Ipayipi lensimbi elingenamthungo le-ASTM A335
Incazelo emfushane:
I-ASTM A335 ivamise ukubizwa nge-chrome moly pipe ngenxa yekhemikhali equkethe i-Molybdenum (Mo) ne-Chromium (Cr).I-Molybdenum inyusa amandla ensimbi futhi i-Chromium (noma i-chrome) iyisakhi esibalulekile sensimbi engagqwali.Ipayipi lensimbi le-chrome moly alloy steel liyenza ilungele ukusetshenziswa ezimbonini zikagesi, izindawo zokuhluzwa, ezimbonini zamakhemikhali kaphethiloli, nasezinsizeni zenkundla kawoyela lapho uketshezi namagesi kuhanjiswa khona emazingeni okushisa aphakeme kakhulu nezingcindezi.
Sikulungele ukwabelana ngolwazi lwethu lokukhangisa emhlabeni wonke futhi sikuncoma ukuthi uthenge izimpahla ezifanele ngamanani okuthengisa anolaka.Ngakho-ke i-Profi Tools ikunikeza intengo engcono kakhulu yemali futhi sikulungele ukukhiqiza kanye ne-ASTM A335I-alloy Seamless Steel Pipe, Ikhwalithi iwukuphila kwefekthri, Ukugxila ekufuneni kwamakhasimende kuwumthombo wokusinda nentuthuko yenkampani, Sinamathela ekuthembekeni nasekusebenzeni okuhle ngokholo, sibheke phambili ekufikeni kwakho!

Ukumelana okuqinile nokuqhekeka emazingeni okushisa aphezulu kanye nezingcindezi eziphezulu.
Ingase isetshenziselwe IHydrogen Sulfide Corrosion Services.
Imelana nokuqhekeka kusuka ekuhlaselweni kwe-hydrogen kanye ne-embrittlement.
Imelana nokuqhekeka kokugqwala kwe-sulfide eshisayo.
Ingasetshenziselwa izinhlelo zokusebenza ze-NACE lapho izindawo ezimuncu zingaphansi kokushisa okuphezulu nokucindezela.
Ingasetshenziswa ku-NACE-MRO 175 Sour Service.
Ilungele izinhlelo zokusebenza zokuqhekeka kwe-creep.
Iyakwazi ukuphatha amazinga okushisa aphezulu ngokunwebeka okuphansi kakhulu.
Izinhlobo zensimbi ye-alloy embozwe ukucaciswa kwe-ASTM A335 - ASME SA335 zakhiwe ngesiqalo esithi "P", kusukela ku-P5 kuya ku-P92.Amabanga P11/P22 kanye ne-P91/92 ngokuvamile atholakala eziteshini zikagesi, kuyilapho ibanga elithi P5 ne-P9 livame ukusetshenziswa embonini ye-petrochemical.Amabanga P9, P91, ohlwini, abiza kakhulu
