What is Bracket 20mm EG PPRc ?

 

Bracket 20mm EG PPRc PN 25 provides specialized support for high-performance piping systems. It securely clamps 20mm-diameter PPRc pipes rated PN 25 (25 bar), which HVAC and high-pressure water supply applications commonly require.

1. Description and Usage

This bracket acts as a mounting and stabilizing element.

• HVAC Systems: Used for chilled water lines in air conditioning or hot water lines in boiler/radiator heating systems.

2. Technical Specifications

The PN 25 rating indicates that the system (and its supports) is built for high-stress environments.

Feature	Specification
Material	High-grade Polypropylene (PPR-Type 3) or Galvanized Steel with Rubber Lining
Diameter	20mm (Standard for 1/2″ equivalent PPR pipes)
Pressure Rating	PN 25 (Withstands up to 2.5 MPa or 25 bar at 20°C)
Temperature Range	-20°C to +95°C
Fixing Hole	Typically 5.5mm to 8mm for wall plugs/screws
Standard Compliance	DIN 8077/8078 (German Standard) or ISO 15874

3. Installation Guidelines

Proper spacing and alignment of brackets ensure the long-term integrity of the HVAC or plumbing system.

Step-by-Step Installation:

1. Marking: Use a chalk line or spirit level to mark the path of the pipe on the wall or ceiling.

2. Drilling: Drill holes at the marked intervals. For a 20mm pipe, the spacing should be approximately:

   • Cold Water: Every 60–80 cm.

3. Mounting: Insert wall plugs and screw the base of the bracket firmly into the surface.

4. Insertion: Push the 20mm PPRc pipe into the bracket.

5. Expansion Gaps: When installing long runs for hot water, do not overtighten all brackets; leave some as “sliding supports” to allow the pipe to move during thermal expansion.⁶

4. Key Advantages

• Corrosion Resistance: The EG coating or plastic body prevents the bracket from rusting in damp HVAC environments.

• Vibration Dampening: Often features a snap-in design that reduces noise from water hammer or HVAC pump vibrations.

• Load Bearing: PN 25 brackets are reinforced to handle the weight of heavy-walled high-pressure pipes.

• Aesthetics: Provides a clean, professional finish for exposed pipework in utility rooms or basements.

Note: For HVAC applications involving chilled water, ensure the bracket is compatible with the pipe insulation (lagging) to prevent “sweating” or condensation at the support points.
