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:
  • Radiography
  • Mass Spectrometer
  • Ultrasound
  • 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.
