A heat tracing method for flue gas pipelines in industries such as power plants, petrochemical, natural gas, finished oil, and crude oil, which is an important component of environmental monitoring systems, is used for environmental sampling and heat tracing.
Corrosion protection sampling composite cable is an important part of the environment protection monitoring system. It is composed of inner core made of a group of corrosion protection resin tubes of high performance, self-regulating heating cable, constant power heating cable and compensating cable, insulation layer and flame retarded polythene (PE) protection jacket. The self-regulating function of self-regulating heating cable can ensure to maintain a certain temperature inside the sampling tube, then samples can be identical with the initial value, and finally ensure that the environment protection monitoring system can continuously and correctly take samples. Different materials can be selected for sampling tube of the corrosion protection composite tube according to composition of the sample and temperature, such as PFA ( polyethylene-fluoridated alkylvinylether), FEP(Fluoridated ethylene-polypropylene co-polymer), PVDF (polyvinyl fluoride), PE (flame retardant polythene) and nylon 610; medium/low/high temperature heating cables can be used; in addition, compensating conductors and power cables can be added as required by the customer.
