1. Diameter scope: (ID) Φ225mm-Φ800mm

Double wall corrugated pipe inner layer smooth, outer layer trapezoidal corrugated -size , hollow wall between inner layer and outer layer. The special design of pipe wall structure makes the pipes have many advantages such as: high ring stiffness, light weight, high pressure, good toughness, corrosion resistance, good wear resistance, construction convenient, low installation cost, long service life and so on. Double wall corrugated pipe is widely used in areas such as the transformation of municipal engineering, construction, industrial and agricultural drainage, agricultural water-saving irrigation and sewage treatment works and other fields. Double wall corrugated pipe is the best product instead of traditional cement pipe, cast iron pipe and other materials pipe.

3. Double Wall Corrugated Pipe Line Features:

In order to meet the demand of plastic market, HUASU Company designed and developed this HDPE Double Wall Corrugated Pipe Extrusion Line SBG800 by absorbing advanced technology from foreign countries plastic machinery industry. This HDPE Double Wall Corrugated Pipe Extrusion Line is the latest study achievement in the plastic extruding area. The whole extrusion line is suitable for the high speed extrusion of HDPE, LDPE, and PP material. The complete line adopts directly extrude (two extruders co-extruding) and forming technology, human-machine interface control system. It makes high automation degree, reliable quality and stable production become true. And this pipe production line wins our home and abroad customers’ good reputation.

Extruder: High speed, high efficiency extrusion single screw extruder is specially designed for extruding PE material, grooved barrel, equipped with the lower noise fan, high speed and hard gear reducer. The inner and outer layers of the corrugated pipe are independently fed material by two extruders. It can make the inner and outer layers produce different material and guarantee high efficiency extruding.

Die head: The extrusion die head has two channel structure, nitriding and polishing handling, special designed mouth molds, suitable for different material and different ring stiffness pipe production. The special molds structure assures the inner and outer layer wall thickness even and forming stability.

Corrugator :Corrugator is adopted horizontal structure with shuttle type transmission, equipped with advanced water cooling system and vacuum forming system. It greatly increases the production speed. Special belling on line function decreases investment cost and improves production efficiency. Reducing quantity of mold blocks can reduce investment cost and energy consumption. Mold blocks adopt Siemens servo motor drive and advanced self-lubrication system. It assures moving accuracy and plastic pipe quality stability. 

Mold blocks: They are corrugated forming molds which are formed by special aluminum alloy material through precision casting. They have high precision and strength, and excellent heat dissipation.

Cutting machine: High-strength alloy steel blade, Rotary cutting, smooth pipe incision, dustless cutting. The tracking device makes the cutting location precision. Germany Siemens professional PLC programmed controlling system makes operation easy and sensitive.

Control system: It adopts Siemens professional PLC control system, 15 "large color touch screen human-machine interface, high automation, reliable running, easy operation, remote communication function which can realize remote fault diagnosis and rule out the possibility.
