Standard: ASME VIII-I, DIN28013 Material: GR1, GR2, GR5, GR7, GR12 Size: Customized Gr2 Titanium Dish Head Product Information Titanium dish head is the end cap on the pressure vessel and is a main pressure-bearing part of the pressure vessel. The role played is the sealing effect. First, the upper and lower bottoms of the tank-shaped pressure vessel are made, and the second is that the pipe is at the end and is not going to extend forward. Then a titanium dish head is used to seal the pipe in the form of welding. There are blind plates and caps that are similar to the functions of titanium dish head, but those two products can be disassembled. After titanium dish head is welded, it cannot be disassembled. So the quality of titanium dish head is directly related to the long-term safe and reliable operation of the pressure vessel.

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.

Product name: 19mm Titanium pipe for heat exchanger Standard:ASTM B338 Material:Grade 1 Grade 2 titanium Diameter:19.1mm Wall thickness:1.0mm / 1.2mm Length:Max 16000mm Surface:Pickling surface/Polished Type:Seamless, welded Application:Heat Exchanger, chemical industry etc. Technique:Rolled 19mm Titanium pipe for heat exchanger Commonly used heat exchange tube size (outer diameter x wall thickness) is mainly φ 19mmx2mm, φ 25mmx2mm.5mm and φ 38mmX2mm.5mm seamless tube and φ 25mmx2mm and φ 38mmx2mm.5mm seamless tube. Standard tube length includes 1.5, 2.0, 3.0, 4.5, 6.0, 9.0m, etc. The use of small diameter can increase the heat transfer area per unit volume, compact structure, reduce metal consumption, improve the heat transfer coefficient. It is expected that the heat exchange tube of the same diameter heat exchanger is changed from φ 25mm to φ 19mm, the heat exchange area can be increased by about 40%, saving more than 20% of metal.
