In addition to civil building engineering, 32mm PVC standard electric pipes are also widely used in municipal low-voltage electrical projects, garden landscape wiring, mechanical equipment internal wiring protection, and indoor renovation hidden wiring projects. With the continuous development of the construction industry and the improvement of electrical safety standards, the market demand for high-quality standard 32mm PVC conduits maintains stable growth, driving the continuous upgrading and standardized development of supporting Plastic Pipe Extrusion Line equipment.
1.2 National and International Production Standards for 32mm PVC Conduit
Qualified 32mm PVC electric pipes must comply with strict dimensional and performance standards to ensure electrical safety and service life. In terms of dimensional standards, the standard outer diameter of 32mm PVC conduit is fixed at 32mm with a tolerance range of ±0.3mm, and the wall thickness is divided into light type, medium type, and heavy type according to load-bearing and anti-pressure requirements, with wall thickness ranging from 1.2mm to 2.0mm. The pipe roundness error must be controlled within 1%, and the pipe surface must be smooth without cracks, bubbles, scratches, and depressions to avoid wire abrasion during cable penetration.
In terms of performance standards, 32mm PVC electric pipes need to have excellent flame retardant performance, with oxygen index meeting national building material flame retardant standards, self-extinguishing within a specified time after leaving the fire source, and no open flame combustion. Meanwhile, the pipes must have good insulation performance, pressure resistance, aging resistance, and corrosion resistance, adapting to long-term indoor and semi-outdoor use environments. All FAYGO 32mm PVC conduit extrusion lines are debugged and produced in strict accordance with international standard parameters, ensuring that all finished pipes fully meet standard specifications and pass industry quality inspection smoothly.
1.3 Production Difficulties of Standard 32mm PVC Conduit
Although 32mm PVC conduit is a conventional standard pipe, its small-diameter forming process has unique technical difficulties in actual production.

3.2 Screw Extrusion and Melt Forming
The uniformly mixed PVC materials enter the extruder barrel, and are heated, squeezed, sheared and plasticized by the screw to form uniform and stable PVC melt. Under the push of screw rotation, the melt is evenly extruded through the special 32mm pipe mold to form a tubular pipe blank with preliminary dimensions. The multi-stage independent temperature control system of the extruder ensures that the melt temperature is always in the optimal plasticization range, avoiding material decomposition, yellowing and uneven plasticization.
3.3 Vacuum Sizing and Gradient Cooling Shaping
The high-temperature pipe blank extruded from the mold enters the vacuum sizing machine immediately. Under the action of negative pressure vacuum, the pipe blank closely fits the inner wall of the sizing sleeve to complete precise shaping of 32mm standard outer diameter. Then the pipe passes through the multi-stage circulating water cooling tank, and gradually cools down and solidifies through gradient cooling to fix the pipe shape, eliminate internal stress, and ensure stable pipe roundness and dimensional accuracy. After cooling and shaping, the pipe completely meets the standard size requirements of finished products.
3.4 Constant-Speed Traction and Stable Transmission
The cooled and shaped 32mm PVC pipe is stably pulled forward by the traction machine at a constant speed.
