Ngaba iShedyuli 40 Pipe ifanelekile kwizicelo zesakhiwo?

Ukuphanda Ukubaluleka kwe-SCH 40 kuLwakhiwo lweNsimbi

Umbhobho weShedyuli 40 wamkelwe ngokubanzi njengosetyenziswa rhoqo kwaye onokuziqhelanisa kakhuluuhlobo lwe-eumbhobho wentsimbi yekhabhonikwicandelo lentsimbi.Nangona kunjalo, kuvela umbuzo phakathi kweenjineli, abathengi kunye nabakhi: Ngaba umbhobho weShedyuli 40 ufanelekile ngeenjongo zokwakha?

Eli nqaku liza kuhlola ukusetyenziswa kweShedyuli 40 kwaye liqwalasele ukubaluleka kwayo kwiimeko zesakhiwo.

Ukuqonda ukuba yintoni "Ishedyuli 40"
IShedyuli 40 ayibonisi mgangatho wezinto okanye iinkcukacha zokuqina—ibhekisa kubukhulu bodonga lombhobho olandelayoI-ASME/ASTMizikhokelo ezinobukhulu obuhlukeneyo.

Kwitheyibhile esiyibonayo, umbhobho we-Schedule 40 wee-intshi ezi-2 unobukhulu bodonga obuyi-3.91 mm, ngelixa umbhobho we-8 intshi ulinganisa i-8.18 mm. Ezi milinganiselo zimiselwe yi-ASME B36.10M, eyenzelwe ikakhulu imibhobho yoxinzelelo kwiinkqubo zokuhambisa ulwelo.

Yenzelwe uxinzelelo, kungekhona imithwalo yesakhiwo

Imibhobho yeShedyuli 40 idla ngokuveliswa ngokwemigangatho efana ne-ASTM A53, ASTM A106, okanyeI-API 5LEzi nkcukacha zigxininisa ukuxinana koxinzelelo, ukudityaniswa, kunye nokumelana nokugqwala, endaweni yomthamo wolwakhiwo.

Oku kuthetha ukuba imibhobho yenzelwe ukumelana noxinzelelo lwangaphakathi, kungekhona ngamandla angaphandle afana nokugoba okanye ukucinezelwa kwizakhelo zesakhiwo.

Ngaba kunokwenzeka ukuba kusetyenziswe ulwakhiwo?

Ewe—nangona kukho imiqathango ethile.

Umbhobho weShedyuli 40 ungasetyenziswa kwiiprojekthi zesakhiwo ezikhaphukhaphu okanye ezingabalulekanga kangako, ngakumbi kwizicelo ezifana nezi:

- Izikhonkwane zokukhusela, ucingo, kunye nezikhonkwane zokuxhasa

- Iifreyimu zenkxaso kunye neeyunithi zeeshelufu

- Izithuba zemiqondiso kunye neendibano ezincinci ze-truss

Kwezi meko, iShedyuli 40 lukhetho olungabizi kakhulu ngenxa yokuba lunamandla aneleyo kwizicelo ezingabalulekanga kwaye lufumaneka ngokubanzi.

Nangona kunjalo, xa sikhetha iimveliso zezakhiwo ezithwala umthwalo okanye izinto ezikwiindlela zobunjineli eziqinisekisiweyo kunye nezakhiwo, kufuneka kukhethwe imibhobho yentsimbi yodidi oluphezulu efana ne-ASTM A500 okanye i-ASTM A252 endaweni yoko. Kuba ezi zenzelwe ngokukodwa ukuqina kwezakhiwo kwaye zivavanywa ukusebenza koomatshini.

Ukuthelekisa iShedyuli 40 kunye ne-ASTM A500 Structural Tubing

Njengoko itheyibhile ibonisa, xa kukho imfuneko yamandlah, ukunyamezelana okufanayo, kunye nokusebenza rhoqo phantsi komthwalo, ukhetho olungcono yi-ASTM A500.

Iingcinga Zokugqibela

Ishedyuli 40 yemibhobho iyaqhubekaIza kuba lolunye lweentlobo zeepayipi zentsimbi ezisetyenziswa kakhulu nezingabizi kakhulu ezikhoyo. Igqwesile kwiinkqubo zolwelo, ukwenziwa ngokubanzi, kunye nemisebenzi elula yokwakha.

Nangona kunjalo, kubalulekile ukukhetha umbhobho wesinyithi okanye iityhubhu eziqinisekisiweyo (ezifana ne-ASTM A500 okanye i-A252) kwiiprojekthi ezifuna ukuthembeka kwesakhiwo esenziwe ngobunjineli.

Oku akuqinisekisi nje kuphela ukuthotyelwa kwemithetho yoyilo, kodwa kunye nokhuseleko lwexesha elide kunye nokusebenza kweprojekthi yakho.

I-TianjinYuantai DerunI-Steel Pipe Group ngumthengisi othembekileyo weepayipi zentsimbi zeSchedule 40 kunye neetyhubhu zesakhiwo ze-ASTM A500, enikezela ngeemveliso ezipheleleyo kunye nesatifikethi sovavanyo lwe-mill kubathengi abathumela kwamanye amazwe kwihlabathi liphela.
