Iyini Ipayipi Elingenamthungo Eligoqekile Elishisayo?

Amapayipi ayisisekelo ezimbonini ezifana nowoyela negesi, ezokwakha, ezimoto, kanye nokukhiqiza imishini. Phakathi kwezinhlobo ezahlukene,ipayipi elingenamthungo eligoqiwe elishisayoIvelele ngamandla ayo, ukufana, kanye nekhono lokubekezelela ukucindezela okuphezulu kanye nokushisa. Ngokungafani namapayipi ahlanganisiwe, amapayipi angenamthungo awanawo umthungo wokushisela, okwenza afaneleke kakhulu ekusetshenzisweni okubalulekile. Kulesi sihloko, sizohlola ukuthi iyini ipayipi elingenamthungo eligoqiwe elishisayo, ukuthi lenziwa kanjani, izinzuzo zalo, kanye nezinhlelo zalo ezivamile kuzo zonke izimboni.

1. Incazelo: Iyini Ipayipi Elingenamthungo Eligoqekile Elishisayo?

A ipayipi elingenamthungo eligoqiwe elishisayouhlobo lwepayipi lensimbi elenziwengaphandle kokushiselafuthi yakhiwe nge-inqubo yokugoqa eshisayoIgama elithi “elingenamthungo” libonisa ukuthi ipayipi alinawo umgogodla noma umthungo ubude balo, okuthuthukisa amandla nobuqotho balo.

Ukugoqa okushisayo kubhekisela ekwakheni ipayipi ku-amazinga okushisa aphezulu, ngokuvamile ngaphezu kuka-1000°C, okuvumela insimbi ukuthi ibunjwe futhi icutshungulwe kalula. Le ndlela iphumela epayipini eliqinile, elilinganayo elifanele ukusetshenziswa okubanzi okudinga amandla.

2. Yenziwa Kanjani Ipayipi Elingenamthungo Eligoqekile Elishisayo?

Ukukhiqizwa kwepayipi eligoqiwe elishisayo elingenamthungo kuhilela izinyathelo eziningana ezibalulekile:

a) Ukulungiselela I-Billet

• I-billet yensimbi eqinile esilindayo iyanqunywa ibe nobude obufunayo.

• I-billet ishiswa esithandweni somlilo kuze kufike ekushiseni okuphezulu ukuze ikwazi ukuguguleka.

b) Ukubhoboza

• I-billet efudumele idlula emshinini wokubhoboza ukuze kudalwe isikhungo esingenalutho.

• Isibhobozi esijikelezayo kanye nama-roller kusetshenziselwa ukwakha isimo esiyisisekelo se-tubular.

c) Ukwelulwa

• I-billet ebhoboziwe (manje eyipayipi elingenalutho) idluliswa ezigayweni zokunwebeka njenge-mandrel mills noma i-plug mills.

• Lezi zigayo zelula ithubhu futhi zithuthukise ubukhulu nobubanzi bodonga.

d) Ukugingqika Okushisayo

• Ithubhu liphinde lakhiwe futhi lalinganiswa ngokusebenzisa imishini yokugoqa eshisayo.

• Lokhu kuqinisekisa ukufana nokunemba kobukhulu.

e) Ukupholisa Nokuqondisa

• Ipayipi lipholiswa kumshini wokuthutha noma emoyeni.

• Bese iqondiswa bese inqunywa ibe ubude obufiselekayo.

f) Ukuhlolwa Nokuhlolwa

• Amapayipi adlula ezivivinyweni ezahlukene ezingabhubhisi futhi ezibhubhisayo (isb., i-ultrasonic, i-hydrostatic).

• Ukumaka nokupakisha kwenziwa ngokwezindinganiso zemboni.

i-sakysteelinikeza amapayipi ashisayo angenamthungo ngamamaki nobukhulu obuhlukahlukene, ahlolwe ngokugcwele futhi aqinisekiswe ukuqinisekisa ikhwalithi.

3. Izici Eziyinhloko Zepayipi Elingenamthungo Eligoqiwe Elishisayo

• Isakhiwo Esingenamthungo: Ukungabikho komthungo ohlanganisiwe kusho ukumelana okungcono kwengcindezi kanye nokuqina kwesakhiwo.

• Ukumelana Nokushisa Okuphezulu: Ingamelana nokushisa okuphezulu ngaphandle kokuguquka noma ukwehluleka.

• Ukubekezelela Ukucindezeleka: Ukusebenza okuhle kakhulu ngaphansi kwengcindezi ephezulu yangaphakathi noma yangaphandle.

• Ubukhulu Bodonga Obufanayo: Ukugoqa okushisayo kuqinisekisa ukulawula ukujiya okungcono.

• Ukuqedwa Okuhle Komphezulu: Nakuba kungebushelelezi njengamapayipi adonswa kubanda, amapayipi aguqiwe ashisayo anokuphela okwamukelekayo ukusetshenziswa ezimbonini.

4. Izinto kanye namazinga

Amapayipi ashisayo angenamthungo atholakala ngezinto ezahlukahlukene kuye ngokuthi isicelo sisebenza kanjani:

Izinto Ezivamile:

• Insimbi yekhabhoni (ASTM A106, ASTM A53)

• Insimbi ye-alloy (ASTM A335)

• Insimbi engagqwali (ASTM A312)

• Insimbi enezinga lokushisa eliphansi (ASTM A333)

Izindinganiso Ezivamile:

• I-ASTM

• I-EN/DIN

• I-API 5L / I-API 5CT

• I-JIS

• I-GB/T

i-sakysteelihlinzeka ngokuhambisana ngokugcwele nezimfuneko zomhlaba wonke ukuze kuhlangatshezwane nezidingo zezimakethe zomhlaba wonke.

5. Ukusetshenziswa kwePipe Engenamthungo Eshisayo Egoqwe Kakhulu

Amapayipi ashisayo angenamthungo asetshenziswa emikhakheni eminingi ngenxa yokuthembeka kwawo nokusebenza kwawo.

a) Imboni Kawoyela Negesi

• Ukuthutha uwoyela ongahluziwe kanye negesi yemvelo

• Ipayipi elingaphansi kwembobo kanye nebhokisi

• Amapayipi okuhlanza

b) Ukukhiqizwa Kwamandla

• Amapayipi ebhoyila

• Amashubhu okushintshanisa ukushisa

• Izingxenye ze-Superheater

c) Ubunjiniyela Bemishini

• Izingxenye zomshini nezingxenye

• Amasilinda e-hydraulic

• Ama-shaft nama-roller egiya

d) Ukwakhiwa kanye Nengqalasizinda

• Izisekelo nezinhlaka zesakhiwo

• Amapayipi okufaka inqwaba

• Amabhuloho nezakhiwo zensimbi

e) Imboni Yezimoto

• Ama-axle kanye nezingxenye zokumiswa

• Imiphini yokudlulisa

• Izingxenye zokuqondisa

i-sakysteelinikeza amapayipi ashisayo agoqwe kahle aklanyelwe lezi zinhlelo zokusebenza, okuqinisekisa ukuqina kanye nemininingwane eqondile.

6. Izinzuzo Zepayipi Elingenamthungo Eligoqiwe Elishisayo

Kuqine Futhi Kuphephile

• Ukungabikho kwamalunga ahlanganisiwe kusho ukuthi kuncane ubuthakathaka kanye nokuqina okungcono.

Kuhle kakhulu ekusetshenzisweni komfutho ophezulu

• Kuhle kakhulu ekuthuthweni koketshezi kanye negesi ngaphansi komfutho ophezulu.

Ububanzi Bosayizi Obubanzi

• Itholakala ngobukhulu obukhulu kanye nobukhulu bodonga okunzima ukubufinyelela ngamapayipi ahlanganisiwe.

Impilo Yenkonzo Ende

• Ukumelana kangcono nokukhathala, ukuqhekeka, kanye nokugqwala.

Isebenziseka Kakhulu

• Ifanele kokubili ukusetshenziswa kwesakhiwo kanye nokwemishini.
