Duplex stainless steel has gradually become the preferred material for seawater pipeline systems in nuclear power plants because its corrosion resistance to seawater is better than austenitic stainless...
Thermoplasticity of duplex stainless steel is poor due to the different deformation behaviors of the austenite phase and the ferrite phase. The stress and strain distribution between the two phases during...
4. Pickling and passivation of stainless steel pipelines 4.1 Requirements for pickling passivation By pickling, the oxide scale formed by high-temperature operations such as heat treatment and welding...
2. Rectification of construction Through the close cooperation and analysis of welding technicians, flaw detection personnel in the workshop and quality department, it was finally determined that the...
Abstract: Aiming at the problem of tungsten inclusion during the prefabrication of carbon steel pipes for asphalt tankers and chemical tankers, the argon arc welding process was improved. Firstly, check...
Abstract: Stainless steel pipelines in LNG projects will inevitably be damaged during transportation, hoisting or prefabrication welding. In order to repair and protect stainless steel pipelines...
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...
