Oilfield, High-Pressure Natural Gas Anti-Freeze & Anti-Block Solution

At the wellhead, the Explosion-Proof Electric Heater (Wellhead Insulation) is installed in an insulation box to preheat high-water-cut crude oil and associated gas produced from underground, preventing the formation of hydrates, wax deposition, or ice blockage at the wellhead and the initial stage of production and transportation. The preheated medium enters the gathering and transportation pipelines, and the Explosion-Proof Electric Heater (Crude Oil pipeline) compensate for heat loss along the line, maintaining the fluid temperature above the wax point and hydrate formation temperature, thereby reducing the frequency of wax removal and blockage clearing operations.

At the oil gathering station, XGTHERMAL's Конвекционный взрывозащищенный электронагреватель provides safe space heating in hazardous areas such as compressor stations or control rooms, ensuring operational comfort without ignition risks.

Upon entering the integrated processing station, Vacuum Phase-Change Explosion-Proof Electric Heater are used in combination with Explosion-proof Electromagnetic Heater to provide a constant-temperature heat source for multi-stage separators, filters, and pressure regulation & metering devices. This prevents high-pressure natural gas from freezing due to the Joule-Thomson effect during pressure reduction and throttling, while avoiding ice blockage in valves, filters, and downstream urban gas pipeline networks.

At natural gas stations (CNG, LNG, or city gate stations), Explosion-Proof Electric Heater (Natural Gas Pipeline) are installed before and after pressure regulation. Through precise power segmentation and PLC control, the outlet temperature is automatically adjusted according to the inlet pressure and flow rate, achieving "anti-freezing without overheating", improving natural gas utilization efficiency, and extending the service life of downstream equipment. The entire system is designed in accordance with explosion-proof standards such as GB3836 and IEC 60079, with a protection class up to IP65, suitable for high-pressure, high-humidity, and high-corrosion outdoor environments.

Explosion-Proof Electric Heater for Heating Water-Oil-Gas Mixtures

In reservoir development, three-phase mixed fluid (water, crude oil, and natural gas) often exists simultaneously in wellbores and surface pipelines. Fluctuations in temperature and pressure are prone to causing emulsification, gas-liquid stratification, and hydrate formation. The Explosion-proof Electric Heaters provided by XGTHERMAL can be directly installed in pipelines or vessels containing water-cut crude oil, wet gas, and three-phase mixed media. Through convective heat transfer and precise temperature control, the mixed fluid is integrally heated to the process-required temperature range, improving fluidity and supporting subsequent separation processes.

The equipment can be configured with PLC interlocks with temperature and pressure to achieve safe operation under unattended conditions. Once excessive pressure or flow interruption occurs, the system automatically cuts off the heating output to ensure the intrinsic safety of oil and gas fields. This three-phase mixing heating solution is widely applicable to gathering and transportation pipelines, metering skids, compressor unit inlets, and front ends of dehydration units, reducing the construction and maintenance costs of traditional heat sources such as steam and hot water for users.

Crude Oil Sediment Separation & Heating Solution

For high-wax, high-sand, or mechanically contaminated crude oil, XGTHERMAL provides Explosion-proof Oil Storage Tank Electric Heaters and supporting temperature control systems for oil storage tanks and buffer tanks to maintain the fluidity of crude oil in the tanks and accelerate sedimentation and stratification. By controlling the temperature gradient at different heights of the tank bottom and tank wall, water and solid particles sink, and the viscosity of the upper crude oil is reduced, thereby improving dehydration and desanding efficiency and extending the service life of pumps and metering instruments.

This integrated heating and sedimentation solution reduces the investment in steam boiler systems, lowers operation and maintenance costs as well as energy consumption, and provides users with greener and safer crude oil gathering, transportation, and storage methods.
