Standardization ensures safety and compatibility in the vast landscape of global industries. It facilitates international trade by providing a common ground for manufacturers, suppliers, and end-users. This article delves into the classifications of standard flanges in different countries, shedding light on their unique features and applications.

ANSI Flanges: The American Standard

ANSI flange In the United States, ANSI (American National Standards Institute) flanges are widely used. ANSI B16.5 and ANSI B16.47 are two common standards, each with its specifications. The former is suitable for nominal pipe sizes from 1/2" to 24", while the latter covers larger sizes.

DIN Flanges: German Precision

Din flange Germany follows the DIN (Deutsches Institut für Normung) standards for flanges. DIN and DIN are notable specifications, offering precision and reliability. DIN is designed for nominal pressure ratings, while DIN focuses on welding neck flanges.

JIS Flanges: Japanese Excellence

JIS flange Japan adheres to the JIS (Japanese Industrial Standards) for flanges. JIS B and JIS B provide detailed specifications for different types of flanges. B covers steel pipe flanges, while B focuses on hydraulic fluid power - flange connections.

BS Flanges: British Standards

BS flange British industries follow BS (British Standards) for flanges. BS 10 and BS are prominent standards, with BS 10 emphasizing on nominal sizes and BS providing specifications for circular flanges.

AS Flanges: Australian Standards

Australia adopts AS (Australian Standards) for flanges. AS and AS are commonly referenced standards, with AS covering table flanges and AS focusing on Class PN14 and PN16 flanges.

GOST Flanges: Russian Standards

Russian industries adhere to GOST (Gosudarstvennyy Standart) standards for flanges. GOST and GOST are noteworthy, with GOST concentrating on butt-welded flanges and GOST covering plate flanges.

Haihao Group(el,hu,it) are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

Chinese Flanges: GB/T Standards

China follows GB/T (Guobiao) standards for flanges. GB/T and GB/T are commonly used, with GB/T specifying welding neck flanges and GB/T covering plate flanges.

UNI Flanges: Italian Standards

Italy adopts UNI (Ente Nazionale Italiano di Unificazione) standards for flanges. UNI and UNI are notable, with UNI covering slip-on flanges and UNI providing specifications for welding neck flanges.

When comparing standard flanges from different countries, variations in materials, pressure and temperature ratings, and sizes become evident. It's crucial to understand these differences to ensure the proper selection of flanges for specific applications.

JIS B is a Japanese Industrial Standard that specifies the dimensions, materials, and technical requirements for steel pipe flanges in nominal sizes from 10A to A. JIS B flanges are commonly used in piping systems in Japan and other Asian countries.

There are several types of JIS B flanges, including slip-on, blind, socket weld, threaded, and welding neck flanges. Each type has its own unique features and applications.

JIS B flanges are typically made of carbon steel, stainless steel, or alloy steel, and are designed to withstand high temperatures and pressures. They are used in a variety of industries, including oil and gas, chemical processing, power generation, and water treatment.

When selecting JIS B flanges, it is important to consider factors such as the type of fluid or gas being transported, the temperature and pressure of the system, and the compatibility of the flange material with the piping material. It is also important to ensure that the flange meets the specific requirements of the application, including the size, shape, and pressure rating of the flange.
