Product Description

1.Product Introduction of Oil Tank Electric Heating Rod

The explosion-proof electric heating rod for oil tank (hereinafter referred to as the electric heating rod) is designed and manufactured for the electric heating and heat tracing for oil tanks such as storage tank.  For a long time, steam or hot water are mainly used as heat medium for the coil heater to be used for tank heating.  This heater may generate problems such as high accident rate, difficulty in maintenance and repair and high energy consumption.  With the development of enterprises, some departments that used to have sufficient steam sources have begun to be restricted by heat sources. The problem of heat insulation has been plaguing such users. The electric heating rods are developed for solving these problems.  Over the years, the use of various oilfield production plants, oil pumping stations, oil refineries, oil depots, offshore oil platforms, pharmaceutical plants and other places have verified the advanced technical performance and good economic benefits of this product.

 

2.Properties of Oil Tank Electric Heating Rod

1.  The electric heating rod uses the mineral insulation (MI) heating cable developed by PICM as the heating element.


2.  The electric heating rod has a solid structure, high flexural strength, compactness, sealing and explosion-proof, and meets the requirements for heating and heat tracing of various types of storage tanks for petroleum and its products with an explosion-proof grade dIIB T1~T6.


3.  The electric heating rod heats uniformly, low surface heat load, reliable operation and long service life, no reactive power loss, high thermal efficiency, easy operation and maintenance and no daily maintenance required.


4.  The electric heating rod has good corrosion resistance to crude oil and its finished products.

4.working principle and structure of Oil Tank Electric Heating Rod

1.  working principle

The electric heating rod adopts a mineral insulated (MI) heating cable as heating element. The inner cavity of the rod can rapidly conduct heat that are fully transmitted to the rod body and released to the medium through the outer surface of the rod, and the electric energy is all converted into heat energy with a high heat transfer efficiency.

Note: DRB--L type is a special structure of DRB type electric heating rod, which is specially designed for small oil tanks already in use. It can be installed in tank man hole without cleaning the inside or re-opening a new hole.  The heating part is in the lower horizontal section while the vertical part is only the lead-out line section. The joint flange is arranged at the upper end of the vertical section, and the electrical wiring can be adjusted in a suitable direction and position.
