  Cause of damaged and worn of expansion joint in the factory
In general, expansion joint will be originally installed into the blower or system by designers
or producers before transferring the machines and equipments to users or factories.
Working life of most expansion joint by average are between 5-12 years, but it also
depends on types of machine and kinds of industry they’re implemented.
Some flexible or expansion joints – include bellow joints – can be used as long as the users
expected or even longer; it because of appropriately selected raw materials to fabricate
them by system providers (designer or engineer) that have long and hands-on experience to
handling the system components i.e. maximum temperature, working temperature,
safety controlling, limitation of components and so forth. All these factors encourage usability
and durability of installed expansion joint.
After years, most of expansion joint that has been heavily used is warn and useless; it’s time
to find a new one as its replacement. In this stage, problem will not be encountered with if the
users can find new expansion joint made with the same materials or equivalent one; otherwise,
they will waste production time, installing and removing of defective replacements. Of course,
it’s not wise to purchase a poor quality of expansion joint at the cheap price to eventually
damage your runtime production.
Cause to run out your lifetime expansion joint:
1. Unskillful staff or users that wrongly controlling or handling heating temperature of
machine and blower
2. Disregards or damaged machine and blower that are carelessly for preventive maintenance
3. Unbalanced supporting or stands of the machine and blower
4. Inappropriate raw materials for fabricating expansion joint
5. Incautiously install or uninstall of the expansion joint by subcontractors or manpower
These major cause can be harmful for expansion joint and other flexible joints in the
production, and you can see that most of them happened by errors of users instead
of system or equipments you might think before. Consequently, wise selection of
expansion joint makers can also be avoided these headache problem in your factory
and production line.
