Pressure Vessel Manufacturers

I. Core Classification and Principles of Pressure Vessels

1. Classification Standards (by Purpose)

2. Core Working Principles

• Pressure-bearing principle: Construct a closed cavity through high-strength materials and precision welding technology, which can bear a working pressure of 0.1MPa and above, and adapt to the physical characteristics of different media.
• Function realization principle: Reaction type promotes medium reaction through temperature and pressure control; heat exchange type completes heat transfer through heat conduction/convection; separation type realizes separation by using differences in medium density or state; storage type maintains medium purity and pressure stability through sealing structure.
• Kaidi's technical advantages: The core components are manufactured by CNC precision processing equipment, combined with independently developed pressure monitoring modules, ensuring that the pressure fluctuation of the equipment is ≤±0.02MPa under the working condition of -45℃ to 50℃, meeting food-grade and medical-grade use standards.

II. Product Comparison and Core Selling Points

1. Comparison between Kaidi Pressure Vessels and Conventional Industry Products

2. Core Selling Points

• Safety and Compliance: Strictly follow national special equipment standards, each equipment passes factory pressure test and third-party testing, eliminating risks such as overpressure explosion and medium leakage.
• Customized Adaptation: Relying on the technical strength of Kaidi's Shanghai Hongqiao R&D Center, it can customize exclusive equipment with a volume of 30L to 10000L and a pressure level of 0.1MPa-10MPa according to customer scenario needs.
• Long-term Stability: Adopting lean manufacturing technology, the service life of core components is 30% higher than the industry average, and 3-year trouble-free operation has been achieved in large-scale projects such as GLP, JD Cold Chain, and Shanghai Pharmaceuticals.
• Full-chain Service: Provide integrated services from pre-scheme design, mid-term installation and commissioning to later maintenance. Multiple branches across the country ensure timely service coverage.

III. Application Cases and Maintenance Guidelines

1. Typical Application Cases

• Food Cold Chain Scenario: Provided heat exchange type Pressure Vessels for a food processing enterprise in Shandong, adapting to the needs of -36℃ quick-freezing warehouses, realizing 6 tons/10 hours of pig ear quick-freezing processing, improving cooling efficiency by 25%, and ensuring the integrity of food cells.
• Medical Storage Scenario: Customized storage type Pressure Vessels for China National Pharmaceutical Group for low-temperature storage of pharmaceutical intermediates, meeting the 0.3MPa pressure stability requirement, and the medium purity retention rate reaching 99.8%.
• Refrigeration System Supporting: Provided separation type Pressure Vessels for SF Cold Chain cold storage projects, realizing efficient oil separation in refrigeration systems, improving equipment operation energy efficiency by 18%, and reducing cold chain operation costs.

2. Professional Maintenance Guidelines

• Daily Maintenance: Check whether the pressure gauge display is normal every day and whether there is leakage at the sealing part; clean the equipment surface and safety accessories every week to ensure the safety valve is unblocked.
• Regular Inspection: The first regular inspection of metal Pressure Vessels shall be completed within 3 years after commissioning, and the subsequent inspection interval shall not exceed 6 years; the first inspection of non-metallic Pressure Vessels shall not exceed 1 year, and the subsequent inspection interval shall not exceed 3 years.
• Maintenance Specifications: Before maintenance, the power source must be cut off, a "No Switching On" sign shall be hung, and the medium in the vessel shall be thoroughly cleaned and replaced; welding maintenance shall be operated by professional certified personnel to avoid welding defects.
• Kaidi Support: Provide free maintenance training and maintenance manual, and professional technicians can be appointed for on-site maintenance to ensure that the equipment always meets the safe operation standards.

IV. Frequently Asked Questions (FAQ)

• Q: What are the restrictions on the applicable media of Pressure Vessels?
• A: It can be adapted to refrigerants, food raw materials, pharmaceutical intermediates, conventional chemical media, etc. For special corrosive media, please inform in advance. Kaidi will customize production with corrosion-resistant materials to avoid equipment corrosion damage.
• Q: How to deal with abnormal pressure fluctuation of the equipment?
• A: First, stop the operation of the equipment and check whether the pressure gauge and safety accessories are normal; if self-inspection is not possible, you can call Kaidi's after-sales hotline, and technical personnel will provide remote guidance or on-site maintenance services within 24 hours.
• Q: Can Kaidi's Pressure Vessels be exported overseas?
• A: Yes, the products have passed relevant international safety certifications and have export qualifications. The overseas service network can provide installation, commissioning and after-sales support, and have been exported to many countries and regions.
