Thick Wall Pressure Head

Thick Wall Pressure Heads are heavy-duty dished closures specially designed for high-pressure,deep-well and harsh industrial working conditions.Different from standard thin-wall tank heads,these thick-wall heads feature increased wall thickness,higher mechanical strength and stronger deformation resistance,effectively bearing extreme internal pressure and alternating load.They are widely matched with high-pressure vessels,high-pressure reactors,hydraulic cylinders and special pressure-bearing equipment.

We manufacture thick wall pressure heads in multiple shapes,including ellipsoidal heads,hemispherical heads and torispherical heads.Available materials include carbon steel SA516 Gr70,Q355R,stainless steel 316L,2205 duplex stainless steel and alloy steel.Each material option meets strict requirements for high pressure,low temperature and medium corrosion in different industrial environments.

Our thick wall pressure heads are processed by hot spinning and integral hot forming.Professional heat treatment is carried out to remove internal stress,optimize metal grain structure and avoid fatigue cracking under long-term pressure impact.Strict thickness detection and dimensional inspection are implemented throughout production to ensure consistent wall thickness and precise machining tolerance.Surface treatments such as shot blasting,anti-rust painting and polishing can be provided as requested.

Comprehensive non-destructive testing including ultrasonic testing and magnetic particle inspection is available to detect internal defects.All production follows international pressure vessel specifications.Custom processing is supported according to customer drawings,covering customized outer diameter,wall thickness,straight edge length and chamfer size.The welding edge is finely processed to achieve high-quality assembly with cylinder shells.

Thick wall pressure heads are essential components for petrochemical high-pressure equipment,natural gas storage devices,new energy pressure equipment,metallurgical machinery and high-pressure pipeline systems.For projects requiring long service life and high safety redundancy,thick wall pressure heads are the reliable choice to prevent equipment leakage and structural failure.

We support small-batch sample production and large-volume bulk orders.Products adopt reinforced packaging to prevent collision and deformation during ocean transportation.We supply global equipment manufacturers and engineering contractors with reliable thick-wall pressure solutions and professional technical support.
