Inflatable mandrel is a kind of expandable and shrinkable cylindrical bag,which is used to form the cavity of concrete member.When the hollow member is made,it is put into the middle and filled with compressed air.When the concrete solidifies and the compressed air is released from the bag,the mandrel can contract and be extracted from the cavity.It is simple to use,economical and durable,not inflatable soft shrinkage, arbitrary folding,crimping,inflatable expansion has enough strength to withstand the pressure of concrete, this is any traditional steel template incomparable.It is widely used in industrial and mining foundation, highway bridge,construction engineering,tunnel engineering,water conservancy engineering(dock, slipway,wharf).

Product Description
Inflatable culvert balloon
Product Introduction
Product Introduction
Product performance Features:
1.the design is scientific and reasonable:the application of rubber inflatable core mold,prefabricated or site pouring out of the finished components,can meet design requirements,and simple operation,save labor, save time,save material.
2.Good aging resistance and long service life:the product is vulcanized with synthetic rubber,natural rubber and reinforcing layer.After made.It has good tensile strength,elasticity and flexibility,so it can meet all kinds of working conditions to use.
3.Widely applicable temperature:within the range of-15°C~95C,the material does not change.
4.It provides favorable conditions for building site construction: prestressed hollow concrete members, due to the use of rubber core mold,Its weight is 20%lighter than that of non-prestressed solid members, so reducing the weight of building superstructure can shorten the pile foundation,Increased span,easy and safe site construction.
5.The construction process is simple,safe and hygienic:rubber core mold is used,only a few simple tools, no special work is required art.As long as the core mold into the steel cage,the air pressure to reach the working pressure,that is,pouring concrete,waiting for the beginning of concrete.When setting,the core die can be vented out to complete the forming of finished components without polluting the environment.
