Product Description

 Prestressed Corrugated Galvanized Stainless Steel Pipe Making Machine

Prestressing corrugated pipe machine is a equipment to produce metal bellows which are used for the pre-arranged holes in prestressing concrete.It makes galvanized or cold rolled steel strip (black belt) into double waveform,then undercut and swage into orrugated pipe.It is widely used in highway bridges, railway bridges, construction of water conservancy, electricity and other national major projects.

Process:
Raw material (steel trip)---purge tank---Conduction frame---contoured roll---Winding head---undercut---pipe formation---cutting

Prestressed corrugated pipe is mainly divided into metal corrugated pipe and plastic corrugated pipe.
Thickness of the steel trip:0.25-0.6mm

Internal Diameter φ 40,45,50mm55,  φ60mm  65,φ70mm  75,φ80mm 85, φ90mm,95mm,100mm

Features

1. The pitch is 78mm, the material is saved, and the rate is high.
2. Fast speed, stepless speed regulation motor.
3. Easy to operate and maintain.
4. Durable and long life.No overhaul within 2000000 meters.

      

1. As an industry benchmark, the following are our advantages
2.  Full automatic Siemens touch screen control system, winding and belt feeding, cutting and unloading, control sawing, automatic speed reduction, automatic cutting and automatic speed increase, automatic unloading, can be made into a shelf, the material can be automatically unloaded into the shelf, and the crane can be hoisted directly when it is full. If it is cut manually for half a minute, it will be cut once, which is especially labor-intensive

Our speed is about 20 meters per minute, 10000 meters in 8 hours, four wave design


corrugated pipe machine a kind of equipment for producing pre-stressed concrete reserved tunnel metal bellows makes the galvanized steel strip coil into four wave shape then undercuts and swages to apply the bellows, Which With high efficiency and Small volume, Easy operation and maintenance, convenient and speed adjustable. It is suitable for centralized use at construction sites and factories.

We use 78 steel strip, not 36 steel strip. It is light in weight and fast in speed. The four ripple design is easy to control and debug. It helps customers save about 1 ton of material every day. For example, a roll of steel strip weighs 350 kg and has an inner diameter of 500. We have infrared sensing device. If there is no steel strip, we will stop automatically. The workers can connect the steel strip with our electric welding machine, and the skilled workers will complete the operation within 10 minutes

For length cutting, we have a travel switch on the reversing table. For example, everything in 10 meters will be cut automatically in half a minute


Meter weight is light, which can save customers nearly 1 ton of material in a day. Taking 85mm weight per meter as an example, the customer used to design 765G before, but now our machine is 645g, saving 120g steel belt per meter

Taking 55mm as an example, the weight of the meter produced by our machine is 397G, which saves 100g. Considering all specifications, the average material saving is 12.5% per meter, and the production speed is 2.5 times faster. The time for changing the mold and discharging the pipe is about 20 minutes, the wave height below 95mm is more than 2.5mm, and the diameter above 100mm is 3mm
