Ngokubanzi, iimibhobho yentsimbiimibhobho okanye iinqanawa zoxinzelelo zisebenzisa i-PIPE, kwaye izixhobo zombhobho zibizwa ngokuba yi-PIPEFITTING.
Umbhobho (wenziwe ngokwemigaqo yemibhobho esemgangathweni) PIPE
Imibhobho (eminye imibhobho engenziwanga ngokwemigaqo yomgangatho wemibhobho) TUBE
I-TUBE ingaba nayiphi na imilo ye-cross-sectional, i-PIPE kufuneka ibe yingqukuva.
Umbhobho kunye ityhubhu okwangoku ziguqulelwa njengemibhobho, kodwa iPIPE iboniswa ngokubanzi ngedayamitha yangaphakathi kunye nenani lokutyeba kodonga (SCH), kubandakanywa imibhobho edityanisiweyo kunye nemibhobho engenamthungo.Iityhubhu, ezibandakanya iityhubhu ezidityanisiweyo kunye neetyhubhu ezingenamthungo, zisetyenziselwa ukuhambisa ubushushu, njengetyhubhu zokutshintsha ubushushu kunye neetyhubhu zecondenser.Kwisiqinisekiso senkqubo ye-welding, akukho mahluko phakathi kwemisebenzi yeetyhubhu ezisekelwe kwisiqinisekiso senkqubo, ngoko umbhobho kunye ne-tube ingasetyenziswa.Ngokubanzi, kumqulu wesibini we-ASME, iPipe inokuguqulelwa njengetyhubhu yokuhambisa ubushushu njengetyhubhu yokuhambisa ulwelo.
Imigangatho yezinto zemibhobho yensimbi yase-United States kunye neJapan yahlula ngokucacileyo umbhobho wensimbi kwiindidi ezimbini: Umbhobho kunye neTube (ifomula yokubala yobunzima bodonga kumgangatho uhlukile).
Umbhobho ubhekisa kumbhobho onomngxuma onecandelo lesetyhula elisetyenziselwa ukuthutha ulwelo.Inkcazo yayo ibonakaliswe nge-diameter ye-nominal kunye nochungechunge lwamadonga (okanye ubukhulu bodonga).Kwimibhobho enomlinganiselo ofanayo wegama, ubukhulu bodonga bunokwahluka, kodwa ububanzi bangaphandle bufana.Umbhobho ngumbhobho oyintloko wemibhobho yezoshishino.Umbhobho ikakhulu usekelwe kumsebenzi wokuthutha i-pressure medium ukusuka kwindawo enye ukuya kwenye, kwaye ayigxininisi kumsebenzi wokutshintsha ubushushu.Umzekelo, imibhobho ephambili yomphunga, imibhobho yokunyuka nokuwa, njl njl okanye eminye imibhobho edityaniswe neendlela ezintathu, ingqiniba kunye nevalve yimibhobho yePipe.
Ityhubhu ligama eliqhelekileyo letyhubhu engenanto, enokuthi ibe setyhula okanye ezinye iimilo.Kwityhubhu ejikelezayo, inkcazo inqunywe ngamabini obubanzi obungaphandle, ububanzi bangaphakathi kunye nobukhulu bodonga.Iityhubhu iqhele ukusetyenziswa kwimibhobho edayamitha emincinci (i-intshi ezi-5 okanye ngaphantsi) njengemibhobho yesixhobo, imibhobho yokukhangela ubushushu, ihydraulic okanye imibhobho yomoya, njl.njl. kwiinkqubo zemibhobho.Iityhubhu zetyhubhu zijolise ikakhulu ekuqhubeni ubushushu bangaphakathi nangaphandle kunye neenjongo zokutshintshiselana kobushushu, ezinje ngeetyhubhu zokufudumeza, iityhubhu zokufudumeza, iityhubhu zokonga igesi kunye neetyhubhu zodonga ezipholiswe ngamanzi.Ngokuqhelekileyo, ixabiso leyunithi yeTube liphezulu kunelo lePipe.
