Special type corrugated steel pipe in different shapes can meet customers' requirements
Our company can supply corrugated steel pipe available in different shapes. They refer to non-standard circular corrugated steel culvert pipe that buried under the road, railway and it is made by corrugated metal coils or corrugated steel pipe assembled of corrugated plate. The shapes can be oval, dustpan, horseshoe shape. They are widely used in highway, railway culverts, channels, bridges, temporary pavement, drainage channels and a variety of mine roadway retaining wall supporting projects.
Material of plate: SS400 or Q235 hot rolled steel plate
Thickness of the plate: 2.0-7.0mm
It can be divided into according to the assemble form.
According to the sectional shape of channel it is available in round, oval, arched, horseshoe shape, dustpan-shaped and pear shaped.
By the form of import and export: orthogonal, oblique, straight, oblique mouth
Filling height: 1.5-60m
Diameter of span: 0.5-12m
Section of pipe connection form is divided into: inner flange connection, flange joints, plate lap, and clamp connection.
Waveform parameters (wave pitch*wave depth): 150*25, 200*55, 150*50, 150*65, 300*110, and 400*180.
Anti-corrosion treatment: hot dip galvanizing antiseptic treatment of ≥ 63 μm, secondary corrosion is generally added asphalt coating
Years of use are for more than 100 years.
The selection process
- According to the diameter, height of filling culvert to select the waveform parameters.
- According to the filling height, special anti-corrosion requirements to choose steel plate thickness.
- According to the conditions of transport, installation environment to choose assembled form.
Application of arched corrugated steel pipe:
- Highway and railway: bridge, culvert, channel tunnel, culvert tunnel overhaul, temporary pavement, infiltration wells.
- Municipal construction: common channel, optical cable protection, drainage ditch, tower crane, vertical pile shell.
- Coal mine: mineral transporting pipeline, and mining machinery, shaft passage.
- Civil: power plant smoke pass, warehouse grain reserves, fermentation tank, and wind power.
- Military: military sidewalk, air defense channel and evacuation routes.
From home and abroad application situation, corrugated culvert pipe has a strong ability to adapt; has great advantages to replace the traditional method so the application prospect is very considerable.
