Expansion joints are an essential element that help you to safeguard your pipe or construction projects with ease and convenience. With the best expansion joints suppliers , it is easy to avoid the detrimental effects of the thermal movements.
However, expansion joint designs must be chosen after careful consideration and review. This is crucial keeping in mind that certain components can enhance the entire infrastructure better than the others.
Types of the expansion joints
There
are two types of expansion joints i.e. cylindrical and
rectangular.
Each type of the expansion joint has its fair share of benefits and shortcomings. Before zeroing down on any one, it is important to discuss your expectations with the top expansion joints manufacturers. If the same doesn't meet your desired requirements then choosing custom expansion joints is a good idea.
- Cylindrical
expansion joints
The
right expansion joints help to boost pipe infrastructure and ensure
effective movements that support flexibility. These consist of metal bellows,
rods and connectors at each end.
Cylindrical
expansion joints are also known as compensators that have a multi-ply
design needed to boost flexibility and stability during thermal expansion.
These carry a pressure tight design along with a welded interior and exterior cylinder.
- Rectangular
expansion joints
Rectangular
expansion joints are used frequently in industrial settings as these are used
in applications where there are less movements and flexibility.
These
are frequently used in boiler and HVAC systems as these assist in transporting
fumes to the chimney or steam from combine to condenser.
These also have convolutions that are suitable for handling low and medium pressures. Since the components do not restrict pressure thrust, it is best to use anchors to stabilise the system.
Why is it important to choose the best expansion joints?
Maintaining
the best pipe infrastructure is crucial as it helps to keep the system
functional and efficient. Further, understanding when to use cylindrical
version vs rectangular ones is important so that you get the desired results
for your selected project. This makes it easy to install or service a pipeline
effectively and efficiently.
Here are some of the other critical aspects of choosing the right expansion joints -
- Adequate installation
Proper
installation is critical to ensure adequate life of an expansion joint. Some of
the common errors that occurs in the process are -
- Installation
with a reversed flow direction
- Mechanical
damages caused by the work around the system
- Shipping devices are removed prematurely, etc.
Installation with a reversed flow direction becomes quite relevant when the flow liner is installed to prevent debris from accumulation.
- Improper support
The support in the piping system are crucial to ensure system stability. If adequate support is not present then choose tie rods, control units, etc.
- Over pressurized joints
Any
expansion joint that is under pressure than it was designed to allow will
surely fail sooner than expected.
Prevention of this failure can be avoided by understanding your requirements and ensuring effective purchase and management.
- Managing chemical exposure
Handling
the exposure of the joint to the chemicals like acids and chlorides can cause
problems inside the system. It is recommended to flush the entire setup with
water after using chlorides or similar harsh chemicals and control the triggers
of corrosion.
Similarly, it is crucial to follow the manufacturer's instructions to ensure effective working of the joints even after extended use. Common failures can be prevented using adequate maintenance and repairs.
Other
vital aspects to consider during the selection process -
Selecting
the best manufacturer is crucial to ensure effective results. Similarly,
communicating your requirements is important to attain effective outcomes.
While choosing these joints, focus on the following -
- Determine
the appropriate size of the pipe and desired expansion joints
- Internal
and external temperature conditions
- Application
and flexibility desired
- Pressure
of the transferring liquid
