I-curvature radius yeindololwane yensimbi engagqwaliizolawulwa. Isibonelo, uma ubude berediyasi bungu-1.5D, irediyasi yokugoba kufanele ibe ngaphakathi kokubekezelelana okudingekayo.

Njengoba iningi lalezi zinto zokufakwa kwamapayipi zisetshenziselwa ukushisela, ukuze kuthuthukiswe ikhwalithi ye-welding, iziphetho ziguqulwa zibe ama-grooves, nge-angle ethile kanye nomkhawulo othile. Le mfuneko nayo iqinile. Kunamalungiselelo ngokuqina konqenqema, i-engeli kanye nobubanzi bokuchezuka, futhi kunezilinganiso eziningi zejiyomethri kunokufakwa kwamapayipi. Izinga eliphezulu kanye nemishini yendololwane ngokuyisisekelo iyafana neyamapayipi. Ukuze kube lula ukushisela, izinto zensimbi zizofana nepayipi elixhunyiwe.

1. Njengoba ukufakwa okuningi kwamapayipi kusetshenziselwa ukushisela, ukuze kuthuthukiswe ikhwalithi ye-welding, iziphetho ziguqulwa zibe ama-grooves, nge-angle ethile kanye nomkhawulo othile. Le mfuneko nayo iqinile. Kunemithetho yokuqina konqenqema, i-engeli kanye nobubanzi bokuchezuka. Izinga eliphezulu kanye nezakhiwo zemishini ngokuyisisekelo ziyafana nalezo zamapayipi. Ukuze kube lula ukushisela, izinga lensimbi lokufakwa kwamapayipi namapayipi axhunyiwe kuyafana.

1. Okusho ukuthi, konke ukufakwa kwamapayipi kuzobhekana nokuphathwa kwendawo, futhi isikali se-iron oxide endaweni yangaphakathi nengaphandle sizofafazwa ngokuchama, bese simbozwa ngopende ovimbela ukugqwala. Lokhu okwezidingo zokuthekelisa. Ngaphezu kwalokho, e-China, futhi ukwenza lula ezokuthutha nokuvimbela ukugqwala kanye ne-oxidation.

1. Okusho ukuthi, izidingo zokupakisha. Ukufakwa kwamapayipi amancane, njengokuthekelisa, amabhokisi okhuni adinga ukwenziwa, cishe i-cubic meter eyi-1. Kubekwe ukuthi inani lezindololwane emabhokisini anjalo alikwazi ukudlula ithani elingu-1. Izinga livumela amasudi, okungukuthi, amasethi amakhulu namasethi amancane, kodwa isisindo esiphelele asikwazi ukudlula ithani elingu-1. Ezingxenyeni ezinkulu y, iphakheji elilodwa liyadingeka.
