CPVC Pipe Production Process
Material Preparation – Primary raw material is Chlorinated Polyvinyl Chloride (CPVC) resin, selected for its superior heat and chemical resistance.
Mixing & Preheating – Raw materials are precisely blended per the formula, premixed at controlled temperatures to ensure uniformity, then preheated to the optimal extrusion temperature range.
️ Extrusion Molding – A single-screw or twin-screw extruder pushes the preheated compound through the die head. Precise temperature control across all heating zones is critical to ensure smooth flow and proper pipe formation.
❄️ Cooling & Shaping – The extruded pipe is rapidly cooled to lock in dimensional stability, then passed through shaping equipment to guarantee uniform diameter and wall thickness.
✂️ Traction & Cutting – The shaped pipe is drawn by a tractor and cut into standard lengths (or custom lengths per client specifications).
️ Printing & Inspection – Brand logos, specifications, and applicable standards are printed on the pipe, followed by rigorous quality inspection covering appearance, dimensions, mechanical properties, and flame retardancy to ensure full compliance with standards and customer requirements.
CPVC Pipe Application Areas
Hot & Cold Water Distribution – Ideal for residential and commercial plumbing systems.
Fire Protection Systems – Compliant with NFPA 13D (one- and two-family dwellings & manufactured homes), NFPA 13R (low-rise residential occupancies), and NFPA 13 (light hazard occupancies).
♻️ Reclaimed Water Piping – Suitable for purple pipe reclaimed water systems.
❄️ Chilled Water Piping – Reliable performance in chilled water distribution.
️ Hydronic Heating Systems – Works with radiators, fan coils, and other hydronic distribution networks.
Industrial Process Piping – Applicable to a wide range of industrial and process piping applications.
