Stainless steel flanges play an indispensable role in the industrial field as a key component in pipeline connection. In order to help customers better understand our products, SMLSCO will classify stainless steel flanges and introduce the characteristics of each product in detail.
Flange is a kind of parts connecting pipelines, pipe fittings, equipment and other components, consisting of two flanges, a gasket and a number of bolts. The flange usually has a through hole, used to connect the pipeline or equipment. The flange gasket is placed between the two flanges to prevent media leakage.
Classification and its characteristics:
1, flat welding flange:
With simple structure, suitable for pipeline connection under general pressure and temperature conditions, widely used in chemical industry, construction, water supply and other fields.
2、Butt welding flange:
With butt-welding flange, suitable for high temperature and high pressure working conditions, commonly used in oil, natural gas, chemical and other industries.
3、Blind flange: a kind of head flange
Good sealing: used for sealing the end of pipeline, with good sealing performance, preventing medium leakage.
Removable: easy for overhaul and maintenance, especially suitable for systems that need to be opened and closed frequently.
4, socket welding flange: a flange and pipe socket welding connection
Simple and reliable: easy welding, reliable connection, suitable for smaller diameter, lower pressure pipeline system.
Low cost: low manufacturing cost, is an economical and practical choice.
5、Loose set flange:
Wide applicability: loose set flanges are suitable for low and medium pressure piping systems, especially in the occasions where the pipelines need to be frequently replaced, maintained or overhauled. It can be easily disassembled and reconnected, and is suitable for pipeline connection in water treatment, heating and ventilation and some chemical processes.
6、Threaded flange:
Pressure resistance: in order to ensure the strength and pressure resistance of threads, the thickness of threaded flanges is usually thicker than that of general flanges, so that enough material can be reserved in the process of turning threads to ensure that the pressure resistance value of the flanges meets the usage requirements.
Easy installation: The biggest advantage of threaded flanges is that it is only necessary to thread and tighten the threaded pipe to it. This feature simplifies the installation process, especially suitable for occasions where welding is difficult or inconvenient.
The following are some of the common uses and applications of flanges：
Threaded flanges: Suitable for water, steam, air and other low-pressure piping connections, as well as instrumentation, valves and other pipe connections.
Welding flange: Suitable for high-pressure pipeline connection such as oil, natural gas, chemical industry and other high-pressure equipment connection such as boilers and pressure vessels.
Loose set flange: Suitable for fire fighting, medicine, food and other industries that require quick disassembly and installation of pipeline connections.
The following factors should be considered when choosing flanges：
Pressure: The pressure-bearing capacity of the flange should be greater than the pressure of the pipeline.
Temperature: the material of the flange should be able to withstand the operating temperature of the pipeline.
Medium: The material of the flange should be able to withstand the medium of the pipeline.
Connection mode: The connection mode of the flange should meet the design requirements of the pipeline.
Through the above categorization, we can clearly understand the characteristics and applicable scenarios of different types of flanges. When choosing the right flange, customers can flexibly match various types of flanges according to the specific project requirements and use environment to ensure the stable operation of the pipeline system. We are committed to providing diversified stainless steel flange products. SMLSCO is dedicated to meeting the diversified needs of customers for pipeline connections and providing reliable solutions for industrial applications.
