ASTM A105 Flange

Manufacturer & supplier of Class 300 Asme Sa105N Blind and Slip On Flange As Per ASME/ ANSI B16.5

carbon steel ASTM A105 Flange are made up of carbon steel or mild steel material. The material composition can have carbon, manganese, phosphorus, sulfur and iron in the composition. Viha Steel & Forging is a leading a105 carbon steel flanges manufacturers of these different carbon steel grades of flanges. Flanges are a type of connections for pipe lines to connect the pipes together. The specification for carbon steel material made flanges is the Asme Sa105N. There are different types of flanges based on the functionality such as the blind flange, slip on flange and orifice flange.

There are also different types based on the shapes. The carbon steel a105 blind flange is a very special type because it closes a connection and not expand it. The blind flanges can come in different varieties as well. The butterfly flange is an example. There are flat face, raised face and ring type joint flanges based on their face types. The cl.150 a105 lap joint flange ansi 16.5 is another type which has a lap joint on it for better connectivity. The flanges can range in size from ½ inches to 48 inches. The standards governing the dimensions can be ANSI, ASME, DIN, EN and other international standards.

The astm a105n weld neck flanges have a welded neck on them which allows better welding or fixture of the pipes into the flanges.  There are different pressure classes as well. The astm a105 slip on flange is used in most applications and it can come in different pressure classes ranging from 150 through 1500 and pressure numbers ranging from PN6 through PN64. Please feel free to contact us for more information on the different types such as the flange astm a105 asme b16.5 and others with pricing.
