Talu ai nei, o le tulaga faaleatunuu GB / T20878-2024 "Stainless Steel Grades and Chemical Compositions", faʻasaʻo e le Metallurgical Industry Information Standards Research Institute ma auai e Fujian Qingtuo Special Steel Technology Research Co., Ltd. ma isi iunite, na faʻasaʻolotoina ma o le a. e faatino ia Fepuari 1, 2025. . Ina ua mavae le toeitiiti atoa le ono tausaga o taumafaiga le faatuaoia, Qingtuo Vaega tutoatasi atiina ae le nitrogen-o loo i ai sili ona faamalosia austenitic stainless sila QN faasologa, e aofia ai le S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN18308), S35656 (QN18308) eseese. tulaga tetee a'a pei ole QF1804), S35706 (QN2008), S35886 (QN1906) ma le S35887 (QN2109) ua aofia ai i lenei tulaga, faʻatamaoaigaina le fausaga uʻamea uʻamea ma tuʻuina atu le malosi maualuga, mama, ma le maualuga o le faʻafefeteina mo le fanua o fausaga faʻapipiʻi uta. Le fuafuaga faʻataunuʻuina o ituaiga uʻamea uʻamea ma le maualuga o le saogalemu ma le tau-lelei.
S35656 (QN1804) faʻalagolago i le sili ona lelei o le faʻamaʻiina o le corrosion, weldability ma le maualalo o le vevela o mea faʻainisinia e aofia i le GB / T150.2-2024 "Pressure Vessels Part 2: Materials" ma le GB / T713.7-2023 "Steel Plate and Steel mo Meafaigaluega Faʻamalosi" Faʻatasi ai ma le Vaega 7: Uamea Faʻamaʻi ma le Uamea Faʻafefe" ma isi lua a le atunuʻu. tulaga fa'atatau i va'a mamafa. I nai tausaga ua tuanaʻi, QN faʻasologa uʻamea uʻamea ua fausia ai se filifili alamanuia mautu ma ua faʻaaogaina i vaega i le tele o uta-tauave fausaga maketi fanua e pei o le maualuga-saosaoa ala ala afi inisinia, fale prefabricated, subway inisinia, malosi, inisinia sami ma ipu mamafa.
Electropolishingose faiga fa'amae'a eletise e aveese ai se mea manifinifi o mea mai se vaega u'amea, e masani lava o u'amea u'amea po'o fa'amea tutusa. O le fa'agasologa e tu'u ai se i'ila, lamolemole, sili ona mama i luga.
Ua ta'ua foi ofa'alelei fa'aeletise, fa'apolopolo anodicpeeletise eletise, electropolishing e sili ona aoga mo le faʻamalo ma le deburring vaega e maʻaleʻale pe i ai geometries lavelave. O le fa'a'ele'ele'ele e fa'aleleia atili ai le mae'a o luga e ala i le fa'aitiitia o le talatala o luga e o'o atu i le 50%.
Electropolishing e mafai ona manatu e pei ofa'aliliu'ese eletise. Nai lo le fa'aopoopoina o se pa'u manifinifi o ion u'amea lelei, e fa'aogaina e le fa'aeletise le eletise eletise e fa'amavae ai se vaega manifinifi o ion uamea i se vaifofo eletise.
Electropolishing o u'amea uʻamea o le faʻaaogaina masani ole electropolishing. Electropolished u'amea u'amea o lo'o i ai se lamolemole, iila, ultra-mama fa'ai'uga e tetee a'a. E ui lava e toetoe lava o soʻo se uʻamea o le a aoga, o uʻamea sili ona faʻapipiʻiina o le 300- ma le 400-series stainless steel.
O le faʻamaeʻaina o le eletise e iai tulaga eseese mo le faʻaaogaina i faʻaoga eseese. O nei talosaga e mana'omia le vaeluaga o le fa'ai'uga. Electropolishing o se faagasologa e ala i le matua roughness o le Electropolished Stainless Steel Pipe ua faaitiitia. O le mea lea e sili atu ai le saʻo o paipa i fua ma e mafai ona faʻapipiʻi le EP Pipe ma le saʻo i faiga maʻaleʻale e pei o letalosaga tau alamanuia tau vailaau.
E iai a matou lava mea faʻapipiʻi ma gaosia faʻamalo eletise eletise e fetaui ma manaʻoga o matāʻupu eseese i lalo o le taʻitaʻiga a le au faʻapitoa a Korea.
O la matou EP Tube i ISO14644-1 Vasega 5 tulaga potu mama, faʻamamā taʻitasi mamama maualuga maualuga (UHP)nitrogen ona tapuni lea ma ato fa'alua. Fa'ailoga e agava'a ai tulaga o le gaosiga o paipa, vaila'au tu'ufa'atasiga, su'esu'eina o meafaitino, ma le maualuga o le talatala o luga e tu'uina atu mo mea uma.
