The Function and Advantages of the High-Pressure Gas Cylinder Inner Wall Cleaning Machine

The core function of the high-pressure gas cylinder inner wall cleaning machine is to remove oxide scale, rust, oil stains, and impurities from the inner wall, eliminate internal stress, strengthen the inner wall metal, and ensure the cleanliness and safety of the gas cylinder; its core advantages are thorough cleaning, stable quality, high efficiency, environmental protection and safety, adaptability to small diameters, and high automation level. It is a key equipment for gas cylinder manufacturing and regular maintenance.
A. Core Function of the Gas Cylinder Inner Wall Cleaning Machine
Deeply clean the inner wall, eliminate safety hazards
Efficiently remove high-temperature oxide scale, rust, welding slag, stretching residues, oil stains, old coatings from the inner wall, with a cleaning grade stable at Sa2.0–Sa2.5, meeting the safety standards for high-pressure gas cylinders.
360° no-corner cleaning, suitable for ** small diameters (≤30mm) ** gas cylinders, solving the problem of blind areas that cannot be reached by manual cleaning.
Remove impurities to avoid gas pollution, valve blockage, and inner wall corrosion, ensuring the purity of gas filling and the safety of gas use.
Eliminate internal stress, enhance structural strength
During the cleaning process, high-speed projectiles impact the inner wall, eliminating residual internal stress generated during firing, stretching, and closing processes, reducing the risk of deformation and cracking in subsequent use.
The plastic deformation of the inner wall metal layer generates residual compressive stress, significantly enhancing the fatigue resistance and stress corrosion cracking resistance, and prolonging the service life of the gas cylinder.
Optimize the inner wall surface, strengthen anti-corrosion and detection
Form uniform and controllable roughness, enhance the adhesion of inner wall coatings (such as enamel), and increase the durability of anti-corrosion.
Clean the inner wall to facilitate visual or instrument detection of cracks, pits, and corrosion defects, promptly identifying safety hazards and ensuring the compliant operation of the gas cylinder.
Suitable for the entire manufacturing and maintenance process
New cylinder manufacturing: Clean the inner wall impurities after forming, providing a qualified surface for subsequent coating, pressure testing, and filling.
In-use cylinder maintenance: Regularly remove inner wall rust and contaminants, meeting the mandatory requirements of gas cylinder regular inspections, avoiding the risk of over-service.
B. Advantages of the Gas Cylinder Inner Wall Cleaning Machine
Thorough cleaning, stable quality
High-pressure jetting + reciprocating spray gun + 360° rotation of the gas cylinder, full coverage of the inner wall, no missed cleaning, no dead corners, consistent cleaning effect.
Precise control of projectile flow, spray pressure, and cleaning time by PLC, uniform quality for each batch of workpieces, no fluctuations caused by human operation differences.
Suitable for various high-pressure gas cylinders (oxygen cylinders, acetylene cylinders, LNG/CNG cylinders, etc.) with diameters of φ219–426mm and a bottle mouth of ≤30mm, with strong versatility.
Highly efficient automation, significantly increasing production capacity
