Uyini umehluko phakathi kwePipe neTube?

Abantu basebenzisa amagama ipayipi neshubhu ngokushintshana, futhi bacabanga ukuthi kokubili kuyafana. Nokho, kunomehluko omkhulu phakathi kwepayipi neshubhu.

Impendulo emfushane ithi: IPIPE iyishubhu eyindilinga yokusabalalisa uketshezi namagesi, eqokwe ngosayizi wepayipi elincane (NPS noma i-DN) omele inkomba enzima yomthamo wokudlulisa amapayipi; I-TUBE iyigodi eliyindilinga, elingunxande, eliyisikwele noma eliyisiyingi eliyisiyingi elilinganiswa ngedayamitha yangaphandle (OD) nogqinsi lodonga (WT), oluvezwa ngamayintshi noma amamilimitha.

Yini iPipe?

Ipayipi iyingxenye engenalutho enesiphambano esiyindilinga sokuhanjiswa kwemikhiqizo. Imikhiqizo ihlanganisa uketshezi, igesi, ama-pellets, izimpushana nokunye.

Izilinganiso ezibaluleke kakhulu zepayipi ububanzi bangaphandle (OD) kanye nobukhulu bodonga (WT). OD susa izikhathi ezi-2 WT (uhlelo) nquma ububanzi bangaphakathi (ID) bepayipi, obunquma umthamo wamanzi wepayipi.

Izibonelo ze-OD yangempela kanye ne-ID

Amadayamitha angempela angaphandle

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

Ububanzi bangempela bangaphakathi bepayipi eliyiyintshi elingu-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

Njengoba kuchazwe ngenhla, ububanzi bangaphakathi bunqunywa ububanzi be-oudside (OD) nokuqina kodonga (WT).

Imingcele ebaluleke kakhulu yemishini yamapayipi isilinganiso sokucindezela, amandla esivuno, kanye ne-ductility.

Izinhlanganisela ezijwayelekile zamapayipi Usayizi Wepayipi Lokuqamba kanye Nokuqina Kodonga (ishejuli) imbozwa ukucaciswa kwe-ASME B36.10 kanye ne-ASME B36.19 (ngokulandelana, amapayipi ekhabhoni nawengxubevange, namapayipi ensimbi engagqwali).

Yini iTube?

Igama elithi TUBE lisho izingxenye eziyizigodi eziyindilinga, eziyisikwele, eziwunxande kanye ne-oval ezisetshenziselwa imishini yokucindezela, ukufakwa kwemishini, kanye nezinhlelo zezinsimbi.

Amashubhu aboniswa ngobubanzi obungaphandle nobukhulu bodonga, ngamasentimitha noma ngamamilimitha.

Ipayipi vs Tube, 10 umehluko oyisisekelo

I-PIPE vs TUBE	IPHIPHA LESIBILI	ITHUBHU LESsimbi
Ubukhulu Bokhiye (Ishadi Losayizi Wepayipi kanye Nethubhu)	Izilinganiso ezibaluleke kakhulu zepayipi ububanzi bangaphandle (OD) kanye nobukhulu bodonga (WT). I-OD khipha izikhathi ezi-2 i-WT (ISHEDULI) inquma ubukhulu bangaphakathi (ID) bepayipi, obunquma umthamo woketshezi wepayipi. I-NPS ayifani nobubanzi bangempela, iyinkomba enzima	Izilinganiso ezibaluleke kakhulu zeshubhu lensimbi ububanzi bangaphandle (OD) nobukhulu bodonga (WT). Lawa mapharamitha avezwa ngamayintshi noma amamilimitha futhi aveza inani langempela lobukhulu besigaba esingenalutho.
Ukuqina Kwezindonga	Ubukhulu bepayipi lensimbi buqokwe ngenani elithi "Sheduli" (okuvamile yi-Sch. 40, Sch. STD., Sch. XS, Sch. XXS). Amapayipi amabili e-NPS ahlukene kanye neshejuli efanayo anobukhulu obuhlukile bodonga ngamayintshi noma amamilimitha.	Ugqinsi lwezindonga zeshubhu lensimbi zivezwa ngamasentimitha noma amamilimitha. Ukuze uthole amashubhu, ubukhulu bodonga bulinganiswa futhi nge-nomenclature ye-gage.
Izinhlobo zamapayipi namashubhu (Amamo)	Umjikelezo kuphela	Umjikelezo, unxande, isikwele, okusaqanda
Ibanga lokukhiqiza	Okubanzi (kufika ku-80 amayintshi nangaphezulu)	Ibanga elincane lamashubhu (kufika kumayintshi angu-5), elikhudlwana lamashubhu ensimbi okusetshenziswa ngomshini
Ukubekezelela (ukuqonda, ubukhulu, ukujikeleza, njll) kanye namandla ePipe vs. Tube	Ukubekezelelana kusethiwe, kodwa kunalokho okuxekethile. Amandla akuyona into ekhathaza kakhulu.	Amashubhu ensimbi akhiqizwa ukubekezelelana okuqinile kakhulu. Ama-tubular ahlolwa ikhwalithi enobukhulu obumbalwa, njengokuqondile, ukuzungeza, ukushuba kodonga, indawo engaphezulu, ngesikhathi senqubo yokukhiqiza. Amandla emishini ayinkinga enkulu yamashubhu.
Inqubo Yokukhiqiza	Amapayipi ngokuvamile enziwa ukuthi abe nesitoko anezinqubo ezizenzakalelayo nezisebenza kahle kakhulu, okungukuthi izigayo zamapayipi zikhiqiza ngokuqhubekayo kanye nesitoko sabasabalalisi besiphakeli emhlabeni jikelele.	Ukukhiqiza amashubhu kuthatha isikhathi eside futhi kuyakhandla
Isikhathi sokuthumela	Kungaba mfushane	Ngokuvamile isikhathi eside
Intengo yemakethe	Intengo ephansi ngokuqhathaniswa ngethani ngalinye kunamashubhu ensimbi	Iphakeme ngenxa yokukhiqiza okuphansi kwezigayo ngehora, futhi ngenxa yezidingo eziqinile mayelana nokubekezelelana nokuhlolwa
Izinto zokwakha	Uhlu olubanzi lwezinto ezitholakalayo	Amashubhu atholakala nge-carbon steel, i-alloy ephansi, insimbi engagqwali, nama-nickel-alloys; amashubhu ensimbi okusebenza ngomshini ngokuvamile ayi-carbon steel
Qeda Ukuxhumana	Okuvame kakhulu kukhona iziphetho ezigobile, ezicacile nezikrufu	Iziphetho ezinomucu nezigobile ziyatholakala ukuze kuxhunywe ngokushesha kusayithi
