Pressure Vessel

Product Overview

A pressure vessel is an enclosed apparatus designed to contain gases or liquids while withstanding specific pressure levels. Typically constructed from metal materials, these vessels boast high strength, rigidity, sealing capabilities, corrosion resistance, and the ability to endure high temperatures, ensuring safe and stable performance across various operational conditions.

Material and Structure

1.Materials: Pressure vessels are predominantly fabricated from metals such as carbon steel, stainless steel, or alloys. These materials offer excellent mechanical properties and chemical stability, catering to diverse environmental demands.
2.Structure: Featuring a modular design, pressure vessels are compact, facilitating easy installation and maintenance. Their internal structure is optimized to enhance load-bearing capacity and extend service life.

Characteristics and Classification

1.Characteristics: Pressure vessels are renowned for their high safety and reliability, capable of functioning in extreme environments characterized by high temperatures, pressures, and corrosive conditions. They exhibit excellent sealing and corrosion resistance.
2.Classification: Pressure vessels are categorized based on working pressure, medium hazard, and their role in production. They are typically classified into the first and second groups according to the medium, and further divided into Class I, Class II, and Class III based on pressure and volume.

Function and Application

1.Function: Pressure vessels find extensive use across various sectors, including industrial, civil, and military domains. They primarily serve purposes such as storage, transportation, heat transfer, mass transfer, and reaction processes, as well as the storage and transportation of pressurized or liquefied gases.
2.Application: Pressure vessels are crucial in industries like petrochemicals, chemical manufacturing, energy, pharmaceuticals, and environmental protection. In the petrochemical sector alone, they account for approximately 50% of all pressure vessels.

Manufacturing Process

The production of pressure vessels involves numerous stages, including raw material inspection, marking, cutting, rust removal, machining, rolling, assembly, welding, non-destructive testing, marking for openings, general inspection, heat treatment, pressure testing, and anti-corrosion measures. Each step adheres strictly to relevant standards and specifications to ensure product quality and safety.

Accessories and Attachments

Pressure vessels are equipped with various accessories and attachments, such as pressure gauges, thermometers, safety valves, level gauges, and other instruments and valves. Additionally, necessary insulation, heat insulation, and anti-corrosion equipment are included. Together, these components form a complete system, ensuring the vessel’s normal and efficient operation.
