I-ASME luphawu lwentengiso olubhalisiweyo lwe-American Society of Mechanical Engineers.

Ububanzi

Lo mgangatho uquka ukumiselwa komgangatho wemibhobho yentsimbi edityanisiweyo kunye nengenamthungo yobushushu obuphezulu okanye obuphantsi kunye noxinzelelo.Eli gama lombhobho lisetyenziswa njengoko lahlulwe kwityhubhu ukuze lisetyenziswe kwiimveliso ze-tubular zobukhulu obuqhelekileyo obusetyenziselwa imibhobho kunye neenkqubo zokubhobhoza.

Ubungakanani

Ubungakanani beyonke ipayipiichongwa ngobungakanani bombhobho oqhelekileyo.

Ukwenziwa kombhobho we-NPS 1/8 (DN 6) ukuya kwi-NPS 12 (DN 300) equkayo isekelwe kwidayamitha yangaphandle esemgangathweni (OD).Le OD yakhethwa kuqala ukuze umbhobho one-OD esemgangathweni kunye nobukhulu bodonga obuqhelekileyo bexesha bekuya kuba nobukhulu obungaphakathi (ID) obulingana nobukhulu obuqhelekileyo.

Nangona kungekho lunxulumano lunjalo phakathi kobungqingqwa obukhoyo obukhoyo-OD kunye nobungakanani begama-obu bukhulu buqhelekileyo kunye nee-OD eziqhelekileyo ziyaqhubeka zisetyenziswa “njengesiqhelo”.

Imitshato

Imigangatho yedimensional yombhobho echazwe apha yeyemveliso egutyungelwe kwiinkcukacha ze-ASTM.
