Product Specification:
Our ASME hemispherical head is often made with carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. Hemispherical is the ideal shape for development of hemispherical dish end, because the pressure in the vessel is divided equally across the surface of the head. The radius (Ri) of the head equals the radius of the cylindrical part of the vessel.
Production Process of Heads:
Picking steel---Cutting---Welding---Heating---Spinning---Stamping---Trimming---Defect detection---QC---Warehousing---Transporttation
Shandong precision metal company can produce all types of dished ends heads. They can be manufactured from a number of steel types including pressure vessel and boiler quality, chrome moly and stainless steel. The company also offers 2:1 semi ellipsodial, hemispherical petals, torispherical ends as well as conical knuckled sections.
