Why does metal cutting and welding require oxygen?
The core function of oxygen in metal processing is to assist combustion and oxidation.
Cutting (especially oxyacetylene cutting and plasma cutting assistance): Oxygen is the key. The process is divided into two steps:
Flames (such as acetylene flames) first heat the metal to its ignition point (approximately 870 ° C for steel).
Then, a high-speed pure oxygen stream is sprayed onto the heating point, and the pure oxygen undergoes a violent oxidation reaction (combustion) with the high-temperature metal, generating metal oxides (slag) and releasing a large amount of heat. This high-speed oxygen flow simultaneously blows away the slag, forming a slit and achieving cutting.
The purity and pressure of oxygen directly determine the cutting speed and effectiveness. The higher the purity, the more intense the oxidation reaction, the faster the cutting speed, and the neater the incision.
Welding (such as oxyacetylene welding): Oxygen is mixed with combustible gases (such as acetylene, propane) and burned, producing a high-temperature flame to melt the base material and welding material. Oxygen is a necessary source of high-temperature heat here.
To understand the advantages of VPSA, the first thing to look at is what it replaces:
* Bottled oxygen (oxygen cylinder):
High cost: The price of oxygen itself plus frequent transportation, loading and unloading, and rental costs.
Low efficiency: requires frequent replacement of gas cylinders, interrupting the production process.
Safety hazards: High pressure gas cylinders pose risks during storage and transportation and require strict management.
Purity fluctuation: When the pressure of the last bottle of gas is insufficient, the purity and pressure will decrease, affecting the quality of cutting/welding.
*Liquid oxygen (LOX):
Evaporation loss: Even if the storage tank is not used, it will naturally evaporate and lose a portion of oxygen (about 0.4% -0.6%) every day, resulting in waste.
Supply dependence: requires regular delivery of liquid oxygen tankers, affected by supply chain and weather conditions.
Initial investment: expensive vacuum insulated storage tanks and vaporization equipment need to be built.
How can VPSA oxygen generator/plant solve these problems?
VPSA (Vacuum Pressure Swing Adsorption) technology directly separates oxygen from air. The main components of air are 78% nitrogen and 21% oxygen. The core of VPSA equipment is to use molecular sieves (a material with strong adsorption ability for nitrogen) to adsorb nitrogen and obtain high concentration oxygen.
The workflow can be briefly summarized as follows:
Compressed air → Pre treatment (water removal, oil removal, dust removal) → Pressure swing adsorption tower (nitrogen is adsorbed, oxygen passes through) → Obtain finished oxygen (93% ± 3%) → Transport to the point of use after pressurization.
1. Significantly reduce the cost of oxygen usage (core advantage)
Once the VPSA oxygen concentrator is put into operation, its raw material is free air, and the main cost comes from electricity (driving the air compressor and vacuum pump).
For large to medium-sized metal processing plants, shipyards, steel structure enterprises and other oxygen consuming enterprises, the cost of oxygen produced by their own VPSA is only 20% -40% of bottled oxygen.
The return period for investing in a VPSA device is usually very short (1-3 years), followed by almost "free" oxygen, and the long-term economic benefits are extremely significant.
2, Ensure stable and continuous oxygen supply
Ready to use: VPSA oxygen concentrators can produce oxygen 24 hours a day without interruption and deliver it directly to each workstation through pipelines.
Stable pressure: The output pressure and purity are very stable, ensuring consistent quality during cutting and welding processes. The cutting section is smoother and the welding quality is higher.
Never "run out of gas": eliminates delays in waiting for gas cylinder delivery, makes the production process smoother, and improves overall production efficiency.
3, Moderate purity, fully meeting the process requirements
The purity of oxygen produced by VPSA oxygen concentrators is usually between 90% and 95%.
This purity range perfectly matches the requirements of metal cutting (such as CNC flame/plasma cutting) and welding (such as oxygen acetylene welding). Excessive purity (such as 99.5% or higher) is a waste for these applications, and VPSA provides the best balance between effectiveness and cost in terms of purity.
4, Enhance security and convenience
Eliminating the risk of high pressure: The pressure of pipeline transportation is much lower than the pressure inside the oxygen cylinder (usually below 15 bar), greatly reducing the risk of leakage and explosion.
Easy management: No need to manage, transport, and store a large number of high-pressure gas cylinders, saving space and manpower, and making the workshop environment safer and cleaner.
Ready to use: Just like using tap water, it's as convenient as opening the valve to get oxygen.
summary
For the metal processing industry that requires a large amount of oxygen consumption, using VPSA oxygen concentrators is not an "option", but a key cost reducing and efficiency enhancing facility.
