What is an Explosion-Proof Pipeline Heater<\/strong> https:\/\/8ruiyan.com\/en\/all-air-heaters\/<\/a>? How Does It Prevent Explosions and Handle Oil, Gas, and Dust?<\/strong><\/p>\n\n\n\n

I. Working Principle of Explosion-Proof Pipeline Heaters<\/strong><\/h2>\n\n\n\n

A pipeline heater is an energy-saving device used for preheating substances. Installed upstream of substance processing equipment, it directly heats the substance, enabling cyclic heating at high temperatures, ultimately achieving the goal of energy conservation.<\/p>\n\n\n\n

II. Structure of the Pipeline Heater<\/strong><\/h2>\n\n\n\n

The explosion-proof electric heater consists of a terminal box, electric heating elements (heating tubes), the heater housing, and temperature control instruments and devices. The terminal box includes the junction box and the connection board for the heating tubes.<\/p>\n\n\n\n

The heating element is an alloy resistance heating wire, made of Cr20Ni80. Together with the internal connection conductors, it is housed within a metal tube. The void inside the tube is densely filled with powdered magnesium oxide inorganic insulation filler. The spacing between heating elements themselves and between them and the metal tube exceeds 2 mm. The connection between the internal conductors and the heating element is achieved via crimping or hard brazing.<\/p>\n\n\n\n

The terminal box is a steel structural component. It has 8 fastening bolts (specification: M12\u00d750). The mating surface has a roughness of 3.2 \u03bcm. Cable entry devices utilize a sealed design, with sealing rings made of silicone rubber and nitrile rubber.<\/p>\n\n\n\n

III. Instructions for Using the Pipeline Heater:<\/strong><\/h2>\n\n\n\n
    \n
  1. Must be used in conjunction with a CNG control cabinet<\/strong>\u00a0to achieve interlocked control.<\/li>\n\n\n\n
  2. The operating voltage\u00a0must not exceed 1.0 times the rated voltage<\/strong>. Both the internal and external shells must be effectively grounded.<\/li>\n\n\n\n
  3. Operating environment:<\/strong>\u00a00\u00b0C ~ 40\u00b0C (Note: Original said 340C, assumed typo for 40\u00b0C based on context), free of corrosive gases.<\/li>\n\n\n\n
  4. Periodically inspect<\/strong>\u00a0the surface of the heating tubes. If carbon deposits or fouling are present, they\u00a0must be completely removed<\/strong>\u00a0before use. Additionally,\u00a0inspect the cylinder body and the level of corrosion annually<\/strong>\u00a0to determine if the container or heating tubes need replacement.<\/li>\n\n\n\n
  5. Thoroughly inspect<\/strong>\u00a0the heater itself, along with its associated electrical equipment, instrumentation, control systems, and wiring to confirm they are intact and ready for use.<\/li>\n\n\n\n
  6. Regularly observe<\/strong>\u00a0whether the equipment, electrical systems, instrumentation, and control systems are functioning normally.<\/li>\n\n\n\n
  7. Continuously monitor<\/strong>\u00a0whether the three-phase currents are balanced.<\/li>\n\n\n\n
  8. This equipment can be\u00a0installed indoors<\/strong>. If outdoor installation is necessary,\u00a0provide protection against rain and snow<\/strong>.<\/li>\n\n\n\n
  9. Strictly control<\/strong>\u00a0the heater’s operating temperature\u00a0below 100\u00b0C<\/strong>\u00a0to avoid combustion or explosion risks if the heating temperature exceeds the auto-ignition point of natural gas.<\/li>\n\n\n\n
  10. According to the JB88-85 standard, the\u00a0minimum service life<\/strong>\u00a0of industrial electric heating tubes is specified as 8,760 hours.\u00a0Maintain an adequate stock of spare heating tubes<\/strong>.<\/li>\n<\/ol>\n\n\n\n
