Helical corrugated culvert pipe machine is the machine special for producing helcor corrugated metal culvert, it is with a high capacity, because it is a difference process of producing helical corrugated metal culvert, it does not like producing the assembled or integral corrugated steel culvert pipe, no need more process on difference machines, only one machine is enough. The difference between the helical corrugated metal pipe to other steel culvert is its corrugation is in spiral, not straight, and its seam is locked by U shape connection, it no need bolts or flange.
Helical corrugated steel culvert machine working process
This machine is simple process on producing, there is a feeding unit for this machine, we put the steel belt roll on the feeding units, then it will feeding the belt in to the rolling corrugation units, after forming corrugations, it will lock the edge of the adjoining steel belts, this is the connection seam of the helical corrugated metal culvert. Finally, the machine will cut the culvert in the length as per our set.
Now, this machine has two types, one is big machine, it can only put in workshop, after installation, it is difficult to move. Another type is portable type, this machine can put on truck and take to the construction site to producing the helical corrugated metal pipe, then we can save big cost on delivery, because the helical corrugated pipe is disassembled, then it will take big cost on transportation, by this machine, we can avoid this cost.
Difference corrugation on helical corrugated metal pipe machine
Normally, the helical corrugated culvert is not in big diameter, so it no need big size corrugation, only small or middle corrugation can meet its design request, like corrugation 68X13mm, 75X25mm and 125X25mm. So if you want to produce all of these corrugation, you need 3 sets of mould, each mould for difference corrugation size./p>
When you want to produce difference corrugation, you have to remove the mould firstly, and then install the mould which you need, it will take a little time, but not long time.
The unit for rolling corrugation on the end of the helical corrugated
Because this corrugated pipe with a spiral corrugation, then it is a problem when we connection sections of helical corrugated steel culvert. But the coupler for difference sections connection with a straight corrugation, Then we need this machine to rolling the corrugation which is on the both ends of the culvert to be straight, after rolling the corrugation, it can match to the coupler’s corrugation, then it can be connected.
