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.
