2. Extrusion or Injection Molding ✔
Material is melted and shaped under automated, CNC-controlled extrusion or injection systems. Precision dies ensure exact sizing and wall thickness.

3. Fitting Formation / Demolding ✔
Molten PVC is pressed into steel/aluminum casting molds or forged under high pressure; complex geometries (Tee, Elbow, etc.) are CNC-trimmed for accuracy.

4. Cooling, Finishing, and Inspection ✔
Rapid cooling (water spray bath), deflashing, and surface finishing. Each batch is hydrotested and dimensionally inspected against ANSI/ASTM tolerances.

5. Marking & Packaging ✔
Laser printing of batch, certificate and ISO/CE marks. Automated packaging lines ensure fast, error-free dispatch.

Professional FAQ: PVC Pipe Fitting

1. What material grades are used in PVC pipe fitting production?: Mostly uPVC (unplasticized PVC, K67), which offers high tensile strength, chemical resistance, and long-term stability. Some specialty fittings may use CPVC or reinforced blends for higher temperature applications.
2. How to select the right size and pressure rating?: Match the PVC pipe fitting outer diameter and pressure class (PN rating) to your existing pipe according to ISO/ANSI standards. Factor in design pressure, fluid velocity, and safety margin.
3. Which joining methods are compatible?: Chemical solvent cement (bonding), mechanical coupling (compression/threaded), and flange jointing. Different methods suit potable water, sewage, or chemical lines accordingly.
4. Are PVC pipe fitting systems corrosion-proof?: Yes – they are immune to nearly all acids, bases, and salts, but not recommended for concentrated organic solvents or chlorinated hydrocarbons (consult EN ISO 15493 chemical resistance chart).
5. What is the typical service life?: Over 50 years when operated within design parameters (pressure, temperature, UV protection if exposed). Lifespan is validated via ISO 9080 regression tests.
6. Which certifications should PVC pipe fitting suppliers have?: ISO 9001 (factory QA), ISO 1452/ASTM D2466 (product quality), SGS or TÜV third-party reports, CE/WRAS for EU and UK potable water compliance.
7. How to ensure correct installation?: Follow the manufacturer’s recommended procedures: clean, dry joints; use correct solvent cement or torque; align pipes to avoid stress. Site supervision by a certified installer is advised for large projects.
