- 商品名稱: Plate Flat Welding Flange
PL plate flat welding flange refers to a kind of flange that is connected with the container or pipeline by fillet weld. It is an arbitrary flange. Compared with the necked butt welding flange, the plate type flat welding flange has a simple structure and saves materials, but the rigidity and sealing performance are not as good as the necked butt welding flange. Plate type flat welding flanges are widely used in the connection of medium and low pressure vessels and 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.);
Common types and codes of flanges: 1, PL plate flat welding flange, 2, SO flat neck flange, 3, WN neck butt welding flange, 4, SW socket welding flange, 5, Th thread Flange, 6, BL flange cover, 7, eight-character blind plate, 8, PJ/SE neck butt welding ring loose flange, 9, PJ/PR flat welding ring loose flange, 10, reducing flange , 11, stainless steel flange, 12, pressure vessel flange, 13, American standard flat welding flange, 14, American standard SO flat neck flange, 15, American standard WN neck butt welding flange
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) .
National standards: GB/T9112-2010, GB/T9119-2010, GB/T9116-2010, GB/T9115-2010
Ministry of Chemical Industry Standards: HG/T20592-2009, HG/T20615-2009, HG5010-52～HG5028-58, HGJ44-91～HGJ65-91, HG20592-97
