Abstract
The method for in-situ application of an insulating composition can be used to restrict heat loss from industrial equipment such as pipes, boilers, heat exchangers, furnaces, tanks, fittings, and other facilities. The method includes spraying a water-based, ceramic-filled, acrylic composition onto external surfaces of operating equipment. Upon contact with the external surface, the composition crystalizes and bonds to pores in the external surface, forming salt spikes in a white solid film.
Claims20
A method for in-situ application of an insulating composition, comprising the steps of:
- a) operating an equipment, the operating of the equipment achieving an equipment external surface temperature ranging from about 100° C. to about 650° C.;
- and
- b) spraying an initial amount of the insulating composition on the external surface of the equipment while the equipment is in operation to form an initial coating composition layer, the composition being a water-based composition including a ceramic compound;
- c) allowing the initial coating composition layer to dry;
- and
- d) spraying an additional amount of the insulating composition on the initial coating composition layer to form one or more additional coating composition layers on the external surface of the equipment, thereby providing an insulation coating on the external surface of the equipment.
A method for in-situ application of an insulating composition, comprising the steps of:
- a) heating an equipment until an external surface of the equipment achieves a temperature ranging from about 100° C. to about 650° C.;
- and
- b) spraying the insulating composition on the external surface of the equipment using a texture sprayer, the composition being selected from HPC® and HPC®-HT
- c) allowing the coating composition to dry to provide an insulation coating on the external surface of the equipment.
