ASTM A105 Carbon Steel Flanges SA105N Flange
We are manufacturers, suppliers and exporters of Carbon Steel A105 / A105N Flanges, which, the American Society for testing materials, classifies as a standard that covers forged Carbon-Steel piping parts that also include carbon steel pipe flanges, which are serviceable in pressure systems at room temperatures as well as temperatures higher than it. We produce Carbon Steel A105 / A105N Blind Flanges which are successful in pressure bearing and sealing pipe ends in heavy pressure applications like hydraulic systems since they have a maximum bending stress at the centre.
Carbon Steel A105 Plate Flanges, ASME SA105 Carbon Steel Slip On Flange manufacturer in China
ASTM A105 Flange is a specification of flanges. The specification can include different grades of stainless steel material made flanges. The flanges are of forged carbon steel and are meant for high temperature services. HT PIPE is a leading manufacturer and supplier of the ASTM A105 Flange types. Carbon Steel A105 Plate Flange has carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum and vanadium in its composition. Since the other materials are less than 1% of the composition, these are called the carbon steels. There are different types such as the SA105N Blind Flange which is used to close a pipe line. The ASME SA105 Carbon Steel Slip On Flanges also have good strength properties. The minimum yield strength of the A105 Flange ANSI B16.5 is 250MPa and the minimum tensile strength is 485MPa. The material is also hard with a Brinell hardness score of 187.
There are different pressure classes such as class 150, 300 and up to 2500 and PN6 through PN64. The A105 Class 300 Flange and below don’t need heat treatment while the higher pressure classes can undergo heat treatment. The flanges over 4 inches nominal bore size are applied with annealing, normalizing, normalized and quenched or normalized and tempered types of heat treatments. The ASTM A105 Pipe Flanges can be forged as well. A105 Class 300 Flange is good for welding applications. The boiler and pressure vessel guidelines as per ASME standards have to be followed while welding the material. There are also bolted as well as screwed flanges. When welding and bolting procedures are not appropriate, the ASTM A105 N Screwed Flange comes handy. The screwed flanges can be applied with threaded pipes to make a connection without the need for welding. Please contact us for the pricing and further information on the flanges.
