NPT是National (American) Pipe Thread的缩写,属于美国标准的60度锥管螺纹,用于北美地区.国家标准可查阅 GB/T12716。 PT是Pipe Thread的缩写,是55度密封圆锥管螺纹,属惠氏螺纹家族,多用于欧洲及英联邦国家.常用于水及煤气管行业,锥度规定为1:16.国家标准可查阅GB/T7306。

NPT——美国规格的锥度螺纹 PT ——日本的旧JIS规格锥度螺纹,相当于ISO规格的R,Rc DIN2999——欧洲主要是德国的管道用螺纹 NPT NPT就是一般用途的美国标准锥管螺纹。 其中N表示National (American)美国国家标准,P表示PIPE管子,T表示TAPER锥形,牙型角为60°。 这种管螺纹在北美地区常用,或在使用ANSI规范中经常看到。
它们两者的牙型角、斜度等指标都是相同的,关键是牙顶和牙底的削平高度不一样(螺纹牙高不一样。NPT可能有过盈也可能有间隙,但NPTF没有间隙;NPT内外螺纹均为圆锥,而NPTF外螺纹是圆锥,内螺纹则有圆锥、圆柱两种;NPT有右旋也有左旋,NPTF只有右旋一种旋向。) 3、 PT 是 Pipe Thread 的缩写,是 55 度密封圆锥管...
BSPP(British Standard Pipe Parallel (thread))为英制圆柱管螺纹代号,只有内螺纹,相当于国内的55度圆柱(平行)管螺纹,即G,而BSPT(British Standard Taper Pipe Thread)是一种英制圆锥管螺纹标准,指螺纹的牙型角为55度,螺纹具有1:16的锥度,相当于国内的55度圆锥管螺纹,即ZG,另外就是BSPF(British Standard Pipe ...

没错呢。答案NPT是美制锥管螺纹(National Pipe Thread)60°角PT与BSPT是一样的,英制锥管螺纹,55°的PT为旧英制螺纹,对应我国标准GB/T7306.2至于MPT,和FPT,生产厂家说的也不对,应该是Male (BS)PT和Female (BS)P,T分别对应国内的R和Rc,表示圆锥外螺纹和圆锥内螺纹 ...
