We use galvanized steel, aluminized steel and galvanized steel coated with polymer to manufacture and supply round and dome-shaped corrugated pipes with diameters ranging from 6 inches to 144 inches.
We use galvanized steel, aluminized steel and galvanized steel coated with polymer to manufacture and supply round and dome-shaped corrugated pipes with diameters ranging from 6 inches to 144 inches. (In some places, a diameter of 192 inches is available. ) 012 spiral ribbed corrugated steel pipes are widely used in rainwater drainage pipes that require smooth inner pipes. Corrugated metal pipe(CMP Pipe) can be used in various configurations.
-Culvert
-bridge
-tunnel
-under pass
-Ecological crossover
-pedestrian tunnel
-hanger
-Shelter
-warehouse
-Ammunition shop
-Belt conveyor protection
-Ventilation duct
-As well as the reinforcement and reconstruction of existing structures.
As long as proper backfilling is performed, a multi-board structure can be used for each type of service load. Depending on the piping environment and service life, CMP pipe offers homeowners and designers a wide selection of manufacturing options.CMP pipe offers users a product with proven strength, a predictable 100-year service life and unmatched fire resistance.
With its wide range of available configurations, CMP pipe can be used in a variety of applications, such as:Culverts, storms, irrigation, agricultural drainage, pipes, fume hoods, power plant cooling lines, conveyor tunnels, utility pipes, infrastructure, culverts, sewers, service tunnels, recycling tunnels, rainwater retention/interception systems, rainwater pipes, small bridges Replacement, caisson and infrastructure, exposed trachea, sidewalks and animal passages, and material pipelines. Whether it's specialized fabrication, longer run times or demanding deadlines, CMP pipe is the most cost effective solution.
The steel used for corrugated steel pipes is produced in accordance with Chinese standards.
Minimum yield strength 235N/mm2 and 345N/mm2
Steel standards Q235 and Q345
Can also comply with EN10025
Steel standard S355JR, S235JR, S315MC
And other standard steels can be used according to customer requirements
The economic solution for the initial and life cycle took more than 100 years, using various corrugated and wall thickness steel and aluminum pipes up to 144 inches in diameter. These choices allow designers to economically match the best materials to site conditions. Variable, multiple diameters, layout configurations and materials, which are unmatched by the versatility and flexibility of corrugated metal pipe design. Corrugated pipe is the "preferred" material for most piping, culvert and drainage system applications.
The accessories manufactured by the excellent hydraulic system can provide an excellent hydraulic system by minimizing the energy loss during the transportation and installation of the lightweight structure
Various thicknesses and coatings can provide reliable alternative durable coating options to meet your needs, including various coatings such as galvanized (galvanized), type 2 aluminizing, and polymer film. Choose the appropriate coating according to the applicable environment. In this case, more than 100 years of retention can be achieved.
A solid structure that can withstand the replacement of highly active and deeply buried soil layers-high strength-the strength of the interaction of the steel-soil structure is basically almost unlimited
From the verifiable data of product quality to the verifiable data report of the production steel plant, 100% traceability can be achieved
The size, long size and design size of the assembly accessories are varied, allowing the filling height to exceed 100 feet, and the minimum coverage as low as 12 feet. Standard bellows have various sizes, shapes, specifications and corrugated profiles, which can help designers meet every hydraulic and structural condition of each site.
Obtain sustainable products by using the most recycled materials in the world
Corrugated metal pipe are available in many different material types to economically meet the environmental and applicable conditions that meet the installation requirements.
| Flexible structure | Plate thickness | Kinds of standard corrosion protection | Required average min value(um） |
| plates | ≧6mm | Hot zinc galvanizing | 85 |
| ≧3mm do < 6mm | Hot zinc galvanizing | 70 | |
| ≧1.5mm do < 3mm | Hot zinc galvanizing | 55 | |
| Bolts and nuts | - | Hot zinc galvanizing | 45 |
By covering each surface of the core with a high-grade aluminum alloy having a total thickness of 10% of the total thickness, the corrosion resistance can be further improved.
The pipe is made of 1 inch per square inch aluminum-coated steel coil.
A uniform coating is applied to the inside and outside of the pipeline to expand the replacement of CSP galvanizing.
Traditional galvanized CSP is produced from steel coils with two zinc coatings per square foot.
A 10 mil polymer film is pressed onto each surface of a galvanized steel coil to form a high-quality coating that is currently available. The protective film is strong
The minimum allowable depth of cover is the largest of:
For roads H=B/8+0.2(m) H=B/6(m) and not less than 0.6（m）
For railways H=B/4 and not less than 0.6(m)
There is a possibility to reduce depth of cover provided that suitable checking calculations will be made.
