Prestressed plastic bamboo corrugated pipe equipment
By integrating sophisticated technology both home and abroad, our company has 15-year production experience, advanced equipment and superb technology, being currently the top manufacturer in China.
The production line is mainly used for such concrete projects as highway overpasses, viaducts and railway bridges, etc. By simply replacing different molds, PP, PVC and EVA as well as other different plastic corrugated pipes can be produced. A full bamboo prestressed plastic corrugated pipe equipment by extruders, extrusion die, molding machine, cutter, stacker or reel machine components. Molding machine is composed of gearbox, down and up template, frame, air-cooled unit, a mobile device, gearbox using arc tooth worm gear reducer hardened, the template material for the HT150 through the hollow casting, template forced air cooled, the template is made of 40Cr heat-treated surface hardness HRC45-52, welded steel frame with high-quality, reasonably stable structure, the drive motor first with frequency converter, so as to achieve a uniform variable speed. Machine up and down, left and right, front and rear automatic adjustment.
Main features of equipment: Compact structure, smooth operation, large carrying capacity, water cooling and forced-air cooling, high productivity, long service life, saving materials etc.

Performance comparison between plastic corrugated pipes and galvanized corrugated pipe |
|||
|
Performance |
Plastic corrugated pipes |
Galvanized corrugated pipe |
|
|
Corrosion-resistant |
Polyethylene has the most stable chemical properties among the general-purpose plastics, and it does not react with water or various Portland cements nor does it rust. |
Being galvanized, it has good anti-rust performance but it is easy for the galvanized layer to react with the alkaline cement slurry to generate hydrogen, and it does not affect the strength of pre-stressed steel or the bonding performance of concrete |
|
|
Durability |
The aging time reaches 50 years when sealed by cement |
The service life is generally around 5 years |
|
|
Minimum bending radius |
0.9-1.5 (about 10-15 times of inner diameter or major-minor axis) |
The round tube is larger than 30 times of the inner diameter, the flat tube is larger than 30 times of major or minor axis depending on the bending direction |
|
|
Partial load resistance |
No leak with load; no leak when bent |
When deformed, it cannot be restored, and water leak might occur with load |
|
|
Concentrated load resistance |
The pipe wall thickness is 1.5-2mm, with single-ring arrangement, tramping-resistant, not easy to be pierced by vibrator |
The pipe wall thickness is 0.2mm—0.4m, with spiral arrangement and relatively small rigidity, easy to be deformed with tramping, and the vibrator might damage the corrugated pipe at concrete casting |
|
|
Water pressure resistance and tightness |
The pipes is subject to no fracture under continuous extrusion, and maintains water tightness for 24h under temperature of 20 degree centigrade and pressure of 50kpa |
The pipe is bond with 0.2-0.4 steel bands, and it might leak even under no pressure, and concrete leak might occur under pressure |
|
|
Coefficient of friction |
0.14 |
0.25 |
|
|
Insulation |
Non-conductive, good insulation |
With electrical conductivity |
|
|
Bonding performance with concrete |
The bonding performance of plastics with concrete is superior than iron sheet, and the plastic corrugated pipes have more excellent engaging performance with the concrete because of the high corrugation |
Due to the influence of the galvanized layer, it does not have good bonding performance with the concrete |
It has ordinary bonding performance, easy to be corroded. The rust resistance performance reduces the concrete bonding performance |
