I. Petrochemical Industry (Core Application Field)
As the most common industry for pipeline heater applications, it primarily targets the heating of fluids such as high-viscosity media, chemical raw materials, process exhaust gases, and thermal oil
1.Crude oil / Heavy oil / Residual oil transportation heating
Crude oil and heavy oil exhibit a sharp increase in viscosity at low temperatures, which can easily lead to pipeline blockages and excessive loads on pumping systems. Pipeline heaters are connected in series within the transportation pipeline to provide real-time heating and continuous thermal insulation for the oil, ensuring normal long-distance pipeline transportation while preventing freezing in exposed pipelines during winter.
2. Pretreatment and Heating of Chemical Raw Materials
Various organic solvents, acid and alkali solutions, chemical intermediates, resins, coating slurries, and other materials are preheated to the specified process temperature via pipeline heaters before entering reactors, mixers, and distillation columns, ensuring stable chemical reactions, extraction, and distillation processes.
3. Thermal oil circulation system heating
Heat transfer oil is a commonly used thermal medium in chemical plants, and the pipe heater serves to supplement heating and maintain a constant temperature in the main heat transfer oil pipeline, providing a stable heat source for equipment such as reactors, drying rooms, and presses.
4. Pretreatment of Process Tail Gas and Exhaust Gas
The flammable exhaust gases and process waste gases generated in chemical production are preheated before entering incineration or catalytic treatment equipment to reach the reaction ignition temperature, thereby improving waste gas treatment efficiency.
5. Constant temperature control of circulating water and cleaning solutions in chemical engineering
The circulating cooling water and equipment cleaning solution pipelines are thermally insulated to meet the operational requirements of equipment cleaning and unit cooling systems.
II. New Energy Industry (primarily lithium batteries, photovoltaics, and hydrogen energy, with rapidly increasing demand in recent years)
The production of new energy requires extremely high standards for temperature, cleanliness, and inert atmosphere, making pipeline heaters a core supporting equipment
1. Lithium battery industry chain
Heating of electrolyte, binder, and electrode slurry conveying pipelines: reduces medium viscosity, ensures smooth processes for filling, coating, and slurry delivery, and prevents low-temperature caking;
Preheating with protective gases such as nitrogen and argon: The entire lithium battery production process requires inert gases to isolate air. Pipeline heaters are used to warm the air supply pipelines, preventing moisture condensation in the gases while matching the temperature requirements of drying and formation processes;
Supplementary heating for electrode/cell drying hot air ducts: Continuously supply constant-temperature hot air to the drying duct to enhance drying efficiency and product yield.
2. Photovoltaic Industry
The constant temperature heating of the silicon wafer cleaning solution, texturing solution, and process compressed air pipelines ensures temperature stability for processes such as cleaning, etching, and coating of photovoltaic cells.
3. Hydrogen Energy Industry
Hydrogen production feed gas and purified hydrogen pipelines are heated and temperature-controlled to remove moisture, preventing pipeline icing and impurity precipitation, while adapting to hydrogen storage, transportation, and pre-fueling processes.
III. Environmental Protection and Water Treatment Industry
Focusing on three major directions: sewage treatment, exhaust gas purification, and pure water preparation, it is a standard equipment for environmental protection engineering
1. Wastewater treatment
Heating of domestic sewage and industrial wastewater intake pipelines: During low-temperature seasons, excessively low water temperatures can reduce microbial activity in the biochemical tank. The heater raises the intake water temperature to ensure the normal operation of anaerobic and aerobic treatment systems. Additionally, thermal tracing of sludge conveyance pipelines prevents sludge caking and pipeline blockage.
2. VOCs / Odor Emission Control
Before organic waste gas, cooking fumes, and coating exhaust enter the RCO catalytic combustion, RTO regenerative thermal oxidation, or activated carbon desorption equipment, the waste gas is heated to the reaction temperature by a pipeline heater, serving as a critical pre-treatment device for compliant waste gas processing.
3. Pure water / Ultra-pure water, reclaimed water reuse
Reverse Osmosis (RO) and Ultrafiltration (UF) system raw water heating: Low temperatures significantly reduce the water permeation flux of membrane modules. Constant temperature heating can enhance water treatment efficiency and is widely used in electronic, pharmaceutical, and power plant pure water stations.
Ⅳ Power Industry (Thermal Power, Biomass Power, Power Plant Supporting Facilities)
1. Boiler water and steam system heating
Preheat the pipelines for boiler feedwater, condensate, and demineralized water to increase the inlet water temperature, reduce boiler energy consumption, and enhance the thermal efficiency of the power generation unit.
2. Flue Gas Treatment System
Heating of flue gas pipes for denitrification and desulfurization in power plants: Low-temperature flue gas is prone to condensation, which corrodes pipes and catalysts. The heater raises the flue gas temperature to protect the denitrification catalyst and prevent equipment corrosion.
3. Freeze Protection and Constant Temperature for Public Piping
Compressed air for instrumentation, lubricating oil, and fire water pipelines are heated to prevent freezing in outdoor pipelines during winter, ensuring operational integrity and avoiding instrument failure or oil solidification.
Ⅴ. Food and Pharmaceutical Industry (Focus on Hygienic and Dead-End-Free Heating)
304/316L stainless steel sanitary pipeline heaters are commonly used, complying with GMP production standards for food and pharmaceutical industries
1.Food Processing
Juice, dairy products, edible oil, syrup, and seasoning conveying pipelines are maintained at a constant temperature through heating; the hot water pipelines of food sterilization lines and spray cleaning lines are temperature-controlled; and the hot air pipelines for food drying and cooking processes are heated.
2. Pharmaceutical Industry
The pipelines for purified water and water for injection are maintained at a constant temperature; the transportation and heating of medicinal solutions and herbal extracts are ensured; sterile process air and drying hot air are preheated, with complete elimination of secondary contamination throughout the process, meeting the requirements for sterile production.
VI. Textile, Printing and Dyeing, and Papermaking Industries
1. Printing and dyeing textiles
The dyeing solution, printing paste, and fixing agent pipelines are precisely temperature-controlled to ensure uniform fabric coloring and stable fixing effects. The hot air pipelines of the fabric drying and spreading equipment provide continuous heating.
2. Papermaking Industry
The pulp conveying pipeline is heated to improve pulp fluidity; the drying system of the paper machine circulates water and supplements heat in the hot air ducts, enhancing paper formation quality and production speed.
Ⅶ. Metallurgy and Mining Industry
1. Metallurgy and smelting
Preheating of combustion air and blast furnace gas pipelines enhances fuel combustion efficiency and reduces energy consumption; constant temperature heating of cooling oil and lubricating fluids in rolling and heat treatment production lines.
2. Mine Ore Dressing
