Yintoni uMbhobho?

Umbhobho ngumbhobho ongenanto kunye necandelo lomnqamlezo ojikelezayo wokuhanjiswa kweemveliso. Iimveliso ziquka ulwelo, irhasi, iipellets, umgubo kunye nokunye. Igama lombhobho lisetyenziswa njengoko lahluliwe kwityhubhu ukuze lisetyenziswe kwiimveliso ze-tubular zobukhulu obuqhelekileyo obusetyenziselwa imibhobho kunye neenkqubo zokubhobhoza. Kule webhusayithi, imibhobho ehambelana neemfuno zedimensional:ASME B36.10Umbhobho wentsimbi odityanisiweyo kunye nongenamthungo kunyeASME B36.19I-Stainless Steel Pipe iya kuxoxwa.

Umbhobho okanye umbhobho?

Ehlabathini lemibhobho, imiqathango yombhobho kunye netyhubhu iya kusetyenziswa. Umbhobho uchongwa ngokuqhelekileyo ngokuthi "ubungakanani bombhobho oqingqiweyo" (NPS), kunye nobukhulu bodonga oluchazwa "inombolo yeShedyuli" (SCH).

Umbhobho uxelwa ngokwesiko ngedayamitha yayo yangaphandle (OD) kunye nobukhulu bodonga (WT), ebonakaliswa nokuba yi-Birmingham wire gage (BWG) okanye kwiwaka le-intshi.

Umbhobho: NPS 1/2-SCH 40 nokuba ukuya ngaphandle ububanzi 21,3 mm kunye ubukhulu eludongeni 2,77 mm.
Umbhobho: 1/2″ x 1,5 ilingana nangaphandle kwedayamitha eyi-12,7 mm kunye nobukhulu bodonga lwe-1,5 mm.

Iinqununu ezisetyenziselwa ityhubhu zikwi-Heat Exchangers, imigca yesixhobo kunye nokudibanisa okuncinci kwizixhobo ezifana ne-compressors, iibhoyili njl.

Izinto zoMbhobho

Iinkampani zobunjineli zineenjineli zemathiriyeli zokumisela izinto eziza kusetyenziswa kwiinkqubo zemibhobho. Uninzi lombhobho luyintsimbi ye-carbon (kuxhomekeke kwinkonzo) yenziwe kwimigangatho eyahlukeneyo ye-ASTM.

Umbhobho we-Carbon-steel womelele, uyadityaniswa, uyadityaniswa, unokusetyenzwa, unengqiqo, womelele kwaye usoloko unexabiso eliphantsi kunombhobho owenziwe ngezinye izinto. Ukuba umbhobho we-carbon-steel unokuhlangabezana neemfuno zoxinzelelo, ubushushu, ukumelana nokugqwala kunye nococeko, lukhetho lwendalo.

Umbhobho wentsimbi wenziwa kwi-cast-iron kunye ne-ductile-iron. Usetyenziso oluphambili lwelamanzi, igesi kunye nemibhobho yogutyulo.

Umbhobho wePlasitiki unokusetyenziselwa ukuhambisa ulwelo olusebenzayo oludlayo, kwaye uluncedo ngakumbi ekuphatha igesi ezonakalisayo okanye eyingozi kunye nokungxenga ii-asidi zezimbiwa.

Ezinye izinyithi kunye ne-Alloys umbhobho owenziwe ngobhedu, ilothe, i-nickel, ubhedu, i-aluminiyam kunye neentsimbi ezahlukeneyo ezingenasici zinokufumaneka ngokulula. Ezi mathiriyeli zibiza kakhulu kwaye zikhethwa ngokwesiqhelo mhlawumbi ngenxa yokunganyangeki kwazo kwikhemikhali yenkqubo, ukuTshintshela kobushushu obulungileyo, okanye ngenxa yokuqina kwazo kumaqondo obushushu aphezulu. I-alloys ye-Copper kunye ne-copper yendabuko kwimigca yesixhobo, ukulungiswa kokutya kunye nezixhobo zokuTshintshela ubushushu. Iintsimbi ezingenastainless ziya zisetyenziselwa ezi zinto.

Umbhobho onemigca

Ezinye izinto ezichazwe ngasentla, zidibaniswe ukwenza iinkqubo zemibhobho edibeneyo.
Ngokomzekelo, umbhobho we-carbon steel ungafakwa ngaphakathi kunye nezinto ezikwazi ukumelana nokuhlaselwa kweekhemikhali zivumela ukusetyenziswa kwayo ukuthwala i-corrosive fluids. I-Linings (i-Teflon®, umzekelo) ingasetyenziswa emva kokwenza umbhobho, ngoko ke kunokwenzeka ukwenza i-spools yombhobho yonke ngaphambi kokufakwa.

Ezinye iileyile zangaphakathi zingaba: iglasi, iiplastiki ezahlukeneyo, ikhonkrithi njl, kunye neengubo, njenge-Epoxy, i-Asphalt ye-Bituminous, i-Zink njl.inokunceda ukukhusela umbhobho wangaphakathi.

Izinto ezininzi zibalulekile ekumiseleni izinto ezifanelekileyo. Eyona nto ibalulekileyo kwezi zixinzelelo, ubushushu, uhlobo lwemveliso, imilinganiselo, iindleko njl.
