The horizon of the company is extended by the combination of technology, competent team and their vision to lead.
Research and Development
In our business strategies, R&D activities are critical in
the development of business. Therefore, we work towards the development
of new products using technologies that have maximum growth potential
and predict industrial requirements in near future. Our research team
works with clients to provide them quality and innovative bellows. They
also find ways to improve the production process to promote better
utilization of resources. Our research specialists carry out the process
capacity analysis so that production process can be made more
efficient. The feasibility and efficiency of the new development in line
with the products and services are tested and then recommended to the
production or design department.
Wide Distribution Network
The determination and efforts have led to the development of a
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:
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.
Our Diligent Personnel
A highly talented team is created, the members of which work on
the commitment to design and develop qualitative and innovative bellows,
like axial bellows, hinged bellows,expansion bellows, expansion joint
bellows, double bellows, universal bellows, pressure balanced bellows,
in line pressure balanced bellows,etc., and other expansion joints. The
highly experienced and trained professionals carry out tasks in
conformation with the industry standards and specifications provided by
the customers. Our team includes following members:
Instrumentation control engineers
Research and development experts
All team members know how important is every stage of order
processing, from designing, engineering, quality control and packaging,
they make best use of resources to develop flexible hoses, bellows and
Designing and Engineering
The GMP standards are followed to comprehend the requirement to
international standardized designing and manufacturing techniques to
offer world-class bellows, like in line pressure balanced bellows,
expansion bellows, expansion joint bellows, etc., that stand apart from
others. As GMP practices have in-built Q-C methods, our team follows the
following methodologies while manufacturing the bellows to filter them
as per design and quality:
1) Identification of raw material by mechanical /chemical analysis by approved lab.
2) Radiography examination for welded parts if needed.
3) Pressure testing for testing leakages of parts and assembly.
4) Surface defects and weld integrity checks by liquid penetrant examination prior and post cold work.
5) Magnetic practice and ultrasonic test by third party agency.
6) Dimensional verification of parts and assembly.
7) Helium leak test by agency for bellows to cryogenic applications.
Seamless and hassle-free processes are followed to achieve
