ASME Cold Pressing 1100mm×4mm Torispherical Head with External Surface Polished (Ra ≤ 0.8μm)

As a benchmark manufacturer in China's precision pressure vessel component industry, Henan Guojiang has specialised in the R&D, production, and customisation of torispherical heads for over 12 years. Our products are exported to more than 10 countries worldwide, meeting the high-standard production requirements of the petrochemical, food processing, and general machinery industries, and providing reliable core component solutions for various pressure-bearing equipment.

Produced via ASME standard cold pressing forming technology to fully retain the original mechanical properties and welding compatibility of 316L stainless steel. Advanced hydraulic forming equipment ensures product dimensional accuracy and structural stability, strictly complying with ASME and national standards. No local stress concentration after forming, adapting to the working conditions of pressure-bearing equipment in multiple industries.

• Inspection Process: 100% full inspection, including ultrasonic testing (UT), penetrant testing (PT), and 3D laser scanning, eliminating micro-defects
• 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 certifications, and ASME "U" Stamp approval

Specifically designed for the corrosion resistance and adaptability requirements of general pressure-bearing equipment, applicable to:

• Head components of medium-sized storage tanks and reactors in the petrochemical industry
