Helical Corrugated Steel Pipe

• 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.
  The steel corrugated culvert is connect by clamping band or flange, and the length can be make according to the customers’ request(standard pipe section length is 6m, and we an produce in the longest length of each section in 12m), 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.

Cross section shape and size of galvanized steel helical corrugated culvert pipe

Normally, the cross section is round shape, corrugation is 68X13mm, 125X25mm.

The helical corrugated steel culvert pipe is used in urban underground common trench, big water storage tank, 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.

Main Application

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.
