The PP Pipe Natural Class D - 12 Bar (Heavy Gauge) is purpose-built for higher-pressure industrial applications where additional mechanical strength and reliability are essential. Manufactured from natural polypropylene block copolymer (PP-B), this pipe features a thicker wall construction to safely accommodate increased internal pressures while maintaining the material’s inherent chemical resistance and purity.

Compared with lower pressure classes, the Class D heavy gauge pipe is designed for more demanding duty cycles, making it ideal for pressurised process lines where safety margins and long-term performance are critical. The smooth internal bore ensures efficient flow characteristics, helping to minimise pressure losses even in complex or extended systems.

• Heavy gauge design: Increased wall thickness for 12 bar pressure systems
• Higher pressure capability: Suitable for demanding industrial installations
• Natural polypropylene material: Unpigmented PP-B for purity-sensitive processes
• Excellent chemical resistance: Performs reliably with aggressive fluids
• Smooth internal surface: Supports high flow efficiency and reduced turbulence
• Corrosion-free construction: Will not rust, rot, or degrade like metal pipework
