Chitoliro cha ASTM A53 Ndondomeko 40ndi chitoliro chachitsulo cha kaboni chogwirizana ndi A53 chokhala ndi kuphatikiza kwapadera kwa mainchesi akunja ndi makulidwe a khoma.
Amagwiritsidwa ntchito kwambiri m'mapulojekiti osiyanasiyana a uinjiniya ndi zomangamanga, makamaka pantchito monga kunyamula zakumwa, mpweya, ndi nthunzi.
Kusiyana kwakukulu pakati pa chitoliro chachitsulo cha ASTM A53 ndimtundu wa mapeto a chitoliro, makamaka pankhani ya Ndandanda 40.
Mapeto a mapaipi a ASTM A53 akhoza kugawidwa m'magulu awiri:Chitoliro Chopanda Mapeto, Chitoliro Cholumikizidwa ndi Cholumikizidwa.
Ndondomeko 40 ya ASTM A53 ya Chitoliro Chopanda Malire
Malekezero ake amadulidwa molunjika komanso molunjika ku chubu kuti athe kulumikizana ndi zolumikizira zolumikizira kapena zolumikizira.
Machubu a Flat-end Schedule 40 nthawi zambiri amagwiritsidwa ntchito pa ntchito zotentha kwambiri komanso zopanikiza zomwe zimafuna maulumikizidwe olumikizidwa kuti ateteze mphamvu ndi kutayikira kwa madzi. Izi zimaphatikizapo makina opangira mapaipi m'mafakitale oyeretsera, malo opangira magetsi, ndi malo ena amafakitale.
Malekezero athyathyathya a chubu amathanso kupangidwa ndi makina pamalo opindika kuti zikhale zosavuta kuwotcherera. Kulemera kwapadera kwa malekezero opindika kungatchulidwenso ngati deta ya kulemera kwa malekezero athyathyathya chifukwa kudzachepetsedwa pang'ono pokonza malekezero opindika.
Ubwino wa malekezero athyathyathya:
Yabwino kwambiri polumikiza ndi kupanga malo olimba komanso osatulutsa madzi.
Yoyenera kugwiritsidwa ntchito pa kutentha kwambiri komanso pa kuthamanga kwambiri.
Amapereka kulumikizana kosalala popanda kusweka kwamkati, kuchepetsa kutsika kwa kuthamanga ndi kugwedezeka.
Ndondomeko ya ASTM A53 40 ya Chitoliro Cholumikizidwa ndi Cholumikizidwa
Machubu olumikizirana okhala ndi ulusi amapangidwira ntchito zomwe kulumikizana kosavuta kungapangidwe popanda kuwotcherera. Ulusi womwe uli kumapeto kwa chubu umalola kuti zigawozo zilumikizidwe mozungulira, nthawi zambiri pogwiritsa ntchito zolumikizira.
Izi ndi zabwino makamaka pamene ntchito zowotcherera sizimayesedwa mosavuta kapena pamene pakufunika kusokoneza pafupipafupi.
Cholumikizira ndi cholumikizira chomwe chimagwiritsidwa ntchito polumikiza malekezero awiri a mapaipi okhala ndi ulusi. Zolumikizira nthawi zambiri zimakhala zozungulira zokhala ndi ulusi wamkati womwe umagwirizana ndi ulusi wa malekezero a mapaipi. Zikayikidwa, malekezero a ulusi wa mapaipi awiriwa amakulungidwa mbali zonse ziwiri za cholumikizira kuti apange cholumikizira.
Kusankha ulusi ndi malekezero a mapaipi olumikizira kuyenera kuganizira zofunikira zenizeni zogwiritsira ntchito, kuphatikizapo kuthamanga, kutentha, ndi mtundu wa madzi a malo ogwirira ntchito.
Ubwino:
Kukhazikitsa mwachangu komanso kosavuta: sikufunika kuwotcherera, zomwe zimapangitsa kuti kukhazikike mwachangu pamalopo.
Zosavuta kusamalira ndi kusintha: zigawo zowonongeka zitha kuchotsedwa mosavuta ndikusinthidwa.
Yotsika mtengo: nthawi zambiri imakhala yotsika mtengo poyerekeza ndi mapaipi omwe amafunika kuwotcherera.
Zoyipa:
Kuchepa kwa kuthamanga ndi kutentha: maulumikizidwe okhala ndi ulusi sangakhale oyenera kugwiritsidwa ntchito ndi kuthamanga kwambiri kapena kutentha kwambiri poyerekeza ndi maulumikizidwe olumikizidwa.
Kuopsa kotaya madzi: Ngati ulusi suli wolimba mokwanira kapena womasuka chifukwa cha kutha, pakhoza kukhala chiopsezo chotaya madzi.
Ndondomeko 40 ya ASTM A53 imagwiritsidwa ntchito kwambiri
Chitoliro chachitsulo cha ASTM A53 ndi chitoliro chachitsulo cha kaboni chomwe chimagwiritsidwa ntchito kwambiri. Chimakhala ndi mitundu yambiri ya machubu opanda msoko, osasunthika, komanso opindika m'chiuno.
Chitoliro chachitsulo cha ASTM A53 ndi cholimba, chogwiritsidwa ntchito m'njira zosiyanasiyana, komanso chotsika mtengo, zomwe zimapangitsa kuti chikhale chofunikira kwambiri m'mafakitale ambiri. Chimagwiritsidwa ntchito m'njira zosiyanasiyana, kuyambira pakupanga zomangamanga mpaka kugwiritsa ntchito mafakitale.
Kugwiritsa ntchito kwambiri chitoliro chachitsulo cha Schedule 40 kumachokera ku magwiridwe ake abwino kwambiri, kugwiritsa ntchito bwino ndalama, kugwiritsidwa ntchito bwino, kusavuta kukonzedwa, komanso kutsatira malamulo okhwima okhudza ukonde. Zinthu zonsezi zapangitsa Schedule 40 kukhala chinthu chodziwika bwino m'mafakitale, zomangamanga, ndi madera ena ambiri.
Kuphatikiza kwa mphamvu zimenezi ndi chifukwa chake ntchito ndi ubwino wa ASTM A53 Schedule 40 m'makampaniwa zakulitsidwa kwambiri.
Kugwiritsa Ntchito Mwanzeru
Makampani amafuta ndi gasi: Pakuboola mafuta ndi kutulutsa gasi wachilengedwe, chitoliro chachitsulo cha ASTM A53 Schedule 40 chimagwiritsidwa ntchito popanga mizere yotumizira mafuta ndi gasi yotsika mpaka yapakati.
Machitidwe operekera madzi: Amagwiritsidwa ntchito kwambiri m'mizere yoperekera madzi m'matauni. Kudalirika kwake kumatsimikizira ubwino wa madzi kwa nthawi yayitali komanso chitetezo cha madzi.
Kutumiza mpweya wachilengedweMofananamo, chitolirochi chimagwiritsidwa ntchito m'maukonde ogawa gasi wachilengedwe, komwe mphamvu zake ndi miyezo yake yachitetezo zimakwaniritsa zofunikira zolimba za makampani opanga mphamvu.
Kumanga nyumba: Mu nyumba zamalonda ndi zogona, imagwiritsidwa ntchito popanga mafelemu othandizira, matabwa ndi zipilala.
Kutentha, mpweya wabwino ndi zoziziritsira mpweya (HVAC): ingagwiritsidwe ntchito mu makina a HVAC ponyamula zinthu zotenthetsera kapena zoziziritsira, ndipo mphamvu zake zotsutsana ndi kuthamanga kwa mpweya ndi kutentha ndizoyenera kugwiritsa ntchito mtundu uwu wa magetsi.
Makampani opanga mankhwala: Amagwiritsidwa ntchito m'mafakitale opanga mankhwala ponyamula mankhwala owononga. Kukhazikika kwa kapangidwe kake kumachepetsa chiopsezo cha kutuluka kwa madzi ndikuwonjezera chitetezo cha zomera.
Uinjiniya wamagalimoto ndi makina: machubu awa amagwiritsidwanso ntchito pakupanga, pa kayendedwe ka gasi ndi madzi, komanso ngati zida zomangira makina.
Zogulitsa Zathu Zofanana
Ndife opanga mapaipi achitsulo cha kaboni opangidwa ndi zitsulo komanso ogulitsa mapaipi apamwamba ochokera ku China, komanso ogulitsa mapaipi achitsulo osasokonekera, omwe amakupatsirani mitundu yosiyanasiyana ya njira zothetsera mapaipi achitsulo!
