It is suitable for heat exchange of corrosive media such as chemical and petroleum.
Manufacturing Titanium Heat Exchangers
According to the design and application of the heat exchanger, choose the appropriate titanium grade and specification of titanium. For shell and tube heat exchangers, it is necessary to purchase raw materials such as titanium tubes and titanium plates. For plate heat exchangers, titanium plates are purchased for stamping plates. Wstitanium conducts strict inspections on the purchased titanium materials. The chemical composition of titanium materials is detected by spectral analysis to ensure that they meet the corresponding grade standards. Mechanical performance tests such as tensile tests and hardness tests verify the strength, plasticity and other performance indicators of titanium materials. Ultrasonic flaw detection and radiographic flaw detection are used to check whether there are defects such as cracks and pores inside the titanium materials.
Titanium Plate Machining
According to the design size of the heat exchanger, CNC cutting machines and other equipment are used to cut titanium plates. During cutting, Wstitanium strictly controls the dimensional accuracy to ensure the specifications of the plates. For some parts with complex shapes, high-precision equipment such as laser cutting machines are used for cutting.
Tube Machining
The titanium tube is cut according to the designed length, and the cutting equipment can be a tube cutter. During the cutting process, attention should be paid to controlling the flatness and verticality of the cut end surface to avoid defects such as burrs. For the connection between the titanium tube and the tube sheet of the shell and tube heat exchanger, the titanium tube usually needs to be expanded or flanging. Flaring is to expand the end of the titanium tube so that it can be better connected to the tube sheet. Flanging is to fold the end of the titanium tube to increase the strength and sealing of the connection.
Titanium materials are usually welded by argon arc welding (TIG welding), plasma arc welding, etc. Argon arc welding has the advantages of stable arc, good protection effect, and high weld quality. It is one of the most widely used technologies in titanium heat exchanger welding.
In welding, high-purity argon gas is used as a shielding gas to prevent titanium materials from reacting with oxygen, nitrogen, etc. in the air at high temperatures to ensure the quality of the weld. Welding parameters have an important influence on the quality of the weld, including welding current, welding speed, arc voltage, argon gas flow, etc. Before welding, it is necessary to evaluate the welding process according to factors such as the grade and thickness of the titanium material to determine the appropriate welding process parameters. During welding, these parameters are strictly controlled to ensure that the weld depth and width are uniform, and there are no defects such as pores and cracks.
After welding is completed, the weld is fully inspected. In addition to the appearance inspection, observe whether the weld surface is flat, whether there are defects such as undercuts and pores, non-destructive testing is also required, such as ultrasonic testing and radiographic testing, to detect whether there are defects such as incomplete penetration and slag inclusions inside the weld. For some important welds, mechanical property tests such as tensile tests and bending tests may also be required to verify whether the strength and toughness of the weld meet the requirements.
Assembly
For shell and tube heat exchangers, install the tube bundle into the shell and fix the two ends on the tube sheet. Pay attention to the arrangement and spacing of the tube bundle to ensure that the fluid can flow evenly in the tube side and shell side. Then, install the baffles, heads, pipes, etc., and assemble the components together by welding or flange connection. During assembly, ensure that the installation position of each component is accurate and the seal is good to prevent leakage.
For plate heat exchangers, stack the stamped plates in the design order, install the sealing gaskets, and then clamp the plate group with clamping bolts. Pay attention to the direction of the plates and the installation position of the sealing gaskets to ensure a good seal. At the same time, control the size of the clamping force to avoid deformation of the plates due to excessive clamping force or poor sealing due to insufficient clamping force.
For spiral plate heat exchangers, roll the spiral plate into a spiral channel and install the inlet and outlet pipes and cover plates. During assembly, ensure that the size of the spiral channel is accurate, the connection between the components is firm, and the seal is reliable. When welding spiral plates, special attention should be paid to the quality of the weld to prevent leakage and problems affecting heat transfer performance.
Quality Inspection
After the heat exchanger is assembled, it needs to be pressure tested to check its sealing and strength. The pressure test usually adopts water pressure test or air pressure test, and the test pressure is generally 1.25-1.5 times the design pressure. In addition to the pressure test, the heat exchanger needs to be fully inspected for quality, including appearance inspection, dimension inspection, heat transfer performance test, etc. The appearance inspection mainly checks whether the surface of the heat exchanger is flat, scratched, deformed and other defects. The dimension inspection verifies whether the dimensions of the heat exchanger meet the design requirements. The heat transfer performance test simulates the actual situation and measures the performance indicators such as the heat transfer coefficient of the heat exchanger to ensure that it meets the use requirements.
Applications
Titanium heat exchangers cover almost all major industries such as chemical, energy, marine, food, and pharmaceuticals. They solve the problems that traditional heat exchangers are difficult to overcome under strong corrosion, high temperature, and high pressure conditions, improve efficiency, and reduce maintenance costs.
- Chemical Industry
In the chemical industry, many media are highly corrosive, such as sulfuric acid, hydrochloric acid, nitric acid, etc. Titanium heat exchangers, with their excellent corrosion resistance, can operate stably during the heat exchange process of these corrosive media. For example, in sulfuric acid production equipment, it is used to cool high-temperature sulfuric acid gas and reduce its temperature to a suitable range. At the same time, titanium heat exchangers also play an important role in hydrochloric acid desorption, nitric acid concentration, etc.
- Energy Industry
In petroleum refining and chemical industry, titanium heat exchangers are used for crude oil preheating, heat exchange of fractionation towers, cooling of oil products, etc. For example, in atmospheric and vacuum distillation units, they are used to heat crude oil to a suitable distillation temperature. In catalytic cracking units, they are used to cool the oil and gas after the reaction and separate different products. Titanium heat exchangers can operate stably under high temperature, high pressure and complex media environments.
- Marine Engineering
In the power system of a ship, the cooling water and lubricating oil of the engine need to be cooled and heated to ensure the normal operation of the engine. Titanium heat exchangers are very suitable for heat exchange in ships due to their good resistance to seawater corrosion. Various equipment on offshore platforms, such as oil and gas processing equipment and living facilities, require heat exchangers to achieve heat transfer and temperature control.
- Pharmaceutical Industry
Titanium heat exchangers play an important role in many aspects of drug production. In drug synthesis reactions, the reaction materials need to be heated or cooled to control the reaction rate and reaction process. Titanium heat exchangers can accurately achieve temperature control to ensure that the reaction is carried out under optimal conditions and improve the yield and quality of drugs.
Although titanium heat exchangers have many advantages, there are still some areas that need to be improved. For example, the relatively high cost of titanium materials has limited its wider application to a certain extent. Some types of titanium heat exchangers are still difficult to clean and repair. In the future, with the advancement of titanium smelting technology and the reduction of costs, as well as the continuous innovation of heat exchanger design and manufacturing technology, titanium heat exchangers are expected to be used in more fields and achieve further improvements in performance and economy.
