Casting lightening holes with inflatable rubber pipe mandrel

Product Description

The performance characteristics of ARD inflatable rubber mandrel

1- Design scientific and reasonable used inflatable rubber mandrel, or casting parts, finished product can meet the requirement of design, easy operation, save work, save time, save material.
2- Have good ageing resistance performance and long service life this product use synthetic rubber, natural rubber and strengthen layer vulcanize. Has very good resistance to bulge, flexibility and elasticity, so can satisfy all sorts of work in the conditions of use.
3- Widely applicable temperature , within the scope 10 °C ~ +90 °C of the material without change.
4- For building light-duty construction provides favorable conditions to stress hollow concrete component, due to the rubber mandrel, the weight than use stress solid component light 20%, so it can reducing the weight of the upper structure of building, can make the pile foundation short, increase span, make the construction become simple and safety.
5- Construction technology is simple, safe, health, use it only need a few simple tools, without special process. only put the mandrel into negative reinforcement cage, inflate air to achieve work pressure, then pouring the concrete. When the concrete freezing, put gas out mandrel , in thus complete the product component forming, and it not pollute the environment.

Standard specifications of ARD rubber mandrel:

1> Diameter (D) : From 0.3m to 2.2 m.

2>Effective Length (EL) : From 6m to24m.

3>Total Length (TL) : From 7m to28m.

4>Other specification also available upon customer’s request.
