Ipayipi lensimbi elingenamthungo libhobozwa yiyo yonke insimbi eyindilinga, futhi ipayipi lensimbi elingashisiseli phezulu libizwa ngokuthi ipayipi lensimbi engenamthungo. Ngokwendlela yokukhiqiza, ipayipi lensimbi elingenamthungo lingahlukaniswa libe ipayipi lensimbi elingenamthungo eligoqwe elishisayo, ipayipi lensimbi elibandayo eligoqelwe elibandayo, ipayipi lensimbi elibandayo elidonswayo, ipayipi lensimbi elingenamthungo, ukugqekeza kwepayipi nokunye. Ngokwesimo sesigaba, ipayipi yensimbi engenamthungo ihlukaniswe yaba izinhlobo ezimbili: nxazonke futhi ezimise. Ubukhulu obukhulu bungama-900mm kanti ubukhulu obuncane bungama-4mm. Ngokusho kokusetshenziswa okuhlukene, kukhona amapayipi ensimbi angenamthungo aminyene kanye namapayipi ensimbi angenamthungo. Ipayipi lensimbi engenamthungo lisetshenziselwa ikakhulukazi ipayipi lokumba le-petroleum geological, petrochemicalipayipi eliqhekeka, ipayipi le-boiler, ipayipi elithwalayo kanyeipayipi yensimbi yesakhiwo enembayo ephezuluezezimoto, ogandaganda kanye nezokundiza. 

Ngokusho ukusetshenziswa ihlukaniswe inhloso jikelele (amanzi, igesi amapayipi kanye izingxenye zesakhiwo, izingxenye mechanical) kanye ekhethekile (for boilers, ukuhlola geological, ama-bearings, ukumelana acid, njll) izigaba ezimbili.

Inhloso evamile yepayipi lensimbi engenamthungo igoqwa ngensimbi evamile ye-carbon structural, insimbi yesakhiwo sengxubevange ephansi noma insimbi yesakhiwo sengxubevange, futhi inomphumela omkhulu kakhulu, osetshenziswa kakhulu njengepayipi noma ingxenye yesakhiwo yokudlulisa uketshezi. Kunezinhlobo eziningi zamapayipi angenamthungo ngezinjongo ezikhethekile, njengamapayipi angenamthungo abhayela, amapayipi amandla amakhemikhali, amapayipi angenamthungo we-geological kanye namapayipi angenamthungo ka-petroleum. Ipayipi lensimbi elingenamthungo linendawo ephambanayo engenalutho futhi lisetshenziswa kakhulu njengepayipi lokudlulisa uketshezi, njengamapayipi okuhambisa uwoyela, igesi yemvelo, igesi, amanzi nezinye izinto eziqinile.

Inqubo yokukhiqiza ipayipi lensimbi engenamthungo:

① Inqubo yokukhiqiza eyinhloko yepayipi lensimbi elingenamthungo eligoqelwe ngokushisayo (△ Inqubo yokuhlola enkulu) : 

Ukulungiselela nokuhlola △→ Ukushisa → ukubhoboza → Ukugoqa → ukushisisa kabusha → Ukulinganisa ubukhulu → Ukwelashwa kokushisa △→ Ukuqondisa → Ukuqeda → Ukuhlola △ (okungonakali, ngokomzimba namakhemikhali, ukuhlolwa kwetafula) → indawo yokugcina

② Inqubo yokukhiqiza eyinhloko yepayipi lensimbi eligoqiwe (elidwetshiwe) elibandayo:

Ukulungiselela okungenalutho → ukugcotshwa kwe-pickle → Ukugoqa okubandayo (umdwebo) → Ukwelashwa kokushisa → ukuqondisa → ukuqeda → ukuhlola

Inqubo evamile yokukhiqiza ipayipi lensimbi engenamthungo ingahlukaniswa ngezinhlobo ezimbili zomdwebo obandayo kanye nokuginqika okushisayo, inqubo yokukhiqiza ipayipi lensimbi engenamthungo ebandayo ngokuvamile iyinkimbinkimbi kakhulu kunokuginqika okushisayo, i-tube billet kuqala ukwenza i-roller emithathu eqhubekayo, i-extrusion ngemva kokuhlolwa kokulinganisa. , uma indawo engaphezulu ingaphenduli emfantwini ngemva kweshubhu eliyindilinga elizosikwa umshini wokusika, ukusika ukukhula okungaba imitha eyodwa kungenalutho. Bese ufaka inqubo yokudonsa, i-annealing nge-acidic liquid pickling, i-pickling kufanele inake ukuthi kukhona inani elikhulu lama-bubbles ebusweni, uma kunenqwaba yamabhamuza, okubonisa ukuthi ikhwalithi yepayipi yensimbi ayikwazi ukuhlangabezana izindinganiso ezihambisanayo. Ukubonakala kwepayipi lensimbi engenamthungo eligoqelwe ngokubanda lifushane kunepayipi lensimbi eligoqelwe elishisayo eligoqelwe, ugqinsi lwepayipi lensimbi eligoqeke ngokubanda ngokuvamile lincane kunepayipi lensimbi eligoqelwe elishisayo, kodwa ubuso bubukeka bukhanya kakhulu ipayipi lensimbi engenamthungo enezindonga eziwugqinsi, indawo engaphezulu ayimbi kakhulu, futhi izinga alilona i-burr eningi kakhulu.

Isimo sokulethwa kwepayipi lensimbi engenamthungo eligoqwe elishisayo ngokuvamile lilethwa ngemva kokwelashwa kokushisa okugoqiwe okushisayo. Ipayipi lensimbi elingenamthungo elishisayo eligoqelwe ngemuva kokuhlolwa kwekhwalithi ukuze lidlule ekukhethweni okuqinile kwabasebenzi, ngemuva kokuhlolwa kwekhwalithi ukuze kuqhutshwe uwoyela ongaphezulu, bese kulandelwa inani lokuhlolwa okubandayo komdwebo, ukwelashwa okugoqayo okushisayo ukwenza ukuhlolwa kokubhobozwa. , uma ukunwetshwa kwembobo kukukhulu kakhulu ukuthi kungaqondisa. Ngemva kokuqondisa, ithunyelwa emshinini wokubona amaphutha ngedivayisi yokudlulisela ukuze kuhlolwe amaphutha, futhi ekugcineni ilebulwe, ifomethwe futhi ibekwe endaweni yokugcina impahla.

Ishubhu eliyindilinga alinalutho → ukushisisa → ukubhobozwa → ukugoqeka kwe-skew yamaroll amathathu, ukugoqeka okuqhubekayo noma ukukhipha → Ukuhlubula → ukusika (noma ukunciphisa) → Ukupholisa → ukuqondisa → ukuhlolwa komfutho wamanzi (noma ukuhlola) → Ukumaka → Ipayipi lensimbi engenamthungo endaweni yokugcina lenziwe ngensimbi ingot noma ishubhu eliqinile elingenalutho ngokubhoboza ukuze lenze ithubhu le-capillary, bese kuba ukugoqeka okushisayo, ukugoqeka okubandayo noma umdwebo obandayo. Ukucaciswa kwepayipi lensimbi engenamthungo kuvezwa ububanzi obungaphandle * ukushuba kodonga lwamamilimitha.

Ububanzi bangaphandle bepayipi elingenamthungo eligoqwe elishisayo ngokuvamile bukhulu kuno-32mm, ukujiya kodonga buyi-2.5-200mm, ububanzi obungaphandle bepayipi lensimbi eligoqwe elibandayo bungaba ngu-6mm, ukujiya kodonga kungaba ngu-0.25mm, ububanzi obungaphandle wepayipi elincanyana elincane lingaba ngu-5mm, ukujiya kodonga kungaphansi kuka-0.25mm, futhi ukunemba kosayizi kuphakeme kunalelo lepayipi eligoqwe elishisayo elingenamthungo.
