Product Name: Tank Insert for Water Oil Explosion Proof Electric Heating Element Immersion Heaters Model NO.: SL-IM067 Shape: Tubular Form: Heating Wire Material: SUS304, 316, 321,Incoloy800 Type: Flange Tube Heater Certification: ISO9001, CE Transport Package: Carton or Wooden Case Specification: Customized Origin: China HS Code: 851680000 Product Description The explosion-proof flanged immersion heaters from Shenglong Heaters are one of the most widely used solutions for heating fluids and gases. Designed for use in tanks, vessels, and in-line heating, Shenglong's explosion-proof flanged immersion heaters are easy to install and maintain.HI-POT Test1500V/S min cold conditionInsulation resistance20M Ω minLeakage current0.75ma maxPower tolerance+5%,-10%Voltage120V-440VDiameter range1mm to 40mmHeating resistance wire0Cr25Al5,Cr20Ni80 or as custom's requirementAir tubular heater wattage≥ 2w-4w/cm2Water tubular heater wattage≥ 6w-10w/cm2Dies and fin tubular heater≥ 8W-12w/cm2Optional FeaturesExtended terminal boxProvided when necessary to allow for cooler operation of the terminal box. This allows the heating elements to be sealed with epoxy or RTV and for the customer to provide incoming wire with a much lower insulation temperature rating.ASMEThe heater can be supplied in accordance with ASME section VIII Div. 1 U-Part stamped and certified.ThermostatsBulb and capillary pilot duty or load carrying thermostats can be provided to control the heater. The thermostat bulb can be installed in a thermowell to sense process or element sheath temperature.ThermocouplesType J or K thermocouples can be provided to monitor the process or element sheath temperatures. Thermocouples provided with a ceramic wafer head and screw terminals for ease of wiring. Alternate type E or T available.Hermetically sealed element terminationsA ceramic to metal soldered seal can be provided to eliminate the possibility of moisture from entering the heating element.Removable bussingAllows troubleshooting and isolation of a failed heating element.Cross-baffleConstruction utilizes alternating half baffles spaced closely to cause increased flow velocity across the heating elements to allow better heat transfer from the elements to the fluid.Add support rods for flanges with length less than 30"Support rods can be added to shorter heater with high flow to keep the element support spacers in place.Larger heater circuits for greater than 48A per circuitHeavy wall pipe designElement bundles with smaller outside diameter can be provided for any flange size requested.Pickle and PassivateA chemical treatment in nitric acid can be performed to remove free iron from the outer surface of stainless steel for applications sensitive to contaminants.Electro-polishIs a process similar to plating using cathode and anode reactions but material is removed rather than added to the heater surfaces in order to provide a clean and bright finish.Ring and cover weatherproof or corrosion resistant enclosuresHeavy duty pipe and plate construction.Other element sheath and flange materials available.Work shop of immersion heaters:
