DN2200 (88") double-flange dismantling joint with longitudinal adjustment. 300 LB flange rating, ideal for large-diameter pipelines, easy valve/pump installation & maintenance. Custom sizes available.

Product Introduction

Double flange dismantling joint is also called compensator, expansion joint.

It consists of main parts such as body, sealing ring, gland, expansion short pipe, etc.

It is a new product for connecting pumps, valves and other equipment with pipelines. They are connected by full bolts to make them a whole and have a certain displacement. In this way, they can be adjusted according to the on-site installation size during installation and maintenance. During work, the axial thrust can be applied to the entire pipeline. This not only improves work efficiency, but also plays a certain protective role for pumps, valves and other equipment.

Advantage

1. Simple and convenient installation, convenient valve installation, and can withstand the axial tension of the pipeline.

2. Metals and sealing rings are strictly selected according to performance and user requirements. The material is coated with high-strength anti-corrosion paint on the outside, and the connecting bolts of each part are made of high-strength carbon steel or stainless steel. Because there is a certain gap between the body and the telescopic tube, it has a certain axial and radial displacement.

3. It can effectively compensate and relieve the thrust of the pipeline and blind plate in the pipeline, and it is convenient for the installation, maintenance and replacement of water pumps and valves. It is the most ideal supporting product in the pipeline installation and operation industry.

Packing

Small-diameter dismantling joints (DN50-DN900) are wrapped with plastic film and then packed into fumigation-free wooden boxes;
large-diameter dismantling joints (DN1000-DN3000) are packaged according to the mode of transportation.

If transported by container, wrap it with plastic film, put it on a wooden pallet, and then load it into the container and secure it; if transported by bulk carrier, make a suitable iron frame according to the size.

FAQ

Q1: What is a dismantling joint used for?
A: It enables longitudinal adjustment to install or remove flanged equipment like valves and meters without dismantling the entire pipe run

Q2: What size range and materials are available?
A: This model supports DN2200 (88"); constructed from coated steel with options for stainless tie-rods. Additional sizes/materials can be customized.

Q3: How is the adjustment locked?

A: Tie-rods secure the flanges at the set length, ensuring the joint is locked in position.
