Reaction and storage equipment: Stainless steel coils of models such as 304 and 316L are often processed into inner walls of reaction vessels, chemical storage tanks, etc. For example, in coastal chemical plants, 316L stainless steel coils are used to make the inner walls of reaction vessels, which can resist corrosion from acidic and alkaline media and have a significantly longer service life than traditional carbon steel; The sewage storage tanks and filtration tanks in sewage treatment equipment also rely on their corrosion resistance to prevent chemical substances in the sewage from corroding the equipment.
Transportation and processing components: Chemical pipelines, valves, pump bodies, and other transportation components are mostly made of stainless steel coils, which can ensure the safe transportation of high-risk chemical media; In environmental engineering, stainless steel coils are used for waste gas treatment towers, sprinkler pipelines, as well as conveyor trough plates, filter screens, etc. for sewage treatment. They can resist corrosive components in sewage and waste gas, and their easy to clean characteristics also facilitate equipment maintenance.
2. Energy engineering equipment
Nuclear power and petroleum equipment: The inner lining of nuclear power equipment is made of stainless steel coils through precision rolling and welding, which can withstand extreme environments and resist corrosion from radioactive substances and coolants; The core components of oil pipelines and refining equipment in the field of petroleum refining can withstand high pressure and corrosive substances such as sulfides in crude oil after being processed with stainless steel coils, ensuring the safety and stability of the refining process.
New energy supporting equipment: The inverter casing and brackets in photovoltaic power plants, as well as the internal structural components of wind power equipment nacelle covers, will be made of stainless steel coils. Its weather resistance can cope with harsh outdoor environments such as sandstorms, rain and snow; The battery pack casing of new energy storage equipment can also be processed with stainless steel coils, which have both rust prevention and protective properties, avoiding the battery from being affected by the external environment.
3. Construction and Engineering Machinery
Core components of construction machinery: Some protective panels and brackets of excavators and loaders are made of stainless steel coils, which can withstand the impact and wear during construction, as well as resist rusting in humid environments on construction sites; The hook connectors and local protective shells of the crane ensure the safety of lifting operations by utilizing their high-strength characteristics.
Auxiliary equipment for construction: partial lining of concrete conveying pipelines and mixing equipment on the construction site, stainless steel coils can resist the wear and moisture erosion of concrete; Temporary construction protective railings and detachable construction platform panels are also commonly made of stainless steel coils, which are sturdy, durable, and easy to disassemble and transport.
4. Rail Transit and Special Engineering Equipment
Rail transit equipment: The structural components of subway vehicles, platform screen door frames, guardrails, etc. are made of high-strength stainless steel coils, which can resist corrosion in underground humid environments while ensuring structural stability; The brake discs, brake calipers and other components of high-speed trains are processed with martensitic stainless steel coils, which have high temperature resistance and wear resistance to cope with the high temperature generated during braking, ensuring driving safety.
Agricultural and ship engineering equipment: Cutting blades for harvesters, pipelines and nozzles for irrigation equipment, and other agricultural engineering equipment. Stainless steel coils can prevent corrosion from soil and pesticides, and their high-strength characteristics ensure the sharpness and durability of the blades; The partial structure, valves, and piping systems of chemical tankers and ocean engineering ships are made of stainless steel coils that can resist strong corrosion from seawater, ensuring the long-term operation of ships in marine environments.
5. Precision engineering and specialized equipment
Precision machine tool equipment: Some precision machine tool bed auxiliary brackets, guide rail covers, etc. are processed with 2mm thick stainless steel coils, which not only ensures structural rigidity, but also facilitates laser cutting and bending forming, reducing the risk of deformation during equipment operation and ensuring processing accuracy; The control panel and casing of machine tools are also commonly made of stainless steel coils, which combine protection and aesthetics.
Medical engineering equipment: The shells of medical carts and disinfection equipment, as well as the shells and internal structural components of CT machines and nuclear magnetic resonance machines, are mostly made of austenitic stainless steel coils. Its non-magnetic properties will not interfere with the device's magnetic field, and the smooth surface is also easy to clean and disinfect; The basic billet of surgical instruments is commonly made of martensitic stainless steel coils, which can obtain high hardness after heat treatment and meet the requirements for the use of surgical instruments.
