Product Specifications
- Inner Diameter: 700mm - Designed for small and medium-sized pressure vessels in chemical, pharmaceutical, and food processing industries
- Nominal Thickness: 3mm - Optimized for working pressure range of 0.1MPa-50MPa with weakly corrosive/non-corrosive media
- Material: S316 stainless steel with a complete Material Test Certificate (MTC) for each batch
- Material Composition: 16%-18% chromium, 10%-14% nickel, and 2%-3% molybdenum for superior corrosion resistance
Manufacturing Advantages
Produced using cold forming technology to retain the original ductility and weldability of S316 stainless steel. Our advanced hydraulic forming equipment ensures compliance with GB/T 25198 and ASME standards, producing smooth, uniform surfaces that prevent local stress concentration.
Quality Assurance
- Inspection Process: 100% full inspection, including penetrant testing (PT), ultrasonic testing (UT), and 3D laser scanning
- Compliance Standards: ASME BPVC Section VIII Division 1, GB/T 25198-2023, and PED 2014/68/EU directives
- Certifications: ISO 14001:2015, ISO 9001:2015, and ASME "U" Stamp approval
