What is a dish head (formed head)?

Dish heads (formed heads) are pressure-vessel or tank end closures such as hemispherical, ellipsoidal and conical heads, formed by cold spinning or hot forming depending on size, thickness and material.

Which materials and inspections are available?

Typical materials include carbon steel, alloy steel, stainless and duplex. Inspection and documents can include UT/PT/MT as required, marking/stamping per ITP, and MTC (EN 10204 3.1/3.2) by request.

What information should I include in an RFQ?

Please include ID/OD, head type (2:1 ellipsoidal, hemispherical, conical, etc.), thickness, material specification, design pressure/temperature, applicable code (e.g., ASME VIII), quantity and destination.

Technical Highlights

ASEA METAL supplies dish heads / formed heads in Korea for pressure vessels and storage tanks. Supported by cold spinning and hot forming routes, inspection options and export documentation. We fabricate dish heads and formed heads in Korea for pressure vessels and storage tanks. Typical plate materials can include ASTM A516 Grade 70 and stainless plate to project specification where required. Forming route (cold spinning / hot forming) is selected by thickness, diameter and code requirements. Inspection options and MTC documentation (EN 10204 3.1 / 3.2) support export deliveries. ASEA METAL is a Korean factory supplier that reviews drawings to confirm feasibility and lead time.

Contact / RFQ

How do you choose cold spinning vs. hot forming?

We select the forming route based on diameter, thickness and material grade to achieve the required geometry and mechanical properties per your vessel code and project specification.

Can you support project codes and traceability?

Yes. Production can be aligned with codes such as ASME VIII and project requirements, with marking, inspection records and MTC issued as agreed.

	Forming routes: Cold spinning and hot forming are selected by diameter, thickness, and material grade so that final head geometry and mechanical properties meet your pressure-vessel or storage-tank design.
	Standards & documentation: Production can be aligned with common vessel codes (e.g. ASME VIII) and project specs; material certificates (MTC), heat treatment records, and inspection reports are issued as agreed in your order.
	NDT & marking: UT, PT, MT, or other tests and stamping / marking can be applied per your ITP; final dimensions and profiles are checked against approved drawings before release.
	What to send for a quote: ID/OD, crown height or type (e.g. 2:1 elliptical, hemispherical), thickness, material spec, design pressure/temperature, and code - we respond with feasibility and lead time.
