Titanium flanges are important industrial connectors widely used in various fields such as chemical, petrochemical, shipping, marine engineering, nuclear industry, and aerospace.
The standard specifications for titanium flanges are quite extensive, with common standards including American, German, Japanese, British, and Chinese national standards, among others.
Common American standards include ANSI B16.5, MSS-SP-43, and API-6A. German standards include DIN 2527, DIN 2632-2638. Japanese standards include JIS B2220, British standards include BS4504, and Chinese standards include GB/T 9119-2010 and GH/T 20592-2007.
The main features of these standard specifications are as follows:
ANSI B16.5
ANSI B16.5 is a flange standard published by the American National Standards Institute (ANSI) for pipeline connections. This standard applies to titanium flanges with pressure ratings from Class 150 to 2500 and NPS 1/2 to 24, and also specifies requirements for flange dimensions, materials, sealing faces, and types of flanges.
MSS-SP-43
MSS-SP-43 is a standard published by the American Society of Mechanical Engineers (MSS) for high-strength, thin-type titanium flange connections. This standard specifies requirements for pipe diameter, thickness, flange dimensions, quality, and materials.
API-6A
API-6A is a standard published by the American Petroleum Institute (API) for titanium flange connections in the oil industry. This standard includes nominal sizes, blind flanges, flange plates, ring flanges, threaded flanges, and WECO threaded flanges, among other types.
DIN 2527
DIN 2527 is a titanium flange standard published by the German National Standardization Organization (DIN) for flange connections ranging from DN10 to DN4000. This standard is divided into different classes such as PN6, PN10, PN16, PN25, PN40, and more. Specifications for the dimensions, shape, sealing faces, and number, diameter, spacing, and depth of flange holes are provided.
DIN 2632-2638
DIN 2632-2638 is a series of titanium flange standards published by the German National Standardization Organization (DIN) for flange connections ranging from DN10 to DN4000. This standard consists of DIN 2631 and DIN 2633 to 2638, which specify parameters related to dimensions, shape, and sealing faces for different classes and types of titanium flanges.
JIS B2220
JIS B2220 is a titanium flange standard published by the Japanese Industrial Standards Committee (JIS) for flange connections with pressure ratings of 5K, 10K, 16K, 20K, 30K, and 40K, and pipe diameters ranging from DN10 to DN2000. This standard specifies requirements for the dimensions, shape, number, diameter, spacing, and depth of flange holes.
