Carbon steel gas storage tanks are pressure vessels welded from carbon steel plates. They are used to store compressed air (or inert gas) and serve as pressure stabilizers, buffers, and cool condensed water in pneumatic systems.
Product features
1. High Strength and Low Cost: Carbon steel (Q235B/345R) offers high compressive strength and costs only 1/3 to 1/2 of stainless steel tanks.
2. Large Capacity Options: Covers volumes from 0.3 to 100 m³ (standard pressure 0.8 to 1.5 MPa), meeting the needs of systems of varying sizes.
3. Long Life: ≥15 years under standard corrosion protection (inner epoxy coating + outer anti-rust paint).
4. Simple Maintenance: The structure has no moving parts, requiring only regular drainage and corrosion inspection.

Applications
1. Manufacturing: Pressure stabilization of pneumatic production lines (automotive assembly, injection molding machines), air supply buffering for sandblasting equipment.
2. Energy/Chemical: Instrument air storage, valve pneumatic control, and natural gas pressure regulating station buffering.
3. Medical/Food: Oil-free systems only (food-grade coating required for interior surfaces), such as air supply for aseptic packaging equipment.
4. Environmental Engineering: Sewage treatment aeration systems, pressure stabilization of pneumatic valve groups.
FAQ
Q1: Why is manual draining necessary daily?
• The air produced by the air compressor contains a large amount of water vapor. After the tank cools down, 60% of the liquid water settles at the bottom of the tank.
• Excessive water accumulation will accelerate tank corrosion and deteriorate downstream air quality.
Q2: Can a dryer be used as a replacement?
• No! It only removes liquid water, not gaseous water vapor (dew point). A refrigerated dryer/adsorption dryer is required to obtain dry air.
Q3: Will carbon steel tanks rust and contaminate the air?
• An epoxy resin coating (thickness ≥ 150μm) is sprayed on the interior to isolate the gas from the metal.
• Regularly inspect the coating integrity (endoscopic inspection every two years) and repair any damage promptly.
Q4: What is the appropriate volume?
• Empirical formula: Gas tank volume (m³) = Compressor discharge (m³/min) × 0.3-0.5
Q5: Do the safety valve and pressure gauge need to be inspected regularly?
• Mandatory requirement: Safety valves must be calibrated annually (according to TSG 21-2016, "Regulations on Safety Technical Supervision of Stationary Pressure Vessels").
• Pressure gauges must be calibrated every six months to ensure accurate indication.
