SUS304 Ellipsoidal Head With 377mm Open Inner Diameter And 2mm Thickness

Henan Guojiang is a leading manufacturer in China's precision pressure vessel components sector, with over 12 years of experience in R&D, production and customisation of dished heads. Its products are exported to more than 10 countries and recognised by customers. In the field of general industrial equipment dished heads, it consistently adheres to high standards of reliability and precision to meet the strict adaptation requirements of various equipment for dished head components.

Open Inner Diameter: 377mm, customised for small storage tanks and atmospheric pressure vessels, matching the structure of storage and transportation equipment for media such as clean water and slightly corrosive industrial fluids.

Thickness: 2mm, designed based on atmospheric to low-pressure (0.1MPa-0.5MPa) equipment working conditions and medium flow characteristics, balancing structural strength and lightweight requirements.

Material: SUS304 stainless steel, containing 18% chromium and 8% nickel, with excellent rust resistance in normal temperatures and slightly corrosive environments, suitable for most non-extreme working condition equipment.

The cold pressing forming process is adopted as the core processing method for this ellipsoidal dished head. Cold pressing avoids the damage of high temperature to the metallographic structure of SUS304 stainless steel, ensuring the dished head maintains good structural stability and sealing adaptability during long-term use, and can be quickly installed without secondary processing.

Inspection Protocols: 100% full inspection, including Ultrasonic Testing (UT), Liquid Penetrant Testing (PT) and full-item inspection of appearance and dimensions, eliminating surface defects and dimensional deviations.

Applicable Standards: Compliant with GB/T 25198-2010, ASME BPVC Sec.VIII Div 1 and GB 150.4 pressure vessel standards, adapting to domestic industrial equipment specifications.

Certifications: Hold ISO 9001:2015 quality management system certification, ISO 14001:2015 environmental management system certification and ASME "U" Stamp approval, with quality meeting international standards.

As a general-purpose pressure vessel component, this SUS304 ellipsoidal dished head is mainly used in:

• Small industrial water storage tanks
• Atmospheric pressure chemical fluid transfer equipment
• Civil and commercial water purification equipment storage tanks

• Packaging: Individually wrapped with shock-absorbing bubble film, with reinforced cartons on the outer layer, suitable for domestic short-distance and long-distance transportation, avoiding collision damage during transportation.
• Customisation Services: Supports customisation of open inner diameter from 76mm to 10000mm and thickness from 2mm to 300mm. The shape of the dish head can be adjusted according to the equipment interface size to meet personalised adaptation needs.

• Excellent Rust Resistance: SUS304 material is suitable for most normal temperature media, reducing maintenance costs caused by equipment rust.
• Easy Installation: Precise size control and good structural adaptability allow direct connection with equipment flanges or interfaces, shortening the installation cycle.
• Controllable Cost: Lightweight thickness design reduces material consumption while ensuring durability, balancing equipment manufacturing costs and service life.
• Strong Versatility: Adapts to mainstream domestic small storage tanks and atmospheric pressure equipment models, and can be used without additional modification of the equipment structure.
