How to weld leak equipment

The leakage of some industrial products cannot be ignored and must be dealt with in time.

The plugging of equipment with pressure, oil or toxic substances is a special welding under abnormal working conditions.

It is different from normal welding specifications and places great emphasis on safety during operation.

Safe construction measures to prevent accidents must be formulated before welding.

Therefore, before and during welding construction, the following points must be done:

First, safe pressure relief,before welding to plug the leak, it must be determined whether the pressure of the equipment to be welded will constitute personal injury. Or under the influence of the welding heat source, the equipment has a safe pressure relief channel (such as a safety valve installed), etc.

Second, temperature control. Before welding, all cooling measures for fire prevention and explosion protection must be done. During welding, welders must perform welding in strict accordance with the minimum and minimum heat input specified in the process documents, and safety cooling measures must be implemented while welding to prevent fire or explosion.

Third, anti-poisoning. When sealing and welding containers or pipes containing toxic substances, timely ventilation of leaked toxic gases and timely supply of fresh air must be done. At the same time, it is necessary to do a good job in the pollution isolation of the outflow of toxic substances.
