BEST-IN-CLASS FABRIC EXPANSION JOINTS & BELLOWS Belman’s intensive cooperation with competent and experienced manufacturers of Fabric Expansion Joints enables us to deliver operationally effective and cost effective flexible fabric solutions that offer easy installation, excellent movement absorption and is custom designed for the client’s ducts and pipelines. Fabric Expansion Joints offer superior flexing capabilities compared to other solutions and can be made from a variety of special woven fabrics coated or laminated with selected elastomers or fluoropolymers. Fabric Expansion Joints are used to insulate, to avoid mechanical loads and to protect against abrasion. They offer advantages for the pipe work designer as they can absorb movements simultaneously in several directions. Furthermore, they have almost no reactive forces and require little space. Fabric Expansion Joints are easy to customise to suit existing operating conditions and are easy to transport and install in piping and ducting systems. In comparison to Metallic Expansion Joints, Fabric Expansion Joints offer almost unlimited flexibility, giving the pipe work designer more options. Fabric Expansion Joints are installed in systems operating with low pressure and dry media. Design range within Fabric Expansion Joints Belman Fabric Expansion Joints can be designed within the following range: SiZES: All sizes and shapes PRESSURE: Up to +/-20.000 Pa (+/- 2000 mmWg) Special constructions are available on request TEMPERATURE: Up to 750°C, minimum temperature -35°C MATERIALS: Flexible parts: Glass fabric, Wool material, PTFE, Silicones, Wire mesh amongst others Connection ends & Hardware: As per client request. TESTS: Visual test, dimension check or as per client specifications CERTIFICATES: On request certificates for steel parts can be supplied. CUSTOMISED BY BELMAN FABRIC EXPANSION JOINTS Belman offers a wide range of Fabric Expansion Joints, available in various sizes, designs, and materials, ensuring a long service life in piping and ducting systems. GET THE PRODUCT BROCHURE Download GET THE CHECK LIST Download FABRIC EXPANSION JOINTS INSTALLED FABRIC EXPANSION JOINTS TECHNICAL DESCRIPTION APPLICATIONS As Fabric Expansion Joints are customized designs (either closed or as open fabric belt for joining on-site) with bellows designed to solve the movement absorption in the application as well as meet requirements made by the gap in the pipeline. Fabric Expansion Joints of single-layer design can safely absorb movements caused by thermal movements in pipelines and duct systems. Accordingly, it has the possibility to be designed to accommodate the misalignments on request. Fabric Expansion Joints are applicable for: Chemical industry Oil & Gas Power Plant Pulp & Paper Steel plants Process industry Flue Gas Systems Boilers & Stacks Many more MOVEMENTS Fabric Expansion Joints absorb large movements within short built-in lengths ( due to multi layer construction). Fabric Expansion Joints Absorb movements in multiple directions simultaneously (several planes). The movements that the Fabric Expansion Joints are capable of accepting can be singular or a combination of: Axial movement (compression and extension) Lateral movement Angular rotation Torsional rotation A significant difference between Fabric Expansion Joints and Metallic Expansion Joints or Rubber Expansion Joints is that Fabric Expansion Joint types can readily accept the torsion which is undesirable with Metallic- and Rubber Expansion Joints. Furthermore, in addition to absorbing movements in the system, Fabric Expansion Joints can also absorb vibrations and help to reduce or eliminate noise. CONNECTION ENDS & HARDWARE The Belman Fabric Expansion Joint type is delivered as a customised design (either closed or special requirements as open fabric belt for joining on-site) with Bellows designed to solve the movement absorption in the application as well as meet requirements made by the gap in the pipeline. The Belman Fabric Expansion Joints are supplied as standard as a stand-alone Fabric Expansion Joint (with parallel or vertical f ixing flange arrangement) that may be supplied with customised connection ends and including hardware, but not limited to: Complete units (flanged or with welding ends) With loose flanges With clamping bands Special transport fixtures Flowliners / inner sleeves Pre-setting construction INSTALLATION Belman always supplies complete Fabric Expansion Joint solutions for quick and simple installation into the duct or pipework. When necessary due to transport or installation considerations we can supply Fabric Expansion Joints in segments for later assembly at the jobsite. ADVANTAGES Reduced heat loss by low surface temperature Minimum reaction forces Excellent movement absorption and flexibility Noise reduction High chemical resistance Higher flow velocity Can accommodate misalignments and a large amount of lateral offset (special design may be required and needs to be specified at inquiry stage) Good vibration resistance depending on design and materials 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 are strictly followed and implemented according to our procedures and instructions and are 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 The 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. Destructive tests, such as life cycle test and burst test to validate the design, i.e., vessels and offshore platforms Non-destructive tests, such as visual testing, dye penetrant test, radiography examination, magnetic testing, ultrasonic testing, hardness testing and PMI for all applications Proof tests, such as leak test with air, leak test with helium and Formier Gas, hydrostatic pressure test for all application All tests can be witnessed by the 3rd part based on the customer and classification requirements.
