oses between the light and the gas controllers ought to be shading coded; in the UK: red for acetylene, and blue for oxygen. Fittings on the oxygen hose have right-hand strings; while those on the acetylene hose have left-hand threads.The essential capacity of a pipeline equipments controller is to control gas weight. It decreases the high weight of the container put away gas to the working weight of the light, and this will be kept up amid welding.
The controller has two separate gages: a high weight gage for gas in the chamber and a low weight gage for weight of gas encouraged to the light. The measure of gas staying in the barrel can be judged from the high weight gage. The controller, which has a weight changing screw, is utilized to control gas stream rate to the light by setting the outlet gas weight. Note Acetylene is supplied in barrels under a weight of around 15 bar however welding is done with light gas weights normally up to 2 bar.
Fire traps (likewise called flashback arresters) must be fitted into both oxygen and acetylene gas lines to keep a flashback fire from achieving the controllers. Non-return spring-stacked valves can be fitted in the hoses to identify/stop reverse gas stream.Pipeline equipments are very necessery in different types of industries.Along these lines, the valves can be utilized to counteract conditions prompting flashback, however ought to dependably be utilized as a part of conjunction with flashback arresters.
