Self Pressurized Dewar Flask Cryogenic Liquid Nitrogen Tank Pressure Vessel High Safety

We mainly supply cryogenic equipment and waste tyre pyrolysis oil refining equipment: cryogenic liquid/gas storage tanks (LO2/LN2/LAr/LCO2/LNG/LPG, 5m3-10000L, 0.8-2.2MPa), vacuum-insulated Dewar tanks and flasks, cryogenic CO2 tanks, 40L/50L seamless steel gas cylinders, stainless steel refillable cylinders, CNG vehicle cylinders (65-100L, 30MPa), medical oxygen cylinders (2L/4L/10L), and waste tyre pyrolysis oil refining plants (( fuel oil & carbon black production lines).

For storage tanks, Dewars and the pyrolysis plant, the MOQ is 1 set/piece. For gas cylinders, the MOQ is 100 pieces (CNG vehicle cylinders: 10 pieces). Bulk orders are negotiable; final terms are confirmed in the PI.

Yes. Small items (cylinders, Dewar flasks) support sample shipment. For large tanks and plants, we support factory tours and video inspection before shipment so you can verify the condition and specifications first.

Cryogenic storage tanks are ASME certified and built from carbon steel or 316L stainless steel; high-pressure cylinders comply with standards up to 30MPa design pressure. We provide Trade Assurance (100% protection on product quality and on-time shipment), a 1-year warranty, and inspection support before delivery.

Yes. Customizable items include tank volume (5m3, 15m3, 10000L, etc.), design pressure (1.6-2.2MPa), vertical/horizontal configuration, material (carbon steel/stainless steel), dimensions, instruments and valves, as well as pyrolysis plant capacity and layout according to customer drawings.
