Steel Specification & Material Control
 

The cylinder body uses high-grade carbon steel specifically engineered for LPG pressure-containing applications. Comprehensive material control includes:

Steel grade verification

Precise thickness measurement

Surface condition inspection

Chemical composition and mechanical properties review

Material certificate review

Heat or batch traceability where required

The selected steel specification corresponds directly to the applicable cylinder standard and forming process.

 

Valve Specification & Configuration
 

Valve configurations are customized based on destination market regulations and customer requirements. Available parameters include:

Valve type and connection thread

Inlet and outlet configurations

Sealing arrangement and valve material

Installation method

Customers can specify an existing valve standard, provide a valve sample, or submit a technical drawing for compatibility review.

 

Wall Thickness, Working & Test Pressure

 

Wall Thickness

Determined by cylinder design, material properties, working pressure, and applicable manufacturing standards. Thickness control is monitored closely during production. Minimum wall thickness is strictly derived from the governing cylinder standard.

Working & Test Pressure

Specified according to the applicable standard and approved product design. These values vary by model, and technical documentation explicitly aligns pressure parameters with target market standards prior to confirmation.

 

Manufacturing Tolerances & Surface Treatment
 

Dimensional tolerances are strictly controlled based on approved drawings and standards, evaluating cylinder diameter, overall height, neck and valve positioning, foot ring alignment, and wall thickness.

 

Surface Treatment Process
Surface Preparation -> Coating -> Curing -> Final Inspection
• Finishes: High-durability paint or powder coating.
• Customization: RAL color matching, specific coating types, surface finish levels, custom logos, product markings, and specialized labeling.
• Quality Check: Inspected thoroughly for coverage, adhesion, visible defects, and exposed metal.

 

Cylinder Components

 

Depending on the model, assemblies may include:

Cylinder body, valve, and neck ring.

Foot ring, carry handle, and valve guard.

Specialized protective components.

 

Testing, Inspection & Third-Party Certification

Rigorous testing guarantees absolute safety and compliance. Typical inspections include:
