Le mibhobho ine-NPS 2"ukuya ku-36".Nangona amabakala ahlukeneyo enovavanyo olwahlukileyo logwayimbo lobushushu umyinge wobushushu le mibhobho inokuma ukusuka kwi-45 degree C, ukuya kwi-195 degree C. Imibhobho ye-ASTM A333 kufuneka yenziwe ngenkqubo engenamthungo okanye yokuwelda apho kufuneka kungabikho sigcwalisi isinyithi ngexesha lenkqubo ye-welding.
Umgangatho we-ASTM A333 ugubungela udonga olungenamthungo kunye nekhabhoni edityanisiweyo kunye nombhobho wentsimbi wealloyi olungiselelwe ukusetyenziswa kumaqondo obushushu aphantsi.I-ASTM A333 i-alloy pipe iya kwenziwa yinkqubo engenamthungo okanye ye-welding kunye nokongezwa kwentsimbi yokuzalisa kwi-welding operation.Yonke imibhobho engenamthungo kunye newelding iya kunyangwa ukuze ilawule ubume bayo obuncinci.Uvavanyo lwe-tensile, iimvavanyo zempembelelo, iimvavanyo ze-hydrostatic, kunye novavanyo olungonakaliyo lombane luya kwenziwa ngokuhambelana neemfuno ezichaziweyo.Ezinye iisayizi zeemveliso zisenokungafumaneki phantsi kolu balulo ngenxa yokuba ubukhulu bodonga olunzima lunefuthe elibi kwiipropati zempembelelo zobushushu obuphantsi.
Ukuveliswa kombhobho wensimbi we-ASTM A333 kubandakanya uthotho lweziphene ezibonakalayo zomphezulu ukuze kuqinisekiswe ukuba zenziwe ngokufanelekileyo.Umbhobho wentsimbi we-ASTM A333 uya kuba phantsi kokwaliwa ukuba ukungafezeki komphezulu okwamkelekileyo akusasazwanga, kodwa kuvele kwindawo enkulu ngaphezu koko kuthathwa njengokugqitywa okufana nomsebenzi.Umbhobho ogqityiweyo uya kuba ngqo ngokufanelekileyo.
