What are the materials used for sealing

Sealing materials are divided into: High temperature electric heating tubes are sealed with silicone oil, which can withstand high temperatures of 700 ℃. The disadvantage is that it cannot completely prevent liquid and moisture from infiltrating. When using electric heating tubes at medium and low temperatures, silicone sealing is used to prevent liquid from seeping into the tube from the terminal port. The disadvantage is that it can only withstand working temperatures of 220 ℃ and instantaneous temperatures of 250 ℃. When using electric heating tubes at low temperatures, epoxy sealing is used to prevent moisture and liquid from infiltrating. The disadvantage is that it can only withstand working temperatures of 150 ℃ and instantaneous temperatures of 185 ℃.

Due to process factors, the double headed electric heating tube is divided into two ends, each with a 5cm non heating zone. If it is necessary to extend the non heating zone, please inform us before customization. If the wattage density is high, finned fins can be added to increase the heat dissipation effect.

The tube wiring method is divided into two types: Y-△ type wiring belongs to three-phase voltage, series and parallel wiring belongs to single-phase voltage. When wiring, please make sure to choose suitable heat-resistant wires according to the temperature of the wiring area, and lock the terminals to avoid short circuits, which may cause machine leakage and damage to the heating tube.

Copper pipes and SUS304 # 316 pipes are generally used for neutral environments in acidic and alkaline environments, Incoloy nickel alloy pipes are used for weak acidic and weak alkaline environments, Ti titanium alloy pipes are used for moderate acidic and alkaline environments, quartz, Teflon PTFE pipes and Incoloy nickel alloy pipes are used for strong acidic and strong alkaline environments, SUS316 # pipes are used for 900 ℃ environments, SUS304 # pipes are used for 700 ℃ environments, Ti titanium alloy pipes are used for 650 ℃ environments, Cu copper pipes are used for 300 ℃ environments, and Teflon PTFE pipes are used for environments below 110 ℃. Due to the wide variety of heated gases and liquids, as well as the diverse range of applications, please consult with professionals familiar with chemical properties before use.
