Double-wall vessels are used to accomodate aggressive liquids, gases and other substances with specific storing, use and disposal requirements. By design the vessel provides consistent tightness control for internal vessel and inter-wall, and also protects soil and ambient air from contamination. Double-wall vessels are construed as pressure vessels. Product bodies are welded steel makes (vessel-in-vessel type). Internal body material is corrosion-proof steel, covering body material is low-alloyed steel.
