Ubude obujwayelekile bokulethwa kwecarbon steel pipe, okwaziwa nangokuthi ubude bezidingo zomsebenzisi noma ubude benkontileka, kukhona izinhlinzeko ezine kumazinga akhona:
A, Ubude obujwayelekile(okwaziwa nangokuthi ubude obungahleliwe): noma yibuphi ubude obungaphakathi kobude bezinga elidingekayo futhi azikho izidingo zobude obumisiwe ngokuvamile ezibizwa ngokuthi ubude obuvamile.
B, Ubude bokusika: ubude bokusika kufanele bube phakathi kwebanga lobude obujwayelekile, okudingeka kunkontileka ubukhulu obumisiwe.Kodwa ukusebenza kwangempela kuyasikwa futhi akunakwenzeka, ngakho-ke indinganiso icacisa ubude bobude bokuchezuka okuhle okuvunyelwe.Ukukhiqiza ukuncipha ubude kunobude bobude bepayipi lepayipi ngokuvamile kuwumkhawulo omkhulu wesivuno, abakhiqizi abahlongozwayo bakhuphule imali yokugibela kunengqondo.Amabhizinisi we-Markups awafani, ngokuvamile asekelwe ekwenyukeni kwenani eliyisisekelo cishe ngo-10%.
C, Ubude obuphindwe kabili: ngokuya ngemfuneko yokuhleleka, ubude iyinani eliphelele eliphindwe kabili futhi kubhekiselwa kubo njengobude obuphindwe kabili.ubude obuphindwe kabili kufanele bube phakathi kwebanga lobude obujwayelekile, inkontileka kufanele icacise ubude obuphindwe kabili kanye nokwakheka kwengqikithi yobude obuphindaphindwayo.Empeleni, ubude obuphelele kufanele busekelwe ekuchezukeni okuvumelekile okuvunyelwe ngo-20mm, kanye nobude obuphindwe kabili bomkhawulo ngamunye wokusikela kufanele kuhlale.Uma ukuchezuka okujwayelekile kungenabo ubude obuphindwe kabili kanye nezimfuneko zokusika imajini , kufanele kuxoxiswene nazo zombili izinhlangothi futhi zicaciswe kunkontileka.Ubude besilinganiso sezikhathi ezinde bulingana nobude bokukhiqiza buzoletha ukuncipha okukhulu kwesivuno, ngakho-ke abakhiqizi abahlongozwayo bakhuphuka banengqondo, futhi izinga lakho lokukhuphuka ngobude bezinga lokukhuphuka lilingana kakhulu nobude.
D, Ubude bobubanzi: ubude bebanga bungaphakathi kwebanga lobude obuvamile, lapho umsebenzisi ecela ububanzi obugxilile lapho ubude besikhathi, budinga ukucaciswa khona kunkontileka.
