference is this type flange not welded with pipe directly, it uses the auxiliary component(such as stub end) welded with the pipe instead, and then the auxiliary component and the gasket are compressed by a connecting bolt. And the flange(Loose Flange) itself does not connect with the medium.
Flat welding and butt welding both available.

Advantage

1. Saving total cost. When the pipe material is special and expensive, welding the same material of the flange is expensive. You can choose the loose flange. (Flange could be a different material, only need auxiliary component material is the same as pipe material).
2. This flange could be rotated to easily align the bolt holes, and it is easy to install on large diameter pipes.
3.Suitable for places where pipes need to be disassembled frequently for cleaning or inspection. Or if you want to align the flange bolt hole, it only needs to turn the flange without rotating the pipe.

Flange Types

Weld Neck

This flange is circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications
erosion inside the pipeline. The weld neck is therefore favoured in critical applications.

Slip-on
This flange is slipped over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications.

Blind
This flange is used to blank off pipelines, valves and pumps, it can also be used as an inspection cover. It is sometimes referred to as a blanking flange.

Socket Weld
This flange is counter bored to accept the pipe before being fillet welded. The bore of the pipe and flange are both the same therefore giving good flow characteristics.

Threaded
This flange is referred to as either threaded or screwed. It is used to connect other threaded components in low pressure, non-critical applications. No welding is required.

Lap Joint
These flanges are always used with either a stub end or taft which is butt welded to the pipe with the flange loose behind it. This means the stub end or taft always makes the face. The lap joint is favoured in low pressure applications because it is easily assembled and aligned. To reduce cost these flanges can be supplied without a hub and/or in treated, coated carbon steel.

Ring Type Joint
This is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flanges.
