2.2 The effect of normalizing temperature on the phase and structure of bainite steel pipes Figure 2 is the Xrd diffraction pattern of the bainite steel pipe heated and normalized at different temperatures...

In order to study the effect of normalizing temperature on the microstructure and properties of the newly developed high-impact bainite steel pipes, tensile and impact tests were used to test the mechanical...

As the core part of the high-pressure heater, the heat exchanger tube is directly related to the subsequent operation of the high-pressure heater. It can be seen from the analysis that the pressure of...

A common failure of high-pressure heaters is leakage. The reasons for the leakage of heat exchange tubes are complex and have a lot to do with design, manufacture and operation. 1.1 Carbon steel...

1.1 Carbon steel pipes SA-556Gr.C2 carbon steel heat exchanger tubes have been widely used in high-pressure heat exchanger tubes, and the processing technology is relatively mature. There is no problem...

The heat exchanger tube of the high-pressure heater bears high pressure of the water supply. Therefore, when materials are selected, the mechanical properties of the heat exchanger tube are one of the...

The high-pressure heater is the key device in the heat recovery system of the thermal power unit, and plays an important role in improving the thermal efficiency of the unit. In the heat recovery system,...

2.2 Sealing tests of piping systems 1) Testing equipment For the same pressure test pipeline, at least two pressure gauges or recorders that have been calibrated within 6 months must be prepared, and...

2.1 Installation of carbon steel pipes and their accessories 1) Installation of pipelines Before installing the pipe, it is necessary to confirm the reference coordinates of the pipe. The basic installation...

There are many hidden dangers to quality in the construction of the ship piping system, and the hidden dangers can only be discovered when the equipment is used in the later stage. At this time, changing...

1.1 Research background Urban gas pipelines are divided into outdoor pipelines and indoor pipelines. A comparative analysis and research on urban outdoor buried gas pipelines are carried out in this article....

Bending will occur for seamless steel pipes, straight seam welded steel pipes, forged steel pipes, precision steel pipes, high-precision steel pipes, and other steel pipes to varying degrees in the longitudinal...
