GRP Puddle Flange Outside Diameter 660 mm PN16 Thickness 65 mm Hepco Company

GRP Puddle Flange (PN16) — Key Details for Saudi Projects

This GRP puddle flange from Saudi Hepco is designed for embedding through concrete walls and chambers to create a durable, watertight pipe penetration point. It is commonly used in Saudi infrastructure and site works for water supply, sewage, and irrigation networks where corrosion resistance and long service life are required.

Why Choose GRP for Puddle Flanges?

• Corrosion resistance: Helps reduce deterioration in aggressive soil and wastewater environments.
• Chemical resistance: Suitable for many municipal and industrial drainage conditions.
• High strength-to-weight: Easier handling on-site compared to many traditional materials.
• Long service life: Designed for reliable performance in buried and concrete-embedded applications.

Installation Notes (Best Practice)

• Verify DN 450 and PN16 compatibility with the connected GRP pipeline and system design.
• Before pouring concrete, confirm flange position, alignment, and the required clearance for bolt tightening.
• Use appropriate gaskets and bolting suitable for the application; tighten bolts evenly in a cross pattern to support uniform sealing.
• For water and sewage works, ensure the penetration detail meets project waterproofing requirements and site inspection criteria.

What to Check Before Buying

• Diameter & drilling: DN 450, 20 holes, 30 mm hole diameter, and PCD 585 mm must match the mating flange.
• Pressure rating: Choose PN16 when your line and fittings are designed for 16 Bar service.
• Standards compliance: Confirm the project requires BS/DIN/ISO drilling patterns listed above.
