Kungakhathaliseki ukuthi umusha embonini yamapayipi noma ingxubevange noma usuneminyaka ukubhizinisi, igama elithi "Shejuli 40" alilisha kuwe.Akulona nje igama elilula, i-metric eyinhloko, ngakho-ke ake sijule kancane futhi sithole ukuthi kungani iShejuli 40 idume kangaka!
Yini iSheduli 40
Ipayipi leSheduli 40 iyipayipi enobukhulu obuthile bodonga.Ubukhulu bodonga oluthile buzohluka kuye ngokuthi ububanzi bangaphandle bepayipi.Lokhu kungenxa yokuthi inombolo engemva Kweshejuli ayibhekiseli ngokuqondile kugqinsi oluthile lodonga, kodwa iwukuhlukanisa ngezigaba.
Ifomula yokubala inombolo Yeshejuli iyindlela eyenziwe lula yokulinganisa ubudlelwano phakathi kogqinsi lwepayipi nengcindezi engaphansi kwayo.
Ifomula imi kanje:
Inombolo Yeshejuli = 1000 (P/S)
Pimele ukucindezela kokusebenza komklamo wepayipi, ngokuvamile ku-psi (amaphawundi ngeyintshi yesikwele)
Simelela ukucindezeleka okuncane okuvumelekile kwempahla yepayipi ekushiseni okusebenzayo, futhi ku-psi (amakhilogremu ngentshi yesikwele).
Le fomula ihlinzeka ngohlaka lwethiyori lokuqonda ubudlelwano phakathi kogqinsi lwamapayipi anamanani eshejuli ahlukene kanye nokucindezela okukhulu angamelana nawo ngokuphephile.Empeleni, inani leshejuli yepayipi lichazwe ngaphambilini ngokwezinga.

ukuhlela 40 izinhlobo impahla
Ipayipi leSheduli 40 lingenziwa ngezinto ezihlukahlukene, kufaka phakathi kodwa kungagcini:
Insimbi Yekhabhoni
Isetshenziselwa ukuthutha amanzi kanye nemifudlana yegesi ngaphansi kwengcindezi ephansi kuya emaphakathi.Izibonelo zifaka phakathi ukuthuthwa kwegesi yemvelo namafutha kanye nezinhlelo zokuhlinzeka ngamanzi.
Insimbi engagqwali
Ifanele ukuphathwa nokuthuthwa kwezinto ezonakalisayo, izinhlelo zamanzi ashisayo, nezinqubo ezithile zezimboni ezidinga amazinga okushisa aphezulu.
I-PVC (i-Polyvinyl Chloride)

Kungani iSheduli 40 isetshenziswa kakhulu
Ukuqina Kwezindonga Ezimaphakathi
Amapayipi weSheduli angu-40 anikeza ukujiya kodonga olumaphakathi, okuwenza aqine ngokwanele ukuphatha izinhlelo zokusebenza ezinomfutho ophansi kakhulu kuya omaphakathi kuyilapho kugwenywa izindleko ezingadingekile ezihambisana nezindonga eziwugqinsi.
Intengo Ephansi
Uma kuqhathaniswa namapayipi anezindonga eziqinile njengeSheduli 80, amapayipi eSheduli 40 anikeza izindleko zempahla ephansi ezinhlelweni eziningi kuyilapho ehlangabezana nezidingo zamandla nokuqina.
Uhla Olubanzi Lwezicelo
Ipayipi le-Sheduli 40 lilungele ukusetshenziswa ezinhlelweni zokudlulisa uketshezi ezihlukene, okuhlanganisa ukuphakelwa kwamanzi, ukugeleza kwamanzi, ukufudumeza, ukungena komoya kanye ne-air conditioning (HVAC), ukudluliswa kwegesi yemvelo, nokunye, okuyenza ibe ukukhetha okuthandwayo ezindaweni zokuhlala, ezohwebo, nezimboni. amaphrojekthi.
Kulula ukusebenzisana nokufaka
Ukuqina kwezindonga ezimaphakathi kwenza ipayipi leSheduli 40 kube lula ukuliphatha ngesikhathi sokusika, ukushisela, nokufakwa, kube lula ukwakhiwa.
Ukuqina
Ipayipi leSheduli 40 linikeza ukuvikeleka okuhle kakhulu kwemishini kanye nokumelana nokugqwala ngenxa yokuqina kodonga olumaphakathi, okuvumela ukusebenza isikhathi eside ezindaweni ezahlukahlukene.
Ukuhambisana Namazinga
Ukufakwa kwamapayipi kweSheduli 40 kulandela izindinganiso eziqashelwa umhlaba wonke njenge-American Society for Testing and Materials (ASTM) kanye ne-American Society of Mechanical Engineers (ASME) ukuze kuqinisekiswe ikhwalithi nokusebenza kwayo.
Ukuthola kalula
Ngenxa yokusetshenziswa kwayo kabanzi, amapayipi eSheduli 40 atholakala kakhulu emakethe futhi athengwa kalula ngamasayizi ahlukahlukene kanye nezinto zokwakha.
Ukuhlaziywa okujulile kwamapayipi eSheduli 40 kubonisa ukuthi anikeza ibhalansi ekahle ngokwezindleko, amandla, ukuqina, kanye nokuguquguquka kwesicelo.Lokhu akugcini nje ngokuyenza ibe yingxenye ebalulekile yohlu olubanzi lwamaphrojekthi.Njengoba ukuthuthuka kwezobuchwepheshe kanye namazinga kuvuselelwa njalo, amapayipi eSheduli 40 ngokungangabazeki azoqhubeka esetshenziswa kabanzi emhlabeni wonke ukusekela ukwakhiwa kwengqalasizinda eyengeziwe kanye nokuthuthukiswa kwezimboni.
