Corrugation 125mm x 25mm
Nestable Corrugated Steel Pipe
Characteristic of galvanized steel helical spiral corrugated culvert
Specification
Pipe diameter: 300-2500mm
Length: 1-12m
Thickness: 1.6-3.2mm
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 spiral corrugated culvert is only 1/10~1/5 of same size concrete pipe, even can be carried by people without machine.
Install in shorter time
The spiral 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:
Nestable corrugated culvert pipe
The spiral pipe corrugated culvert 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, spiral pipe corrugated culvert 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
