 Ngamanye amaxesha, kodwa jonga ukutyhubela iingcongconi -xa unxiba kwaye unamathela kunye.

Kuthekani ukuba iyavuza?

 Jonga umonakalo okanye uzame itywina lomsesane  okanye i -o-ring ye  -o-teater yoKhuseleko olongezelelweyo.

Khumbula, ukufumana ilungelo elifanelekileyo kufana nokukhetha isixhobo esifanelekileyo somsebenzi. Imalunga neenkcukacha. Gcina ezi ngcebiso engqondweni, kwaye uya kuba sendleleni eya kwintambo yokuzifundisa i-proods  uqhagamshelo lwasimahla.

Ukuqukumbela

Xa sithetha ngentambo yentambo  njenge -NPSM , Xpf , Nptf , kunye ne -BSPT , sithetha ngamacandelo asinceda ukuba sijoyine imibhobho kunye nee-hoses kunye. Ezi zinto zilungele uqinisekisa ukuba amanzi ethu, igesi, kunye nezinye izinto zihamba ngemibhobho ngaphandle kokuvuza. Nantsi into esiyifundileyo:

I- lpt  luhlobo lwentambo enesitayile  esetyenziswa kakhulu e-USA. Yenza into eqinileyo kuba imisonto ingena encinci kwelinye icala, uhlobo olufana ne-cone.

I- lpf , ekwaziwa njenge -Elarseal Taper Teaper Teaper Toard I-National TAP , ifana ne-NPT kodwa yenzelwe ukwenza itywina elingenakukhalisela i-leak-free  ngaphandle kokufuna i -PTFE PAIP.

l i -NPSM , okanye umbhobho welizwe othe tye , unomtya othe tye othe tye . Kulungile ukwenza unxibelelwano  olunokuthatha inxaxheba kwaye lubuyise kunye ngokulula.

l bspt , ifutshane kwi -pipe esemgangathweni yaseBritani , iyafana ne-NPT kodwa ine- angle eyahlukileyo  kunye nesandi . Kuqhelekile kwiindawo ezisebenzisa imigangatho yaseBritane.

Khumbula, ukufumana ilungelo elifanelekileyo lithetha ukuba ukwazi imigangatho yakho ye-smreast  kunye nokukhetha uhlobo oluchanekileyo lweenkqubo zakho zoxinzelelo.

Imeko yexesha elizayo kwitekhnoloji efanelekileyo yokusebenza kunye neengcebiso zeshishini

Umhlaba wehlabathi filtings  uqhubeka ukutshintsha. Nantsi into eyenzekileyo:

I -Insocantity yokusebenza  kuya kuba ngcono. Sifumana iindlela zokwenza uqhagamshelo oluqinileyo ngaphandle kokufuna iirhasi  okanye ezi-o-rings.

l Izixhobo  ziyaphucuka, nazo. Oku kuthetha ukuba izinto ze-fittings zinokuphatha uxinzelelo olungaphezulu kwaye luphelele ixesha elide.

Iingcali ze -L iphakamisa ngokulandela iingcebiso ngezolimo , njengokusebenzisa i-ANSI / ASTE B1.20.1  ye-NPS okanye i-ISO 7  ye-ISPOP, ukuqinisekisa ukuba yonke into ilungile.
