Composite LPG range
Type 4 Composite LPG Cylinders
Reference selections span 6–20 kg nominal LPG, with alternative casing dimensions and project-specific configurations available for review.
Lightweight, corrosion-resistant LPG handling
A non-load-sharing HDPE liner provides gas containment, a fully wrapped glass-fibre composite shell carries the pressure load, and a protective polymer casing integrates the handle and stable base. The translucent pressure vessel allows an approximate LPG level check, subject to lighting and surface condition.
