Ipuleti Lensimbi Engagqwali le-ASTM A240: Amabanga, Ukuqeda kanye Nokuhlola

Isingeniso

Ipuleti Lensimbi Engagqwali le-ASTM A240kuyinto engagqwali egoqwe ngokuyisicaba enikezwa ngaphansi kwencazelo elawula ukubizwa kwebanga, ukwakheka kwamakhemikhali kanye nezakhiwo zemishini zepuleti elimboziwe, ishidi kanye nomcu. Isetshenziselwa imikhumbi yokucindezela, amathangi, imishini yokucubungula, izingxenye zokwakha kanye nokwenziwa okuvamile. Abathengi kufanele bachaze ibanga eliqondile, ubukhulu, ukuqeda, izinga lokubekezelelana, uhlobo lwesitifiketi kanye nokuhlolwa okwengeziwe ngoba ukubizwa kwe-ASTM A240 kuphela akuchazi ngokuphelele umkhiqizo olethiwe.

Izinto Ezibalulekile Okufanele Uzicabangele:I-ASTM A240 ichaza izinga lezinto kanye nezidingo zokusebenza eziyinhloko. I-ASTM A480 ivame ukubhekiselwa ezidingweni zoku-oda ezijwayelekile, ukubekezelelana kobukhulu, ukuqedwa kwendawo kanye nezinhlinzeko zokuhlola. I-ASME SA240 iyincazelo yezinto ze-ASME ezihlobene esetshenziselwa ukwakhiwa kwekhodi lapho yamukelwa khona yikhodi yokuklama ebusayo. I-EN 10204 3.1 MTC kufanele ihlolwe ngokumakwa kwepuleti elibonakalayo, inombolo yokushisa, ubukhulu kanye ne-oda lokuthenga.

I-oda eliphelele ngobuchwepheshe kumele lihlukanise ipuleti eligoqekile elishisayo neshidi eligoqekile elibandayo, lichaze ukuthi yizilawuli zokujiya ezijwayelekile noma ezincane, libone ukuhlolwa okungafuneki okungonakalisi futhi licacise ukuthi ipuleti lizosetshenziswa yini ekucindezelweni, kwesakhiwo, kokugqwala noma kwesevisi yokushisa ephezulu.

Yini Embozwa Yi-ASTM A240?

I-ASTM A240/A240M ihlanganisa ipuleti lensimbi engagqwali le-chromium, i-chromium-nickel kanye ne-chromium-manganese-nickel, ishidi kanye nomcu ohloselwe imikhumbi yokucindezela kanye nokusetshenziswa okuvamile. Ububanzi buhlanganisa ukusetshenziswa kwezimboni, kwezakhiwo, kwezakhiwo kanye nobuhle. Indinganiso ibeka izidingo zamakhemikhali kanye nemikhawulo yempahla yemishini yamamaki abhalwe phansi.

I-ASTM A240 ayithathi indawo yazo zonke izidingo zokuthenga ezihlobene.
