Case Study

Municipal Chemical Drainage Pipe Network Expansion

A major municipal piping contractor deployed our pp pipe extrusion line to manufacture chemical-resistant underground conduits for an industrial park expansion. Operating continuously at 420 kilograms per hour, the line extruded 200mm diameter PN16 pipes with uniform wall thickness and excellent burst strength. The intelligent cooling control system reduced thermal shrinkage by 18%, while gravimetric dosing saved 5% in raw resin usage. Over an eight-month production cycle, the facility manufactured 1.1 million linear meters of certified drainage piping with 99.5% operational uptime, fulfilling government tender requirements ahead of schedule and achieving complete capital investment payback within seven months of continuous factory operation.

High-Temperature Industrial Fluid Conveyance Line

Facing strict safety certifications for industrial fluid handling, a pipe converter installed our advanced extrusion machinery to produce certified polypropylene pressure pipes. The line processed high-molecular PP-R compound smoothly into 110mm hot-water conduits at a steady rate of 360 kg/h. Precise melt pressure transducers kept ovality deviations below 0.4%, ensuring superior socket-fusion joint integrity during field installation. Hydrostatic pressure testing confirmed a 20% improvement in long-term stress rupture resistance. The manufacturer successfully secured a multi-year regional industrial supply contract, generating a 35% increase in annual commercial piping revenues and expanding export distribution across three new international markets.

Subsurface Agricultural Irrigation Piping Project

To supply large-scale agricultural irrigation projects, a plastics converter adopted our high-speed pp pipe extrusion line. The machinery operated at extrusion speeds reaching 20 meters per minute, producing flexible 160mm agricultural drainage tubing with high crush resistance. Automated vacuum sizing tanks and high-flow spray cooling chambers stabilized pipe geometry instantly, preventing sagging or wall thinning. Scrap generation fell by 15% due to stable melt pressure control, while daily output volume rose by 30%. The company expanded market reach across three international agricultural regions, boosting quarterly export profitability and strengthening brand reputation for long-term piping system durability.

High-Performance Grooved Extruder and Barrier Screw

High-Performance Grooved Extruder and Barrier Screw

The heart of our pp pipe extrusion line features an advanced single-screw extruder equipped with a grooved feed housing and a specialized barrier mixing screw. This high-efficiency design maximizes solid conveying capacity while ensuring low-temperature, high-homogeneity melt plasticization at high rotational speeds. The bimetallic barrel and tungsten-carbide-coated screw flights provide exceptional resistance against abrasive wear and chemical corrosion, extending operational lifespan significantly. Enhanced thermal insulation jackets minimize radiant heat loss, contributing directly to a 22% reduction in overall electrical power consumption compared to conventional smooth-barrel extrusion systems used in modern industrial pipe manufacturing facilities, lowering lifetime operational costs substantially.
Intelligent Closed-Loop Vacuum Calibration and Cooling

Intelligent Closed-Loop Vacuum Calibration and Cooling

Precision downstream cooling and sizing are managed by a multi-chamber stainless steel vacuum calibration tank paired with closed-loop water spray cooling baths. High-flow vortex water nozzles and automated regulating valves maintain stable vacuum pressure, ensuring exact roundness and outer diameter tolerances on large-diameter pipes. Electronic position sensors synchronize the caterpillar haul-off tractor and planetary saw perfectly, delivering clean, burr-free cuts at exact pre-set lengths. This integrated automation eliminates manual intervention, reduces scrap rates to under 0.5%, and guarantees consistent mechanical performance across every manufactured pipe batch, maximizing factory yield and delivery confidence for demanding municipal projects.
