Customizable Pipe Insulation Supports Systems 0.98 - 9.84 Inch Insulation Thickness
The following criteria shall be considered in the selection of low-temperature pre-insulated pipe supports:
- Vertical, lateral and axial support design load limits
- Vertical, lateral, and axial support design travel limits
- The temperature of the cryogenic pipe support, at the pipe surface, and ambient conditions
- All test or pre-operational loads that may exceed normal operating conditions
- Any dimensional clearances needed during installation and operation should be specified
- Material for any items that will be welded directly to the pipe
- All loading and displacements caused by seismic, hydraulic surge, or other disturbances
- The temperature at the support steel
Insulated pipe support system is mainly used for the support of insulated pipes and equipment. The system can bear all kinds of loads brought by the piping system, and it is also a part of the cold insulation of the pipeline.
- Sliding Pipe support system
- Guide pipe support system (including guide support for vertical pipe)
- Limit pipe support system
- Fixing pipe support system Bearer
- Supporting bracket system
A complete insulated pipe support system consists of insulated pipe supports and cold insulation materials. The primary cold insulation material is high density polyisocyanurate (HDPIR).
The system may also include these auxiliary materials as required:
- Damp proof layer
- Metal protective layer
- Rubber plate
- Metal pipe clamp
- Bolt and nut
- Butterfly spring
- Cold insulation washer
- Polytetrafluoroethylene sliding pair
- Steam insulation resistance
Primarily used for bearing and heat insulation of pipes and equipment in:
- Petrochemical plants
- Liquefied gas plants
- Refrigeration warehouses
- Central air conditioning systems
All parts are assembled in workshop. Finished products are wrapped in anti-ultraviolet polythene film and packed in wooden cases.
HDPIR is a foaming polymer combining features of plastic, rubber and cork. Composed of millions of tiny, uniform sealed cells, it offers low density, low thermal conductivity, and low water absorption with performance superior to timber.
