What is CPVC Pipe?
Chlorinated polyvinyl chloride (CPVC) pipe features high-temperature resistance (up to 93 °C), chemical corrosion resistance, and flame retardancy. It is widely used in chemical fluid transport, automatic fire sprinkler systems, and hot water piping networks.
The market trends of CPVC pipe extrusion machines:
CPVC pipe offers 1.5 times the strength of standard PVC pipe. With favorable policies and strong profit margins, CPVC demand is growing at over 15% annually. Blesson’s CPVC extrusion line delivers high output at 180 kg/h (tested with Lubrizol CPVC resin), with a daily capacity of 1.5 tons, enabling customers to achieve rapid ROI and export value enhancement.

The core extruder of the CPVC pipe production line is equipped with a screw custom-designed for CPVC composite materials. Combined with a precision zoned temperature control system, it achieves stable plasticization and efficient extrusion of CPVC raw materials. Driven by a WEG permanent magnet synchronous motor, the extruder features low energy consumption, high efficiency and effective noise reduction, significantly reducing customers’ production costs.

The extrusion die of the CPVC pipe production line adopts an optimized flow channel structure, which ensures high extrusion efficiency while maintaining a reasonable compression ratio, contributing to the improvement of dimensional stability and surface quality of finished pipes. In terms of structural design, Blesson’s CPVC pipe equipment emphasizes modularity and convenience, facilitating quick installation, disassembly and daily maintenance, thus improving the efficiency of changing pipe diameters and wall thicknesses.

The vacuum tank of the CPVC Plastic Pipe Production Line is equipped with an independent control system and a negative pressure closed-loop automatic adjustment function. While ensuring stable vacuum pressure, it reduces energy consumption, and plays a significant role in enhancing the shaping and surface quality of CPVC pipes. The CPVC Pipe Making Machine, combined with structural optimization and noise reduction treatments, enables the vacuum tank of the CPVC Pipe Extrusion Line to operate with low noise and excellent energy-saving performance.

The haul-off unit of the CPVC Pipe Production Line adopts the Inovance synchronous servo drive system, which can achieve precise speed regulation over a wide range and flexibly meet different traction requirements for pipes from small to large specifications. Each track of the haul-off machine in the CPVC Pipe Production Line maintains precise synchronization, ensuring smoother operation and more sensitive speed adjustment responses, thus providing continuous and stable power for the entire CPVC Pipe Production Line.

The swarf-free cutting machine of the CPVC Pipe Production Line is equipped with a high-efficiency, precise and low-noise swarf-free cutting device. The swarf-free cutting device of the CPVC Pipe Production Line is fully controlled by a Siemens PLC during the cutting process, enabling rapid responses to match the production rhythm. This not only increases the output of the entire CPVC Pipe Production Line, but also eliminates the debris and dust generated by traditional cutting methods, creating a cleaner and more environmentally friendly working environment.
