Product name:Gr12 Titanium Hemispherical Head Standard: ASME VIII-I, DIN28013 Material: GR1, GR2, GR7, GR12 Size: Customized Gr12 Titanium Hemispherical Head Hemispherical head refers to the head composed of half spherical shell and straight edge (cylindrical short joint). The radius of curvature of the spherical shell is equal everywhere and the force is uniform. Compared with other heads, hemispherical heads require the smallest wall thickness under the same internal pressure. At the connection between the spherical shell and the cylinder with the same thickness, the edge stress caused by the change of curvature radius is only 3.1% of the overall membrane stress of the cylinder, which can be ignored. Therefore, the mechanical properties of hemispherical head are the best and the materials used are the most economical. Product name:Gr12 Titanium Hemispherical Head Standard: ASME VIII-I, DIN28013 Material: GR12 Size: Customized MOQ:1PC Spherical head, also known as spherical crown head, is a head formed by the spherical crown part of the spherical shell, including hemispherical head and non folded spherical head. The spherical head has excellent forging, smooth surface, acid and alkali resistance, high temperature resistance, beautiful appearance and strong texture performance. The applicable medium of spherical head is gas, liquid and steam. Spherical heads are used in petroleum, electronics, chemical industry, medicine, textile, food, machinery, construction, nuclear power, aerospace, military and other industries. Precautions for use of spherical head: 1. Carbon steel spherical head will crack in nitrate, ammonia, alkaline sodium and other environments. Explain to eliminate residual stress when ordering head. 2. Stress corrosion cracking of austenitic stainless steel will occur in the specific environment with chloride ions. Select appropriate materials when designing spherical head. 3. For carbon steel vessels requiring hot galvanizing or aluminizing, heat treatment shall be carried out first to remove residual stress Titanium grade 12 pipe (Ti-0.3Mo-0.8Ni) Chemical compositions(weight%,<=) Mo Ni Fe C N 0.2-0.4 0.6-0.9 0.30 0.08 0.03 H O Ti Others Total 0.015 0.25 Remainder 0.10 0.40 Physical properties(>=) Σb Tensile Strength (Mpa) σr0.2 Yield Strength (Mpa) δL0+50mm Elongation (%) ψ Reduction of area (%) 440 345 18

Product name:Gr7 Titanium dished Head Standard: ASME VIII-I, DIN28013 Material: GR1, GR2, GR7, GR12 Size: Customized Gr7 Titanium Hemispherical Head Dish-shaped head refers to the head composed of three parts: partial spherical shell, circular arc prayer side and good side (cylinder short treatment). Due to the abrupt change of radius of curvature at the junction between spherical shell and flanged edge, flanged edge and straight edge, the edge stress is much larger than the film stress caused by inner ash, and its mechanical properties are worse than that of spherical and elliptic head. Because of the shallow disc head, the requirements of stamping equipment and mold are low, so it is more convenient to manufacture. Rarely used in force vessels, only where pressure is low and a reduced head depth is required or where a die is lacking. The disc-shaped head is a continuous surface. The radius of curvature of the warp has a sudden change at the junction of three parts. As the curvature changes, there is bending stress. The result of the superposition of the bending stress and the tensile stress makes the stress in this part stand out from the other parts. Compared with the oval head, the stress distribution is not as uniform, but the machining is easier, so it is not ideal in engineering use. But when the mold processing of oval head is difficult, disc head is used instead. Size range: 50mm-10000mm with integral formed,larger sizes with subsection formed can be specified.
