Product Description

1192MM DIA 8MM THICK STAINLESS STEEL SPHERICAL CAP HEAD (316L)

Compared with elliptical dished heads, spherical dished heads offer superior pressure-bearing performance but involve higher manufacturing difficulty. As a result, elliptical structures are more commonly used in medium and low-pressure vessels. When the design pressure exceeds 10MPa, the use of spherical dished heads can reduce wall thickness, significantly lowering material costs. In storage-type vessels, their geometric characteristics can increase the effective volume by more than 15%.

Product Specifications

Item	Key Data
Diameter	1192mm
Wall Thickness	8mm

Production & Processing Details

Item	Key Data
Forming Methods	Hot Forming: Applicable to thick-walled materials/high-strength alloys; stress relief annealing required after forming Cold Forming: Suitable for 8mm-thick 316L stainless steel; no thermal deformation, ensuring structural precision
Surface Treatment	Sand Blasting: Ra 1.6μm - 3.2μm (enhances coating adhesion) Pickling: Forms a passive film (improves corrosion resistance, meets hygiene standards) Oil Coating: Food-grade anti-rust oil optional Descaling: Mechanical/chemical descaling (ensures a clean surface before welding) Customisation: E.g., mirror polishing for highly clean fields
Inspection Standards	Ultrasonic Testing (UT): 100% coverage of key parts to detect internal cracks and inclusions Penetrant Testing (PT): For non-ferrous materials, ensuring no surface leakage Radiographic Testing (RT): Complies with ASME BPVC Sec.V Level II standards Time of Flight Diffraction (TOFD): Accuracy ±0.1mm, precisely detects internal defects

Standards & Certifications

Item	Key Data
Applicable Standards	National Standards: GB/T 25198-2023 (China) Regional Standards: Adaptable to JIS B8243, EN 13445 International Standards: ASME BPVC Sec.VIII Div.1/2 (North America & global), PED 2014/68/EU (CE certification for European markets)
Certifications	ISO 9001:2015 Quality Management System Certification ASME "U" Stamp PED Module H Certification

Application Scenarios

Application Industry	Applicable Equipment/Scenarios
Chemical Industry	Small and medium-sized reactors, corrosive medium storage tanks (316L material resists acid and alkali erosion)
New Energy Field	Hydrogen storage tanks, lithium battery material mixing equipment (lightweight design + corrosion resistance)
Water Treatment Industry	Pressure chamber heads for reverse osmosis equipment (resists chloride ion corrosion, suitable for complex medium environments)

Packaging & Services

Item	Key Data
Packaging Solutions	Wooden Cases: For precision heads, waterproof and shockproof, export-grade fumigation Wooden Pallets: For bulk orders, stackable, load capacity ≥1000kg Steel Pallets: For heavy heads (≥500kg), reusable, corrosion-resistant Customised Packaging: E.g., vacuum packaging for stainless steel heads, seaworthy packaging for export shipping
Customisation & After-Sales Services	Customisation Services: Adjust size, material, forming process, etc., according to drawings Sample Service: Small-batch sample testing (5-10 units) Delivery Cycle: 20 days for standard heads, 30 days for customised heads
