Product Description

Metal Pipe Corrugated Duct Making Machine 
Post Tension Duct Forming Machine 
corrugated round Steel Metal Pipe Galvanized Metal Duct Making Machine

Qingdao Cuishi Machinery Co., Ltd. specializes in making full-automatic metal bellows machines. On average, one machine is delivered every day, which is in short supply and has been highly praised by market customers
The machine is widely used in highway bridges and is highly praised by customers in Yunnan, Guizhou, Sichuan, Henan and Hebei

   Prestressed corrugated metal bellow has been widely used in modern construction by developed countries such as Britain, France, the United States and Japan. It is light, thin-walled, rigid, non-breakable and non-leaking, because of the obvious concave and convex four waves on the exterior of the pipe body, the steel pipe joints are tightly embossed, firm and non-disconnected, and the contact grip with concrete is extremely strong after casting on site, and the concrete is formed into a complete whole, enhancing the seismic performance of the structure. It has excellent function, compared with the general solid flat slab, it has light self-weight, large span, small deflection, no column cap, good safety, low comprehensive cost, thus improving the building headroom, increasing the use and sales area, compared with the existing domestic ordinary beam-slab structure, solid beamless slab, unbonded prestressed concrete floor slab, saving steel 12.5%, saving concrete volume 30-50%%, saving vertical water, electricity, air conditioning, It also has the effect of sound insulation and heat insulation, which brings considerable economic benefits to the owner.

         Prestressed corrugated metal bellow is mainly used in highway bridges, railroad bridges, construction of water conservancy, electric power and other national key projects. Corrugated pipe and accessories consisting of prestressing hole-forming system should meet the needs of post-tensioning prestressing grouting; the connection between pipe and tube, in addition to the hot welding connection, should also provide a special sealing connection device, this device should be with a hole grouting process of exhaust, drainage, slurry and observation of the efficacy of the discharge pipe, in order to achieve pressure grouting or vacuum-assisted grouting.

      

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

Advantages
1. Have a certain strength that is sufficient to maintain its shape and resist damage, penetration or deformation during construction;
2. Sufficient flexibility to accommodate special forms of prestressing tendon laying;
3. Have certain resistance to abrasion in order to prevent the orifice from being destroyed by the prestressing tendons during cable transfer and tensioning.
4. The cross-sectional area inside the bellows is at least 2~2.5 times of the prestressing tendons
5. With certain sealing, to ensure the sealing connection between bellows and anchorage, bellows and bellows;
6. Have a certain bonding ability


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
