Qingdao Qinghang Plastic Machinery Co., Ltd. specializes in manufacturing professional plastic PVC pipe production lines. Engineered for high thermal stability and consistent throughput, our advanced manufacturing plants cater to global civil contractors and B2B pipe distributors looking to optimize their manufacturing scale.
Our heavy-duty rigid PVC pipe manufacturing machine is an all-in-one automatic pipeline system engineered to realize precise control from raw material infeed to the finished stacked bundle:
Extrusion System: Equipped with an SJSZ Conical Twin Screw Extruder, featuring a twin-screw volumetric dosing feeder and an automatic vacuum loading system for stable material feeding.
Premium Electrical Components: The entire control system integrates premium global electronics, utilizing Omron temperature controllers for precise thermal regulation and Siemens contactors for rugged operational reliability.
Bracket-Type Extrusion Die/Mold: Utilizes a specialized bracket-type flow distribution die. This tool splits the melt seamlessly to eliminate knit lines, guaranteeing perfectly smooth, even, and flawless pipe inner and outer walls.
Downstream Automation Integration: A fully closed-loop line comprising a vacuum sizing calibration water tank, a high-precision online laser inkjet printer, a synchronized three-claw (three-caterpillar) traction haul-off machine, an automatic in-line film wrapping machine, a dust-free cutting machine, and an integrated unloading stacker.
Polyvinyl Chloride (PVC) pipes are among the most widely utilized plastic piping solutions globally. Depending on material hardness and technical standards, they serve as core mainforces across infrastructure, construction, and agricultural sectors:
Indoor & Outdoor Drainage Systems: Hard Polyvinyl Chloride pipes (PVC-U) feature a rigid texture and excellent corrosion resistance. They are the default standard for building downspouts, rainwater collection pipes, and municipal sewer engineering.
Industrial Effluent Discharge: Due to their outstanding chemical resistance against acidic and alkaline fluids, these pipes are heavily relied upon in the chemical processing, electroplating, and laboratory sectors to safely transport industrial wastewater.
Wire & Cable Protection: Utilizing PVC’s natural dielectric properties and excellent electrical insulation, these tubes serve as electrical conduit pipes or underground cable sheaths, shielding lines from external compression or environmental damage.
Agricultural Irrigation & Aquaculture: Highly favored for low-pressure farm water delivery, sub-surface drip irrigation networks, and commercial fishery distribution grids. They are non-toxic, hygienic, cost-effective, and easy to install onsite.
Mining Shaft Infrastructure: Custom PVC pipes conforming to specific flame-retardant and anti-static industrial standards are widely deployed in underground coal mines for fresh-water delivery, safety drainage, and high-pressure ventilation (compressed air) systems.
