NPT stands rau National Pipe Tapered, uas yog US tus qauv rau tapered threads dav siv nyob rau hauv cov kav dej thiab fittings rau ntau tshaj 100 xyoo.
NPT kev sib txuas siv xov deformation, tsim cov hlau-rau-hlau foob qhov twg cov xov ntawm cov khoom sib txuas. Qhov kev tsim no yog qhov zoo raukev sib dhos ib leegtab sis yogtsis pom zood rau kev sib txuas uas yuav nquag sib sau ua ke thiab disassembled, raws li rov siv dua tuaj yeem ua rau hnav ntawm cov xov vim deformation.
Qhov zoo:
- Muaj txaus
- Nrov
- Kev sib dhos yooj yim yam tsis muaj flaring ntawm cov hlab, lub tes tsho, los yog cov ntsaws ruaj ruaj lossis o-rings NPTF thiab NPSM Xov Styles
Qhov tsis zoo:
- Tsis haum rau kev kub siab heev
- Yog tias rov ua dua, sealing kev ua haujlwm yuav txo qis
- Xov lubricant tuaj yeem ua rau cov kab mob sib kis
