Will a Check Valve stop a Flashback?

Let us first understand what a flashback is. A flashback is an uncontrolled flame that recesses back into your oxy-fuel gas equipment, upstream of the location where the gas is designed to mix. In order to have a flashback you must have oxygen and fuel mixed together. Pure oxygen won’t flash back and pure fuel won’t flash back. You need both gases combined in a specific ratio range to have a flashback.

 

What is the difference between A, B and C welding hoses?

When looking to understand the difference between welding hoses, one of the most important things to consider is hose size. Generally, there are three common sizes of hoses – “A”, “B” and “C”. Each hose connection has a matching connecting nut, hose stem and ferrule.

 

What is the difference between gas welding and braze welding?

Gas Welding
The American Welding Society defines gas welding as a group of welding processes wherein coalescence is produced by heating with a gas flame or flames, with or without the application of pressure, and with or without the usage of a filler metal. Gas welding involves the melting of a base metal and a filler metal, if used, by means of the flame produced at the tip of a welding torch. The molten metal from the plate edges and the filler metal, if used, intermix in a common molten pool and upon cooling coalesce to form one continuous piece.

 

What’s the Difference between a Pipeline and Station Regulator?

A station regulator is essentially a pipeline regulator with a “C” hose connection installed on the inlet to prevent the regulator from being used on a pressure source higher than its intended use.

 

Acetylene vs. Alternate Fuel Characteristics

When selecting between acetylene and alternate fuels, there are several factors that need to be evaluated. While cost is certainly a consideration, it’s also important to know the characteristics of each gas. Choosing the wrong fuel gas for your application could end up costing you more in the long run. Here are some important characteristics of both gas types to help you make the best choice.
