Virgin White PTFE Pipe Specifications and Dimensions The specifications and dimensions of virgin white polytetrafluoroethylene (PTFE) pipes are summarized below based on industry standards and product data: I. Basic Specifications and Dimensions Size Notation Dimensions are typically denoted as inner diameter (d) × wall thickness (δ) or inner diameter × outer diameter, in millimeters (mm)56. Common Metric Sizes (ID × OD): 2×4, 3×5, 4×6, 5×7, 6×8, 8×10, 8×12, 9×12, 10×12, 12×14, 14×16, 16×18, 18×2056. Imperial Sizes: 1/8 inch (1.6×3.2), 1/4 inch (3.96×6.35), 3/8 inch (6.35×9.525), 1/2 inch (9.5×12.7), 3/4 inch (15.88×19.05), 1 inch (22.2×25.4)56. Wall thickness tolerance: ±0.1–0.3 mm (customizable)7. Classification by Standard QB/T 4877-2015: SFG-I: PTFE tubes processed from dispersion resin. SFG-II-A: Processed from suspension resin, for electrical insulation (non-conductive). SFG-II-B: Processed from suspension resin, specialized for fluid transport. SFG-II-C: Processed from suspension resin, general-purpose tubing. SFG-II: Blended with recycled resin. II. Key Performance and Technical Standards Physical Properties: Density: ≥2.10 g/cm³ (SFG-I) ≥2.14 g/cm³ (SFG-II-A/B/C). Tensile Strength: ≥15.0 MPa (wall thickness ≤3 mm) ≥20.0 MPa (wall thickness >3 mm). Elongation at Break: ≥150%. AC Breakdown Voltage: ≥20 kV/mm (SFG-II-A). Performance Tolerance2: Temperature Range: -60°C to +260°C. Corrosion Resistance: Compatible with strong acids, alkalis, and organic solvents. Pressure Capacity: Positive pressure: 1.6 MPa Negative pressure: 77 kPa. International Standard: ASTM D1710: Specifies performance for electrical, mechanical, chemical, and medical applications. III. Customization and Applications Customization Support: Non-standard sizes available (e.g., customization starting from 50 mm base dimensions)7. Custom wall thicknesses (e.g., 0.5–15 mm)37. Typical Applications2: Chemical Industry: Transmitting corrosive fluids/gases. Medical: High-purity gas/biopharmaceutical pipelines. Electronics: Insulating sheaths, component protection. Food Industry: Alcohol/beverage transport (non-toxic compliance).
