Why New Age RISER CLAMP?
Floor-Mounted Stability System
Engineered to transfer vertical pipe loads directly to structural elements. No hanger rods, no ceiling attachments, no load path complications—just solid ground support.
Egyptian-Made Structural Precision
Manufactured at our Abu Rawash facility using precision forming and machining equipment. Every clamp maintains dimensional accuracy for consistent load transfer and installation.
Professional Load Transfer Design
Each size calculated for specific pipe weights plus contents, seismic loads, and thermal expansion forces. Engineers receive documented load paths for structural calculations.
Code-Compliant Installation
Meets Egyptian Mechanical Code requirements for vertical pipe support. Compatible with NFPA 13 and 14 sprinkler system installation standards.
Complete Installation Package
Includes Grade 8.8 bolts matched to clamp size and load requirements. Pre-drilled holes ensure proper bolt engagement and load distribution.
Contractor-Proven Reliability
Trusted in Egypt’s tallest buildings where vertical pipe support cannot fail. Used by top contractors in high-rise MEP installations.
Primary Applications
Fire Protection Riser Systems
Supporting vertical sprinkler risers, standpipes, and fire pump discharge lines between floor levels in high-rise buildings.
HVAC Vertical Distribution
Chilled water risers, heating hot water lines, and condenser water piping in commercial buildings and residential towers.
Plumbing Riser Support
Domestic water supply and waste lines in multi-story buildings, especially at floor penetrations and equipment levels.
Industrial Process Piping
Vertical runs in manufacturing facilities, power plants, and process industries where floor-mounted support is required.
Installation Requirements & Procedures
Structural Prerequisites
- Floor Loading: Verify structural capacity for concentrated pipe loads
- Bearing Surface: Ensure flat, level contact area minimum 100 cm²
- Access Requirements: Maintain 100mm clearance for bolt tightening
- Pipe Preparation: Install pipe guides or sleeves at floor penetrations
Professional Installation Steps
- Position Verification: Place clamp at design elevation on structural element
- Pipe Alignment: Ensure vertical pipe is plumb and properly positioned
- Clamp Assembly: Place clamp around pipe at support point (typically below flange or coupling)
- Bolt Installation: Insert Grade 8.8 bolts through precision-drilled holes
- Torque Application: Tighten bolts to specified torque (see table below)
- Load Verification: Confirm direct bearing contact with structural element
- Final Inspection: Check pipe restraint and load transfer path
Installation Torque Requirements
- M10 Bolts: 40-50 Nm
- M12 Bolts: 70-85 Nm
- Re-torque: Check bolts after initial loading period
Structural Integration Guidelines
Floor Slab Requirements
- Minimum Thickness: 150mm reinforced concrete slab
- Concentrated Load: Design for pipe weight plus 50% dynamic factor
- Reinforcement: Additional reinforcing may be required at support points
- Edge Distance: Maintain minimum 75mm from slab edges
Steel Beam Mounting
- Flange Bearing: Direct contact with top flange of structural steel
- Beam Capacity: Verify beam can support concentrated loads
- Connection Details: May require additional plates or stiffeners
- Lateral Restraint: Consider lateral pipe movement and thermal expansion
Load Path Verification
- Direct Transfer: Load path must be clear from pipe through clamp to structure
- No Suspended Loads: Clamp must not hang from overhead elements
- Structural Analysis: Include clamp loads in structural design calculations
- Seismic Considerations: Account for seismic forces in high-seismic zones
