Metal Expansion Joints from Unisource Manufacturing. Railway Expansion JointsUsually, expansion joints are not provided in the railways tracks, but if the track is laid on a bridge having expansion joint, providing a expansion joint in the track becomes mandatory to mitigate the expansion in base concrete structure.
Stainless steel bellows or special alloy material can be a single set of bellows or dual. Loops for even greater motions can be constructed upon request. Rubber joints can absorb greater movements when compared to similar length metal expansion joints. Concrete Metal Expansion Joints/ Ceiling Expansion Joint Cover for Construction - China Expansion Joint and Seismic Expansion Joint. They are used where concrete's proximity to pipes carrying high-temperature gasses, steam, or liquid could cause damage from temperature expansion, vibration, or movement. Below you will find links to company and product information for manufacturers and suppliers listed in theExpansion Control section of Sweets. CS provided a custom SSRW system filled with stone pavers around the building's perimeter.
Pipe alignment guides help to control the motion of pipe and expansion joints, insuring that the joint is subject only to the deflection for which it was designed. It is a chemical-resistant, ultraviolet stable, …. End fittings can be plate flange, forged flange, or weld ends. Standard bellows are constructed of single ply or multi-ply Type 304 stainless steel and are suitable for most chloride free applications such as steam, condensate, oil, and chilled water. Ideally used in retail shops, hotels, sports facilities and schools. EXPANSION JOINT SPECIFICATION DATA AND SIZE INFORMATION. Metal expansion joints concrete. Concrete expands and contracts with temperature changes and can also shift with ground movement or other forces. Some are installed prior to or during the pour, and others are installed after the concrete has set.
Metal Expansion Joints Concrete
Our 3-stage blasting & coating process. The aluminum cover is suitable for flat and pitched roofs. This places compression stress on the bricks and mortar, encouraging bulging or flaking. Alternatively, they are cut 1/4 of the way through the set-up slab using a lightweight dry-cut concrete saw or heavier wet-cut concrete saw. General Information on Pro-Key: - Construction Joints. Metal expansion joints for concrete knives. Flange materials - all of the above + P245gh, p265gh CARBON STEEL for the flanges|. For higher pressure applications, Unisource V-Loops can be constructed using double braided hose legs. Expansion joints will expand and contract due to thermal fluctuations, and move with other forces. The profile replaces the well-known sealant joint and other...
Available in standard corr height or high-corr. Proper joint spacing and depth are essential to effective control of random cracking. VERSION: FLAT AND ANGLE CHARACTERISTICS: Watertight floor expansion joint Designed for car parks, ramps, podiums… For joint gaps from 15 to 35 mm Waterproof floor expansion... Possible movement: 100 mm. They are not expansion cracks. Expansion joints are provided in slabs, pavements, buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures. ROOF JOINTS FOR MOVEMENTS < 375 MM The SRFL roof joint is movable in any direction and accommodates thermal and seismic movements. Standard spider guides are manufactured to accommodate specific amounts of movement and insulation. Expansion Joint in Concrete – Types and Characteristics. The two aluminium components slide one into the other, which takes up any movement due to expansion and contraction. See the HVAC section under Special Market Focus more more information and submittal on Unisource V-Loops. Inventory is sold and received continuously throughout the day; therefore, the quantity shown may not be available when you get to the store. In-line pressure balanced expansion joints are constructed for axial applications of straight runs of pipe that cannot provide main anchors to react the pressure thrust of the expansion joint. The material used to fill the gap needs to be flexible, durable, and resilient. See specification data and size information chart on page 2 for details.
Rectangular metallic bellows expansion joints are fabricated to absorb vibration and thermal movements in duct systems. A rubber expansion joint is a flexible connector to absorb noise, shock, vibration, physical and thermal energy. High resiliency with excellent recovery after compression. Inconel 600 and 625. China factory Jingtong rubber concrete road expansion joint. 5, or beveled weld ends||Used on all units||Carbon steel Sch Standard|. DECK-O-FOAM expansion joint filler is a flexible, lightweight, non-staining, polyethylene, closed-cell expansion joint filler. Metal expansion joints for concretedev. Industry Applications.

Our technical solutions can be adapted to any type of finish: expansion joints for concrete, expansion joints for resin, expansion joints for tiles and many others. Series EP joints also are frequently specified instead of slip joints that are also engineered for large movements because of several factors. The location of expansion joints depends on a huge number of factors, including purpose, location, and climate. Most residential basement floors are within a heated shell and often below frost level, and don't require expansion joints. Compatible with all hot- or cold-applied sealants. SPEED-E-JOINT offers an ideal solution…. Expansion joints are recommended every 75 to 150 feet depending on location and climate but may be closer together for some purposes, such as sidewalks. The coefficient of thermal expansion in concrete is 0. Used and aligned in floors, walls, and ceilings, plus at the perimeters and corners to permit independent movement of structural components.
Temperature can cause long stretches of concrete, like highway slabs, sidewalks, driveways, or outdoor malls, and patios to expand or contract anywhere from 1/2″ to 1" in all directions.
