patent product of our company. It is a new kind of pipe with characteristics of sealing well at the joint, high shock resistance
Pipe description: Steel bell and spigot prestressed concrete pipe (refer to SPCP), is a kind of compound pipe. The producing process includes wrapping prestressed wires around the concrete core, then spraying cement mortar. The joint is steel bell and spigot. Bell & spigot and sliding rubber gasket with each other to form flexible joint with excellent sealing quality. SPCP is a new kind of pipe with characteristics of sealing well at the joint, high shock resistance, convenient and fast when being installed, good antiseptic property and so on.Pipe standards: Q/TWLG 01-2003
Pipe diameter: DN500mm-DN4000mm
Working pressure: 0-1.0 MPa
Earth covering: 0~10m
Application area: SPCP can be used as main pipe in urban water supply and drainage, industrial water-transmission line, farm irrigation, pipe network in factory, supply pipes in power station, water cooling circulation system, inverted siphon, pressure tunnel pipeline, deep earth covering culvert and so on.
Pipe fitting and connection with other pipes: There are commonly used short pipes, bends, reducing pipes, tees, wyes, crosses, bifurcations, adapters, wallpieces, plugs, closures, etc. Through conversion parts or connecting parts, SPCP can connect to steel pipe, ductile iron casting pipe, jacking pipe and so on. It is easy to use.
Price superiority: SPCP can be installed fast (twice quicker than other kinds of concrete pipes installation rate); the engineering time will reduce, and then the labor cost, steel pile rent, support material rent and rainfall cost will accordingly go down. In addition, SPCP wear well and the operation and maintenance cost of it is low, so it usually can work at least 50 to 60 years or even 100 years. The service time of other kinds of concrete pipes is only about 20 years. Therefore, SPCP does not only have a low cost on composite expense of one time installation, it also has extremely good long term social comprehensive efficiency.
SPCP is patent product of our company with the patent number of 200620027067.5.
