concrete pipe forming equipment supplier

We are a leading manufacturer of concrete pipe machines with more that 20 years' history.  By importing advanced technology and high-precision processing equipments,   Our products are famous for high produtivity ,  easy operation, durability and reliability. By now, our concete pipe machines have been all over the world such as Sudan, Nigeria, Kenyan, Ethiopia etc.  

1. Introduction of Concrete Pipe Mould

Concrete pipe mold falls into two types according to the way of connection of moulded drain pipes: rigid joint and flexible joint; pipe mold fall into three types according to the joint shape of shaped drain pipes: plain top, tongue and groove, bell and spigot; pipe mold fall into Ⅰ,Ⅱ,Ⅲ grades according the grade difference of external pressure load of shaped drain pipes

2. Features of Concrete Pipe Mould

2.1 The adoption of integrated design is reinforced design of leakproof slurry, no rough edges on which the mouth of pipe joints, easy mold-opening.

2.2 The friction rings in the molds are all made of 45 cast steel with durablity.

2.3 The steel plate we use is produced by Laigang which is one of the four major steel mills, and its abrasion resistance will be guaranteed.

2.4 The carbon-dioxide arc welding is applied into the all welding. The plasma cutting machine is used for cutting. Welding seam is smooth and nice, and the cutting seam is very exquisite. All above ensure the mold tough and durable and extend the service life greatly.

3. Technical Indexs of Concrete Pipe Mould

Mold Diameter(mm)	Cylinder Thickness	Hooped, Longitudinal Reinforcement
300~600	6mm	8mm×60mm
800~1000	8mm	10mm×80mm
1200~1500	10mm	12mm×120mm
1500~2000	10mm	14mm×150mm

two different ways to produce concrete pipe,cement culvert pipe

 centrifugally spun concrete pipe system

             

This technique adopt wet concrete, the pipe body structure has various layers when formed,thus it influence the concrete load resistance. Concrete is usually C30  ,can also do C40. But the pipe nozzle rigidity is lower than the body, not good to be a jacking pipe. During the forming process, concrete pipe mould spun quickly on the centrifugal machine,so does the steel wire cage. These tmay lead to two situation of short life span of the concrete pipe.

1.Steel wire cage has unfasten welding point, result in the steel wire shift or missing,make the pipe locally without steel wire.

2.Wire cage is hardly set in the middle ,Reinforcing mesh is eccentric,namely wire cage protection layer is not even. What’s more, this technique requires large quantity mould to ganrantee the the production, with the mould size deviation and frequent de-molding operation, steel moulds transformation easily occur. Thus lead to Pipe roundness, the perpendicularity of the nozzle, the size of the pipe diameter size and length,which has a bad influence to project quality. The pipeline leakage will cause surface subsidence, can pollute on either side of the soil and groundwater.

roller suspension concrete pipe system

                 

Adopt harsh concrete, pipe structure is even, has great load resistance capacity. We adopt c30 and c40 concrete as raw material. Lower noise than centrifugal technique when pipe forming, clean environment than centrifugal technique. The short coming is, it requires more higher wall 

thickness when produce small nozzle pipe to reach the anti-leakage requirement.
