HYGIENIC EXPANSION JOINT
SANICOMP™

The very first Stainless Steel Expansion Joint specially designed for aseptic applications. The Hygienic Expansion Joint SaniComp™ solves the well known problem with finding a solution that considers both absorption of movements in the pipeline, due to fluctuation of temperature, as well as it adheres to the strict demands for clean ability in aseptic industries. The bellow construction ensures that the Hygienic Expansion Joint SaniComp™ is both flexible and easy to clean by means of CIP and SIP.

HYGIENIC EXPANSION JOINT SANICOMP™

HYGIENIC EXPANSION JOINT SANICOMP™

TECHNICAL DESCRIPTION

APPLICATIONS

SaniComp™ is specially developed for sanitary and antiseptic industries; and used in primary and secondary pipelines as well as CIP/SIP systems:

  • Breweries
  • Food and dairy industry
  • Dairy industry
  • Medical industry
  • Cosmetic industry

MOVEMENTS

Because of its unique design SaniComp™ can absorb movements in more directions, as axial or lateral movements. At the same time it is cleanable. Therefore the Expansion Joint has many installation options, and hence more possible ways of absorbing the lengthwise expansion. Temperature fluctuations result in the pipe construction expanding in an axial direction. To absorb the movements SaniComp™ can be placed in the longitudinal direction of the pipeline. In that way the movements are absorbed axially in the Compensator. Axial movement is an expansion or contraction of the Expansion Joint. The axial expansions of the pipeline can also be absorbed laterally in SaniComp™, SaniComp™ is more flexible laterally than axially. To save space and to deliver better drainage SaniComp™ is mounted vertically. Lateral movement is absorbed in the expansion joint as a parallel displacement of the compensator. SaniComp™ can absorb twice as much lateral movement as it can axially. The best use of the Expansion Joints results from the installation to absorb lateral movement. It is however possible to install SaniComp™ horizontally, but the drainage is not optimum in that position. For that reason vertical installation is recommended.

CONSTRUCTION

The bellows are supplied with the chosen connecting ends. A cover protects the internal parts. The cover is “floating” mounted on O-rings and seals. To ensure that no dirt can accumulate between the bellows and cover, seal ring is mounted between the cover and the end. The cover can be equipped with drain plugs, which, if vented can serve as an indicator for leaks as a control in the daily inspection. The placement of these drain vents is optional, depending on where it is best suited in the SaniComp™ fitted pipe. SaniComp™ is available in two different design versions:

  • Sanicomp™ in stainless steel and with sealing’s made from POM/PTFE
  • SaniComp™ manufactured completely from stainless steel

SaniComp™ fulfils both demands for cleanliness and flexibility. This is due to the optimum depth of the convolutions of the bellow combined with a specific distance between these convolutions. With this construction, optimum turbulence between each convolution is achieved which cleans the convolutions. The bellow geometry and the cleaning ability of the expansion joint is tested and verified by the guidelines of EHEDG.

An ordinary steel bellow typically has a number of convolutions placed close to each other with a significant height, that absorbs predefined movements. An Expansion Joint installed in hygienic productions must fulfil a number of demands. The Compensator must be cleanable and for that reason residues from the process medium must not remain in the convolutions of the bellow after the cleaning of the pipeline. An ordinary bellow is therefore inappropriate in this environment as its convolutions are too deep to provide the required turbulence.

QUALITY & TESTS

Belman is known for high quality products and therefore our quality control is a fundamental part of our business. All processes during production designed by the Belman quality engineers, is strictly follow and implement according our procedures and instructions and carefully inspected by Belman quality inspectors. All checks and inspections are done according to the strict prevailing Belman quality control procedures which is part of the Belman ISO 9001 quality management system approved by DNV.

 

ITP & Test
Inspection test Plan generated by the quality management system makes sure that each step of manufacturing has the appropriate inspection points such as Hold and Witness points.

Based on manufacturing code, project specification, application, media, and eventual ship classification rules Belman performs a large variety of quality tests including destructive, non-destructive testing and proof testing. All tests can be witnessed by the 3rd part based on the customer and classification requirements.

  • Destructive test: such as life cycle test and burst test to validate the design, i.e., vessels and offshore platforms
  • Non-destructive test such as Visual testing, dye penetrant test, Radiography examination, Magnetic testing, ultrasonic testing, hardness testing and PMI for all applications
  • Proof tests: leak test with air, leak test with helium and former gas, hydrostatic pressure test for all application

FAQ
on HYGIENIC EXPANSION JOINT SANICOMP™

Why use Sanicomp - a hygienic Expansion Joint?

Does this sound familiar:
“We have previously used Expansion Joints, but they were impossible to keep clean. Why should we use Compensators again?” This assertion can be frequently heard. It is a fact that a process pipe exposed to temperature fluctuations will contract or expand due to thermal expansion. If it is not compensated for these movements will lead to damaged pipelines and pipe components, with costly downtime as a further consequence. It is possible to absorb limited movements in a loop Expansion Joint, but Belman offers a more effective solution: SaniComp™ An expansion joint which is specially developed for sanitary productions. The EHEDG-certification means that SaniComp™ is approved for installation in national and international
sanitary industries.

Is SaniComp really cleanable enough for aseptic industries?

Hygienic design and function SaniComp™ is characterised by a completely hygienic, patent-pending design. SaniComp™ is easy to clean and therefore especially suitable for hygienic production.

It’s not just our belief…
SaniComp™ has passed the cleaning test set independently by EHEDG. This test demonstrates, among other things, that SaniComp™ is easier to clean than a reference pipe with the same dimensions and under the same conditions.
The installed position of SaniComp™ whether horizontal or vertical has no influence on the cleaning result.

How do SaniComp™ fulfil the demands for cleanliness

SaniComp™ fulfils both demands for cleanliness and flexibility. This is due to the optimum depth of the convolutions of the bellow combined with a specific distance between these convolutions. With this construction, optimum turbulence between each convolution is achieved which cleans the convolutions. The bellow geometry and the cleaning ability of the Expansion Joint is tested and verified by the guidelines of EHEDG. Drawings of the bellow can be seen from the SaniComp brochure.

How to position and install SaniComp?

Because of its unique design SaniComp™ can absorb movements in more directions, as axial or lateral movements. At the same time it is cleanable. Therefore the Expansion Joint has many installation options, and hence more possible ways of absorbing the lengthwise expansion. Temperature fluctuations result in the pipe construction expanding in an axial direction. To absorb the movements SaniComp™ can be placed in the longitudinal direction of the pipeline.

The best use of the Expansion Joints results from the installation to absorb lateral movement. It is however possible to install SaniComp™ horizontally, but the
drainage is not optimum in that position. For that reason vertical installation is recommended.
