Brand Overview

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.

Specifications
Head Type:
Torispherical Head
Inner Diameter:
1100mm - Suitable for medium-sized storage tanks, reactors, heat exchangers, and other general pressure-bearing equipment
Nominal Thickness:
4mm - Optimised design for working pressure range of 0.1MPa-40MPa, compatible with various media such as oil products, chemical media, and general fluids
Material:
316L Stainless Steel - Each batch is equipped with a complete Material Test Certificate (MTC)
Material Composition:
16%-18% chromium, 10%-14% nickel, and 2%-3% molybdenum, offering excellent corrosion resistance and medium erosion resistance
Surface Treatment:
External Surface Polished (Ra ≤ 0.8μm), smooth and clean, reducing medium adhesion and corrosion risks
Manufacturing & Processing Advantages

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.
