Ukongeza, ukuxhathisa ukubola kwe-ASTM A335 P22 umbhobho wentsimbi ye-alloy nayo igqwesileyo, kwaye inokugcina ukusebenza kwayo kunye nobomi benkonzo ixesha elide kwiindawo ezinzima.
Okulandelayo, masifunde malunga nenkqubo yokwenziwa kweI-ASTM A335 P22umbhobho wentsimbi yengxubevange. Inkqubo yokuvelisa ikakhulu ibandakanya amakhonkco abalulekileyo afana nokunyibilikisa, ukuqengqeleka kunye nonyango lobushushu. Ngethuba lenkqubo yokunyibilika, izinto eziluhlaza zifudunyezwa kwisimo esityhidiweyo kwaye izinto ezifunekayo ze-alloy zongezwa ukuze zifumane ukubunjwa kweekhemikhali ezifunekayo kunye nesakhiwo se-alloy. Ngethuba lenkqubo yokuguqa, ukuchaneka komgangatho, umgangatho ophezulu kunye neempawu zomatshini wombhobho wensimbi ziqinisekiswa ngokulawula ngokuchanekileyo iiparitha ezifana nokushisa okuqengqelekayo, isantya kunye nokuguqulwa. Ekugqibeleni, ikhonkco lokunyanga ukushisa linceda ukuphelisa uxinzelelo oluseleyo ngaphakathi kombhobho wensimbi kunye nokuphucula ukuzinza kunye nokuqina.
Iimpawu zokusebenza zeI-ASTM A335 P22i-alloy steel pipe nayo enye yezizathu zokuthandwa kwayo. Okokuqala, umbhobho wensimbi unamandla amakhulu kunye nokuqina, unokumelana noxinzelelo oluphezulu kunye neempembelelo, kwaye uhlangabezane neemfuno zeemeko ezahlukeneyo zokusebenza ezinzima. Okwesibini, inokumelana ne-corrosion egqwesileyo kwaye inokumelana nokukhukuliseka kwezinto ezahlukeneyo zeekhemikhali ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide. Ukongeza, i-ASTM A335 P22 ingxubevange yentsimbi yombhobho nayo inokumelana nobushushu obuphezulu kwaye inokugcina iipropathi ezizinzileyo zoomatshini kunye neekhemikhali phantsi kokusingqongileyo kobushushu obuphezulu.
Kungenxa yezi mpawu zibalaseleyo zokusebenza ukuba i-ASTM A335 P22 ingxubevange yombhobho yentsimbi isetyenziswe ngokubanzi kwiinkalo ezininzi. Kwintsimi yepetroleum kunye neshishini lemichiza, umbhobho wensimbi usetyenziselwa ukuvelisa ukushisa okuphezulu kunye nemibhobho yoxinzelelo oluphezulu kunye nezixhobo zokuqinisekisa ukhuseleko kunye nokuzinza kwenkqubo yokuvelisa. Kwintsimi yamandla,I-ASTM A335 P22umbhobho wensimbi ye-alloy isetyenziswa ngokubanzi kwizixhobo eziphambili ezifana ne-boilers kunye ne-superheaters, ukumelana nobushushu obuphezulu kunye noxinzelelo oluphezulu lwe-steam kunye namanzi ashushu, ukubonelela ngesiqinisekiso esithembekileyo sokuvelisa amandla.
