Ukuphenya Ukubaluleka kwe-SCH 40 ekwakhiweni kwensimbi
Ipayipi le-Schedule 40 ngokuvamile lamukelwa njengepayipi elisetshenziswa njalo futhi elivumelana nezimo kakhuluuhlobo lwe-eipayipi lensimbi yekhabhoniemkhakheni wensimbi.Kodwa-ke, kuvela umbuzo phakathi konjiniyela, abathengi, nabakhi: Ingabe ipayipi le-Schedule 40 lifanelekela izinjongo zokwakha?
Lesi sihloko sizohlola ukusetshenziswa kweSheduli 40 futhi sicabangele ukubaluleka kwayo ezimweni zesakhiwo.
Ukuqonda ukuthi kuyini “Ishejuli 40"
Isikhundla seShejuli 40 asibonisi izinga lezinto ezibonakalayo noma incazelo yamandla—sibhekisela ekujiyeni kodonga lwepayipi okulandelayoI-ASME/ASTMiziqondiso zobukhulu.
Kusukela etafuleni esingabona, ipayipi le-Schedule 40 elingamasentimitha angu-2 linobukhulu bodonga obungu-3.91 mm, kanti ipayipi elingamasentimitha angu-8 lilinganisa u-8.18 mm. Lezi zilinganiso zilinganiswa yi-ASME B36.10M, ehloselwe kakhulu amapayipi okucindezela ezinhlelweni zokuhambisa uketshezi.
Yenzelwe Ukucindezela, Hhayi Imithwalo Yesakhiwo
Amapayipi eShejuli 40 avame ukukhiqizwa ngokwezindinganiso ezifana ne-ASTM A53, ASTM A106, nomaI-API 5LLezi zincazelo zigcizelela ukugcinwa kwengcindezi, ukushintshwa, kanye nokumelana nokugqwala, kunokuba kube namandla okwakheka.
Lokhu kusho ukuthi amapayipi aklanyelwe ukumelana nengcindezi yangaphakathi, hhayi ngempela amandla angaphandle njengokugoba noma ukucindezela ezinhlakeni zesakhiwo.
Ingabe Ukusetshenziswa Kwesakhiwo Kungenzeka?
Yebo—nakuba kunemingcele ethile.
Ipayipi leShejuli 40 lingasetshenziswa kumaphrojekthi esakhiwo alula noma angabalulekile, ikakhulukazi ezinhlelweni ezifana nalezi:
- Izinsika zokuvikela, uthango, kanye nezinsika zokuvikela
- Ozimele abasekelayo namayunithi okubeka amashalofu
- Izigxobo zezimpawu kanye nezindawo zokuhlanganisa izintambo ezincane
Kulezi zimo, iShejuli 40 iyindlela engabizi ngenxa yamandla ayo anele ezinhlelo zokusebenza ezingabalulekile kanye nokutholakala kwayo kabanzi.
Noma kunjalo, lapho sikhetha imikhiqizo yezakhiwo ezithwala umthwalo noma izingxenye ngaphakathi kwemiklamo yobunjiniyela eqinisekisiwe kanye nesakhiwo, kufanele kukhethwe amapayipi ensimbi asezingeni eliphezulu njenge-ASTM A500 noma i-ASTM A252 esikhundleni salokho. Ngoba lawa aklanywe ngokukhethekile ukuze kube sezingeni eliphezulu futhi ahlolwe ukusebenza kahle kwemishini.
Ukuqhathanisa iShejuli 40 kanye ne-ASTM A500 Structural Tubing
Njengoba ithebula libonisa, lapho kunesidingo samandlah, ukubekezelelana okufanayo, kanye nokusebenza okuqhubekayo ngaphansi komthwalo, ukukhetha okungcono yi-ASTM A500.
Imicabango Yokugcina
Iphayiphi yeShejuli 40 iyaqhubekaKuzoba ngenye yezinhlobo zamapayipi ensimbi asetshenziswa kabanzi futhi angabizi kakhulu atholakalayo. Ihamba phambili ezinhlelweni zoketshezi, ukwenziwa okuvamile, kanye nemisebenzi yesakhiwo elula.
Kodwa-ke, kubalulekile ukukhetha ipayipi lensimbi noma ipayipi eliqinisekisiwe lesakhiwo (njenge-ASTM A500 noma i-A252) kumaphrojekthi adinga ukuthembeka kwesakhiwo okwenziwe ngobunjiniyela.
Lokhu akuqinisekisi nje kuphela ukunamathela kumakhodi okuklama, kodwa futhi nokuphepha kwesikhathi eside kanye nokusebenza kwephrojekthi yakho.
I-TianjinI-Yuantai DerunI-Steel Pipe Group ingumhlinzeki othembekile wamapayipi ensimbi e-Schedule 40 kanye namashubhu esakhiwo e-ASTM A500, enikeza imikhiqizo ephelele kanye nesitifiketi sokuhlolwa kwesigayo kumakhasimende athumela kwamanye amazwe emhlabeni jikelele.
Ukuze uthole ulwazi olwengeziwe noma imibuzo, sicela uxhumane nathi—ithimba lethu lobuchwepheshe liyatholakala ukukusiza ekukhetheni insimbi efanele izidingo zakho.
Isikhathi sokuthunyelwe: Okthoba-16-2025
