ASTM A105/A105M is the material standard for carbon steel flanges.We usually called the flange size of 26 inches to 60 inches are large dimension flanges. ASME B16.47 is the production standard for large dimension flange.In this standard, there are two types of flanges:welding neck flanges (WN FLANGE) and blind flange (BL FLANGE). What is the advantages and application scope of large carbon steel flanges?
1.The characteristics of ASTM A105/A105M:
Ease of welding
High temperature stability
2.The standard of ASME B16.47 includes two types of flanges, series A and series B.
Size range: 26 inches to 60 inches.
Pressure: Series A : Class150, 300, 400, 600, 900 ; Series B:Class75, 150, 300, 400, 600, 900.
Flange types: Welding neck flange (WN FLANGE) ;Blind flange (BL FALNGE).
The difference between series A and series B flanges:
Series A specifies the flange size for ordinary flanges, while series B specifies the flange size for compact flanges.
The diameter of bolt holes on series A flanges is lager than that on series B flanges, and the number of bolt holes is less than that on series B flanges.
The bolt holes of the series B flange are smaller than those of the series A flange, and the number of bolt holes is more than that of the series A flange.
3.Advantages of ASTM A105/A105M Carbon Steel Forged Large Dimension Flange:
Improve space utilization
Reduce the overall weight of the pipeline
Enhance pipeline sealing
High strength and rigidity
Ease of installation.
Energy industry: Large dimension flanges are widely used in pipeline systems of various energy equipment, such as oil, natural gas, wind power, hydropower, etc. In the process of oil and gas exploration and extraction, large dimension flange connections are essential components because these pipeline systems need to withstand extreme conditions such as high pressure, high temperature, and corrosion. Large dimension flanges have excellent sealing performance and mechanical strength, which can ensure the safe operation of the pipeline system.
Construction industry: In construction engineering, large dimension flange connections are usually used for underground drainage systems, ventilation systems, air conditioning systems, and other large-scale projects such as buildings, factories, and bridges. These pipeline systems require frequent maintenance and replacement, and the reusability and easy disassembly performance of large flange connections provide convenience for maintenance and replacement.
Mechanical industry, chemical industry, wind power industry, sewage treatment industry: Large dimension flanges are also widely used in these fields.
