Pressure vessels are vital across industries, designed to contain gases or liquids under varying pressures. Material selection is critical for safety, efficiency, and longevity.Initially, pressure vessels were riveted steel plates, later replaced by welded steel for improved strength. Technological advancements… Read More »Top Six Materials Used for Pressure Vessel Fabrication
Comprehensive guide for the selection of materials for pressure vessels, ensuring their safety and reliability in various operating conditions.
The manufacture of pressure vessels is a complex production process. Irregularities or deficiencies in any part of the process can have an impact on the quality of pressure vessels.
Therefore, during the manufacturing process, it is crucial to strictly adhere to quality control requirements and fully utilize the role of quality management measures.
The continuous optimization of pressure vessel manufacturing processes, coupled with stringent quality control throughout the production stages, becomes imperative.
This article delves into the key points of pressure vessel manufacturing, focusing on essential aspects such as material quality, component fabrication, welding, and non-destructive testing.
A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. These vessels are integral to various industrial processes and are constructed to withstand the internal pressure exerted by the contained substance. The primary purpose of a pressure vessel is to safely contain and transport substances under conditions of high pressure, temperature, or both.
Thermal stress relief is a critical process in plate rolling, ensuring the reduction of internal stresses and enhancing the material’s stability and durability. Several techniques are employed in this domain, each with its unique benefits and applications. This article delves… Read More »Understanding Various Techniques of Thermal Stress Relief in Plate Rolling
Composite plate pressure vessels are cheaper than pressure vessels of the same specifications made of pure cladding materials. Users often choose the former when the requirements are met. However, the situation is different for manufacturers. On the one hand, composite panels have few specifications and models, and often require outsourcing for composite processing, which prolongs the manufacturing cycle and makes processing and manufacturing difficult.
The pressure of the supercritical CO2 fluid extraction process is generally 8~35Mpa, sometimes higher. In GB1501998 “Steel Pressure Vessels”, the design specifications are unified for pressure vessels with a design pressure of less than 35Mpa. CO2 extraction vessel is high-pressure… Read More »CO2 extraction vessel materials and the top two structural forms
