Rubber Culvert Balloon Inflatable Pipe Plug Pipeline Plugging Airbag¹

Product DescriptionProduct DescriptionRubber Inflated Culvert Balloon for Hollow Slabs    The rubber inflated culvert balloon, also known as the bridge inflatable core mold, is an expandable and contractible cylindrical bag made of rubber with a fiber-reinforced layer, featuring excellent tensile strength, elasticity, and air-tightness. It is primarily used to form cavities in concrete components.    When manufacturing hollow components, the inflatable core mold is placed in the middle of the component and is expanded by injecting compressed air. The inflated core mold can withstand the pressure of concrete, thus effectively replacing traditional wooden, bamboo, and steel molds. When in use, simply open the valve, and the airbag will deflate, making it easy to remove from the cavity.Cross-sectional shape of inflatable rubber airbagProduction ProcessThe production process of rubber inflated culvert balloon is divided into two types: cold bonding process and hot pressing vulcanization process.    *The cold bonding process involves first processing the raw materials into sheets (or purchasing finished rubber sheets), then cutting them into corresponding pieces according to the shape of the inflatable core mold, and finally adhering them together with adhesive to form the inflatable core mold.    *The hot-press vulcanization process involves directly vulcanizing natural rubber under heat and pressure, combined with anti-tear fabric, to form the specified shape of the inflatable core mold in a single molding process without any seams.Specificationitemindexthickness tolerance, mm3.2±2shore A65±5adhesive strengh N/25MM≥8tensile strength, mpa≥12elongation at break %≥350300% constant elongation,mpa6stretching deformation rate≤20%suitable temperature,oC-10-+80appearanceno crack, no bubble, impurity length≤3mm depth≤1.5mm and no more than one place each meterInstallationProduct DetailsPackaging & ShippingCompany Profile    Hengshui Jingtong Rubber Co., Ltd., located in Hebei Province's Hengshui City, is a professional manufacturer of engineering rubber products.
