The pressure bearing capacity of steel pipes is an important indicator for evaluating their ability to withstand pressure in industrial and construction applications. This capacity directly...

Abstract This paper conducts an in-depth analysis and discussion on the tungsten inclusion issue in argon arc welding of carbon steel pipes and proposes corresponding process improvement...

The five types of boiler tube failures are caused by wear, corrosion, thermal fatigue, leakages at welding parts, and incorrect steel usage. 1. Wear Wear causes the boiler tube to thin...

Compared to mechanical equipment, severe wear, vibration, significant fatigue, and other problems don’t occur in boiler tubes. However, accidents occur due to the...

With the development of urban water supply pipelines, the requirements for urban water supply pipeline materials are becoming increasingly stringent. Not only must the pressure-bearing capacity meet...

The municipal water supply system is the lifeline of the city and is crucial to maintaining normal social life, social order, and public safety. The urban water supply pipeline must meet...

2.1 Remaining defects in tube blanks 2.1.1 Analysis of causes of residual defects in tube blanks The composition and structure of the billet will segregate in the casting process, and the hot-rolled tube...

Stainless steel pipes have long been a crucial component in the aviation industry, providing durability, strength, and resistance to corrosion. Without them, the aviation industry would not be able to...

1.1 Carbon steel heat exchanger tubes The SA-556Gr.C2 tube is a seamless cold-drawn carbon steel tube commonly used in heaters and is widely used in high-pressure heaters. Although the corrosion resistance...

The heat exchanger tube is the main part of the high-pressure heater tube bundle. The selection of the tube material is directly related to the operating performance and reliability of the high-pressure...

The high-pressure heat exchanger tube is responsible for the heat exchange between the heating steam and the boiler feed water and also withstands the high pressure of the boiler feed water. If the material...

2. Experimental results and analysis 2.1 Metallographic analysis Using JEM-2800F focused ion beam-electron beam double-beam electron microscope and energy spectrometer made by FEI Instruments Co., Ltd.,...
