DIN Standard Flanges are a type of flange that is manufactured to the DIN (Deutsches Institut Normung) standard. DIN flanges are available in a variety of styles, including slip-on, weld-neck, blind, threaded, and socket weld. They are made from a variety of materials, including carbon steel, alloy steel, and stainless steel. DIN flanges are used in a wide range of applications, including industrial piping systems, pressure vessels, and boilers. Technical Specifications A. Pressure rating: From PN6 to PN40. B. Temperature rating: From -20'C to +250'C. C. Material: Carbon Steel, Alloy Steel, and Stainless Steel. D. Finish: DIN flanges are available in a variety of finishes, including hot dip galvanized, painted, and stainless steel. Applications DIN Standard Flanges are used in a wide range of applications, including: 1. Industrial piping systems 2. Pressure vessels 3. Boilers 4. Tanks 5. Valves 6. Fittings Advantages Some of the advantages of DIN Standard Flanges include: I. They are manufactured to a high standard of quality. II. They are available in a variety of styles and materials. III. They are compatible with a variety of other piping components. IV. They are relatively easy to install and maintain.

A customized standard Gr1 titanium flange is a mechanical device used to connect pipes, valves, pumps, and other equipment to form a piping system. Flanges are available in different materials, and one of the most popular is titanium. Titanium flanges offer a range of benefits, including excellent corrosion resistance, high strength-to-weight ratio, and durability. They are typically circular in shape and are classified based on their size and pressure rating. The formation of the flange involves bolting two circles together, with the number of bolts and� bolt holes� varying according to the pressure classification. The� circular design� of the flange allows for efficient distribution of stress and pressure, making it a reliable and essential component in piping systems. Parameters Specifications:ASTM B381 / ASME SB381 Standard:ANSI, ASME, BS, DIN, EN, etc. Grades:Titanium Gr. 1, Titanium Gr. 2, Titanium Gr. 4, Titanium Gr. 5, Titanium Gr. 7 Class / Pressure:150#, 300#, 600#, 900#, 1500#, 2500#, etc. Features Corrosion Resistance: Titanium is highly resistant to corrosion, making it an ideal material for flanges used in corrosive environments. It resists corrosion caused by seawater, acids, alkalis, and other chemicals, making it an excellent choice for marine and chemical applications. High Strength-to-Weight Ratio: Titanium is a lightweight metal with a high strength-to-weight ratio. This feature makes it perfect for use in applications where weight is a concern, such as aerospace and military. Despite its lightness, titanium is incredibly strong and can withstand significant pressure and stress. Durability: Titanium has excellent durability, which means it can withstand� harsh conditions� and high temperatures without losing its strength or shape. This feature makes it ideal for use in applications such as power generation, chemical processing, and oil and gas industries. Non-Magnetic: Titanium is a non-magnetic material, which makes it ideal for use in applications where magnetic interference is a concern, such as electronic equipment and medical devices. Its non-magnetic property also makes it suitable for use in MRI machines and other medical imaging equipment. Applications Aerospace and Defense: used in aircraft and missile components, including engine components, landing gear, and fuel systems. Chemical Processing: used in chemical reactors, heat exchangers, and other equipment that comes into contact with corrosive chemicals. Oil and Gas: used in offshore drilling rigs, pipelines, and subsea equipment. Medical Devices: used in surgical instruments, implants, and medical imaging equipment. Power Generation: used in power generation equipment, including gas turbine components, heat exchangers, and condensers. They offer excellent resistance to corrosion caused by high temperatures and harsh environments.
