Yintoni i-ISO 12151-4 kwaye yeyiphi inguqulelo yamva nje?
Isihloko se-ISO 12151-4 ludibaniso lwamandla e-hydraulic fluid kunye nokusetyenziswa ngokubanzi - ukufakwa kwe-hose fittings-icandelo le-4: Ukufakwa kwe-Hose kunye ne-ISO 6149 metric stud ends.
Ushicilelo lokuqala lukhutshwe kwi-2007 kwaye lulungiswe yiKomiti yezoBugcisa ISO/TC 131, iinkqubo zamandla e-Fluid, i-Subcommittee SC 4, izixhumi kunye neemveliso ezifanayo kunye namacandelo.
Inguqulelo esebenzayo yangoku yi-ISO 12151-4:2007, jonga ngezantsi kwephepha le-inshorensi ye-ISO 12151-4 esemgangathweni, kunye nekhonkco kwiwebhusayithi ye-ISO.

Ukuba ufuna izinto ngaphandle kwe-carbon steel, kulungile kwaye nceda ubuze inkonzo yethu yabathengi.
Ngaba ophumeleleyo unemveliso ehambelanayo ye-ISO 12151-4?
Ophumeleleyo umnxeba olu hlobo lokulinganisa umbhobho njenge-metric stud hose fitting, kunye nochungechunge lwenxalenye no.yi 102xx.
Ngezantsi ngumfanekiso oqhelekileyo wolu ngcelele.
102xx uthotho uhlobo oluqhelekileyo
Wi-metric stud hose yangaphakathi ifaka iinkcukacha jonga iphepha lekhathalogu.
[IkhonkcoukuKhuphela ikhathalogu]
WInxalenye yangaphakathi ye-metric stud fitting ye-hose assembly evavanyiweyo ngokuhambelana ne-ISO 19879, kunye nendibano epheleleyo yombhobho evavanyiweyo ngokwe-ISO 6605.
Imfuno yokugqiba kwi-ISO 12151-4 yi-72 h engathathi hlangothi yovavanyo lwesitshizi setyuwa ngokuhambelana ne-ISO 9227 kwaye akukho rusa ebomvu, iindawo eziphumeleleyo zigqithise kakhulu imfuneko ye-ISO 12151-4.
Bi-elow yi-ISO yokucaciswa kunye nomfanekiso wokuvavanya ityuwa yokutshiza.
