68L TPED CO2 cylinders for carbon dioxide
DSW produces high-quality 4130 CrMo alloy steel CO2 cylinders to meet US DOT and international regulations, using strict standards that comply with their production.
We provide 2L to 80L outstanding-performance CO₂ cylinders suitable for industrial CO₂ and beverage CO₂ applications.
We design, produce, and inspect them according to international standards, using high-strength steel with uniform height, precise engraving, and extended durability.
DSW’s aluminum CO2 cylinders are lightweight, corrosion-resistant, and specially designed for beverage carbonation.
All aluminum CO2 Cylinders have a bare-brushed finish with CGA 320 valves as standard.

Carbon Dioxide Cylinders Sizes
Carbon dioxide gas is used in industries to make chemicals and feedstock.
Carbon dioxide gas is used in many applications, including refrigeration systems, welding processes, water treatment (stabilizing pH), carbonated beverage production, metal casting mold hardness improvement, and soldering agents. Carbon dioxide fire extinguishers that use carbon dioxide-based solutions effectively control electrical fires and those caused by fuels, oils, and solvents.
Guide To CO2 GAS CYLINDERS
Cylinders can be filled with O₂, CO₂, H₂, Ar, He, or N₂. Every cylinder must undergo water pressure testing. The test pressure should exceed its working pressure by at least five times; so, for example, when the working pressure is 15 MPa, the testing pressure may reach 25 Mpa.
All parameters (excluding sheet specifications below), such as package size, price, and more, are symbolic as they depend on other variables; for instance, material pricing varies frequently, and thus we need to negotiate them in detail before finalizing our agreement. Customization options may include body color, words sprayed on valve types/cap types/material types (37Mn, 34CrMo4/QF-2C9, CGA326/ZF-15, etc.), cap color options, and neck rings with internal polishing services, all available as options to customize our offer fully.
CO2 CYLINDER MANUFACTURING
Refillable 20L-80L industrial gas cylinders meet ISO9809-3 and DOT approval. Options available are nitrogen (N2), oxygen (O2), and hydrogen (H2).
