The following criteria shall be considered in the selection of low-temperature pre-insulated pipe supports:
A. Vertical, lateral and axial support design load limits.
B. Vertical, lateral, and axial support design travel limits.
C. The temperature of the cryogenic pipe support, at the pipe surface, and ambient conditions.
D. All test or pre-operational loads that may exceed normal operating conditions.
E. Any dimensional clearances needed during installation and operation should be specified.
F. Material for any items that will be welded directly to the pipe.
G. All loading and displacements caused by seismic, hydraulic surge, or other disturbances.
H. The temperature at the support steel.
Insulated pipe support system is mainly used for the support of Insulated pipes and equipment. The insulated pipe support 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.
Types
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.
Compositions
A complete insulated pipe support system is composed of insulated pipe supports and cold insulation materials. The cold insulation material is the most important part of the insulated pipe support system, which is high density polyisocyanurate (HDPIR).
In addition to the main cold insulation materials, the insulated pipe support system can also be equipped with the following auxiliary materials according to the requirements: 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, etc., in order to meet the design needs and ensure the safe and reliable use of the pipe support system.
Application
It is mainly used for bearing and heat insulation of pipes and equipment in petrochemical plant, liquefied gas plant, refrigeration warehouse and central air conditioning system.
Packing and Storage
All parts will be fitted together in workshop. Finished product shall be wrapped by anti-ultraviolet polythene film, then packed in wooden case.
HDPIR
HDPIR is a kind of foaming polymer, with the features of plastic, rubber and cork. The raw materials are isocyanate, polyether, foaming agent, catalyst, flame retardant, etc. After high speed stirring, materials react and foam to cellular structure product, composed of millions of tiny and uniform sealed cells. It provide benefits of low density, low thermal conductivity, low water absorption. The performance is better than timber.
