详细介绍:
三孔短管夹_D2型三孔短管夹_D2A型三孔短管夹,其设计标准中材料代号有两种:R和S。材料代号R表示20号钢,材料代号S表示Q235B。材料代号为R的三孔短管夹,适用于不高于450°C的环境温度之下;材料代号为S的三孔短管夹,适用于不高于300°C的环境温度之下。三孔短管夹由管夹、螺栓、螺母、套管组合而成,实际供货中,大部分客户不要求使用套管。订货时表示方法(举例)为:三孔短管夹_D2.133R(管道外径为133,20号钢材质)。标号举例:Dw=273,t=450°C,Pjg=1500kg力,标号为D2.273R;Dw=273,t=265°C,Pjg=4500kg力,标号为D2A.273S。选择D2型三孔短管夹,还是D2A型三孔短管夹,主要看需要承受的最大力是多少,即参考需要承受的Pmax值为多大(详见标准设计手册》。三孔短管夹是西北电力设计院《汽水管道支吊架设计手册1983年版》中最常见的管部吊架产品之一,广泛适用于汽水管道中的悬吊装置,不可或缺,一般与L7环形耳子、L1螺纹吊杆、T2双板整定弹簧组件,以及根部装置配合在一起使用,用F1/F2/F3/F4等连接件连接,形成基本管道悬吊装置。
There are two kinds of material for three-hole short clamp in the design handbook:R and S. Material code name R means 20# carbon steel,S means Q235B carbon three-hole clamp with code R is used the envirment under the temperature of 450゜C,that with S is used under 300゜C -hole clamp is componented of two pieces of clamps,bolts,nuts, supply, most customers do not require the use of casing. When ordering representation (for example): three hole short pipe _D2.133R (outside diameter of a pipe clamp for 133,20 steel material). Label, for example: Dw=273, t=450 DEG C, Pjg=1500kg, label for D2.273R; Dw=273, t=265 DEG C, Pjg=4500kg, label D2 type hole short pipe clamp, or d2a hole short pipe clamp, mainly to see the need to withstand the maximum force what is that reference to the need to withstand Pmax values for much (see standard design manual. Three hole short pipe clip is Northwest Electric Power Design Institute < steam water piping support and hanger design manual 1983 version > in the most common pipe hanger products0ne, widely used in steam water piping in the suspension device, indispensable, general and L7 annular Erzi, L1 thread threaded rod, T2 dual plate tuning spring assembly, and root device with together, F1/F2/F3/F4 connection connector, the basic pipeline suspension device is formed.
D2三孔短管夹的组合方式举例:G12单孔吊板+T2双板整定弹簧组件+F2六角扁螺母+L1螺纹吊杆+F2六角扁螺母+L8U形耳子+L4三孔吊板+2×D2三孔短管夹。
