MPP three-layer co extrusion composite pipe production line

MPP three-layer co extrusion composite pipe production lineMainly used for the production of MPP material pipes, Zhangjiagang Huade Machinery Technology Co., Ltd. has long been committed to the research and improvement of this production line. With advanced technology, it has become the company's flagship product and its equipment is sold worldwide.

MPP pipe, also known as MPP power cable protection pipe, is divided into excavation type and non excavation type. MPP non excavation pipe is also known as MPP top pipe or support pipe. MPP pipes use modified polypropylene as the main raw material. It has the characteristics of high temperature resistance and external pressure resistance, and is suitable for cable conduit pipes of high-voltage transmission lines above 10KV. It has high-quality electrical insulation, high thermal deformation temperature, and low-temperature impact performance. Widely used in municipal, telecommunications, power, gas, and water pipeline projects.

This production line has the ability to produce MPP pipes with diameters ranging from 75 to 315mm, which can meet the production requirements of commonly used MPP pipe specifications (110 to 250mm). It has a wide production range and strong versatility.

Features and functions

MPP three-layer co extrusion composite pipe production lineSelect efficient extruders specifically designed for PP and MPP pipes, with screws equipped with barriers and mixing heads, and a new type of slotted barrel for excellent plasticizing and mixing effects. The extrusion volume is large and very stable.

The mold head has the characteristics of low solution temperature, good mixing performance, low mold cavity pressure, and stable production.

A specially designed multi-stage vacuum sizing box that controls the vacuum degree, ensuring the dimensional stability and roundness of the pipes.

The operation and time of the entire production line are programmed and controlled by PLC, with a well-designed human-machine interface. All process parameters can be set and displayed through the touch screen.

MPP uses modified polypropylene as the main raw material, which does not require extensive dredging, excavation, or damage to the road surface. It can be used for laying pipelines, cables, and other construction projects in special areas such as roads, railways, buildings, and riverbeds. Compared with the traditional 'digging trenches and burying pipes' method, non excavation power pipe engineering is more suitable for current environmental protection requirements, removing disturbing factors such as dust flying and traffic congestion caused by traditional construction. This technology can also be used to lay pipelines in areas where excavation operations cannot be carried out, such as historical sites, urban areas, crop and farmland protection areas, highways, rivers, etc.

The commonly used specifications for pipes are 50mm to 250mm in diameter, divided into ordinary and reinforced types. The ordinary type is suitable for excavation and laying construction, as well as non excavation crossing construction with a burial depth of less than 4M; The reinforced type is suitable for non excavation crossing construction projects with a burial depth greater than 4M. This product has passed the testing of the National Chemical Building Materials Testing Center and achieved good social and economic benefits.

It can be widely used in municipal, telecommunications, power, gas, tap water, heat and other pipeline projects.
