ABS Flanges Metric

ABS metric flanges provide a secure, demountable method of joining ABS pipework. They are commonly used where pipe systems may need to be dismantled for maintenance, inspection or future expansion, such as connections to valves, pumps, meters and other flanged equipment.

Manufactured from acrylonitrile butadiene styrene (ABS), these fittings deliver excellent durability without the corrosion issues associated with metal flanges.

ABS flanges offer a strong and practical alternative to traditional metal flange systems.

Key benefits include:

• Lightweight and easy to handle on site
• Corrosion and chemical resistant
• Non-toxic and suitable for potable water applications
• Demountable design for easy maintenance
• Reliable performance across a wide temperature range

This category contains everything required to assemble a complete ABS metric flanged joint:

ABS Metric Stub Flanges

• Solvent welded directly to ABS pipe with solvent cement and cleaner
• Used with backing rings and gaskets
• Ideal for demountable connections to equipment

ABS Metric Blanking Flanges

• Designed to seal the end of a pipe run
• Commonly used for isolation, commissioning or future expansion
• Manufactured to BS EN 1092-1

Backing Rings

• Provide structural strength to the flange joint
• Available in:
  • PN10
  • PN16
  • ANSI Class 150
• Manufactured from galvanised steel

Flat Gaskets

• Designed specifically for ABS serrated-face stub flanges
• Ensure reliable, even sealing within the joint

Nuts & Bolts

• Supplied as complete fixing sets
• Available in:
  • Bright Zinc Plated (Grade 8.8) - for general indoor and dry environments
  • 316 Stainless Steel (A4) - for corrosive, outdoor or hygienic installations

ABS metric flanges are widely used across a range of industries, including:

• Water treatment systems
• Industrial process pipework
• Chemical handling installations
• Food and beverage applications
• Plant rooms and utility services

To assemble a complete ABS flanged joint, you will typically require:

• 2 × ABS stub flanges
• 1 × flat gasket
• 2 × backing rings
• Appropriate nuts and bolts

Stub flanges are solvent welded to the pipe using ABS solvent cement and cleaner, forming a permanent bond before the flanged joint is bolted together.
