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. 性能規(guī)范： □公稱壓力：1.0MPa～3.2MPa □適用溫度：-70℃～+450℃ □制造材料：20#,H62,1Cr18Ni9Ti,316L,0Cr18Ni12Mo2Ti □執(zhí)行標(biāo)準(zhǔn)：《儀表工手冊》樂嘉謙著 第五篇 儀表安裝>>第三章 儀表加工件>>第一節(jié) 儀表接頭

YZG12-4 壓力表接頭(B)此類接頭為兩端內(nèi)螺紋，一端內(nèi)螺紋是英制G1/4"和G1/2"兩種，接閥或其他設(shè)備。另一端內(nèi)螺紋為公制M20×1.5，有時(shí)也用英制G1/2"接壓力表。國產(chǎn)壓力表的螺紋都是公制的，Y-150以上都是M20×1.5。引進(jìn)系統(tǒng)要考慮國外習(xí)慣，壓力表都是英制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".
