Nakuba usayizi uyisici esibalulekile lapho ukhetha ama-flange, izindololwane, nezinye izingxenye zenqubo yakho yokufaka amapayipi, iziphetho zamapayipi ziwukucatshangelwa okubalulekile ukuze kuqinisekiswe ukulingana okufanele, ukuvala okuqinile, nokusebenza okuphelele.

Kulo mhlahlandlela, sizobheka ukucushwa okuhlukahlukene kokuphela kwepayipi okutholakalayo, izimo avame ukusetshenziswa kuzo, nezici okufanele uzicabangele lapho ukhetha ukuphela kwepayipi elithile.

IPHAPHA ELIJWAYELEKILE LIYAPHELA

Uhlobo lokuphela kwepayipi olukhethiwe luzonquma ukuthi luxhuma kanjani kwezinye izingxenye nokuthi yiziphi izinhlelo zokusebenza nezingxenye ipayipi ezilungele kangcono.

Iziphetho zamapayipi ngokuvamile ziwela kwesinye sezigaba ezine:

• I-Plain Ends (PE)
• I-Treaded Ends (TE)
• I-Bevelled Ends (BW)
• Amajoyinti Emishini Akhulisiwe noma Ama-Grooved End

Ipayipi elilodwa lingase libe nezinhlobo eziningi zokugcina.Lokhu kuvame ukuqokwa encazelweni yepayipi noma ilebula.

Isibonelo, ipayipi le-3/4-intshi le-SMLS Shejuli 80s A/SA312-TP316L TOE linemicu kwelinye icala (TOE) futhi alicacile ngakolunye.

Ngokuphambene, ipayipi le-3/4-intshi le-SMLS Schedule 80s A/SA312-TP316L TBE linemicu kuzo zombili iziphetho (TBE).

UKUSETSHENZISWA KOKUGCINA OKUPHELELE (PE) KANYE NOKUCABANGA NGAKHO

Isici samapayipi e-PE siphetha ngokujwayelekile ukusikwa nge-engeli engu-90-degree ukuya epayipini eligijima ukuze libe isicaba, ngisho nokunqanyulwa.

Ezimweni eziningi, amapayipi angenalutho asetshenziswa ngokuhambisana nama-slip-on flanges kanye ne-socket weld fittings nama-flanges.

Zombili izitayela zidinga ukushiselwa kwe-fillet kunoma iyiphi izinhlangothi noma zombili ze-fitting noma i-flange kanye nesisekelo sokulinganisa noma i-flange.

Lapho kufanele khona, indawo engenalutho izobekwa ngokujwayelekile ⅛” ukusuka lapho ipayipi lihlala khona ukuze kuvunyelwe ukunwetshwa okushisayo ngesikhathi sokushisela.

Lokhu kubenza balungele izinhlelo zamapayipi amancane obubanzi.

UKUSETSHENZISWA KOKUPHELA OKUNOBUCHUPHE (TE) KANYE NEZINKABANGO

Ngokuvamile asetshenziselwa amapayipi anosayizi ojwayelekile wamayintshi amathathu noma amancane, amapayipi e-TE avumela uphawu oluhle kakhulu.

Amapayipi amaningi asebenzisa i-National Pipe Thread (NPT) ejwayelekile echaza izintambo ezicijile ezisetshenziswa epayipini eline-taper evame kakhulu ekala 3/4-intshi ngonyawo.

Le taper ivumela imicu ukuthi idonse iqine futhi idale uphawu olusebenza kangcono.

Nokho, ukuxhuma imicu epayipini le-TE ngendlela efanele kubalulekile ukuze ugweme ukulimaza amapayipi, okokufakwayo, noma ama-flange.

Ukuhlangana okungafanele noma ukuhlakazwa kungaholela ekuqhumeni noma ekubanjweni.

Uma ingasetshenziswanga, umonakalo emiculweni noma epayipini ingase inciphise ukumelana nokugqwala kanye nezakhiwo ezihlanzekile - izizathu ezimbili ezithandwayo zokukhetha ipayipi lensimbi engagqwali.

Ngenhlanhla, ukugwema lezi zinto ezikhathazayo ngokuvamile kulula njengokulungisa imicu ngaphambi kokuhlanganisa.

Sincoma futhi sithengise itheyiphu yokuvala intambo yensimbi engenasici ye-Unasco.

Ifakwe nge-nickel powder, itheyiphu igcina ingaphezulu lentambo yesilisa neyesifazane igcina ngokuhlukana ngenkathi igcoba ukuxhumana ukuze kube lula ukuhlanganisa nokuqaqa.

I-BEVELLED END (BW) UKUSETYENZISWA KANYE NOKUCABANGA

Isetshenziswa ne-buttwelding, ukufakwa kwepayipi le-BW kuvame ukufaka i-bevel engu-37.5-degree.

Lawa ma-bevel avame ukusetshenziswa ngabakhi bezandla noma ngezinqubo ezizenzakalelayo ukuze kuqinisekiswe ukungaguquguquki.

Lokhu kuvumela ukuhambisana kahle nokufakwa kwamapayipi e-BW nama-flange kanye nokushisela okulula.

UKUSETSHENZISWA KANYE NOKUCABANGA NGAKHO

Amajoyinti ayizinsimbi agxilile noma amapayipi okugcina asele asebenzisa umsele owakhiwe noma owenziwe ngomshini ekugcineni kwepayipi ukuze kuhlaliswe i-gasket.

Izindlu ezizungeze i-gasket zibe seziqiniswa ukuze kuvikelwe ukuxhuma futhi kuqinisekiswe ukuvala nokusebenza kahle.

Idizayini ivumela ukuqaqa lula ngengozi encishisiwe yokulimaza izingxenye zamapayipi.

Ipayipi ELIJWAYELEKILE LIQEDA IZIFUSHANE NAMAZINGA

Izixhumanisi zamapayipi ngokuvamile ezisetshenziselwa izingono zamapayipi - ngokuvamile zichazwa kusetshenziswa izifinyezo.

Ezimweni eziningi, uhlamvu lokuqala lubonisa uhlobo lwesiphetho esisetshenzisiwe kuyilapho izinhlamvu ezilandelayo zikwazisa ukuthi yiziphi iziphetho eziqediwe.

Izifinyezo ezijwayelekile zifaka:

• YIBA:Bevel End
• BBE:I-Bevel Yomibili Iphela
• BLE:Bevel Ukuphela Okukhulu
• I-BOE:Bevel One End
• I-BSE:I-Bevel Encane End
• BW:Buttweld End
• I-PE:I-Plain End
• I-PBE:I-Plain Yomibili Iziphetho
• I-POE:I-Plain One End
• TE:Ukuphela Kwentambo
• I-TBE:Intambo Yomibili Iphela
• TLE:Intambo Enkulu Isiphetho
