Amapayipi ensimbi ayisikwele noma angama-rectangular avame ukusetshenziswa kumaphrojekthi wokwakha futhi ngokuvamile asetshenziselwa izisekelo zokufakwa kwamapayipi, ukufinyelela kwendawo yesikhashana, amaphrojekthi kagesi, i-keel yokuhlobisa, njll.
Lapho ubukhulu bepayipi lensimbi elingunxande likhulu ngokwanele, siyakwazi ukungawunaki umphumela wamakhona ayindilinga esisindweni, isibonelo, ipayipi elingunxande emgudwini, isisindo esilahleke amakhona amane ayindilinga asinakwa esigabeni esikhulu kakhulu. .
Kodwa-ke, ipayipi yensimbi encane ye-cross-sectional square, ipayipi yensimbi engunxande, kuyadingeka ukucabangela i-radius yamakhona ayindilinga R lapho ubala isisindo. Ngokuvamile, ukuhlolwa akunaki umehluko wesisindo mayelana ne-5% kuya ku-10%, ehlobene nezindleko zabakhiqizi bezinto ezincane. Ngakho-ke singabala kanjani isisindo seyunithi imitha ngayinye yomugqa wepayipi lensimbi elingunxande elinekona elingu-R?
Ukuze ubale isisindo ngobude beyunithi ngayinye yephrofayili, ngokuvamile kufanele sithole indawo ephambanayo bese siyiphindaphinda ngokuminyana kwezinto ezihambisanayo, futhi singathola isisindo seyunithi yayo.
Kushubhu elingunxande eliboniswe ngezansi, singathola kalula indawo ephambanayo A = H*B-(H-2t)*(B-2t) yaso sonke isigaba uma singacabangi umthelela we-engeli engu-R.
Uma irediyasi yekhona elingaphandle sekwaziwa ukuthi ngu-R, simane sengeze indawo yebhulokhi eluhlaza okwesibhakabhaka bese sikhipha indawo yebhulokhi ebomvu (njengoba kuboniswe esithombeni esingezansi) ukuze sithole indawo yangempela yesigaba. Futhi, kumashubhu amaningi angama-rectangular, amakhona angaphakathi nangaphandle ayisikhungo esiyindilinga esifanayo, ngakho-ke i-radius yekhona elingaphakathi r = Rt. Ngemva kokuthola la maphuzu, singathola kalula ifomula yendawo.
Ngaphezu kwalokho, ku-specification "GBT 3094-2012 ipayipi yensimbi emise okubandayo", inikeze ifomula ethile yokubala isisindo esisodwa, isimiso sayo sokubala futhi ngishilo ngenhla futhi siyavumelana, ungabhekisela eshadini elilandelayo.
Bheka ifomula, singathola ukuthi inani lika-R ekucacisweni linqunywa ukushuba kodonga lwepayipi lensimbi, ngakho-ke uma ungazi inani elithile lika-R lokuthi yimalini, ungathatha futhi inani ngokuya ngokucaciswa. , leyo -
R=1.5 izikhathi zokujiya kodonga lapho ukujiya kodonga kungu-≤6mm. Lapho ukujiya kodonga > 6mm, R = izikhathi ezi-2 ukujiya kodonga
Empeleni, singakwazi futhi ukubala isisindo seyunithi yamashubhu angunxande anamakhona ayindilinga sisebenzisa amathuluzi esinawo.

U-Yuantai Delun uhlanganyela kakhulu ku-"ipayipi lensimbi yesikwele","ipayipi lensimbi elingunxande"futhi"ipayipi lensimbi eliyindilinga", singabonisana futhi sihlele ngokubhekisela esimweni sethu. Ekugcineni, ngokuchofoza inkinobho yefomu ekhoneni elingezansi kwesokudla, singakwazi ukufunda amapharamitha aqondile, okuhlanganisa indawo engaphezulu kanye nezakhiwo zemishini zephrofayela, ezinemininingwane eminingi.
