Cold / Cryogenic Pipe & Equipment
Cold/Cyrogenic processes involve gas processing, refining, petrochemical and specialty chemical industries and include critical processes such as ethylene, glycol brine, refrigerants, LNG, LOX, and LN2.
In these processes, water vapor can enter permeable insulations and condense, which causes a build-up of water and/or ice, drastically lowering performance. When this type of insulation corruption occurs, thermal efficiency is lost and energy consumption increases dramatically. Increasing energy consumption due to a loss of thermal efficiency can be avoided by using the appropriate insulating materials and system.
FOAMGLAS® ONETM insulation is impermeable to water and water vapor. As such, the material provides constant thermal efficiency throughout the life of the system, greatly reducing long-term energy consumption. It is a high-performance, long-lasting solution for cold and cryogenic processes.
FOAMGLAS® insulation is also noncombustible – an important safety feature for cold and cryogenic processes in case of hydrocarbon fires.
Consult Pittsburgh Corning's Technical Services for guide specifications covering the latest information about design, installation and maintenance of FOAMGLAS® insulation systems.
Typical Configuration for Service Temperatures from below ambient to -50°C (-58°F):
A single or double layer system of prefabricated insulation shells (PSH), segments (PSG) and shapes is generally sufficient for this temperature range.
Two layer systems shall be applied with staggered joints.
Joints shall be sealed with a PITTSEAL® sealant appropriate for the application.
Typical Configuration for Service Temperatures from -50°C to -180°C (-58°F to -292°F):
A double layer system of prefabricated shells (PSH), segments (PSG) and shapes is generally sufficient for this temperature range.
The insulation layers shall be designed / manufactured so that the interface temperature of the two layers is not lower than ‑50°C (-58°F).
- System shall be applied with staggered joints.
Outer layer joints shall be sealed with a PITTSEAL® sealant appropriate for this application.
Typical Configuration for Service Temperatures below -180°C (-292°F):
A triple layer system of prefabricated shells (PSH), segments (PSG) and shapes is generally sufficient for this temperature range.
- For small pipe diameters, a double layer system may be sufficient depending upon the weather or service conditions.
- Many designers and national regulations impose liquid oxygen compatibility requirements to all applications at temperatures below -180°C (-292°F).
