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
YZG12-2 压力表组合接头一端为外螺纹,螺纹为英制ZG1/8"和ZG1/4"两种,接别的仪表或阀门。另一端为内螺纹,接压力表。按压力表的螺纹,内螺纹有M10×1,M12×1.25,M14×1.5,M20×1.5和G1/2"五种。 One end of YZG12-2 pressure gauge combination connector is external thread,and the thread is British ZG1/8"and ZG1/4",which is connected to other instruments or valves.The other end is internal thread,connected to pressure gauge.According to the thread of pressure gauge,the internal thread has M10×1,M12×1.25,M14×1.5,M20×1.5 and G1/2".
