Ellipsoidal Head

Ellipsoidal Head,also known as elliptical dished head,is the most widely used end closure for pressure vessels,storage tanks,reactors and heat exchangers.With a smooth elliptical curved surface,it features reasonable stress distribution,excellent pressure resistance and good sealing performance.Compared with torispherical heads and flat heads,ellipsoidal heads effectively disperse internal pressure load,reduce local stress concentration and extend the service life of pressure equipment.

We supply various ellipsoidal heads in multiple specifications.Available materials cover carbon steel Q245R,Q355R,SA516 Gr70,stainless steel 304,304L,316,316L and 2205 duplex stainless steel.Different material selections satisfy working conditions of high temperature,low temperature and corrosive media in different industries.

Our ellipsoidal heads are manufactured by integral cold stamping or hot spinning forming.After targeted heat treatment,internal residual stress is eliminated to achieve uniform wall thickness and stable mechanical properties.Multiple surface treatment options are available upon request,including shot blasting,anti-rust primer coating,pickling and passivation,polishing.Non-destructive testing such as ultrasonic testing can be arranged to detect hidden defects.

Custom production is supported strictly according to customer drawings,including customized diameter,wall thickness and transition edge size.Strict dimensional inspection is implemented during production to guarantee dimensional tolerance and welding quality.The transition edge of the ellipsoidal head can match cylindrical tank shells perfectly,bringing convenient on-site welding construction.

Ellipsoidal heads have broad application scenarios.They are commonly adopted in petrochemical industry,new energy,water treatment,food manufacturing,pharmaceutical engineering,thermal power and environmental protection equipment.Thanks to balanced performance and cost advantages,ellipsoidal heads become the preferred choice for most pressure vessel projects.

We keep stable supply capacity for bulk orders and sample orders.All products are properly packaged to prevent scratches,deformation and rust during long-distance sea transportation.We provide professional technical consultation and customized solutions for global equipment manufacturers,engineering contractors and trading companies.
