Yintoni umahluko phakathi kwePipe kunye neTube?

Abantu basebenzisa amagama umbhobho kunye netyhubhu ngokutshintshanayo, kwaye bacinga ukuba zombini ziyafana. Nangona kunjalo, kukho umahluko omkhulu phakathi kombhobho kunye ne-tube.

Impendulo emfutshane yile: I-PIPE yi-tubular engqukuva yokusasaza ulwelo kunye neegesi, ezikhethwe ngubungakanani bombhobho obizwa ngokuba yi-NPS okanye i-DN emele isalathiso esirhabaxa somthamo wokuhambisa umbhobho; I-TUBE licandelo elingqukuva elingqukuva, elixande, elisisikwere okanye elimbhoxo elilinganiswa nedayamitha yangaphandle (OD) kunye nobukhulu bodonga (WT), ebonakaliswa ngee-intshi okanye iimilimitha.

Yintoni uMbhobho?

Umbhobho licandelo elingenanto kunye necandelo elijikelezayo elijikelezayo lokuhanjiswa kweemveliso. Iimveliso ziquka ulwelo, irhasi, iipellets, umgubo kunye nokunye.

Imilinganiselo ebaluleke kakhulu yombhobho yi-diameter yangaphandle (OD) kunye nobukhulu bodonga (WT). OD thabatha 2 amaxesha WT (ishedyuli) misela i-diameter yangaphakathi (ID) yombhobho, omisela umthamo wamanzi wombhobho.

Imizekelo ye-OD yangempela kunye ne-ID

Iidayamitha zangaphandle eziyinyani

• NPS 1 eyona OD = 1.5/16″ (33.4 mm)
• NPS 2 eyona OD = 2.3/8″ (60.3 mm)
• NPS 3 eyona OD = 3½” (88.9 mm)
• NPS 4 eyona OD = 4½” (114.3 mm)
• NPS 12 eyona OD = 12¾” (323.9 mm)
• NPS 14 eyona OD = 14″ (355.6 mm)

Okwenene ngaphakathi kweedayamitha zombhobho we-intshi eyi-1.

• I-NPS 1-SCH 40 = OD33,4 mm - WT. 3,38 mm - ID 26,64 mm
• I-NPS 1-SCH 80 = OD33,4 mm - WT. 4,55 mm - ID 24,30 mm
• I-NPS 1-SCH 160 = OD33,4 mm - WT. 6,35 mm - ID 20,70 mm

Njengokuchaziweyo ngasentla, i-diameter yangaphakathi imiselwa yi-oudside diameter (OD) kunye nobukhulu bodonga (WT).

Iiparamitha ezibaluleke kakhulu zoomatshini kwimibhobho yinqanaba loxinzelelo, amandla esivuno, kunye ne-ductility.

Iindibaniso ezisemgangathweni zombhobho Ubungakanani bombhobho oLungileyo kunye noButyebi beDonga (ishedyuli) igutyungelwe yinkcazo ye-ASME B36.10 kunye ne-ASME B36.19 (ngokulandelelanayo, imibhobho yekhabhoni kunye nealloy, kunye nemibhobho yensimbi engenasici).

Yintoni iTube?

Igama elithi TUBE libhekisa kumacandelo angqukuva, asisikwere, uxande kunye nombhoxo asetyenziselwa izixhobo zoxinzelelo, usetyenziso loomatshini, kunye neenkqubo zesixhobo.

Iibhubhu ziboniswa ngedayimitha yangaphandle kunye nobukhulu bodonga, ngee-intshi okanye ngeemilimitha.

Umbhobho vs Tube, 10 umahluko osisiseko

PIPE vs TUBE	UMbhobho wentsimbi	ityhubhu yentsimbi
Imilinganiselo engundoqo (iTshati yoMbhobho kunye nobungakanani beTubhu)	Imilinganiselo ebaluleke kakhulu yombhobho yi-diameter yangaphandle (OD) kunye nobukhulu bodonga (WT). I-OD thabatha amaxesha ama-2 WT (ISHEDYULI) imisela i-diameter yangaphakathi (ID) yombhobho, omisela umthamo wolwelo wombhobho. I-NPS ayihambelani nobukhulu bokwenyani, luphawu olurhabaxa	Imilinganiselo ebaluleke kakhulu kwityhubhu yensimbi yi-diameter yangaphandle (OD) kunye nobukhulu bodonga (WT). Ezi parameters zibonakaliswa ngee-intshi okanye iimilimitha kwaye zivakalisa ixabiso lokwenyani ledimensional yecandelo elinomqolo.
Ukutyeba kweendonga	Ubunzima bombhobho wensimbi butyunjwe ngexabiso "iShedyuli" (ezona ziqhelekileyo ziyi-Sch. 40, Sch. STD., Sch. XS, Sch. XXS). Imibhobho emibini ye-NPS eyahlukileyo kunye neshedyuli efanayo inobunzima obuhlukeneyo bodonga ngee-intshi okanye iimilimitha.	Ubunzima bodonga lombhobho wensimbi bubonakaliswa ngamasentimitha okanye iimilimitha. Kwityhubhu, ubukhulu bodonga bulinganiswa ne-nomenclature ye-gage.
Iindidi zeMibhobho kunye neMibhobho (iiMilo)	Umjikelo kuphela	Round, uxande, square, oval
Uluhlu lwemveliso	Lubanzi (ukuya kuthi ga kwi-intshi ezingama-80 nangaphezulu)	Uluhlu olucutheneyo lwetyhubhu (ukuya kuthi ga kwi-intshi ezi-5), ezinkulu kwiityhubhu zentsimbi ezisetyenziselwa oomatshini.
Ukunyamezela (ukuqina, imilinganiselo, ukujikeleza, njl njl) kunye nePipe vs	Ukunyamezela kubekwe, kodwa kunokuba kukhululekile. Amandla ayona nto ixhalabisayo.	Iityhubhu zentsimbi ziveliswa kukunyamezela okungqongqo kakhulu. Ii-tubulars ziye zijongwe umgangatho womgangatho oliqela, njengokuthi tye, ukujikeleza, ubukhulu bodonga, umphezulu, ngexesha lenkqubo yokuvelisa. Amandla omatshini yinkxalabo enkulu yeetyhubhu.
Inkqubo yeMveliso	Imibhobho iqhele ukwenziwa isitokhwe ngeenkqubo ezizisebenzelayo nezisebenzayo, okt.	Ukwenziwa kweetyhubhu kuthatha ixesha elide kwaye kunzima
Ixesha lokuzisa	Inokuba mfutshane	Ngokubanzi ixesha elide
Ixabiso lemarike	Ixabiso eliphantsi ngokwetoni nganye kuneityhubhu zentsimbi	Ephakamileyo ngenxa yemveliso ephantsi yokugaya ngeyure, kwaye ngenxa yeemfuno ezingqongqo ngokunyamezela kunye nokuhlolwa
Izinto eziphathekayo	Uluhlu olubanzi lwezinto ezikhoyo	I-tubing ifumaneka kwi-carbon steel, i-alloy ephantsi, insimbi engenasici, kunye ne-nickel-alloys; iityhubhu zentsimbi ukwenzela ukusetyenziswa koomatshini ubukhulu becala yintsimbi yekhabhoni
Phelisa uQhagamshelwano	Ezona zixhaphakileyo ziziphelo ezibeveled, ezicacileyo nezikruwe	Iziphelo ezinemisonto kunye ne-grooved ziyafumaneka ukuze uqhagamshelo olukhawulezayo kwisiza
