Cold Pressing 1300MM Ellipsoidal Head S30408 - Local Polishing with Bottom Opening
The ellipsoidal head (specification EHA 1300×8, material S30408) is manufactured by cold pressing and serves as a core-sealing, pressure-bearing component for general pressure-bearing equipment. Its standard ellipsoidal structure with a 2:1 major-to-minor axis ratio and straight edge optimises the medium flow path, reduces material stagnation, and adapts to multi-condition operating requirements from -20℃ to normal temperature. It can stably withstand medium and high working pressures, ensuring long-term safe operation of the equipment.
Produced by an enterprise with over 12 years of experience in precision head manufacturing, the product quality is recognised by relevant enterprises in multiple countries worldwide, suitable for core scenarios of pressure-bearing equipment in chemical, energy, food and pharmaceutical industries.
