Industrial Pressure Vessel Suppliers

Industrial pressure vessels are key equipment in the industrial system, playing an irreplaceable role in the petrochemical, energy and power, pharmaceutical, and food sectors. These specialized devices withstand internal or external pressure to enable processes such as material storage, reaction, separation, and heat transfer.

Jiangsu Haijian Co., Ltd. provides specialized equipment for cement production, industrial solid waste incineration, and mining and metallurgical applications. Industrial pressure vessels can be categorized by process function into reaction vessels (such as polymerization reactors), heat exchange vessels (such as shell-and-tube heat exchangers), separation vessels (such as vapor-liquid separators), and storage vessels (such as spherical tanks). In terms of structural design, cylindrical and spherical geometries with excellent pressure-bearing properties are commonly used, and advanced design methods such as finite element analysis are used for stress optimization. In terms of material selection, in addition to traditional carbon steel and low-alloy steel, specialty materials such as duplex stainless steel and nickel-based alloys are increasingly being used to meet the demands of specialized operating conditions such as high temperature, high pressure, and severe corrosion.

Industrial pressure vessels require a systematic management system for maintenance:
1. Daily Maintenance:
Regularly check the integrity of safety accessories (safety valves, pressure gauges, etc.)
Monitor equipment operating parameters (pressure, temperature, etc.) for normal operation
Maintain the cleanliness of equipment surfaces and the integrity of the anti-corrosion coating
2. Periodic Inspections:
Perform annual and comprehensive inspections in accordance with standards
Focus on inspecting stress concentration areas such as welds and openings
Evaluate equipment condition using non-destructive testing methods such as ultrasound and radiography
3. Maintenance Management:
Establish comprehensive maintenance records
Major repairs must be performed by qualified personnel
Pressure and airtightness tests must be performed after maintenance
4. Technical Improvement:
Timely update of outdated equipment
Apply new monitoring technologies (such as acoustic emission monitoring)
Optimize operating process parameters
