Description
The profile may be elliptical, torispherical, hemispherical, spherical-cap, conical, or flat. steel dish heads are manufactured by hydraulic pressing, cold spinning, hot spinning, or a combined fabrication route. Forming is followed by trimming and flange correction so the end can be aligned with the vessel shell. Beveling, nozzle openings, reinforcement pieces, grinding, polishing, passivation, blasting, and coating preparation can be included. For large parts, lifting marks and transport supports are positioned around the final shape. Material identity and equipment tags stay with the product through inspection, storage, and dispatch.
Main Applications
Chemical reactors, heat exchangers, separators, and process-storage vessels.
Boilers, air receivers, heating tanks, and water-treatment equipment.
Energy, environmental, pharmaceutical, food, and machinery projects.
Fabrication packages requiring steel dish heads in several shapes or materials under one equipment schedule.
Product Advantages
The product form can follow the vessel calculation rather than a fixed catalog geometry.
Pressing and spinning provide different routes for repeat work and large custom sizes.
Weld edges, openings, and surface preparation can be completed before delivery.
Material identification and project marks help the fabricator match each piece to its drawing.
Our Services
Material and head form can be coordinated with the purchaser's vessel list. Regular sizes may be arranged on hydraulic press lines, while large or non-standard pieces can be reviewed for cold or hot spinning. We can prepare bevels, openings, direction marks, and reinforcement parts, then provide material certificates, inspection reports, and dimensional records. Export supports, shipping labels, and logistics coordination can follow the equipment number and site installation sequence.
Frequently Asked Questions (FAQ)
Q: Can different materials be supplied in the same project?
A: Yes. Each piece is identified separately so its material and document package remain traceable.
Q: Can surface treatment be included?
A: Yes. The process depends on steel grade, intended coating, and service condition.
Q: What details are required for steel dish heads?
A: Send the shape, material, diameter, thickness, flange height, openings, edge preparation, quantity, and inspection scope.
