Liyini Ipayipi Elingenamthungo Eligoqiwe Elishisayo?

Amapayipi abalulekile ezimbonini ezifana nowoyela negesi, ezokwakha, ezezimoto, nezokukhiqiza imishini. Phakathi kwezinhlobo ezahlukene,ipayipi elingenamthungo elishisayo eligoqiweigqama ngamandla ayo, ukufana, kanye nekhono layo lokumelana nomfutho ophezulu kanye nezinga lokushisa. Ngokungafani namapayipi ashiselwe, amapayipi angenamthungo awanawo umthungo we-weld, okuwenza alungele ukusetshenziswa okubucayi. Kulesi sihloko, sizohlola ukuthi liyini ipayipi eligoqiwe elingenamthungo elishisayo, likhiqizwa kanjani, izinzuzo zalo, kanye nokusetshenziswa kwalo okuvamile kuzo zonke izimboni.

1. Incazelo: Iyini Ipayipi Elingenamthungo Elishisayo Eligoqiwe?

A ipayipi elingenamthungo elishisayo eligoqiweluhlobo lwepayipi lensimbi elakhiwengaphandle kokushiselafuthi kwakhiwa ngokusebenzisa ahot rolling inqubo. Igama elithi "i-seamless" libonisa ukuthi ipayipi ayinayo inhlanganisela noma i-seam ngobude bayo, okuthuthukisa amandla nobuqotho bayo.

Ukuginqika okushisayo kubhekisela ekwenzeni ipayipi kuamazinga okushisa aphezulu, ngokuvamile ngaphezu kuka-1000 ° C, okuvumela insimbi ukuba ibunjwe kalula futhi icutshungulwe. Le ndlela ibangela ipayipi eliqinile, elilinganayo elifanele uhla olubanzi lwezicelo ezidingayo.

2. Lenziwa Kanjani Ipayipi Elingenamthungo Eligoqiwe Elishisayo?

Ukwenziwa kwepayipi elingenamthungo eligoqwe elishisayo kuhilela izinyathelo ezimbalwa ezibalulekile:

a) Ukulungiselela i-Billet

• I-billet yensimbi eyi-cylindrical eqinile isikwa ubude obufunayo.

• I-billet ishiswa esithandweni ukuze ibe nezinga lokushisa eliphezulu ukuze ikwazi ukuthambile.

b) Ukubhoboza

• I-billet eshisayo idlula emshinini wokubhoboza ukuze kwakhiwe isikhungo esingenalutho.

• Umbhobozi ojikelezayo namarola asetshenziselwa ukwakha umumo we-tubular oyisisekelo.

c) Ukwelula

• I-billet ebhoboziwe (manje eyishubhu elingenalutho) idluliswa ezigayweni ezinwebekayo njengezigayo ze-mandrel noma izigayo zamapulaki.

• Lezi zigayo zelula ishubhu futhi zicwengisise ukujiya kodonga nobubanzi.

d) Ukuginqika Okushisayo

• Ishubhu liphinde libe nokwakheka futhi lilinganiselwe ngokusebenzisa izigayo ezishisayo ezigoqayo.

• Lokhu kuqinisekisa ukufana nokunemba kobukhulu.

e) Ukupholisa kanye nokuqondisa

• Ipayipi lipholile ku-conveyor noma emoyeni.

• Bese iqondiswa futhi isikwe ngobude obufunayo.

f) Ukuhlolwa nokuhlolwa

• Amapayipi abhekana nokuhlolwa okuhlukahlukene okungabhubhisi nokulimazayo (isb, i-ultrasonic, i-hydrostatic).

• Ukumaka nokupakishwa kwenziwa ngokwezindinganiso zomkhakha.

sakysteelinikeza amapayipi ashisayo agingqelwe angenamthungo ngamabanga nosayizi abahlukahlukene, ahlolwe ngokugcwele futhi agunyazwe ukuqinisekiswa kwekhwalithi.

3. Izici Eziyinhloko Zepayipi Elingenamthungo Eligoqiwe Elishisayo

• Isakhiwo Esingenamthungo: Akukho mthungo oshiselwe kusho ukumelana nokucindezela okungcono nobuqotho besakhiwo.

• Ukumelana Nokushisa Okuphezulu: Ingakwazi ukumelana nokushisa okuphezulu ngaphandle kokuguqulwa noma ukwehluleka.

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

• Ubugqinsi Bodonga obufanayo: Ukugoqa okushisayo kuqinisekisa ukulawula ukushuba okungcono.

• I-Surface Enhle Qeda: Nakuba engebushelelezi njengamapayipi adonswa abandayo, amapayipi ashisayo asongwe anesiphetho esamukelekayo ukuze asetshenziswe ezimbonini.

4. Izinto kanye namazinga

Amapayipi angenamthungo agingqelwe ashisayo ayatholakala ngezinto ezahlukahlukene ngokuya ngesicelo:

Izinto Ezivamile:

• I-Carbon steel (ASTM A106, ASTM A53)

• Insimbi ye-alloy (ASTM A335)

• Insimbi engagqwali (ASTM A312)

• Insimbi enezinga lokushisa eliphansi (ASTM A333)

Amazinga Ajwayelekile:

• I-ASTM

• EN/DIN

• I-API 5L / API 5CT

• I-JIS

• I-GB/T

sakysteelihlinzeka ngokuhambisana ngokugcwele nezicaciso zamazwe ngamazwe ukuhlangabezana nezidingo zezimakethe zomhlaba.

5. Izicelo ze-Hot Rolled Seamless Pipe

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

a) Imboni kawoyela negesi

• Ukuthutha uwoyela ongahluziwe negesi yemvelo

• I-Downhole tubing kanye ne-casing

• Amapayipi okuhluza

b) Ukukhiqiza Amandla

• Amashubhu e-boiler
