High-pressure gas cylinder outer wall shot blasting cleaning machine

High-pressure gas cylinder outer wall shot blasting cleaning machine
The core function of the high-pressure gas cylinder outer wall shot blasting cleaning machine is to thoroughly remove rust and oxide scale, enhance the surface, uniformly roughen it, and eliminate internal stress. The core advantages are high efficiency, stable quality, environmental protection and safety, low comprehensive cost, and strong automation. It is a key equipment for gas cylinder manufacturing and maintenance.
A. Core function of the gas cylinder outer wall shot blasting machine
Thorough surface cleaning
Strongly remove oxidation scale, rust, welding slag, oil stains, old coatings on the outer wall. The cleaning grade is stable at Sa2.5 level, meeting the safety standards for high-pressure gas cylinders.
360° full coverage, no dead corners, no missed cleaning, suitable for various high-pressure gas cylinders such as oxygen cylinders, acetylene cylinders, and liquefied gas cylinders.
Surface strengthening and performance improvement
High-speed shot blasting impact causes plastic deformation of the surface layer metal, generating residual compressive stress, significantly improving fatigue strength, anti-tensile stress corrosion ability, and extending the service life of the gas cylinder.
Eliminate internal stress generated by welding and rolling, reducing the risk of deformation and cracking during subsequent processing or use.
Optimize the coating base
Form uniform and controllable roughness (usually 25–75 μm), significantly improving the adhesion of the coating, avoiding peeling and detachment after coating, and enhancing the corrosion resistance and durability.
Quality inspection assistance
The cleaned surface is unobstructed, facilitating visual or instrument detection of cracks, pits, and corrosion defects, ensuring the safe operation of the gas cylinder.
B. Core advantages of the gas cylinder outer wall shot blasting machine
Efficient and energy-saving, outstanding production capacity
Automated continuous operation, the gas cylinder rotates while advancing, each machine can process 30–50 pieces per hour, the efficiency is more than 20 times that of manual grinding, and it can operate 24 hours continuously.
Shot blasting cleaning + shot blasting cycle recycling + shot blasting reuse, energy consumption reduced by 20%–30%, abrasive reuse, and comprehensive cost reduction.
Quality stable and controllable
PLC precisely controls the shot blasting flow rate, throwing speed, and processing time, each batch of workpieces has consistent effect, without the quality fluctuations caused by human operation differences.
Uniform surface roughness, strong coating adhesion, very low rework rate.
Green and environmentally friendly, safe and compliant
Physical cleaning, no chemical wastewater, acid mist, or waste residue pollution; equipped with efficient bag dust collection, dust emissions meet standards, improving the working environment.
Closed shot blasting chamber + wear-resistant guard plates, reducing noise and wear, ensuring operational safety.
High automation level, low labor costs
From loading to shot blasting to discharging, fully automatic, one person can monitor multiple machines, significantly reducing the demand for labor and management costs.
Can seamlessly connect with the coating line, reducing logistics transfer and improving production continuity.
Compact structure, easy maintenance
No pit installation, saving construction costs; modular design, easy maintenance, easy replacement of wear parts, low maintenance costs.
Suitable for φ219–426mm different diameter gas cylinders, with strong universality.
C. Summary
The gas cylinder outer wall shot blasting machine is not only a cleaning tool but also a quality and safety guarantee equipment. Through the four functions of cleaning, strengthening, roughening, and stress elimination, it solves the core pain points of surface treatment for high-pressure gas cylinders. At the same time, it is superior to traditional processes in terms of efficiency, quality, environmental protection, and cost. It is a standard equipment for high-pressure gas cylinder manufacturing and maintenance.
