Chubu chamkuwa chimapangidwa ndi 99.9% yamkuwa wangwiro ndi zinthu zazing'ono zophatikizika ndipo zimagwirizana ndi zomwe zasindikizidwa za ASTM. Ndizovuta komanso zofewa, zomwe zikutanthauza kuti chitolirocho chatsekedwa kuti chifewetse. Machubu olimba amalumikizidwa ndi zida za capillary. Ma hoses amatha kulumikizidwa m'njira zina, kuphatikiza zolumikizira ndi zoyaka. Onse amapangidwa mwa mawonekedwe a zomangira zopanda msoko. Mapaipi amkuwa amagwiritsidwa ntchito mu mapaipi, HVAC, firiji, gasi wazachipatala, makina oponderezedwa a mpweya ndi machitidwe a cryogenic. Kuphatikiza pa mapaipi amkuwa okhazikika, mapaipi apadera a alloy amapezekanso.
Mawu akuti mapaipi amkuwa ndi osagwirizana. Chopangidwacho chikakulungidwa, nthawi zina chimatchedwa machubu amkuwa chifukwa chimawonjezera kusinthasintha ndikupangitsa kuti zinthuzo zikhale zopindika mosavuta. Koma kusiyana kumeneku sikuli kusiyana kovomerezeka kapena kovomerezeka. Komanso, mapaipi ena owongoka olimba amkuwa nthawi zina amatchedwa mapaipi amkuwa. Kugwiritsa ntchito mawuwa kumatha kusiyana kuchokera kwa ogulitsa ndi ogulitsa.
Mapaipi onse ndi ofanana kupatula kusiyana kwa makulidwe a khoma, ndi K-chubu yokhala ndi makoma okhuthala kwambiri ndipo chifukwa chake imakhala yothamanga kwambiri. Mapaipi awa ndi 1/8 ″ ang'onoang'ono kuposa awiri akunja ndipo amapezeka kukula kwake kuyambira 1/4 mpaka 12 ″, onse okoka (zolimba) ndi annealed (zofewa). Mapaipi awiri okhuthala a khoma amathanso kukulungidwa mpaka mainchesi awiri. Mitundu itatu imayikidwa pamitundu ndi wopanga: wobiriwira kwa K, buluu wa L, ndi wofiira kwa M.
Mitundu ya K ndi L ndiyoyenera kugwiritsa ntchito zokakamiza monga ma compressor a mpweya ndi kutumiza gasi wachilengedwe ndi LPG (K ya mobisa, L yamkati). Mitundu yonse itatu ndiyoyenera kuperekera madzi am'nyumba (mtundu wa M wokonda), kutumiza mafuta ndi mafuta (mtundu wa L womwe umakonda), makina a HVAC (mtundu wa L womwe umawakonda), ntchito za vacuum ndi zina zambiri.
Kukhetsa, zinyalala ndi machubu otulutsa mpweya ali ndi makoma owonda komanso otsika kwambiri. Imapezeka mumitundu yodziwika bwino kuyambira 1-1 / 4 ″ mpaka 8 ″ ndi yachikasu. Imapezeka mu utali wowongoka wa mapazi 20, koma utali wofupika nthawi zambiri umapezeka.
Machubu omwe amagwiritsidwa ntchito kusamutsa mpweya wamankhwala ndi mtundu wa K kapena mtundu wa L wokhala ndi zofunikira zachiyero chapadera. Mafuta omwe amagwiritsidwa ntchito popanga machubu ayenera kuchotsedwa kuti asapse ndi mpweya komanso kuti wodwalayo akhale ndi thanzi labwino. Mapaipi nthawi zambiri amamangika ndi mapulagi ndi zisoti pambuyo poyeretsa ndikumangidwa ndi nitrogen purge pakuyika.
Mipope yomwe imagwiritsidwa ntchito poyendetsa mpweya ndi firiji imasonyezedwa ndi m'mimba mwake weniweni wakunja, zomwe ndizosiyana ndi gulu ili. Kukula kumayambira 3/8 ″ mpaka 4-1/8 ″ pamabala owongoka ndi 1/8″ mpaka 1-5/8″ pamakoyilo. Nthawi zambiri, mapaipi awa amakhala ndi kukakamiza kwakukulu kwa mita imodzi yofanana.
Mipope yamkuwa imapezeka m'mitundu yosiyanasiyana ya ntchito zapadera. Machubu a Beryllium amkuwa amatha kuyandikira kulimba kwa machubu azitsulo zachitsulo, ndipo kutopa kwawo kumawapangitsa kukhala othandiza kwambiri pakugwiritsa ntchito mwapadera monga machubu a Bourdon. Copper-nickel alloy imalimbana kwambiri ndi dzimbiri m'madzi a m'nyanja, ndipo machubu amagwiritsidwa ntchito m'malo am'madzi momwe kukana kukula kwa barnacle ndi phindu lowonjezera. Copper-Nickel 90/10, 80/20 ndi 70/30 ndi mayina wamba pankhaniyi. Machubu amkuwa opanda okosijeni omwe amagwiritsidwa ntchito kwambiri ndi ma waveguide ndi zina zotero. Titaniyamu yokutidwa ndi mkuwa machubu atha kugwiritsidwa ntchito posinthanitsa kutentha kwambiri.
Monga tanena kale, mapaipi amkuwa amalumikizidwa mosavuta pogwiritsa ntchito njira zotenthetsera monga kuwotcherera ndi kuwotcherera. Ngakhale njirazi ndizokwanira komanso zosavuta kugwiritsa ntchito monga madzi apanyumba, kutentha kumapangitsa kuti chitoliro chokokedwacho chiwonjezeke, chomwe chimachepetsa kuthamanga kwake. Pali njira zingapo zamakina zomwe zilipo zomwe sizisintha katundu wa chitoliro. Izi zikuphatikiza zopangira ma flare, grooved fittings, compression fittings ndi push fittings. Njira zomangirira zamakinazi ndizothandiza kwambiri munthawi yomwe kugwiritsa ntchito lawi lamoto kapena kutentha kumakhala kosatetezeka. Ubwino wina ndi wakuti ena mwa makina olumikizirawa ndi osavuta kuchotsa.
Njira ina, yomwe imagwiritsidwa ntchito ngati nthambi zambiri zimayenera kutuluka mu chitoliro chimodzi chachikulu, ndikugwiritsa ntchito chida cha extrusion kuti apange potulukira mwachindunji mu chitoliro. Njirayi imafuna soldering kugwirizana komaliza, koma sikutanthauza kugwiritsa ntchito zopangira zambiri.
Nkhaniyi ikufotokoza mwachidule mitundu ya mapaipi amkuwa. Kuti mumve zambiri pazogulitsa zina, chonde onani maupangiri athu ena kapena pitani ku Thomas Sourcing Platform kuti mupeze komwe kungapezeke kapena kuwona zambiri zamalonda.
