Description of SBG500 HDPE/PP Double Wall Corrugated Pipe Extrusion Line:

Diameter scope: (ID) Φ200mm-Φ500mm
Double wall corrugated pipe Features:
In addition to general plastic pipe has good corrosion resistance,high insulation,inner wall smooth,small flow resistance and other characteristics. Double wall corrugated pipes are structurally optimized for the maximization of the utilization features. The shaped exterior wall insures a very good ring stiffness,an optimal flexibility - rigidity balance,stability towards the soil in underground sewer systems due to the exterior profiles. It allows a slight curving etc. At the same time,the pipe's specific weight is significantly decreased compared to classical systems,offering supplementary advantages for handling,storage and installation.HDPE/PP Double Wall Corrugated Pipe Making Production /Machine 
Double wall corrugated pipe line Features: 
The corruated pipe production line is developed with the ninety times advanced technology of West Europe by our company. The machine is equipped with double tube single-control stainless steel spraying shaper to form a production line. It avoids a waste condition when one tube is adjusted and the other one is affected. The auto single-control double haul off and cutter are combined with the front shaping technology to make operation more flexible. Let you enjoy economic benefit which is brought about by separately control double-tube extruding. It can make fully use of the extruding capacity of the extruder. Even if it produces small diameter pipe,it can get great output,too.
Single Screw Extruder:

 High speed and efficiency single screw extruder is specially designed for extrude HDPE,LDPE,and PP 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 feed material by two plastic extruders. It can make the inner and outer layers produce different material and guarantee high efficiency extrude.
Die head: 

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

Corrugator is adopted horizontal structure with chain type transmission,equipped with open water cooling system and vacuum forming system. It greatly increases the production speed. The belling on line function decreases investment cost and improves production efficiency. Mold block moving adopts synchronous upper and lower mechanical drive system and advanced self-lubrication system. It assures moving accuracy and 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.
