material:carbon steel, stainless steel size:3″、5″、6″、8″、10″、12″、14″、16″、18″or bigger Pressure degree:150、3001b ANSIB16.5/HG20592-97 Heating component Material:carbon steel, stainless steel and INCOLOY Watt density:1、2.3、3.5、7、11 W/cm2 Tube Dia.: 8、10、12、16、20mm(Usually tube Dia. is 12 mm) Others Immerging length 3m While the temperature is high, there is heat-dispelling area ixnside of juction box Junction box Dampp-roof Explosion-proof ,Damp-proof Selection and direction The choice for parameter of the heater is according to technics terms, for example: flange, material of heater component, watt density. Reasonable choice not only could save the cost but also prolong the using life of the heater. Following guide is convenient for the users to choose heater, while the last conformation need the calculation of the engineers. The choice of the heaters lie on following factor: 1. The density, viscosity, specific heat and causticity for heated medium 2. Medium pollution of the heaters component 3.The anticorrosive and anti-oxidation of the heater component jackets 4. The watt density of the heater component surface, that is power ratings for unit area. 5. The highest surface temperature of the heater component, which is lie on the following items 1~4 |
