With the deepening practice of the circular economy concept, the recycling of used heat exchanger sheets has become a highlight of cost reduction, efficiency improvement, and green transformation in the industrial sector. Through technological innovation and refined management, these metal sheets, once considered "industrial waste," are being given a new lease on life, saving costs for enterprises and injecting new vitality into environmental protection.
Turning Waste into Treasure: Technology Empowers Resource Regeneration
Heat exchangers, as key equipment in industrial production, have core components—metal sheets—that are prone to aging and becoming unusable after long-term use. Traditional processing methods often lead to resource waste. However, now, through professional dismantling, cleaning, and reprocessing technologies, used sheets can be reused. For example, some companies use a "meticulous hammering" process to repair deformed sheets, or reassemble and reconstruct used parts, restoring the functionality of previously discarded sheets and significantly reducing equipment procurement costs.
What types of heat exchangers are worth recycling?
Some used heat exchanger plates are Ti Grade 7, containing palladium (Ti-Pd ~0.2%), and are worth recycling.
Ti Grade 7 used heat exchanger plates mainly come from industries with extremely high corrosion resistance requirements, such as chemical, petroleum, and marine engineering. These heat exchanger plates are typically used to handle media containing chloride ions (such as seawater and chloride solutions) or strong acids and alkalis.
Types of Recycling: When recycling Ti Grade 7 used heat exchanger plates, they mainly fall under the category of post-use waste in titanium alloy scrap. Specifically, this may include:
· Scrapped titanium alloy parts: such as titanium plate heat exchanger plates retired from chemical equipment.
· Titanium equipment: such as titanium plate heat exchangers, titanium alloy heat exchangers, etc.
Industries Receiving Titanium Grade 7 Waste Heat Exchanger Plates
The following industries are the main sources of recycled heat exchanger plates (Titanium Grade 7), and you may find these waste materials there:
· Chemical Industry: Used for handling corrosive chemicals such as acids, alkalis, and salt solutions.
· Petroleum Industry: Used in crude oil processing and oil cooling processes to handle sulfur- and chlorine-containing media.
· Marine Engineering: Used in seawater desalination and heat exchange systems on offshore platforms due to their excellent resistance to seawater corrosion.
· Other Industrial Sectors: Such as the chlor-alkali industry, food and pharmaceutical industries, and other fields with strict requirements for equipment cleanliness and corrosion resistance.
Recycling Precautions
When recycling titanium grade 7 heat exchanger plates, it is important to note their sensitive chemical composition. Strict sorting is necessary to avoid mixing with other grades of titanium alloy waste, ensuring the purity of the recycled material. Professional recycling companies will dismantle, clean, and pre-treat the plates to remove surface contaminants.
