DIN 2543 refers to a standard for titanium flanges under the German DIN (Deutsches Institut für Normung) system. Titanium flanges are designed for use in piping systems, connecting pipes, valves, pumps, and other equipment. They provide a secure method of joining pipes while allowing for easy disassembly when needed. These flanges are made from titanium or titanium alloys, which are known for their strength, corrosion resistance, and lightweight properties. Titanium is particularly advantageous in harsh environments such as marine, chemical processing, and high-temperature systems due to its resistance to oxidation and corrosion. Key Features: Material: Titanium or titanium alloys Corrosion Resistance: Excellent resistance to corrosion in various environments, particularly in acidic or saline conditions. Strength-to-weight ratio: Higher strength-to-weight ratio than steel. Temperature Tolerance: Titanium flanges can handle high temperatures and extreme conditions. Lightweight: Titanium is significantly lighter than steel, making transportation and handling easier. Pressure Rating (PN16):The "PN" (Pressure Nominal) value indicates the maximum pressure the flange can withstand at a specific temperature (typically 20°C).PN16 means the flange is rated for a maximum pressure of 16 bar (or 232 psi). Standard Flange Design: DIN 2543 titanium flanges follow a standardized design which includes: Type: Usually weld neck, slip-on, blind, or socket weld. Size: Flanges come in various sizes with different pressure ratings. Bolt Holes: They have drilled holes for bolts to connect to the mating flange.

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.
