Hongfa centrifugal concrete pipe making machine in Ethiopia

HF Pipe line Making Machinery is the ideal equipment to manufacture cement pipe. Reasonable design, reliable and simple operation, accord with state standard GB11836-89. The machine can be produced different sizes of tubular products such as connection tubes, small tubes and large tubes of inner diameter of 1200-1650 mm by using sand, gravel, stone chips, fly ash and slag mixed with appropriate amount of cement. The tubular products made by this machine has the following advantages: average wall thickness, smooth inner and outer wall, good impermeability, high compressive strength, low cost, firm and reliable tie-in, convenient construction, high efficiency and release the mold immediately to maintenance, etc.. The tubular products are widely used in agricultural irrigation, urban water supply and drainage.

HF series concrete pipe making machine has different types models:
HF800x2000, HF1200x2000, HF1600x2000 and XG2000x2000.

1) Flat Joint

Flat pipe is an joint form of cement pipe earlier, which is easy manufacture, high in production efficiency and low in manufacturing cost; the interface sealing adopts steel mesh concrete rag tape is a rigid connection, but its sealing effect and seismic performance are poor. If the foundation displacement causes the interface to be opened, the sewage will pollute the underground soil, causing great social and environmental inconvenience, so this interface is used less.

2)socket joint

The socket type interface adopts rubber ring seal to stop water, which is flexible connection. The interface insertion depth is 80-100mm, and the interface has a relative rotation angle of 1.5°. The cement pipe of this interface has good seismic performance. The pipe base is made of sandstone foundation or concrete foundation. high speed in installation. However, large-diameter cement pipes are not suitable for socket-type interfaces because large-mouth cement pipes produce circumferential cracks.

3)Flexible rabbet joint

The flexible rabbet joint form is mainly suitable for cement pipes with a diameter of ≥d1200. The interface form is also a flexible connection. The interface has the advantages of a socket type and is more prominent than the socket type, but it also has a remarkable feature that the socket type is not suitable for the large diameter pipe.. The depth of the socket pipe joint is not easy to control, and it is not easy to be dense when backfilling. The stress at the transition of the pipe socket is concentrated. In serious cases, the pipe body will have circumferential cracks, which will affect the service life of the pipe. The pipe body of the flexible joint pipe has good contact with the foundation. It is evenly loaded when subjected to load force, so it is safer to use; the outer wall of the socket of the socket tube is a sloped surface, so it is difficult to control the leakage when building the inspection well, so the flexible rabbet tube will be improved a lot; The rabbet tube can also be used as a top tube.
