Rubber expansion joint

Rubber elastomer joints are widely used to provide efficient ways to relieve movement stresses, reduce noise, isolate vibration, compensate for misalignment. With five engineers on our staff, two of whom have professional licenses, Mercer has successfully analyzed and designed a wide range of products for demanding applications. Our rubber expansion joints are specifically designed to reduce the need for maintenance, repair and manual assistance. The Tefspool expansion joint is a rubber spool with an integral PTFE liner, giving it the strength and pressure rating of a rubber expansion joint , and the chemical resistance of PTFE.

Hand-crafted rubber expansion joints available in single- and multiple-arch designs are custom-built to fit your application requirements. Our wide range of rubber expansion joints (types) in different rubber qualities and various reinforcements allow a tailor-made solution to be found for every application.

What is the common failure of rubber expansion joints? What are the different types of expansion joints? How do you install expansion joints in concrete? Get your big pipes and small pipes together, and reduce noise and vibration at the same time. Also called a tapered expansion joint , the Metraflex Concentric Rubber Reducer connects unequal size pipes that share a common centerline.

Expansion joints from Grainger help to allow the heat-induced give and take of structural materials that takes place during changes in weather. They can make it easier for a structure, such as a bridge, to expand and contract without shifting too much and causing damage or failure. General Rubber ’s Maxi- Joint brand represents our state-of-the-art line of rubber expansion joints , flexible connectors, rubber flanged hoses and accessories, as well as spray shields and penetration seals.

Expansion joints will not function and may very well over extend and fail unless these full thrust anchors are in place. Where a shut-off valve, reducing valve, check valve or any mechanical pipe fitting is installed in the expansion joint line, check with the manufacturer to be certain the pipe fitting can take the expansion joint thrust. OVERVIEW: The Flexicraft Ultraspool premium expansion joints are the most versatile rubber expansion joints available. The Ultraspool expansion joints come in diameters from to 12 and can be made with any elastomer material, and are stocked in EPDM, Neoprene, Butyl, and Nitrile rubber elastomers.

SPONGE RUBBER EXPANSION JOINT is produced to a uniform thickness and density from gray-colore top-quality, blown sponge rubber. It is easily compressed and has a recovery of or more of the original thickness. Expansion Joints are used as a mechanism to prevent expansion from thermal and vibration energy. ERV expansion joints from Elaflex are moulded single sphere type rubber bellows with swiveling metal flanges.

An expansion joint or movement joint is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials, and vibration, or to allow movement due to ground settlement or seismic activity. Flexi-Spool” expansion joints are a spool-type, hand-wrapped expansion joint with several construction features that provide advantages over standard expansion joints. The transmission of vibration is reduced and they protect equipment from these adverse effects. Rubber expansion joints isolate or reduce vibration caused by equipment.

Dampen Sound Transmission. Reinforced with support lin-ers (casing) and a barrelshaped bellows, axial, lateral and angular movements can be implemented even with small sizes. This petroleum free product is environmentally friendly, top of the line in quality, and made here in the U. Find quality concrete expansion joints online or in store.
