It has an excellent recovery of 95% (after compression upto 50% of original thickness), which makes it the most suitable product for the said usage. It is an exclusive product specially designed to be used as expansion joint filler in concrete, brick, block work and isolation joints. It is also rot free and has no bitumen. What are the features and advantages of filler board? Resilient â?? Our EJF boards delivers 95% compression recovery after deflection (compression), that it is the most important and excellent attribute for any expansion joint filler boards. Weathering Effect â?? Joint filler board is resilient and additionally absolutely does not distort under less load transfer from wet concrete. Closed cellular composition â?? Very low water absorption consequently non deteriorating and also resilient Bitumen free â?? Non-staining and easy to apply. Chemically Resistant â?? to almost all types of acids, alkalies and hydrocarbon group materials. Simple â?? Easy to handle, carry, load/unload, install. Load absorption is higher and transfers to the structures very little. What is the use of filler board? Expansion joints at airport runways and taxi tracks The next usage are in mall parking lots as well as structures Furthermore these are applied to Isolation Joints to infill sections In addition to water-proofing also used in concrete flooring. Water retaining as well as water eliminating structures Inter-connecting pathways between buildings Basements, flyovers as well as subways. These kind of boards used in concrete roads as well as toll plaza flooring. Bridges, verandas, abutments and pier hinge joints For more details please visit: https://www.kampun.com/expansion-joint-filler-boards-kampun-hd100-board/
Type: in-line pressure balanced expansion joint It is composed of two working bellows at both ends, a balance bellows in the middle, tie rods, end plates and other structural parts. It is mainly used to absorb axial displacement and balance the pressure and thrust of the bellows. bypass in-line pressure balanced expansion joint Composed of two identical bellows, end ring, head, outer tube and other structural parts, it is mainly used to absorb axial displacement and balance the pressure and thrust of the bellows. external pressurized in-line pressure balanced expansion joint It is composed of two working bellows bearing external pressure, a balance bellows bearing external pressure, and end pipes, connecting pipes, outer pipes, end ring components and other structural parts, which are mainly used to absorb axial displacement and balance the pressure and thrust of the bellows. Feature: 1.Simple to manufacture 2.Stable at high pressures 3.Absorbs small amounts of axial and lateral movement 4.Eliminates change in pressure 5.No main anchors required 6.Conserves space Application: Pressure balanced expansion joints are used with low pressure turbines, with condensers and also with pumps and other equipment, that may be susceptible to pressure loads
Description: Elbow pressure balanced expansion joint is composed of a working bellows or two working bellows connected by an intermediate pipe and a balanced bellows and elbow or tee, head, tie rod, end plate, spherical and tapered washer and other structures. It is mainly used to absorb the combined axial and lateral displacement and can balance the pressure and thrust of the bellows. Usually, the pipeline expansion joint is a constrained general-purpose type that can accept lateral movement. Because there is also axial deflection, pressure balanced elbows are usually required. Feature: Absorbs axial and lateral movements Eliminates main anchors Minimum guiding required Pressure forces remain in balance No volume change Balance-pressure thrust remains constant Application: Elbow pressure balanced expansion joints are used in pipelines with a change of direction. Elbow pressure balanced expansion joints are used with low pressure turbines, with condensers and also with pumps and other equipment, that may be susceptible to pressure loads.
1, Product Performance: Expansion joint rubber bellows consists of rubber ball, U-shaped loop coupling flange, the rubber ball contains inner rubber lining, outer rubber lining, reinforced lining, T-shaped or L-shaped strengthening ring. It is mainly used for the flange connection of valves and equipment for compensation for deformation and equipment protection. 2, Product Applications: Due to the expansion joint rubber bellows has good comprehensive performance, mainly used for lifting and conveying, raw water and sewage water of coal-fired power plants, cooling circulation water, condensed water slurry circulation, metallurgical industry, chemical industry chemical pipelines, cooling of the petrochemical industry, the length of the dilution and other industries flexible connection between the distance line. Because the rubber has high wear resistance, but also applies to all industries of granular and powdered and gas transport in low temperature. In addition, in order to guarantee the construction quality, designers and users warned, if the product is installed close to exit of a pump or at the corner of pipes, a caging devices against disjunction must be noted for installation. In general, if there is any hidden trouble in your operation, relevant operation conditions must be noted in your order, and you will get a satisfactory reply. 3, Product Advantages: Single sphere expansion joint rubber bellows has good elasticity and long service life, especially for some installation environment is harsh environment have a good ability to adapt. Installed on the pipeline can be achieved for pipeline axial, lateral and angular displacement compensation, guarantee the pipeline safe operation, so as to prolong the service life of pipelines.

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.
