Yanshan County Bo Yan Pipe Industry Co., through years of effort has now become a large-scale (low-alloy tube (16Mn Q345B, C, D, E, 27SiMn) high-pressure boiler tube (20G GB5310-1995) imported high-pressure pipe (ST45 .8-III SA-106B SA-210C DIN17175-79) domestic alloy tube (42CrMo, 12Cr1MoV, 15CrMo 10CrMo910 Cr5Mo T91 P91 Steel Institute 102 WB36) imported alloy tube (A335P12 STFA22 A335P22 STFA24 A335P11 A335P5 A335P91 (T91) STFA25 WB36 (15NiCuMoNB5 ) fertilizer tube GB6479-2000 GB9948-88 petroleum cracking tube oil casing J55 / K55 N80-1 N80 (Q) L80 C90 low-pressure boiler pipe GB3087-1999 transmission fluid GB8163-1999 ship dedicated pipe GB5312-99 stainless steel tube 304 304L 321 321L 347H 316L 317L steel plate (15CrMoR 12Cr1MoR 12Cr2Mo 14Cr1MoR 16MnR fittings elbow tee high alloy flange profile: high alloy flange that is attached to the pipe or tube, circle head end portion of the disc, the disc evenly distributed number of bolt holes, and is made of high alloy, when the pipe or vessel for removable attachment of the most commonly used high-pressure alloy flanges important parts Category: Many types of high alloy flange, use can be divided tube Flange (ie pipeline flange) and pressure vessel flange (Flanges); according to the shape can be divided into round, square, oval and special flange shapes; by pressure can be divided into medium and low voltage flange, and High Pressure Flange; its connection with the pipe or vessel can be divided into flat welding flange; sleeve welded flange, welded flange, loose flange, threaded flange and flange cover (blind) and other basic type High-pressure alloy flanges extended content: certain nominal vessel flange diameters suitable for a certain nominal diameter container 15crmo alloy fittings, the same 12cr1movg alloy fittings, certain nominal diameter of pipe flanges apply certain nominal diameter of the pipe, fittings, but since the container. The nominal diameter equal to the inner diameter of the alloy tube, pipe nominal diameter, in general, not equal to the diameter, not equal to the diameter, and its inner diameter was similar. So the same nominal diameter vessel flange and pipe flange The size is not the same as the two can not substitute each other with a pipe for the container Simplified 15crmog alloy tube, then use high-pressure alloy pipe flange flange applications: high alloy flanges are metallurgy, chemical, petrochemical, thermal, industrial furnaces, automatic control, water supply and drainage, heating, ventilation and other engineering design using very common, involves a wide range of parts, but also piping design, pipe fittings and valves in essential parts. High alloy flange suitable for valves, pumps, chemical machinery, petrochemical machinery, pipeline fittings and other equipment. p22 alloy tube _ Bo Yan Pipe (Online) _ alloy fittings provided by the Yanshan Xian Yan Bo Industry Co., Ltd.
