Chitoliro Chachitsulo chosapanga dzimbiri

Chitoliro chachitsulo chosapanga dzimbirindi chitsulo chosagwira ntchito-chopangidwa mozunguliramedia media, mulingo wa chloride, kutentha, kuthamanga, ndi njira yopangira(kuwotcherera, kupindika, pickling/passivation). Chitoliro cha "kumanja" sichimasankhidwa ndi dzina lokha-ogula nthawi zambiri amatsekamuyezo (ASTM/EN/ISO), mawonekedwe azinthu (zopanda msoko kapena zowotcherera), ndi kuyendera/zolembachoyamba, kenako tsimikizirani giredi ndi malo ofunikira kuti mukhale odalirika-kwanthawi yayitali.

Chitoliro chachitsulo chosapanga dzimbiri ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri ndi aloyi popanga madzi owononga, -kuthamanga kwambiri, komanso kutentha kwambiri. Mogwirizana ndi mfundo zodziwika padziko lonse za ASTM A312 / ASME SA312, mapaipi achitsulo osapanga dzimbiri amapangidwa mopanda msoko, zowotcherera, komanso zozizira kwambiri-njira zogwiritsiridwa ntchito kuti zikwaniritse zofunika m'mafakitale monga mafuta & gasi, petrochemical, kupanga magetsi, kuthira madzi, chakudya & chakumwa, ndi zomangamanga.

Monga azitsulo zosapanga dzimbiri chitoliro wopangandi kutumiza-ogwirizana nawozitsulo zosapanga dzimbiri chitoliro China, Octal Pipe imapereka mapaipi achitsulo osapanga dzimbiri okhala ndi kalasi yokwanira, kuwongolera koyenera, komanso kutsimikizika kolimba. Zogulitsa zathu zimatsimikiziridwa ndi miyezo yayikulu yapadziko lonse lapansi (ASTM, ASME, EN, DIN) ndipo zimakonzedwa kuti zikwaniritse zofuna zamakasitomala m'machitidwe ofunikira komanso magwiritsidwe antchito.

Octal Pipe imapereka mapaipi achitsulo osapanga dzimbiri opangidwa motsatira ASTM A312 / ASME SA312 ndi miyezo ina yapadziko lonse lapansi. Mapaipiwa amapezeka mumitundu yopanda msoko, yowotcherera (RW/EFW), komanso yozizira kwambiri (HCW), yomwe imapereka kukana kwa dzimbiri, kulimba kwa kutentha kwambiri, komanso kulondola kwenikweni.
Ndi magiredi ophimba TP304/304L, TP316/316L, TP321, TP347, TP310S, Duplex 2205, ndi Super Duplex 2507, mapaipi athu achitsulo chosapanga dzimbiri amagwira ntchito m'mafakitale osiyanasiyana kuphatikiza mafuta & gasi, petrochemical, kukonza mankhwala, kukonza mankhwala, kupanga madzi, kupanga magetsi & kupanga magetsi.
