Product Description

Zhejiang ChengyuanUNS S32750 DIN/EN 1.4410 F53 SAF 2507Introduction

The plate flange connection is a method used to connect two pipes, pipe fittings, or equipment by placing flange pads between two flange plates and fastening them together with bolts. This type of connection is widely used in industrial pipelines as it is easy to use and can withstand high pressure. While flange connections may not be common in household pipes due to their small size and low pressure, they are prevalent in boiler rooms and production sites.

Flat flanges can be classified into carbon steel, stainless steel, and alloy steel depending on the material used. The structure of a flange can either be integral or unit. This type of connection is commonly found in chemical industry, electric power, petroleum pipelines, high-rise construction, coal mining, coking, and water pipelines. The production process for flanges typically involves forging, casting, or cutting (in the case of stainless steel 304 plate flanges).

F53 Duplex steel flanges are made of a ferritic-austenitic (duplex) stainless steel that offers a combination of beneficial properties from both ferritic and austenitic steels. With high levels of chromium and molybdenum, this steel exhibits excellent resistance to pitting corrosion, crevice corrosion, and uniform corrosion. Its two-phase microstructure ensures that it has a high resistance to stress corrosion cracking, along with strong mechanical strength.

These flanges are widely used in various industries, including the oil and natural gas industry for offshore rock-breaking oil platforms, petrochemical equipment, desalination equipment, and machinery and structural parts requiring high strength and corrosion resistance. Additionally, they are utilized in high-pressure and seawater pipes, heat exchanger tubes, water treatment and supply systems, fire-fighting and water spray systems, and combustion (waste) gas purification equipment.

The main components of F53 Duplex steel flanges are 25Cr-7Ni-4Mo-0.27N. If you want to learn more about these flanges, our website provides the latest news and updates about them, so be sure to visit regularly.
