Ndondomeko ya mapaipi imawonetsa makulidwe a khoma ndi malire a kuthamanga kwa madzi. Nambala iliyonse imayimira makulidwe enaake a khoma. Mainjiniya amagwiritsa ntchito manambalawa popanga njira zotetezera komanso zogwira mtima zoyendetsera mapaipi.
Ndondomeko 40 ili ndi makoma opyapyala kuposa Ndondomeko 80. Imagwirizana ndi makina omwe ali ndi mphamvu zochepa.
Makoma a Ndandanda 80 ndi okhuthala kuposa Ndandanda 40. Amatha kuthana ndi kupanikizika kwakukulu ndipo amakhala nthawi yayitali. Kusankha ndondomeko yoyenera kumateteza kutuluka kwa madzi, kuphulika, komanso kulephera msanga.
Kukhuthala kwa khoma kumakhudza mphamvu, kuyenda, ndi kuyika. Mapaipi okhala ndi mulifupi wofanana koma nthawi zosiyanasiyana amachita mosiyana.
Chitoliro cha SCH 40 chili ndi kulemera kopepuka, zomwe zimapangitsa kuti kugwiritsa ntchito ndi kuyika kukhale kosavuta. Chimachepetsanso nthawi yoyika.
Chitoliro cha SCH 80 chimapereka mphamvu zambiri, ngakhale kuti makulidwe ake ochulukirapo a khoma amachititsa kuti chikhale cholemera kwambiri. Kuchichirikiza bwino ndi kuchisamalira mosamala n'kofunika kuti tipewe kuwonongeka.
Kusankha mapaipi achitsulo cha kaboni kuyenera kuganizira mtundu wa madzi ndi zofunikira pa makina. Mapaipi operekera madzi, machitidwe a HVAC, ndi maukonde otulutsira madzi nthawi zambiri amadalira mapaipi a SCH 40.
Imayesa mtengo, kulemera, ndi mphamvu ya kupanikizika. Mapaipi a mankhwala, mizere ya nthunzi ya mafakitale, ndi mapaipi amphamvu kwambiri amapindula ndi mapaipi a SCH 80. Makoma ake okhuthala amalimbana ndi kukokoloka kwa nthaka, dzimbiri, ndi kupsinjika kwa makina.
Kumene SCH 40 ndi SCH 80 Zimagwiritsidwa Ntchito
Chitoliro cha Schedule 40 chimapezeka kwambiri m'nyumba, m'mabizinesi, komanso m'mafakitale opepuka. Kulemera kochepa kwa chitoliro cha SCH 40 kumapangitsa kuti chizigwiritsidwa ntchito mosavuta panthawi yonyamula ndi kuyika. Kukhuthala kwa khoma lake kumathandiza kuti chizigwiritsidwa ntchito pang'ono mpaka pang'ono pomwe chimakhala chogwiritsidwa ntchito bwino poyika.
Mainjiniya ambiri amakonda chitoliro cha SCH 80 cha mafakitale opanga mankhwala, mapaipi amphamvu kwambiri, ndi machitidwe a mafakitale. Chimalimbana ndi kuwonongeka, dzimbiri, ndi kupsinjika kwakukulu. Kutumiza nthunzi, mizere ya mankhwala, ndi mapaipi akutali nthawi zambiri amasankha SCH 80 kuti atsimikizire kudalirika.
Kutentha, mtundu wa madzi, ndi kuthamanga kwa madzi zimakhudza kusankha nthawi. Mizere ya nthunzi yotentha nthawi zambiri imagwiritsa ntchito chitoliro cha SCH 80 kuti ipewe kusintha kwa madzi. Mizere ya mapaipi amadzi ozizira ingagwiritse ntchito chitoliro cha SCH 40 mosamala.
Kusankha zinthu n'kofunikanso. Chitsulo chosapanga dzimbiri SCH 80 chimapereka kukana dzimbiri kwinaku chikusunga mphamvu ya kuthamanga kwa madzi. Kukonzekera bwino kumachepetsa ndalama zokonzera ndikuwonjezera nthawi yogwira ntchito ya mapaipi.
Kuchuluka kwa madzi ndi kukula kwa madzi mkati mwake ndi zinthu zofunika kuziganizira. Kapangidwe ka khoma lopyapyala la Sceedule 40 Carbon Steel Pipe kamapereka kukula kwa madzi mkati mwake, zomwe zimathandiza kuti madzi aziyenda bwino. Chitoliro cha Schedule 80 chimachepetsa kukula kwa madzi mkati mwake pang'ono, zomwe zimakhudza liwiro la madzi.
Mainjiniya amawerengera kuchepa kwa mphamvu ya mpweya ndi momwe madzi amayendera bwino pa ntchito iliyonse. Kusankha nthawi yoyenera ya chitoliro kumathandiza kuonetsetsa kuti ntchito ikuyenda bwino. Zimathandizanso miyezo yachitetezo ndikusunga ndalama mu HVAC, madzi, ndi mapaipi a mankhwala.
Kuyerekeza SCH 40 ndi SCH 80
Kusiyana kwakukulu pakati pa makoma ndi makulidwe awo. Makoma a SCH 80 ndi okhuthala, zomwe zimapangitsa kuti mphamvu yamagetsi ikhale yolimba komanso yolimba. Makoma okhuthala amachepetsa pang'ono kukula kwa mkati, zomwe zimakhudza kuyenda kwa madzi.
Chitoliro cha SCH 40 cha mainchesi awiri nthawi zambiri chimatha kugwira ntchito pafupifupi psi 280. Chitoliro cha SCH 80 cha kukula komweko chimatha kugwira ntchito pafupifupi psi 400. Chitoliro cha SCH 80 chimakhala ndi kulemera kwakukulu ndipo nthawi zambiri chimakhala ndi mtengo wokwera wa zinthu.
Kukhazikitsa kumafuna zothandizira zolimba. Zolumikizira zimatsatira malamulo omwewo a nthawi. Zolumikizira mapaipi zopangidwa motsatira miyezo ya SCH 80 zimathandiza kupanikizika kwakukulu kwa ntchito.
Ma schedule onsewa amabwera mu chitsulo cha kaboni, chitoliro chachitsulo chosapanga dzimbiri, ndi chitoliro cha PVC. Kusankha kuphatikiza koyenera kumatsimikizira chitetezo, kudalirika, komanso kutsatira miyezo yamafakitale.
Zofunikira pakuwunikanso zimasiyana. Makina a mapaipi a Schedule 80 adapangidwa kuti azigwira ntchito kwa nthawi yayitali komanso pafupipafupi yowunikira. Chitoliro cha SCH 40 chingafunike kuyang'aniridwa pafupipafupi m'malo ovuta. Mainjiniya amaganizira izi akamakonzekera nthawi yokonza ndi ndalama zomwe zimafunika pa moyo wawo wonse.
Malangizo Okhazikitsa
Chitoliro cha Schedule 40 n'chosavuta kudula, kulumikiza, ndi kuchirikiza chifukwa n'chopepuka. Chitoliro cha Howevr SCH 80 chimafuna zida zapadera zodulira ndi kulumikiza.
Kukhazikika bwino ndi chithandizo zimateteza kugwedezeka kapena kupsinjika. Kukula kwa kutentha ndi chinthu chofunikira kuganizira pa kapangidwe kake. Chitoliro cha SCH 80 chimalimbana ndi kusintha kwa kutentha, koma malo olumikizirana angafunikebe.
Kukhazikitsa bwino kumawonjezera chitetezo cha makina. Kumathandiza kukulitsa moyo wonse wa makinawo. Kuyenda kwa madzi kumakhala kokhazikika mu makina operekera madzi, HVAC, ndi mapaipi a mankhwala.
