The pressure vessel nozzle is a critical connecting component for petrochemical pressure vessels, designed to facilitate medium transmission between equipment. Engineered with a combination of
Ring Rolling processes, followed by precision
CNC Machining and rigorous non-destructive testing, it boasts exceptional mechanical strength and superior sealing performance—ensuring leak-proof operation even under harsh petrochemical working conditions.
Our pressure vessel nozzles are crafted from high-quality structural steels, adhering to strict manufacturing standards to meet the demanding requirements of petrochemical applications. With precise dimensional accuracy and reliable performance, they serve as the vital link in pressure vessel systems, guaranteeing safe and efficient medium transfer in oil refining, natural gas processing, and chemical reaction equipment.
We implement a stringent end-to-end manufacturing and quality inspection process to ensure the integrity, performance, and safety of every pressure vessel nozzle:
1.Incoming Material Inspection
2.Blank Cutting
3.Ring Rolling
6.Heat Treatment Inspection
7.Mechanical & Chemical Testing (Tensile, compression, bending tests; Impact test; End quenching test)
8.Precision CNC Machining (Rough Turning → Semi-Finish Turning → Finish Turning)
9.Comprehensive Inspection:
Dimensional & Geometric Tolerance Check
Non-Destructive Testing (Ultrasonic Testing, Phased Array Ultrasonic Testing, KARL DEUTSCH Immersion Ultrasonic Testing, MT Magnetic Particle Testing)
Traceability Marking
10.Anti-Corrosion Treatment (Zinc Spraying, Painting)
11.Cleaning | Packing | Storage
