  one、Common type

  1.RcThread(Equivalent toPTThread,Domestic is calledZG):Sealed cone internal thread,Dental corner55Spend;Taper is1:16。

  2.RThread:Sealed cone outer thread,Teeth55Spend,Taper1:16。

  3、PT Thread is 55 Sealed cone pipe thread,Available in Wyeth Threaded Family Cement 1:16.

  4.NPTThread:American standard60Rotal spinal tube thread,Taper1:16。

  5.GThread:Non-sealing cylindrical tube thread,Tooth angle55°。

  6、MThread:Meter thread,That is, metric threads。Teeth60Spend.

  Non-sealed tube thread without taper,Cylindrical tube thread,This thread is not allowed to get a sealed,Only add sealing material in the thread(Water tape、Raw material belt、Hemp rope, etc.),Can play the sealing effect。

  Sealed tube thread(Also called self-sealing tube thread)All use1:16Threaded teeth on the taper,Thereby achieving self-sealing,No need to encryption(But some tarable tube threads,Due to the problem,In actual operation,Still on the conical screw on some sealing material,Insurance。)。
