Large Diameter Hot Dipped Plastic Coating Corrugated Steel Pipe

large Diameter Hot Dipped Plastic Coating Corrugated Steel Pipe is the newest product developed and made by our company. And at present, our company is the only manufacturer of this product domesticly. We have successfully applied national patents.

The based material of this pipe is steel and the interior and exterior surface sides are coated with Polyethelene or epoxy resin. It has the advantages of both plastic and steel corrugated pipes.

The advantages include high mechanical strength, anti-corrosion, long using life, easy installation, quick construction etc. It's very suitable for burried pipes and culverts instead of concrete pipes and box culvert. It's the national popularized and environmental friendly product.

Large Diameter Hot Dipped Plastic Coating Corrugated Steel Pipe is mainly suitable used for below:

Civic construction:Civic burried water(rain or sewage) drainage, Utility tunnel, Cable protection, Checking well, Tower crane cofferdam, Vertical pile shell etc.

Road and railway: Culvert, Passage, Bridge, Tunnel overhaul, makeshift road, Leakage well etc.

Coal mine: Minerals transfering pipe, Passages for workers and machines, Mine shaft, etc.

Public construction: Power plant flue pipes, granary, cement bin, Gasometer, Fermentor, Wind turbine corrugated steel sleeve pipe, etc.

Martial use: Military channel, Air defence channel, Exit channel.

Economical and technical advantages:
1. High strength: 1.5 to 3 times stronger than cement pipe.
2. Light in weight: only 1 / 15 ~ 1 / 5 of the cement pipe with the same diameter.
3. Long service life: service life is more than 100 years.
4. Low cost: when the span (diameter)≥1m, the bigger the span is, the greater the economic benefits will be.
5. Convenient in construction: no need large machineries, only a little hand works is required on site.
6. Good axial flexibility: suitable for the places where the foundation settlement is serious.
7. The construction period can be shortened in half, hence saving labor costs.
8. Help to improve the "faulting of slab ends" phenomenon of land-based structures at the junction with the embankment, and improve the driving comfort.
9. Environmental protection and low-carbon release: reduce or completely abandon using conventional materials such as cement, sand, gravel and timber, this is conductive to environmental protection and reduction of carbon emissions.
10. Easy maintenance: maintenance free in a considerable part of the environment, hence reducing the operation costs significantly
