Amapayipi ensimbi ayisikwele noma angunxande avame ukusetshenziswa kumaphrojekthi okwakha futhi ngokuvamile asetshenziselwa izisekelo zokufakwa kwamapayipi, ukufinyelela indawo yesikhashana, amaphrojekthi kagesi, i-keel yokuhlobisa, njll.
Uma usayizi wepayipi lensimbi elingunxande likhulu ngokwanele, siyakwazi ukungawunaki umphumela wamakhona ayindilinga esisindweni, isibonelo, ipayipi elingunxande emhubheni, isisindo esilahleka ngamakhona amane ayindilinga asinamsebenzi engxenyeni enkulu kakhulu.
Kodwa-ke, ngepayipi elincane lensimbi eliyisikwele elihlanganisa izingxenye ezimbili, ipayipi lensimbi elingunxande, kubalulekile ukucabangela irediyasi yamakhona ayindilinga u-R lapho kubalwa isisindo. Ngokuvamile, ukuhlolwa akubheki umehluko wesisindo cishe ku-5% kuya ku-10%, okuhlobene nezindleko zabakhiqizi bezinto ezincane. Ngakho-ke ungabala kanjani isisindo seyunithi ngemitha eqondile yepayipi lensimbi elingunxande elihlanganisa izingxenye ezimbili ngekona lika-R?
Ukuze sibale isisindo ngeyunithi ngayinye ubude bephrofayili, ngokuvamile kufanele sithole indawo enqamulelayo bese siyiphindaphinda ngobuningi bezinto ezibonakalayo obuhambisanayo, bese sithola isisindo sayo seyunithi.
Ngethubhu elingunxande eliboniswe ngezansi, singathola kalula indawo enqamula ingxenye A = H*B-(H-2t)*(B-2t) yengxenye yonke uma singacabangi ngomphumela we-R-angle.
Uma irediyasi yekona yangaphandle seyaziwa ukuthi ingu-R, simane sengeze indawo yebhulokhi eluhlaza okwesibhakabhaka bese sisusa indawo yebhulokhi elibomvu (njengoba kuboniswe esithombeni esingezansi) ukuze sithole indawo yangempela yesigaba. Futhi, kumashubhu amaningi angunxande, amakhona angaphakathi nangaphandle ayisikhungo esifanayo sendilinga, ngakho irediyasi yekona yangaphakathi u-r = Rt. Ngemva kokuthola la maphuzu, singathola kalula ifomula yendawo.
Ngaphezu kwalokho, esichazini esithi "ipayipi lensimbi elinomumo odonswayo obandayo i-GBT 3094-2012", linikeze ifomula ethile yokubala isisindo esisodwa, isimiso sayo sokubala futhi ngishilo ngenhla naso siyavumelana, ungabheka ishadi elilandelayo.
Qaphela ifomula, singathola ukuthi inani lika-R ku-specification linqunywa ubukhulu bodonga lwepayipi lensimbi, ngakho-ke uma ungazi inani elithile lika-R lokuthi lingakanani, ungathatha nenani ngokwe-specification, okungukuthi -
U-R=1.5 izikhathi ubukhulu bodonga uma ubukhulu bodonga bungu-≤6mm. Uma ubukhulu bodonga bungu->6mm, u-R=2 izikhathi ubukhulu bodonga
Empeleni, singabala futhi isisindo seyunithi yamashubhu angunxande anamakhona ayindilinga ngqo sisebenzisa amathuluzi esinawo.
