I-ASTM A53 yi-intsimbi yekhabhoniezinokusetyenziswa njengentsimbi yokwakha okanye kwiipayipi ezinoxinzelelo oluphantsi.
Umbhobho wentsimbi yekhabhoni we-ASTM A53 (ASME SA53) yinkcazo egubungela umbhobho wentsimbi emnyama neshushu ediphiweyo enomthungo kwaye edibeneyo ukusuka kwi-NPS 1/8″ ukuya kwi-NPS 26. I-A 53 yenzelwe ukusetyenziswa koxinzelelo kunye noomatshini kwaye ikwafumaneka ukusetyenziswa ngokubanzi. Umphunga, amanzi, igesi kunye nemigca yomoya.
Ipayipi i-A53 ifumaneka kwiintlobo ezintathu (F, E, S) kunye neendidi ezimbini (A, B). Uhlobo lwe-A53 Uhlobo lwe-F lwenziwe ngokuwelda i-oven butt okanye ngokuwelda okuqhubekayo komthungo (Udidi A kuphela) Uhlobo lwe-A53 Uhlobo lwe-E ngokuwelda ukumelana (Iiklasi A kunye no-B).
Iklasi B A53iityhubhu ezingenamthungoyeyona mveliso yethu igqwesileyo phantsi kolu luhlu. Ityhubhu ye-A53 idla ngokuqinisekiswa kabini xa ithelekiswa netyhubhu engenamthungo ye-A106 B.
I-ASTM A53umbhobho wentsimbi ongenamthungoyiklasi esemgangathweni yaseMelika. I-A53-F ihambelana nezinto zaseTshayina i-Q235, i-A53-A ihambelana nezinto zaseTshayina iNombolo 10, kwaye i-A53-B ihambelana nezinto zaseTshayina iNombolo 20.
Inkqubo yokuvelisa Imibhobho yentsimbi engenamthungo yahlulwe yaba yimibhobho engenamthungo egoqwe ngobushushu kunye nemibhobho engenamthungo egoqwe ngobandayo ngokwenkqubo yokuvelisa.
1. Inkqubo yokuvelisa umbhobho wentsimbi engenamthungo eshukumayo eshushu: ityhubhu billet → ukufudumeza → ukugqobhoza → ukuqengqeleka okuthathu/ ukuqengqeleka okunqamlezileyo → ukususwa kombhobho → ubungakanani → ukupholisa → ukuqondisa → uvavanyo lwe-hydraulic → ukumakisha → ukufunyanwa kombhobho wentsimbi engenamthungo. Isiphumo. 2. Inkqubo yokuvelisa umbhobho wentsimbi engenamthungo eshukumayo ebandayo: ityhubhu billet → ukufudumeza → ukugqobhoza → ukugquma → ukuqhobosha → ukuqhobosha → ukutshiza ioyile → ukuzoba okubandayo okuninzi → ityhubhu billet → unyango lobushushu → ukuqondisa → uvavanyo lwe-hydraulic → ukumakisha → ithala leencwadi lokujova.
Isicelo1. Ulwakhiwo: imibhobho engaphantsi komhlaba, amanzi angaphantsi komhlaba, ukuthuthwa kwamanzi ashushu. 2. Umatshini, izihlahla zokuthwala, ukucutshungulwa kwezixhobo zoomatshini, njl. 3. Umbane: imibhobho yegesi, imibhobho yamanzi 4. Imibhobho engashukumiyo yamandla omoya, njl.
