I-ASTM A350 LF1, LF2 kunye ne-LF3 CARBON/ALLOY STEELS
IIMPAWU EZIJONGELEKILEYO
Ezi ntlobo zentsimbi zisetyenziswa njengeentsimbi zepayipi kwaye zikwasetyenziswa nakwimveliso yeeflange ezenziwe ngobumba. Zilungele ukusetyenziswa ukuya kuthi ga kwi -20ºF (LF1,) -50ºF (LF2) kunye -150ºF (LF3.)
Ukutyunjwa ngokweMigangatho

IZICELO
Ezi zintsimbi zisetyenziswa kakhulu kwiipayipi kunye iiflanges ezenziwe ngobuqili.
UKUQHUBA
Iigreyidi ze-LF1 kunye ne-LF2 zingcono ukuba zenziwe malunga ne-2250-2300ºF (1230-1260ºC) kwaye ayinakuba yenziwe ngaphantsi kwe-1650-1700ºF (900-925ºC.) I Uhlobo lwe-LF3 luya kwenziwa malunga ne-2150-2200ºF (1175-1205ºC) kwaye ayinakubayenziwe ngaphantsi kwe-1700ºF (925ºC.)
UNYANGO LWE-WELDING/UBUSHUSHU
Unyango lobushushu lweentsimbi zepayipi ngokuqinisekileyo luya kwenziwa rhoqo emva kokudityaniswa. Ulwakhiwo lwezi ntsimbi luya kuqala lumiselwe yinkqubo yokuqengqeleka/yokubumba. Umbhobho ngokwawo uya kubonelelwa ngeentsimbi eziqengqelekayo ezishushu, iiflanges njl.njl. ezivela kwiiforgings. Inkqubo yokwenyani yokudityaniswa iya kuba yeyona nto iphambili ekuqinisekiseni ukufaneleka kunye nokhuseleko lombhobho kunye nokusebenza kwawo okulandelayo. Unyango lobushushu kunye nonyango emva kobushushu lubalulekile.
Amanqanaba amathathu adweliswe apha adityaniswa lula ngazo zonke iindlela ezivavanyiweyo nezivavanyiweyo.
Ubuchule bokusebenza
Kwimeko yezinto ezifakelweyo kunye neeflanges, la manqanaba ikanikufuneka isetyenzwe ngomatshini njengoko kufuneka, kwaye amava aqhubekayo aya kugqiba ukuba umatshini wenziwe ngcono na kwisakhiwo esenziwe ngendlela efanayo, kwisakhiwo esiqhelekileyo okanye kwisakhiwo esifakwe i-anneal. Kuzo zombini iimeko, ngenxa yokubaluleka kokusetyenziswa kokugqibela, kufuneka kuthathwe iingcebiso kwinkampani yonyango lobushushu eyaziwayo..
