  • 4 Key Properties of Boiler Quality PlateBoiler quality plate is a subfamily of steel alloys designated for the manufacture of pressure vessels and pipelines. There is an extensive range of specifications and grades suitable for use in both on- and offshore facilities. Natural gas extraction. Petroleum refining. Che...

  • Large diameter seamless tube structure and its chemical activity analysis The corrosion caused by the electrochemical action of large diameter seamless pipe in contact with the surrounding electrolyte is called electrochemical corrosion. The so-called electrochemical action is the role of generating electric current in the process of chemical reaction. This kind of corrosion due to electric curren...

  • Differences between Steel Tube and Steel Pipe While appearing to be interchangeable, steel tube and steel pipe have different industrial purposes and applications. Understanding the differences between the two can ensure you select the right steel product for your application needs. Tube and pipe are manufactured in both carbon steel and stainless steel. The significant differences when considerin...

  • 1. When the newly installed boiler is put into operation. ,2. When a boiler that has been out of service for more than one year resumes operation. ...3. After major repairs or replacements of boiler transformation and pressure-bearing components, if the number of replacement pipes for the water wall exceeds 50%, the superheater, reheater, economizer and other components are replaced in groups, and...

  • 1. After the boiler is installed, the pressure-bearing parts must undergo a hydraulic test. ...2. After the boiler has been overhauled or repaired or the local heating surface has been overhauled, a conventional hydraulic test must be carried out, and the test pressure is equal to the maximum allowable working pressure of the boiler. The water pressure test should be presided over by the maintenan...

  • Boiler hydraulic test is a test of strength and tightness with pressurized water after the boiler is assembled.
