WUHAN LINMEI HEAD PLATE CO., LTD

On-site hot forming of large hemispherical heads. Glowing red steel plate blanks undergo integral hot-press forming. Compared to heads assembled from welded segments, integrally hot-formed hemispherical heads offer superior pressure-bearing capacity and a reduced risk of leakage. Our facility is equipped with a full suite of heavy-duty forming machinery, vertical lathes for precision machining, and flaw detection equipment; we undertake orders for large tank heads for the chemical and energy sectors, offering custom specifications and guaranteed delivery quality.

Looking forward to meeting you there!

Strict dimensional control, seamless curved surface, no stress concentration, reliable long-term sealing. Each unit goes through full material test & non-destructive testing before shipment. Custom service for all vessel head sizes, global industrial project partner.

Each conical section undergoes comprehensive X-ray inspection to detect micro-cracks from forming or laminar defects in the plate material, ensuring full compliance with pressure vessel industry standards; these sections can be paired with ellipsoidal heads, hemispherical heads, and cylindrical shells to provide fully customized pressure equipment assemblies.

We support bulk orders and offer rapid delivery; overseas importers are welcome to visit our facility.

We offer custom-manufactured elliptical, hemispherical, and conical heads tailored to the requirements of various industrial storage and pressure equipment applications. Supplied directly by the manufacturer, we provide reliable industrial equipment for your projects.

Linmei Factory covers all specs. Standard sizes in stock, custom non-standard sizes available. Hot pressing, precision machining, full quality inspection for pressure vessel use. All your required dimensions can be customized here, global export supported. DM for catalog & factory price.

Specially designed for clean environments in the food, pharmaceutical, water purification, and light industries, they feature a smooth, mirror-polished finish. Their seamless, easy-to-clean design eliminates impurity buildup and bacterial growth, fully complying with clean production standards.

High-temperature hot-press forming is performed using a 10,000-ton heavy-duty hydraulic press. Thick steel plates are fed into a constant-temperature furnace to undergo uniform softening and pressing; this process avoids the stress defects associated with cold spinning, enabling even thick-walled, high-strength steel to be formed into a standard spherical shape in a single operation, resulting in a smooth, depression-free surface.

All cylindrical shells strictly adhere to heavy-duty steel structure quality inspection standards; post-fabrication procedures include X-ray weld inspection and dimensional verification to ensure compliance with pressure and load-bearing requirements, making them suitable for diverse large-scale engineering applications such as industrial columns, pile casings, and storage tanks.

GLM Elliptical Head | Precision-Engineered Surfaces, Robust Manufacturing ▫️ One-piece hot-press forming ensures precise, uniform curvature ▫️ CNC spinning process maintains structural integrity for extra-large diameter heads ▫️ Precision-ground bevels ensure zero-error butt welding ▫️ 100% X-ray inspection guarantees a zero-defect product upon delivery

Standardized control is implemented across the entire workflow—from plate cutting and rolling to the storage of semi-finished products—effectively preventing shell deformation and dimensional deviations.

Our factory specializes in large-diameter thick-wall rolled cylinders for chemical storage tanks, reactors and energy pressure vessels. We supply customized size rolled shells for global petrochemical, metallurgy and new energy engineering projects. Reliable manufacturing strength, stable dimensional tolerance, long service life under high pressure. Welcome global contractors and distributors to send drawings for quotation.

Real photos of our giant horizontal pressure vessel semi-finished products in the workshop! From steel plate rolling and head welding to pipe prefabrication, every welding process is strictly controlled to ensure pressure safety.

Own equipment controls production precision throughout the entire process, eliminating outsourcing. Large-size elliptical heads made of carbon steel and alloy materials can be customized to your needs.

The entire process, from raw material cutting, CNC rolling, curvature correction to semi-finished product forming, is fully controllable, adapting to various heavy industry supporting needs such as pressure vessel cylinder sections, wind turbine towers, large pipelines, tank heads, and steel structure ring components.
