الوصف

PNEUMATIC TUBULAR FORM
Pneumatic tubular form is used for making concrete pre-casting formwork projects in culvert bridge construction.
 
Material:
Pneumatic tubular form is made from natural rubber and fabric. In general, it is formed by three layers(1+2=2layers of rubber and 1 layer fabric): inner layer is high strength synthetic polymer fabric withstanding the force from concrete and air pressure. Outer layer is vulcanized rubber. Rubber hardness is about 65Shore A to keep its excellent features, such as soft, durable, wear-resistance.
If your concrete slab is thicker, it should be manufactured in 2layers of fabric and 3layers of rubber(2+3).
Standard specification
  1. diameter from 0.2m to 3m,(round)
  2. total length from 1m to 28m(round)
  3. other specifications are also available according to clients request.​
