An expansion joint is one of the polyethylene joints that is used for preventing deformation of the domestic wastewater system, which occurs due to expansion or contraction, or the building settlement or shakes due to an earthquake that causes the domestic wastewater leakage. This joint may increase the strength of the pipelines against elasticity, expansion, or contraction.
Pipelines under the buildings face many threats. These threats differ depending on the internal and external factors. Among the threats that the wastewater lines and water transfer pipes encounter, we may point to internal and external pressures, landslide and tension, contraction and expansion, pipe stretching, building leakage, and leaking. The expansion joints are produced in different sizes and materials. It is a type of connector and joint available in various sizes, made of high-quality polyethylene and using them in the pipelines, especially under the building, prevents the building leakage and neutralizes the forces resulting from the expansion and contraction. These pipes, by preventing their stretch, increase the longevity of the wastewater system and finally the building’s life. The appearance of the cylinder expansion joint is in a form where the upper mouth is a bit bigger than the lower opening. The existence of the waterproof loop at its top enables the installer to use the expansion joint where welding is not possible due to a small space.
Polyethylene expansion joint is available in the market in three forms: 1- short expansion joint, 2- long expansion joint, 3- interface expansion joint
Among the benefits and features of the polyethylene expansion joint include:
Easy and fast installation, appropriate price and high quality, supplying in valid brands, mechanical and chemical resistance
Pars Etesal Shargh Company produces and offers various types of expansion joint in sizes of 63 to 125 and completely standard from first-grade materials.
