Tube Sheet
Processing Technology Of Titanium Tube Sheet
1. Melting And Ingots: Titanium tube manufacturing begins with vacuum melting of high-purity titanium raw materials (such as vacuum induction melting or arc melting) to remove impurities, and then liquid titanium is cast through ingots to form titanium ingots, and the cooling rate needs to be controlled to avoid cracks and porosity.
2. Rolling Process: divided into two types: cold rolling and hot rolling.
3. Cold Rolling: After removing the oxide scale by pickling, it is made into a high-precision, thin-walled titanium plate (thickness can be up to 0.18mm), which needs to be annealed to relieve stress.
4. Hot Rolling: continuous casting slab is used as raw material, and is coiled into coils after heating, high-pressure water descaling, rough rolling and finishing rolling, which is suitable for use in the pipe industry.
5. Explosion Welding: used for titanium/steel composite tube sheet, through the explosion welding combination of multi-layered titanium plate and base steel plate, it has both the corrosion resistance of titanium and the strength of steel, and is suitable for large-scale equipment such as nuclear reactor tube sheet.
6. Intelligent Welding: For example, ultra-long titanium alloy coiled tubing adopts automatic adaptive molding and deep penetration stable welding technology to achieve single-sided welding and double-sided forming, and improve efficiency and weld quality.
7. Surface Treatment And Finishing
Including polishing and pickling to remove impurities and improve corrosion resistance; Finishing processes such as trimming, leveling, slitting, etc., to ensure dimensional accuracy.
Heat treatments (e.g. annealing) are used to eliminate cold work hardening and optimize mechanical properties.
8.3D Printing: Explore the rapid manufacturing and personalization of titanium tubes, which can be formed layer by layer with titanium alloy powder, reducing costs and cycle times.
9. Spinning Method: used for the manufacture of special shape titanium tubes, such as propellers and other special-shaped parts.
Application Field Of Titanium Tubular Sheet
1. Aerospace: used for aircraft fuselage, engine parts (such as turbine blades), spacecraft fuel systems, etc., due to light weight (density of 60% of steel), high temperature resistance and fatigue resistance to improve load capacity and fuel efficiency.
2. Chemical & Energy:
Chemical equipment (reactors, acid/alkali pipelines) relies on titanium's corrosion resistance;
In the field of nuclear energy, it is used for nuclear fuel elements and coolant pipes, and titanium alloys can withstand high temperatures, high pressures and radiation environments.
3. Medical Devices: such as artificial joints and dental implants, due to their biocompatibility and resistance to body fluid corrosion.
4. Marine Engineering: used in seawater desalination equipment and offshore oil exploitation pipelines, with remarkable seawater corrosion resistance.
5. New Energy:
solar photovoltaic panel brackets and nuclear power equipment;
Titanium alloy coiled tubing is used for drilling 10,000 meters of deep wells, replacing steel pipes to break through the depth limit (up to 12,000 meters).
6. High-End Manufacturing And Consumption Field:
Automotive lightweight parts, sports equipment (golf clubs, bicycle racks)
High-rise structural supports in the construction sector.
7. Special Scene Application
Food & Pharmaceutical: Used in aseptic conveying pipelines and brewing equipment to avoid contamination by metal ions.
Electronic Equipment: As a thermally conductive/electrically conductive component, it is used in heat dissipation systems and precision instruments.
