well-organized business network that has its presence in many foreign
lands. Because of this network, we are today able to time and
efficiently distribute the products in Indian as well as foreign
markets, such as Greece, Germany and Singapore.
Research & Development Facilities
Testing Facilities : Our professionals are continually coming up
with new methods of designing and developing bellows technology. They
can perform all types of non-destructive testing, for instance:
- Mass Spectrometer
- Magnetic Particle
- Hydrostatic and Liquid Penetrant Inspection
As per the clients request, we can also perform cycle testing,
pneumatic testing, spring rate testing, impact testing,helium leak
detection and positive material identification (PMI). The design,
quality control and manufacturing process are in line with the codes and
standards, such as EJMA, ASME Section VIII and IX, ANSI B31.1, B31.3
About Installation of Bellows
It is a fact that bellow is not a hardware component that can
take up weights and misalignments due to improperly designed piping
system. The bellows must be install following an instruction that is
according to the recommendations of EJMA.
Metal Bellows Expansion Joints can absorb a particular amount of
movement as these can flex their thin-gauge convolutions. Therefore,
proper and careful installation is the key, as the incorrect
installation can cause reduced cycle life and the pressure capacity of
the expansion joints. It will further cause early failure of the bellows
element or can damage the piping system.
The most common installation errors can be avoided by following
these recommendations. If the client is uncertain about the installation
process, he must contact the manufacturer/piping design engineer for
clarification before continuing the Expansion Joint installation
process. Besides following the instructions of a pipe design engineers,
the piping system must haveproper supports hangers, etc.
