Yini iPipe?

Ipayipi iyishubhu elingenalutho elinesiphambano esiyindilinga sokuhambisa imikhiqizo. Imikhiqizo ihlanganisa uketshezi, igesi, ama-pellets, izimpushana nokunye. Igama elithi ipayipi lisetshenziswa njengoba lihlukaniswa neshubhu ukuze lisebenze emikhiqizweni yamashubhu enobukhulu obuvame ukusetshenziselwa amapayipi namasistimu amapayipi. Kule webhusayithi, amapayipi ahambisana nezidingo ze-dimensional:I-ASME B36.10Ipayipi lensimbi elishiselwe futhi elingenamthungo kanyeI-ASME B36.19Kuzoxoxwa ngepayipi lensimbi engagqwali.

Ipayipi noma iThubhu?

Emhlabeni wamapayipi, amagama athi ipayipi neshubhu azosetshenziswa. Ipayipi ngokuvamile lihlonzwa ngokuthi "Usayizi Wepayipi Lokuqamba" (NPS), ngokuqina kodonga kuchazwa "inombolo yoHlelo" (SCH).

Ishubhu ngokuvamile icaciswa ngobubanzi bayo bangaphandle (OD) nogqinsi lwedonga (WT), ivezwa nge-Birmingham wire gage (BWG) noma ngezinkulungwane zamayintshi.

Ipayipi: I-NPS 1/2-SCH 40 ilingana nobubanzi obungu-21,3 mm obunodonga obungu-2,77 mm.
Ishubhu: 1/2″ x 1,5 ilingana nangaphandle 12,7 mm enogqinsi oluyi-1,5 mm.

Ukusetshenziswa okuyinhloko kweshubhu kuku-Heat Exchanger, izintambo zezinsimbi kanye noxhumano oluncane emishinini efana nama-compressor, ama-boiler njll.

Izinto zePipe

Izinkampani zobunjiniyela zinonjiniyela bezinto zokunquma izinto ezizosetshenziswa ezinhlelweni zamapayipi. Amapayipi amaningi awensimbi ye-carbon (kuye ngokuthi isevisi) akhiqizwa ngamazinga ahlukene e-ASTM.

Ipayipi lensimbi ye-Carbon liqinile, liyathandeka, liyashiseka, liyasebenziseka, ngokunengqondo, liqinile futhi lihlala lishibhile kunepayipi elenziwe ngezinye izinto. Uma ipayipi le-carbon-steel lingahlangabezana nezidingo zokucindezela, izinga lokushisa, ukumelana nokugqwala kanye nenhlanzeko, kuyisinqumo semvelo.

Ipayipi lensimbi lenziwe nge-cast-iron kanye ne-ductile-iron. Izindlela eziyinhloko ezisetshenziswayo ezamanzi, igesi nezintambo zokukhuculula indle.

Ipayipi lepulasitiki lingase lisetshenziselwe ukudlulisa uketshezi oludlayo, futhi luwusizo ikakhulukazi ekuphatheni amagesi abolayo noma ayingozi futhi ahlambulule ama-acid amaminerali.

Amanye amapayipi e-Metals and Alloys enziwe ngethusi, umthofu, i-nickel, ithusi, i-aluminium nezinsimbi ezihlukahlukene ezingenasici zingatholakala kalula. Lezi zinto zibiza kakhulu futhi zikhethwa ngokuvamile ngenxa yokumelana kwazo nokugqwala kukhemikhali yenqubo, Ukudlulisa Ukushisa kwazo okuhle, noma ngenxa yamandla azo aqinile emazingeni okushisa aphezulu. Ama-alloys ethusi nawethusi angokwesiko olayini bezinsimbi, ukucubungula ukudla kanye nemishini Yokudlulisa Ukushisa. Izinsimbi ezingenasici ziya ngokuya zisetshenziselwa lezi.

Ipayipi Elilayishiwe

Ezinye izinto ezichazwe ngenhla, zihlanganisiwe ukuze zenze amasistimu wamapayipi anemigqa.
Isibonelo, ipayipi le-carbon steel lingafakwa ngaphakathi ngaphakathi ngezinto ezikwazi ukumelana nokuhlaselwa kwamakhemikhali okuvumela ukusetshenziswa kwalo ukuthwala uketshezi olubolayo. Ama-Linings (i-Teflon®, isibonelo) angasetshenziswa ngemva kokwakhiwa kwamapayipi, ngakho-ke kungenzeka ukwenza ama-spool amapayipi aphelele ngaphambi kokwendlalwa.

Ezinye izendlalelo zangaphakathi zingaba: ingilazi, amapulasitiki ahlukahlukene, ukhonkolo njll., futhi izigqoko, njenge-Epoxy, i-Bituminous Asphalt, i-Zink njll. kungasiza ukuvikela ipayipi yangaphakathi.

Izinto eziningi zibalulekile ekunqumeni impahla efanele. Okubaluleke kakhulu kulokhu ukucindezela, izinga lokushisa, uhlobo lomkhiqizo, ubukhulu, izindleko njll.
