A105 carbon steel American standard flat welding flange with neck is made of American standard A105M carbon steel, which is a kind of flange that is very commonly used in American standard flanges. Also called SO in China, the full name of the flat-necked flange is a flat-welded steel pipe flange with a neck. The flat welding flange with neck is also a flat welding flange, because there is a short neck, which improves the strength of the flange and improves the bearing capacity of the flange, so it can be used for higher pressure pipelines. Flanges, also known as flanges, are parts that connect pipes to each other. There are holes on the flange, and the bolts connect the two flanges tightly. Flange connection refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a set of combined sealing structures. The flange used for piping refers to the inlet and outlet flanges of the equipment when used on equipment. The flanges are sealed with gaskets. Flanges are divided into threaded flanges and welded flanges.
Flanges can be divided into: carbon steel: (20#, A3, Q235, Q235A, Q235B, 20G, 16Mn, Q345, Q345R, ASTM A234WPB, ASTM A105, etc.); stainless steel: (304, 304L, 316, 316L) , S30408, S30403, S31608, S31603, SUS304, ASTM A403, TP321, TP317L, 347,0Cr18Ni9,00Cr19Ni10,00Cr17Ni14Mo2,1Cr18Ni9Ti, 06Cr17Ni12Mo2,022Cr17Ni12Mo2 etc.); steel: (16MnR, Cr5Mo, 12Cr1MoV, 10CrMo910,15CrMo, 12Cr2Mo1, A335P22, St45.8/Ⅲ, A10bB, etc.); Special alloy steel: (TP310S, 904L, Incoloy800, Incoloy825, Incoloy600, Incoloy625, etc.); Duplex stainless steel: (F51, S31803, S2205, F53, 2507, S32750, F55, 2607, S32760, etc.);

Commonly used sealing surface form codes for flanges: raised surface RF, concave surface FM, convex surface M, tenon surface T, groove surface G, full plane FF, ring connection surface RJ
Commonly used implementation standards for flanges: my country's current flange standards are divided into two systems, namely PN series (European system) and Class series (American system). The pressure marking specified in this standard is divided into PN marking and Class marking. PN marking has 12 pressure levels, namely: PN2.5; PN6; PN10; PN16; PN25; PN40; PN63; PN100; PN160; PN250; PN320; PN400. Class marked with 6 pressure levels, namely: Class 150; Class 300; Class 600; Class 900; Class1500; Class 2500. The executive standards include GB series (National Standard), JB series (Department of Machinery), HG series (Ministry of Chemical Industry), ASME B16.5 (American Standard), BS4504 (British Standard), DIN (German Standard), JIS (Japanese Standard) .
