This guide will provide you with comprehensive insights into acetylene gas tanks for sale, their uses, and technical features.
Types and Applications of Acetylene Gas Tanks
| Type of Cylinder | Capacity (cu ft) | Common Uses | Valve Type |
|---|---|---|---|
| MC Steel Cylinder | 10 | Soldering, Brazing, Heating | CGA200 |
| B Steel Cylinder | 40 | Cutting, Welding, Brazing | CGA520 |
| Size 4 Acetylene | 40 | Industrial Applications | CGA510 |
| High-Pressure Cylinder | Varies | Specialized Industrial Uses | Varies |
Understanding Acetylene Gas
Acetylene (C2H2) is a colorless gas that is used widely in welding and cutting due to its high flame temperature. It is produced by the reaction of calcium carbide with water. Due to its flammability, acetylene must be stored in specially designed tanks, which are robust and pressure-rated to ensure safety.
Properties of Acetylene Gas
- Flame Temperature: Acetylene can reach temperatures of approximately 3,500°F (1,900°C) when burned with oxygen.
- Density: Acetylene is lighter than air, which can pose a risk of accumulation in enclosed spaces.
- Storage: Acetylene must be stored in a vertical position to avoid the risk of liquid acetylene escaping.
Buying Acetylene Gas Tanks
When purchasing acetylene gas tanks, consider the following factors:
1. Capacity and Size
The size of the tank you choose will depend on your specific application. For instance, a 10 cu ft MC cylinder is ideal for small tasks, while a 40 cu ft B cylinder is suitable for more extensive projects. Check suppliers like gascylindersource.com and www.airgas.com for available sizes.
2. Safety Features
Look for tanks that are DOT-approved and have safety features such as pressure relief valves. The cylinders should also be equipped with the appropriate valves, such as CGA200 for MC cylinders or CGA520 for B cylinders.
3. Condition of the Tank
New tanks typically come with the latest safety certifications and are less likely to have wear and tear. Suppliers like weldfabulous.com often provide new tanks that meet current regulations.
4. Availability of Refills
Check if your supplier offers refill services. Many distributors, including meritusgas.com, provide convenient refill options for ongoing projects.

Applications of Acetylene Gas Tanks
Acetylene gas tanks are used in various applications across different industries:
1. Welding and Cutting
Acetylene is commonly used in oxy-acetylene welding and cutting processes. The high temperature produced allows for efficient metal fusion and cutting.
2. Brazing and Soldering
The gas is also useful in brazing and soldering applications, where precise heat control is crucial.
3. Heating
Acetylene can provide heat for metal preheating before other processes, making it versatile in manufacturing settings.
4. Industrial Applications
Larger acetylene tanks are essential in industrial environments for applications that require sustained high temperatures.
