Roll On To Roll Off Wharf Area Edible Oil Electric Heat Tracing 25KW

Roll-On-To-Roll-Off Wharf Area Edible Oil Electric Heat Tracing

Roll-On-To-Roll-Off Wharf Area Edible Oil Electric Heat Tracing is a complete set of electric heat trace solution to the roll-on-to-roll-off wharf area edible oil pipeline or tanks.

 

The system uses the current-thermal effect principle to directly convert electrical energy into heat energy. Long line heating possesses good high temperature performance. The heating length can reach more than 2000m with the highest voltage grade 4160VAC, maximum unit heating power up to 5000W/m, the highest temperature withstanding up to 1000℃.

 

The system can be widely used in:

-- Viscosity reduction process for heavy oil;

-- Heavy oil thermal recovery technology: fire flooding, steam flooding, steam huff and puff;

-- Anticondensation and wax plugging removing of oil and gas wells;

-- Heating of in-situ shale oil conversion process.

 

In the field of heavy oil application, compared with the traditional chemical and physical viscosity-reducing mining processes, the system uses clean electric power energy, which is environmentally friendly, convenient to install and use, and has lower investment, operation and maintenance costs.

 

In addition, the system can reduce or even eliminate the use of lean oil or other chemicals and the amount of water used, with very little risk of impact or damage to the environment.

 

 

According to your needs, we can provide the following services:

(1) Design and selection of electric heating system for oil well;

(2) Supporting facilities for electric heating system of oil well;

(3) In-well operation of electric heating system for oil well;

(4) Operation and maintenance of electric heating system of oil well.

 

The oil well heating system takes the integrated mineral insulated heating cable (referred to as the integrated cable) in the cooling and heating sections as the core component, and forms a complete set of electric heating system by supporting electric heating control cabinet, booster transformer and other electrical control systems and installation accessories.

 

 

Integrated cable assembly

 

Structure

 

Composed of an integrated cable, terminal, and tail, the heater is usually prefabricated by the manufacturer to be used directly in the well. For the customers with the corresponding design and processing ability, heater parts can be supported with their own terminal and tail end.

The integrated cable is composed of two parts: cold end cable (commonly known as "cold section") and heating cable (commonly known as "hot section") with the same outer diameter to the cold end. In the manufacturing process, a metal sheath mineral insulated continuous and integrated cable with the same outer diameter is formed.

 

Among them:

-- Cold section: used for power transmission to heating cable, without obvious heating;

-- Hot section: the thermal effect of the current will be used to convert the introduced electric energy into heat energy. The heating is obvious and the temperature is high.

 

The structure consists of cold section and hot section conductors composing of compacted mineral insulation powder and metal sheath.

According to the conductor core number, there are the following three structural forms:

(1) single core, applied to:

-- three-phase electrical circuit (3 cables),

-- Two-phase electrical circuit (2 cables),

-- Single-phase electrical circuit (2 cables);

(2) two cores, used in single-phase or two-phase electrical circuits;

(3) three cores, applied to the three-phase circuit.

 

Material

 

The materials of the integrated structure cable are shown in the following table, in which the metal sheath material should be selected according to the service temperature and the corrosion grade of the surrounding medium, so as to ensure the expected economic service life.
