WS Purge cylinder

A purge cylinder is a container or cylinder used in various industrial processes to remove or displace undesirable substances or gases from a system or environment. The specific use and design of a purge cylinder can vary depending on the application.

Common uses of Purge Cylinders:
1. Welding: In welding applications, a purge cylinder is often used to introduce an inert gas, such as argon orhelium, into the welding area. This inert gas displaces oxygen and other contaminants, preventing oxidation and ensuring a clean and high-quality weld.
2. Air Purging: Purge cylinders can be used to purge air or other unwanted gases from pipelines or containersbefore filling them with a different gas or substance. This is common in the oil and gas industry and chemical manufacturing.
3. Purging in Laboratory Settings: In laboratory settings, purge cylinders may be used to create controlled environments with specific gas compositions for experiments, testing, or research.
4. Environmental Remediation: Purge cylinders can be used in environmental remediation efforts to remove or control the release of harmful gases or contaminants from soil, groundwater, or storage tanks.

The specific design and operation of a purge cylinder can vary based on its intended application. They often feature valves and connections for controlling the flow of gas into or out of the system. Purging is essential in situations where the presence of unwanted gases or contaminants could compromise the quality or safety of a process or product.

Key features of WS Purge cylinder:
The WS Gas Cylinder is available for pipes from 145 mm to 1000 mm diameter. This tool has two heat-resistant sealing lips, being heat-resistant to 280°C for up to one hour. The tool has an extremely short purge time of only 2½ minutes for all dimensions, a feature that no other purge tools provide. The flowrate is 10% of the internal pipe diameter, and 20% if welding titanium. When welding thin-walled pipes with only a few elbows, it is recommended to use the WS Gas Cylinder, fitted with a pull ball if necessary.

The difference between the WS and the WS Plus is in the design and heat resistant material of the sealing lips. By changing the lips, e.g. the sealing lips on a 265 mm WS can be replaced with 12" lips, it is possible to weld three different pipe diameters with the same cylinder.

The two tools overlap each other. The choice of product depends on the particular welding application. Factors to consider are the internal diameter, the number and geometry of the bends, the distance the tool is to be pulled, the wall thickness, any pre-heat, and etc. Only then can a decision be made.

We also have tailor-made options available as per the request from the customers. For more info Contact Mehta Sanghvi on 9820127614 / response@weldingaccessoriesindia.com
