Expansion joint Expansion joint can also be called pipe expansion joint, compensator, expansion. Expansion joint is divided into: corrugated expansion joint, sleeve expansion joint, square natural compensation expansion joint and other major types, 1. Compensation for expansion deformation caused by heating of absorption pipeline in axial, lateral and angular directions. 2. Absorb equipment vibration to reduce the influence of equipment vibration on pipeline. 3. The amount of deformation of pipelines by absorbing earthquake and subsidence. Because of the heat expansion and cold contraction of the pipe, so for the pipe, it is necessary to produce the stress and push tension of the pipe wall; The stress on the wall of the pipe affects the strength of the pipe, and the push and pull force increases. The fixed bracket of the pipe should be made large to withstand the push and pull force generated by the pipe expansion. Therefore, the variable opening method compensated by the ductile iron pipe mechanical joint fittings is used to reduce the stress and thrust of the pipe wall. The expansion joint is mainly used to compensate the expansion deformation caused by the temperature change of the pipeline, and also to compensate the length of the pipeline due to the installation and adjustment. It is mainly divided into three structural forms: wholesale elbow expansion joint, bellows expansion joint and casing expansion joint.
FUSTAR Corrugated Pipe Co,.Ltd is one of the leading manufacturers of expansion joints and metallic bellows. We design and manufacture Universal(axial) Expansion Joints according to EJMA standard and optimization design. With over 10 years of experience in the design and manufacture of bellows expansion joint combined with our state of the art on-site facilities enables us to offer a wide range of bellows suitable for any application and design requirements. Flange Connection It is very common to apply any standard and shape flanges to any size expansion joints for simple installation and replacement. We can follow ANSI, DIN, JIS and GB standard of flanges on different pressure grade, pressure from 0-5.0Mpa and diameter from DN15-DN8000mm in all different material following customersâ?? requirements. Any other special shape flanges can also be customizable. Welded Connection It is also a simple and economical connection type in project pipelines. Any matched pipe can be welded together with the bellows applied to pipe system. Diameter can start from DN10mm to DN10000mm and material can be carbon steel and all stainless steel including AISI304, AISI321, AISI316, AISI316L, Features Absorbs small amounts of axial, lateral, and angular movements Deflect in any direction Most economical Must be guided Requires main and directional anchors Data of Expansion Joint The designed pressure for this expansion joint is 1.0Mpa(or 1.6Mpa,2.0Mpa,2.5Mpa, 4.0Mpa), which can be customized in case of special requirements. â?¢ Model: DN15-DN8000, â?¢ Pressure: 0.1Mpa-4.0Mpa â?¢ Connection: 1, Flange-connecting 2, Pipe-connecting â?¢ Axial Compensation: 18mm-400mm â?¢ Standardï¼?GB/T12777-2008 â?¢ Working Temperatureï¼?ï¼?196â??ï½?450â?? Application Our products are widely applied to industrial equipment manufacture and engineering pipe connection of aerospace, marine, petrochemical, refining, power plants, temperature control, information industry, heating, to effectively ensure the high safety performance of transporting the toxic, flammable and explosive media in the pressure pipeline, and to avoid the leak pollution causing the pollution of marine, sky, plants and other environment pollution. The product characteristics are thermostability, high pressure resisting, corrosion resisting, fatigue resisting, resistant to use.
The auto punch bellow forming machine is divided into several ranges: DN100-1200mm, DN100-1600mm, DN1500-5000, customized. Auto expansion joint machine adopts our patent technology of rotating salver and the cones retract system; FUGE bellow forming machines use Siemens PLC and German Balluff sensors and servo motors to be more precise; the punch bellow forming machine owns 3 working positions and can form 3 bellows at the same time. The mechanical expansion joint forming machine is powerful enough for multiple layers of bellow and different materials, such as SS, Inconel.
