SUS304 Torispherical Head With 511mm Diameter And 2.5mm Thickness

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: 700mm - Designed for small and medium-sized pressure vessels in chemical, pharmaceutical, and food processing industries
• Nominal Thickness: 3mm - Optimised 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

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.

• 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 S316 stainless steel torispherical head delivers stable performance and reliable quality, improving safety and efficiency for small and medium-sized pressure vessels.
