High Temperature Pressure Vessels

High-temperature vessel plates are special steel plates used to manufacture vessels and equipment that can withstand high-temperature and high-pressure conditions. These containers are commonly used in the petroleum, chemical, energy and other industries to store and handle high-temperature fluids, gases or chemicals.

Here are some key points about high temperature vessel plates:

Material selection: High-temperature vessel plates usually use heat-resistant alloy steel or high-temperature alloy steel. These steels have good high-temperature strength, oxidation resistance and corrosion resistance, and can maintain structural stability and integrity in high-temperature environments.

Material specifications: The specifications of high-temperature vessel plates are determined according to specific design requirements and application scenarios. Common specifications include board thickness, width and length. Depending on the size and requirements of the container, custom plate sizes can be selected or appropriate plates selected from existing specifications.

Heat treatment: High temperature container plates usually require heat treatment to improve their high temperature strength and heat resistance. Common heat treatment methods include normalizing, tempering and quenching. These heat treatment processes can change the structural structure of steel and improve its high temperature resistance.

Forming and processing: High-temperature container plates can be formed and processed through processes such as hot rolling, cold rolling and hot processing. These processes can process steel plates into desired shapes and sizes, such as cylindrical, spherical, rectangular, etc.

Inspection and Certification: When manufacturing high-temperature vessel plates, strict quality inspection and certification are required to ensure that they comply with relevant standards and specifications. Common inspections include chemical composition analysis, mechanical property testing, metallographic inspection, ultrasonic testing, etc. In terms of certification, common certification agencies include ASME (American Society of Mechanical Engineers) certification, PED (Pressure Equipment Directive) certification, etc.

Quality Control: The manufacturing process of high-temperature container plates requires strict quality control to ensure product consistency and reliability. This includes controlling the quality of raw materials, strictly following process procedures, conducting on-site inspections and tests, recording key data, etc.
