Popular DN50 DN100 Automatic Corrugated Metal Prestressed Hoses Prestressed Metal Bellows Forming Machine
This machine is a kind of equipment for producing prestressed concrete reserved tunnel metal bellows makes the galvanized steel strip coil into double 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.
Process:
Raw material (steel trip)---purge tank---Conduction frame---contoured roll---Winding head---undercut---pipe formation---cutting
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 USA , Austrilia , 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.
