What are Stainless Steel-CNG Tanks?

Stainless Steel CNG Tanks, also known as Stainless Steel CNG cylinders (Type I), are all-metal, seamless tanks designed to hold compressed natural gas at high pressures (approximately 150–300 bar / 3000–4350 psi). These tanks are reliable, durable, and widely used in transportation, industrial, and stationary applications

TypeConstructionProperties
Type ISeamless all-steel cylinderEconomical, robust, heavy-duty, high-pressure capacity
Type IISteel liner with composite hoop wrapModerate weight reduction, higher cost
Type IIIThin steel liner, fully composite-wrappedLightweight, impact- and heat-resistant
Type IVPlastic liner, fully wrapped compositeUltra-lightweight, enhanced safety behavior

Our focus is on Stainless Steel-CNG Type I Cylinders, known for their all-metal seamless design and excellent safety track record.
