Zithini izixhobo ze-NPT?

Izixhobo ze-NPT, okanye izixhobo zeNational Pipe Taper, luhlobo lokufakelwa ngemisonto olusetyenziswa kwiinkqubo zemibhobho kunye nemibhobho. Ezi zixhobo zinemisonto enciphileyo eyenza isivalo xa ziqinisiwe. Izixhobo ze-NPT zihlala zisetyenziswa kwiindawo apho ukuvuza kufuneka kuthintelwe, njengakwiinkqubo zamanzi, zomoya, okanye zegesi. Zifumaneka kwizinto ezahlukeneyo ezifana nobhedu, intsimbi engatyiwayo, kunye neplastiki, kwaye ziza ngobukhulu obahlukeneyo ukuze zilungele ububanzi obahlukeneyo bemibhobho kunye neepitshi zemisonto. Izixhobo ze-NPT zisetyenziswa kakhulu eMntla Melika nakwezinye iindawo, kodwa kubalulekile ukuqaphela ukuba azihambelani nemisonto efana naleyo ifumaneka kwizixhobo zeBritish Standard Pipe (BSP).

Ukongeza kwizixhobo zeNational Pipe Taper (NPT) ezisetyenziswa kakhulu eMntla Melika, kukho nezinye izixhobo zeNational Pipe Taper ezisetyenziswa kwimimandla eyahlukeneyo kwihlabathi liphela. Ezinye zezi ziquka:

I-BSPP (iBritish Standard Pipe Parallel): Ikwasetyenziswa e-UK nakwamanye amazwe anamathela kwimigangatho yaseBritane. Ngokungafaniyo ne-BSPT, izixhobo ze-BSPP zinemisonto ehambelanayo. Ngamanye amaxesha zibizwa ngokuba yimisonto ye-G.

I-BSPT (iBritish Standard Pipe Taper): Isetyenziswa kakhulu e-United Kingdom nakwamanye amazwe alandela imigangatho yaseBritane. Izixhobo ze-BSPT zine-engile ye-taper engama-55 degrees kwaye zihlala zibizwa ngokuba yi-R okanye i-Rp threads.

I-JIS (Imigangatho Yemizi-mveliso yaseJapan): Isetyenziswa eJapan nakwamanye amazwe aseAsia, izixhobo ze-JIS zine-engile ethe tyaba ye-30 degrees kwaye zifana ngendlela eziyilwe ngayo nezixhobo ze-BSPT.

I-ISO 7/1 (I-International Organisation for Standardization): Isetyenziswa kakhulu eYurophu nakwezinye iindawo ezilandela imigangatho ye-ISO. Ii-ISO 7/1 fittings zine-engile ethe tyaba ye-55 degrees kwaye zifana nee-BSPT fittings kodwa zinomahluko othile kubungakanani bemisonto.

Le yimizekelo embalwa nje yezixhobo zokufaka iipayipi ezisemgangathweni zesizwe, nganye ineenkcazo zayo kunye neendlela zokusebenzisa. Kubalulekile ukusebenzisa izixhobo ezifanelekileyo kwisicelo sakho esithile ukuqinisekisa ukuba ziyahambelana kwaye zisebenza kakuhle.
