Explain: This series collects all kinds of connection forms and structural couplings,nipples,nozzles,rotary couplings, thermowells and other products in the automatic control instrument pipeline system.It is an essential connecting piece in the pipeline with a wide range of varieties, specifications and applications.Pressure gauge connector YZG12 series is a widely used connector.As long as there is a pressure gauge,there are YZG12 series connectors.The manufacturing material of YZG12 series joints shall be the same as or higher than the pipe material.The commonly used standard parts shall be made of 20# steel, 1Cr18Ni9Ti, 316 and 316L,and shall be selected at a higher level.The temperature can adapt to a wide range, usually T≤800°C, and it can be used normally. 性能规范: □公称压力:1.0MPa~3.2MPa □适用温度:-70℃~+450℃ □制造材料:20#,H62,1Cr18Ni9Ti,316L,0Cr18Ni12Mo2Ti □执行标准:《仪表工手册》乐嘉谦著 第五篇 仪表安装>>第三章 仪表加工件>>第一节 仪表接头

YZG12-4 压力表接头(B)此类接头为两端内螺纹,一端内螺纹是英制G1/4"和G1/2"两种,接阀或其他设备。另一端内螺纹为公制M20×1.5,有时也用英制G1/2"接压力表。国产压力表的螺纹都是公制的,Y-150以上都是M20×1.5。引进系统要考虑国外习惯,压力表都是英制G1/2"。 YZG12-4 pressure gauge connector (B) This type of connector is internal thread at both ends,and internal thread at one end is British G1/4"and G1/2",which is connected to valve or other equipment.The internal thread at the other end is metric M20×1.5.Sometimes British G1/2"is also used to connect the pressure gauge.The thread of domestic pressure gauge is metric,and the thread above Y-150 is M20×1.5.The imported system should take into account the foreign customs,and the pressure gauges are British G1/2".
