I plant absorption of foreign advanced technology, with many years of production experience, advanced technology and the gross domestic same industry leading position ..
The SJBG series forming machine is mainly concrete prestressed HDPE plastic corrugated pipe indispensable equipment, mainly used for highway overpasses, viaducts, railway bridges and other concrete works, changing different molds to produce PP, PVC, EVA and other kinds of corrugated plastic pipe. complete production lines from the extruder, extrusion die, molding machine, cooling device, the auxiliary traction machine, sawing machine, reverse station components. forming machine mainly gearbox, upper and lower template, transmission molding templates, machine planes, air-cooled unit, composed around a mobile device, gear box using arc tooth worm gear Hardened reducer, template material is HT150 down through the hollow casting, forced air cooled template, templates made of 40Cr heat-treated surface hardness of HRC45 -52, frame made of high quality steel welding, reasonable structure, stable drive motor first with a frequency converter, so as to achieve a uniform variable speed. machine up and down, left and right, front and rear automatic adjustment.
It mainly features: compact structure, smooth operation, carrying capacity, forced air cooling, high output, long life and other characteristics.

| Comparison of plastic corrugated pipe and galvanized corrugated pipe performance |
| Performance | Corrugated plastic pipe | Galvanized corrugated pipe |
| Corrosion resistance | Polyethylene is the most common plastics chemical properties of a stable, portland cement and water each mutually inert, and do not react, never rust | Galvanized rust performance is good, but the zinc layer is easy and grout base words and precipitation of the reaction of hydrogen, the steel of prestressed concrete bonding strength and have an adverse effect |
| Durability | Cement wrapped sealed case aging time up to 50 years | Life in general in about 5 years |
| Minimum bending radius | 0.9-1.5 (about 10-15 times the diameter or length of the shaft) | Pipe diameter greater than 30-fold depending on the direction of flat tube bending axis or the minor axis greater than 30-fold |
| Partial load resistance | After loading does not leak, no worries of bending leakage | Pipe deformation can not be recovered after leaking loads |
| Concentrated load resistance | Pipe wall thickness of 1.5-2mm, into a single ring arrangement, stiffness, fear crushes, can not easily be punctured vibrators | Pipe wall thickness of 0.2mm-0.4mm, spiral arrangement, stiffness is relatively small, crush deformation, pouring concrete vibrators can not touch the bellows |
| Hydrostatic pressure tightness | No continuous extrusion pipe fracture, humidity, humidity 20, pressure 50kpa conditions, to maintain watertight 24h | The steel pipe is 0.2-0.4 fold bite, will not leak under pressure, there will penetrate the cement under pressure |
| Coefficient of friction | 0.14 | 0.25 |
| Insulating | Non-conductive, good insulation | Conductive |
| Bonding and concrete | Plastic itself superior to the adhesion of concrete and concrete bond metal, while higher corrugated plastic pipe, and concrete good mechanical occlusion | Due to the impact of the zinc layer is not good bond with concrete | Bonding performance in general, and should prevent corrosion, rust resistance decreased adhesion to concrete |
