Chubu chamkuwa chimapangidwa ndi 99.9% mkuwa wangwiro ndi zinthu zazing'ono zomwe zimapangidwira ndipo zimakwaniritsa miyezo yofalitsidwa ya ASTM.Izo zimabwera mumitundu yolimba komanso yofewa, kutanthauza kuti chubu chatsekedwa kuti chichepetse. amagwiritsidwa ntchito mu mapaipi, HVAC, firiji, kupereka mpweya wamankhwala, makina oponderezedwa a mpweya ndi machitidwe a cryogenic.Kuphatikiza pa mapaipi amkuwa wamba, mapaipi apadera a alloy amapezekanso.
Mawu akuti mapaipi amkuwa amatsutsana pang'ono. Chinthu chikapangidwa kukhala koyilo, nthawi zina amatchedwa chubu chamkuwa chifukwa chimawonjezera kusinthasintha komanso kutha kupindika zinthuzo mosavuta. wogulitsa.
Machubu onse ndi ofanana kupatula kusiyana kwa makulidwe a khoma, ndi K-chubu yomwe ili ndi makoma okhuthala kwambiri ndipo chifukwa chake imakhala yothamanga kwambiri. Machubuwa amatchedwa 1/8" ang'onoang'ono kuposa awiri akunja ndipo amapezeka mumiyeso yowongoka ya chubu kuyambira 1/4 "mpaka 12", onse okoka (molimba) ndi annealed (ofewa). zojambulidwa ndi wopanga, zobiriwira za K, zabuluu za L, ndi zofiira za M.
Mitundu ya K ndi L ndi yoyenera pa ntchito zopanikizidwa, monga kugwiritsa ntchito ma compressor a mpweya ndi kutumiza gasi wachilengedwe ndi LPG (K kwa pansi pa nthaka, L kwa mkati) . Mitundu itatu yonse ndi yoyenera madzi apanyumba (Mtundu wa M wokonda), wogwiritsira ntchito mafuta ndi mafuta amafuta (Mtundu L, wokonda), ntchito za HVAC (Mtundu L, wokonda), ma unit vacuum, ndi zina zambiri.
Ma chubu ogwiritsira ntchito ngalande, zinyalala ndi zotulutsa mpweya zimakhala zocheperako ndipo zimakhala ndi mphamvu zochepa. Zimapezeka mumiyeso yodziwika kuchokera ku 1-1 / 4 mpaka 8 mainchesi ndi mtundu wachikasu wachikasu. Imapezeka muutali wowongoka wa 20-foot, koma utali wamfupi nthawi zambiri umakhala wodzaza.
Machubu omwe amagwiritsidwa ntchito kusamutsa mpweya wamankhwala ndi mtundu wa K kapena mtundu wa L wokhala ndi zofunikira zaukhondo wapadera.Mafuta omwe amagwiritsidwa ntchito popanga machubu ayenera kuchotsedwa kuti asawotche pamaso pa mpweya komanso kuonetsetsa kuti thanzi la wodwalayo.Machubu nthawi zambiri amatsekedwa ndi kutsekedwa pambuyo poyeretsa ndi kutsekedwa pansi pa nitrogen purge panthawi yoika.
Machubu omwe amagwiritsidwa ntchito popanga mpweya ndi firiji amasankhidwa ndi OD yeniyeni, yomwe ili yosiyana ndi gulu ili.Miyeso imachokera ku 3 / 8 mpaka 4-1 / 8 mainchesi kuti ikhale yowongoka komanso 1 / 8 mpaka 1-5 / 8 mainchesi kwa ma coils. Zonsezi, machubuwa ali ndi chiwerengero chapamwamba cha kupanikizika kwa mainchesi omwewo.
Machubu amkuwa amapezeka m'mitundu yosiyanasiyana yopangira ntchito zapadera. Machubu amkuwa a Beryllium amatha kuyandikira mphamvu ya machubu azitsulo, ndipo kukana kutopa kwake kumapangitsa kuti ikhale yothandiza kwambiri pazinthu zapadera, monga machubu a Bourdon. Aloyi ya nickel-copper-nickel imalimbana kwambiri ndi dzimbiri lamadzi a m'nyanja, ndipo kukula kwa tubing kumagwiritsidwa ntchito nthawi zambiri pakukula kwa Nick bar. 90/10, 80/20 ndi 70/30 ndi mayina odziwika pa zinthuzi.OFHC kapena machubu amkuwa opanda okosijeni amagwiritsidwa ntchito kwambiri popanga ma waveguide ndi zina zotero.Machubu amkuwa ovala Titaniyamu atha kugwiritsidwa ntchito posinthanitsa ndi kutentha kowononga.
Monga tanena kale, mapaipi amkuwa amalumikizidwa mosavuta pogwiritsa ntchito njira zowotcherera komanso zowotcherera. Ngakhale njirazi ndizokwanira komanso zosavuta kugwiritsa ntchito monga madzi apanyumba, kutentha kumapangitsa kuti chubu chokokedwa, chomwe chimachepetsa kuthamanga kwake. Pali njira zingapo zamakina zomwe sizisintha mawonekedwe a chubu. zinthu zomwe kugwiritsa ntchito malawi kapena kutentha sikuli kotetezeka.Ubwino wina ndi wakuti ena mwa mawotchiwa amatha kuchotsa mosavuta.
Njira ina, yomwe imagwiritsidwa ntchito pazochitika zomwe nthambi zambiri zimayenera kutuluka mu chitoliro chimodzi chachikulu, ndikugwiritsa ntchito chida cha extrusion kuti apange chotulukira mwachindunji mu chitoliro.Njirayi imafuna brazing ya kugwirizana komaliza, koma sikutanthauza kugwiritsa ntchito zida zambiri.
Nkhaniyi ikufotokoza mwachidule mitundu ya mapaipi amkuwa.Kuti mumve zambiri pazamankhwala ena, chonde onaninso maupangiri athu ena kapena pitani ku Thomas Supplier Discovery Platform kuti mupeze magwero operekera kapena kuti muwone zambiri zamalonda.
