China Inflatable Rubber Balloon Rubber Culvert Balloon Pneumatic Inflatable Rubber Mandrel

Contact person: Grady WangWebsite:www.zqdcrubber.com1. DescriptionPneumatic inflatable rubber mandrel is usually called culvert rubber balloon. It is akind of cylinder bag that can expand, shrink, used to form concrete component of cavity. It is easy to be used, convenient and durable, is soft and can fold, curly, contraction when it is deflate, it have the enough strength to withstand the pressure of concrete when it is inflated, this is incomparable with any traditional template,Valve Parts it is used in reinforced concrete members, including stake roof, roof board column, beam, building, water conservancy project(shipyards slipway, dock) .Construction practice proves that inflatable rubber mandrel is simple, not only save materials. And has ashape characteristics, it could be round. Oval, rectangle, vaulted, trapezoidal pipeline.etc.Also you can make astraight hole, etc. can make abuilding structure light ,thin wall hollow .change the concrete performance have been used rigid characteristic template Insulation situation
