Whether it is a steam boiler or a hot water boiler, after the boiler is installed, a hydraulic pressure test (that is, water pressure) must be performed. After long distance transportation, loading and unloading, installation, collision and damage are unavoidable. Boiler defects can be found through water pressure tests and corresponding measures can be taken in time to ensure the safe operation of the boiler. The following is an example of the hydraulic pressure test of a fuel gas industrial boiler:
The hydraulic pressure test of oil and gas boilers is generally divided into a hydraulic pressure test and a super-hydraulic test of rated working pressure. The overpressure test pressure of the boiler body is 1.25 times of the rated working pressure of the boiler shell or the rated pressure plus 0.4 MPa.
First, when one of the following conditions is encountered, an overpressure water pressure test is required:
1. Before the newly installed boiler starts trial operation;
2. After the boiler's pressure parts have undergone major transformation or replacement;
3. The oil and gas industrial boiler in operation is carried out every six years (combined with overhaul).
2. When one of the following situations is encountered, a working pressure and water pressure test is required:
1. After large and small repairs or rush repairs, the hydraulic pressure test of the working pressure is performed after the repairs;
2. If the furnace is shut down for more than 30 days, a hydraulic pressure test of the working pressure must be performed before ignition.
The above is the relevant content of the hydraulic pressure test of the fuel gas industry that I share with you. I hope it will be helpful to everyone.
