Product Description

Product Description

Description of inflatable/pneumatic rubber formwork for concrete :

 

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.

Features of inflatable/pneumatic rubber formwork for concrete:

1.one strength cloth layer between two rubber layers, better tenslile strength, prevent explosion when you inflate, wear resistant.
2.Vulcanized production technology, not easy to crack.
3.More than 80 times reused servise life time.
4.Lighter weight, easy installation and transport.
5.Full set of accessaures, you can install directly when you got the goods.
6.factory manufacture, customized size and shapes.

Packaging & Shipping

Packaging:

1.Plastic Film Wrapping: The airbags are tightly wrapped in plastic film to protect them from water, dust, and abrasion during transit.
2.Palletization: Airbags are usually placed on pallets for ease of loading and stacking. Palletization also helps to protect the airbags from damage.
3.Securing: On the pallet, airbags may be secured with ropes, tapes, or other fastening materials to prevent movement during transportation.

Shipping:

1.Sea Freight Containers: Given the large size of pipeline blocking airbags, sea freight is a common method of transportation. Containers provide a secure and protective environment to prevent damage during long-distance shipping.
2.Container Types: Depending on the size and weight of the airbags, standard 20-foot or 40-foot containers may be used, or special-sized containers may be required based on the needs.
3.Securing Inside Containers: Inside the containers, airbags and pallets are properly secured to prevent movement or tipping during transit.
