Pipe Support for Large Diameter Pipe

For large diameter piping systems, support selection directly affects long-term reliability and thermal flexibility. Our Pipe Support for Low Temperature models handle cryogenic service down to -196°C without losing load capacity, while Seismic Pipe Support assemblies restrain movement during seismic events in compliance with ASCE 7. For lines connected to pumps or compressors, the Anti Vibration Pipe Support reduces fatigue from mechanical oscillation, and the Shock Absorbing Pipe Support absorbs water hammer and pressure surge loads. These supports share a common heavy-frame design suited for nominal pipe sizes from DN200 to DN1600.

The Large Diameter Pipe Support series is built for high-load industrial piping, including refinery transfer lines, power plant main steam headers, and district cooling networks. Each unit uses a welded carbon steel frame with optional stainless steel hardware to withstand aggressive environments. The saddle curvature is precision-formed to match pipe OD, and the base plate includes slotted holes for field alignment. Key technical parameters are listed below.

• Modular design supports pipe diameters from 8" to 64" (DN200–DN1600) with custom sizes available
• Vertical load capacity up to 500 kN and lateral restraint up to 200 kN
• Operating temperature range from -196°C to +450°C depending on slide plate material
• Hot-dip galvanized or epoxy-coated finish for corrosion resistance in C3/C4 environments
• Adjustable height from 150 mm to 800 mm above structural steel
• Optional PTFE, 25% glass-filled PTFE, or graphite slide plates for thermal expansion

Technical Specifications

The welded base frame accepts 4-bolt or 8-bolt anchorage patterns, and the saddle clamp halves are pre-drilled for quick assembly around existing pipes. Insulation shields from 30 mm to 200 mm thick can be incorporated without changing the support geometry. For lines with significant axial movement, spring cans or constant hangers can be mounted on the same base plate, reducing the need for separate support points. Standard documentation includes material test certificates per EN 10204 3.1, weld procedure specifications, and load test reports. Custom paint systems, stainless steel fasteners, and pre-assembled insulation clamps are available on request.
