Spiral corrugated pipes, as the best combination of strength and hydraulic efficiency, have a spiral pattern and locking seam construction, with Pipe diameters ranging from 300-2500mm (12" -100"). They are made of high quality galvanized corrugated sheets.
Spiral corrugated pipes, as the best combination of strength and hydraulic efficiency, have a spiral pattern and locking seam construction, with Pipe diameters ranging from 300-2500mm (12" -100"). They are made of high quality galvanized corrugated sheets. Also, spiral corrugated pipes can be connected by coupling systems or flanges depending on the project requirements. Normally, the cross section is round shape, corrugation is 68X13mm(2-2/3" × 1/2"), 75X25mm(3" × 1"), 125X25mm(5" × 1")
Pipe diameter: 300-2500mm
Length: 1-12m or customize
Thickness: 1.6-3.2mm
Corrugated culvert pipe is treatment by galvanized steel belt spiral seaming joint
The diameter is smaller than 1m, adopt corrugation 68X13mm, each section standard length is 6m. The diameter is bigger than 1m,adopt corrugation 125X25mm, each section standard length is 6m, and we can make different sizes according to customers' requirements. (Click to ask us!)
Corrugated culvert pipe connection by two or more pieces of clamping band or flange, inlay PE plate or sealant or rubber gasket, fasten by high strength bolts.
The steel plate is DX52D or SGHC, chemical and mechanical property should be accord with EN10327 or JIS G 3302-2010, steel plate size tolerance should be accord with GB/T-709
Clamping band and angle steel material is Q235, chemical and mechanical property should be accord with GB/T700
Clamping band or angle steel fastener need to adopt high strength bolts, nuts, the grand should be or higher than 8.8, its property should be accord with GB/T1231
Corrugated pipe adopt hot galvanized steel belt for forming, or after forming then hot galvanization treatment.
High strength: It with more than 1.5 times compression strength than the concrete pipe because of the corrugation structure.
Easy for transport: The weight of the corrugated steel pipe is only 1/10~1/5 of same size concrete pipe, even can be carried by people without machine.
Install in shorter time: The steel corrugated culvert is connect by clamping band or flange, and the length can be make according to the customers’ request, then easy to install, and can be installed in shorter time.
Long service life: The steel corrugated culvert pipe adopt 300-600g/m2 galvanization steel plate, normally its servise life is 50-100 years, if in the strong corrosion environment, painting asphalt on the in and out surface of the pipe, can enlong 20-50 years based on the normal service life.
Economic: The standard length is 6m, simple connection, shorter working time. Because it is light, easy for transport, with few foundation construction, lower fee on drain pipe. For example, we make comparison on steel corrugated culvert pipe and concrete pipe in diameter 800mm, corrugated steel culvert pipe is only need about 90% if concrete pipe fee, and it can save cost of forklift, crane, and other machines when the transport is not good.
The helical corrugated steel culvert pipe is used in municipal drainage,building outside drainage, farm drainage, industry drain system, also adopt in road and railway closed conduit or culvert, shell of vertical pile, rain water collection, etc
Drainage: domestic sewage, golf course drain, underground garage, factory drain, factory, airport water drain.
Culvert: drain-pipe under the road, higher cross drain-pipe, underground culvert of railway, small tunnel, closed conduit, small bridge.
Protection shell: underground communication cable, protection pipe for gas pipe， also can be adopted on construction site, and protection shed, etc
Industry: air conduit for gas in coal mine (negative pressure)
Farm: driven well wall for farm, invert siphon for irrigation, farm water drain.
Clean, smooth, and the zinc coating uniformity.
Connect pipe sections by clamping band, keep the pipe sections point at pipe sections, prevent separate, the bottom permeate or the filling back material permeate.
Classic clamping band system
When assemble the clamping band, lap over connect to each pipe section equally.
When fastening, the length and width of the part which over lap to the pipe have to can bearing the tightening force.
When assemble the clamp band, make sure the gap between two pipe section can be more than 25mm.
Clamp band width is 440mm
(remarks: normally, the clamp band is two pieces, for the big diameter, maybe need 3 pieces or more)
Angle steel adopt Q235 steel
Flange is made by bending the angle steel, manual electric-arc welding and drilling holes.
Corrugated pipe welding angle steel flange adopt manual electric-arc welding.
Corrugated pipe both end welding flange.
Inner diameter is 1m or smaller than 1m, the pipe flange edge is in length 56mm, thickness 6mm equal-sided angle steel, other flange adopt in edge length 70mm, thickness 6mm equal-sided angle steel, for the big pressure, adopte width 70mm, thickness 6mm flat steel.
After welding flange, the inside and outside welding seam painting Dacromet under normal temperature.
