Comrise Large Diameter Solid Wall Wrapped Pipe Production Line Successfully Tested

Recently, a large diameter solid wall winding pipe production equipment in Comrise factory has entered the trial operation stage to ensure the quality of the machine. After several days of on-site debugging by the technical team, all parameters of the equipment have met the design requirements, and the operation is stable. The first batch of trial production pipes have all passed the inspection, and the customer has recognized the quality of the finished products.

Equipment composition and function

This production line consists of five parts: funny extruder, winding molding machine, cooling and shaping machine, cutting machine, and control system.

1. The extrusion system adopts an efficient single screw extruder, which has good plasticizing effect and high extrusion efficiency, ensuring uniform raw material temperature and providing stable raw material supply for subsequent molding.

2. The winding molding system is the core part of the entire line, consisting of molding molds and winding mechanisms. The mold can be adjusted according to the pipe diameter specifications, and the winding mechanism controls the interlayer composite angle of the pipe to achieve continuous forming of the pipe, ensuring machine operation and pipe quality.

3. The cooling and shaping system adopts a blower system to promote the cooling of the pipes, improve the production efficiency of the pipes, and the automatic unloading rack also ensures the cooling of the pipes

4. The cutting system adopts a row cutting machine, with a flat cut and a length error controlled within ± 2mm.

5. The control system is based on PLC and touch screen operation interface, displaying key data such as temperature, pressure, and speed in real-time for each section, supporting parameter storage and fault self diagnosis.

Performance and Application of Pipe Materials

The solid wall winding pipe machine used in this trial operation has a ring stiffness level of SN8 to SN16. The inner wall of the pipe is smooth, the friction coefficient is low, and the water flow capacity is strong; The outer wall is reinforced with a winding structure, which has better compressive and deformation resistance than traditional pipes of the same specification. The raw material used is high-density polyethylene (HDPE), which is resistant to acid and alkali corrosion and has a service life of over 50 years.

This type of pipe is mainly used in municipal drainage and sewage engineering, industrial wastewater treatment pipelines, agricultural water conservancy irrigation, and building community rainwater and sewage diversion renovation projects. In the laying of pipelines in soft soil foundations and settlement areas, their flexibility and interface sealing performance are particularly outstanding, which can effectively reduce construction difficulty and maintenance costs.

Debugging and customer feedback

During the trial operation, the Comrise technical team repeatedly calibrated key process parameters such as extrusion temperature curve, winding tension, and cooling water temperature. At present, the equipment has been running continuously for more than 72 hours without any abnormal shutdown, and the production capacity is stable at 8 to 12 meters per hour (depending on the pipe diameter).

The customer conducted tests on the appearance, dimensional deviation, ring stiffness, and impact performance of the first batch of pipes submitted for inspection, and all results were qualified. The customer stated that based on the samples, the uniformity of the pipe wall is better than the industry average, and they hold a positive attitude towards subsequent bulk purchases.
