Zigongono zazitsulo zosapanga dzimbiri zimapangidwa kuchokera ku magiredi achitsulo cha austenitic, makamaka mndandanda wa 300 (monga 304/304L ndi 316/316L), omwe amaphatikiza kuchuluka kwa chromium ndi faifi tambala kuti akhazikitse-zodzikonzera zokha. Njira yopangira nthawi zambiri imakhala ndi kuzizira kapena kukankhira kwa mandrel ndikutsatiridwa ndi njira yothetsera, chithandizo cha kutentha kwambiri chomwe chimasungunula ma carbides omwe amalowa mkati mwa kupanga ndikuchotsa kupsinjika kwamkati.
Magawo Ofunsira
M'magawo amankhwala ndi petrochemical, zoyikirazi zimagwiritsidwa ntchito kunyamula zinthu zankhanza, kuphatikiza ma acid ndi ma alkalis, pomwe chitsulo cha kaboni chingagonjetsedwe ndi okosijeni mwachangu. Makampani opanga zakudya, zakumwa, ndi mankhwala amadalira-malo opanda pobowo, aukhondo apamwamba-opanda chitsulo chosapanga dzimbiri m'chigongono kuti ateteze kuchulukirana kwa mabakiteriya ndi kupirira ma protocol a CIP (Clean{3}}in{4}}Place). Kuphatikiza apo, molybdenum-magiredi (monga 316) ndi zinthu zokhazikika pazainjiniya zam'madzi ndi mapulaneti a m'mphepete mwa nyanja chifukwa cha mphamvu yake yolimbana ndi chloride-kuchititsa kuti maenje atseke ndi dzimbiri m'madzi amchere.
Zikalata ndi Miyezo
Ma protocol athu opangira amatsatira mosamalitsa miyezo yapadziko lonse lapansi monga ASTM A403, ASME B16.9, ndi DIN. Timagwira ntchito pansi pa ISO9001 Quality Management System ndi ISO14001 Environmental Management System, ndipo tili ndi satifiketi ya EU Pressure Equipment Directive (PED) kuti tigwirizane ndi chitetezo. Zidziwitso izi zimatsimikizira kuti njira zathu zopangira zimakwaniritsa zowunikira komanso zofunikira zamakina zomwe zimafunikira pakumanga mafakitale apadziko lonse lapansi.
Fakitale Yathu
Ili ku Yanshan County Development Zone, malo athu opangira zinthu amakhala ndi mizere yopangira zitsulo zosapanga dzimbiri zosiyanitsidwa ndi madera azitsulo za kaboni kuti athetse chiwopsezo cha kuipitsidwa ndi chitsulo. Timapereka makonda amtundu uliwonse wa machubu osapanga dzimbiri amtundu uliwonse, kuphatikiza ma bend radii (afupi kapena atali), ma angles-osiyanasiyana, komanso makulidwe a makoma osiyanasiyana kuti agwirizane ndi zojambula zenizeni za isometric. Ntchito zathu zazikulu zimathandizidwa ndi njira zowongolera bwino, pogwiritsa ntchito ukadaulo wa Positive Material Identification (PMI) komanso kuyesa kwa hydrostatic kuti zitsimikizire kapangidwe kake ndi kukakamiza kwamafuta musanatumizidwe.
Mafunso Ofunsidwa Kawirikawiri (FAQ)
Q: Kodi pali kusiyana kotani pakati pa 304 ndi 316 kalasi elbows?
A: Kalasi 304 ndi muyezo aloyi kwa ambiri dzimbiri kukana. Gulu la 316 lili ndi kuwonjezera kwa 2-3% molybdenum, yomwe imathandizira kwambiri kukana kwa ma chloride ndikusungunula sulfuric acid, zomwe zimapangitsa kuti zikhale zofunikira m'malo am'madzi kapena ankhanza.
Q: Kodi mumapereka malipoti a Positive Material Identification (PMI)?
A: Inde. Kuti tiwonetsetse kuti pali mankhwala oyenera, timagwiritsa ntchito mfuti zoyesera za PMI pazinthu zomalizidwa. Timapereka malipotiwa limodzi ndi Mill Test Certificate (MTC) molingana ndi EN 10204 3.1.
Q: Kodi chithandizo cha kutentha chimagwiritsidwa ntchito pambuyo popanga?
A: Inde. Timapanga njira yothetsera kutentha kwa annealing pazitsulo zonse zosapanga dzimbiri pambuyo popanga. Izi zimabwezeretsa kukana kwa dzimbiri ndi zida zamakina zomwe zingasinthidwe panthawi yozizira kapena kugwada.
