100mm Stainless Steel Argon Arc Welding Pressure Gauge Bottom Connection Pressure Gauge

Oxygen pressure gauges can be identical to ordinary pressure gauges in terms of structure and material, except that oxygen pressure gauges must be oil free. Because oil entering the oxygen system can easily cause an explosion. When calibrating the oxygen pressure gauge used, it is not allowed to use oil as the working medium, as is the case with ordinary pressure gauges, and the oxygen pressure gauge should be strictly protected from contact with oil contamination during storage. If it is necessary to measure the oxygen pressure using an existing pressure gauge with oil stains, it must be repeatedly cleaned with carbon tetrachloride before use, and carefully checked until there is no oil stains.

In the event of an emergency in which the Bourdon tube bursts through the overflow hole, the internal pressure will be released to the outside through the overflow hole to prevent the glass panel from bursting. Note: In order to maintain the normal performance of the overflow hole, it is necessary to leave a space of at least 10mm behind the table. The overflow hole cannot be modified or plugged. In addition to standard pointers, other pointers are also optional.
