Large Diameter Thin Walled Prestressed Cylinder Concrete Pipe

BPCCP, with high technical content, have the pipe core thickness of 1/16 to 1/32 of the pipe diameter. . Pipe description: Analyzing from the aspect of various raw materials, steel bell and spigot, steel plate, steel wire are fairly constant. That factor improve the performance of concrete and make it rise from C40 to C60 or even higher. Then, adding steel fiber in the concrete to let high intensity steel fiber take the place of ordinary concrete core. It can meet the final service conditions without having to add too many steel wires to reduce the pipe thickness. BPCCP is the final innovative product that has got rid of the shortages of large diameter PCCP. The key technology and innovative point of BPCCP is the adoption of high intensity steel fiber concrete instead of ordinary concrete core to achieve the ultimate goal of the weight reduction. We do not have to make enlargement adjustment on the production processes, test methods and production equipment of the pre-existing PCCP product. Only a little tuning can make the mass production.

Pipe standard: Q/TWLG 03-2007

Pipe diameter: DN1800mm-DN4000mm

Working pressure: 0-1.0 MPa

Earth covering : 0~4m

Application area: In the areas whose bearing capacity of the basic soil body is lower than 100KPa or coastal areas, in special geological conditions that the soil horizon the pipe will be inbuilt has high water content or the ground bearing capacity is low, the applicability of PCCP with ordinary thickness will largely limited. BPCCP can meet the service requirements in those geological conditions and the application scope of PCCP is accordingly wider.

Pipe fitting introduction and connection type with other pipes: We can provide all kinds of BPCCP supporting fittings. Pipes usually used are short pipes, bends, reducing pipes, tees, wyes, crosses, bifurcations, adapters, wallpieces, plugs, closures, etc. Through conversion pieces or connecting pieces, BPCCP can connect to steel pipe, ductile iron pipe, jacking pipe and so on. It is easy to use.

Price superiority: BPCCP is at least 30% lighter than ordinary pccp, so the charges of haulage, loading and unloading installation, paving and building, et will treatly reduced. That can then reduce the cost of the whole project and achieve energy conservation and emission reduction.

BPCCP is patent product of our company with the patent number of 200720097185.8
