S30408 Stainless Steel Torispherical Dished Head Corrosion Resistant For Pressure Vessels

As a benchmark manufacturer in the domestic precision pressure vessel component field, Henan Guojiang has specialised in the R&D, production, and customisation of torispherical heads for over 12 years. Our products are recognised by customers in more than 10 countries worldwide, meeting strict requirements for high-standard industrial applications and providing reliable core component solutions.

• Inner Diameter: 1100mm - Designed for small and medium-sized pressure vessels in chemical, pharmaceutical, and food processing industries
• Nominal Thickness: 4mm - Optimised for working pressure range of 0.1MPa-50MPa with weakly corrosive/non-corrosive media
• Material: S30408 stainless steel with a complete Material Test Certificate (MTC) for each batch

Produced using cold forming technology to retain the original ductility and weldability of S30408 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.

• Inspection Process: 100% full inspection, including ultrasonic testing (UT), penetrant testing (PT), and 3D laser scanning
• Compliance Standards: GB/T 25198-2023, ASME BPVC Section VIII Division 1, and PED 2014/68/EU directives
• Certifications: ISO 9001:2015, ISO 14001:2015, and ASME "U" Stamp approval

Widely used in:

• Chemical industry: Corrosive liquid storage tanks, high-pressure reaction vessels
• Food and beverage industry: Dairy processing tanks, beverage storage equipment
• Pharmaceutical industry: Sanitary reactors, sterile liquid storage containers
• New energy and marine fields: Hydrogen storage tanks, battery material mixing tanks

• Reliable Structure: 700mm inner diameter and 3mm thickness ensure uniform stress distribution
• Hygienic & Corrosion-Resistant: Surface roughness Ra ≤ 0.8μm with excellent salt spray test results
• Cost Optimised: Precise thickness design balances performance and procurement costs

From raw material procurement to finished product delivery, Henan Guojiang maintains strict quality standards. Our 700×3 S30408 stainless steel torispherical head delivers stable performance and reliable quality, improving safety and efficiency for small and medium-sized pressure vessels.
