Faumea Saina mo Saina Falegaosi Su'ega O'o'o Vaega Alloy Uamea paipa paipa ASTM A335 Heat-tetee Kesi Ea Boiler Suauu Ta'e.
Vaaiga lautele
Matou te faʻalagolago i le malosi faʻapitoa faʻapitoa ma faʻaauau pea ona fausia ni tekinolosi faʻapitoa e faʻafetaui ai le manaʻoga a China Manufacturer mo ASTM A335 Heat-Resisting Seamless Alloy Steel Pipe, Matou te tuʻuina atu le faʻamuamua i le maualuga ma le fiafia o tagata faʻatau ma mo lenei mea matou te mulimulitaʻia faiga faʻatonutonu lelei lelei. O lo'o iai nei a matou fale su'esu'e i totonu o fale e fa'ata'ita'i ai a matou fofo i itu ta'itasi i la'asaga eseese o gaioiga. O le umiaina o tekinolosi aupito lata mai, matou te faafaigofieina a matou tagata faʻatau i le faʻaogaina o mea faʻapitoa. Igoa o le Kamupani, e masani lava ona faʻatatau i le lelei o le faʻavae o le kamupani, saili mo le atinaʻe e ala i le maualuga o le faʻamaoni, faʻatumauina le tulaga maualuga o le pulega o le ISO, faʻatupuina tulaga maualuga kamupani e ala i agaga o le alualu i luma-faailoga le faamaoni ma le faamoemoe.
O loʻo i ai le faʻafeiloaʻiga o le T91/P91 faʻapipiʻi uamea paipa paipa
1. Fa'atomuaga Vasega Uamea
T91 / P91 o se uʻamea vevela ferritic, e le oak tuasivi falesuesue a le atunuu i le 1970 s amata suʻesuʻe ma atinae, ma i le 1983 i le ASME, lo tatou atunuu i le 1995 i le uamea i le tulaga GB 5310, faailoga e pei o le 10 cr9mo1vnbT91. / P91 sila sa 9 cr1mo (T9), i luga o le faavae o le sila, le mama, lelei tekinolosi metallurgy crystallization, faapea foi ma le micro alloying ma pulea taavale taavale ma pulea cooling tekinolosi, atiina ae se tupulaga fou o le vevela tetee uʻamea uʻamea. O le uʻamea o loʻo i ai mea lelei faʻainisinia lelei, maualuga le vevela o le matua pe a maeʻa le mautu, ma o le faʻaogaina o le faʻaogaina ma le faʻagasologa o gaioiga e lelei, talafeagai mo le maualuga o le vevela o le vaega o mea.
