Ukuhlukaniswa kanye nempahla yepayipi yensimbi engenamthungo

Ipayipi lensimbi engenamthungo liwuhlobo lwepayipi elisetshenziswa kabanzi emkhakheni wezimboni. Inqubo yayo yokukhiqiza ayibandakanyi noma yikuphi ukushisela, yingakho igama elithi "seamless". Lolu hlobo lwepayipi ngokuvamile lwenziwa ngensimbi yekhwalithi ephezulu ye-carbon structural noma i-alloy steel ngokuginqika okushisayo noma okubandayo. Ipayipi le-carbon steel engenamthungo lisetshenziswa kabanzi emikhakheni eminingi efana nowoyela, igesi yemvelo, imboni yamakhemikhali, i-boiler, ukuhlola i-geological kanye nokukhiqizwa kwemishini ngenxa yesakhiwo salo esifanayo namandla, kanye nokumelana nokucindezela okuhle nokumelana nokushisa. Isibonelo, amapayipi ensimbi angenamthungo ama-boilers anengcindezi ephansi naphakathi asetshenziselwa ikakhulukazi ukukhiqiza amapayipi esitimu ashisa kakhulu, amapayipi amanzi abilayo kanye namapayipi esitimu ashisa kakhulu ama-boilers esitimela ama-boilers ahlukahlukene aphansi naphakathi. Futhi amapayipi ensimbi angenamthungo ama-boilers anengcindezi ephezulu asetshenziselwa ukukhiqiza amapayipi okushisa kwamanzi ama-boilers wamanzi anengcindezi ephezulu nangaphezulu. Ngaphezu kwalokho, amapayipi ensimbi yensimbi engenamthungo angasetshenziswa futhi ukwenza izingxenye zesakhiwo kanye nezingxenye zemishini, njengemishini yokushayela imoto, amafreyimu amabhayisikili, nezikafula zensimbi ekwakheni. Ngenxa yemininingwane yenqubo yokukhiqiza, amapayipi ensimbi e-carbon angenamthungo akwazi ukumelana nezingcindezi eziphakeme ngesikhathi sokusetshenziswa futhi awajwayele ukuvuza, ngakho abaluleke kakhulu ekudluliseni uketshezi.

Ukuhlukaniswa kwamapayipi ensimbi angenamthungo kusekelwe kakhulu ezintweni zokukhiqiza nokusetshenziswa. Ngokwendlela yokukhiqiza, amapayipi ensimbi angenamthungo angahlukaniswa abe izigaba ezimbili: ashisayo-ashisayo futhi abandayo (adonswe). Amapayipi ensimbi agingqelwe ashisayo ahlanganisa amapayipi ensimbi avamile, amapayipi ensimbi anomfutho ophansi naphakathi, amapayipi ensimbi anomfutho ophezulu wegazi, amapayipi ensimbi yengxubevange, amapayipi ensimbi engagqwali, amapayipi aqhekeka e-petroleum nezinye izinhlobo, kuyilapho abandayo (edonsa) amapayipi ensimbi angenamthungo ahlanganisa amapayipi ensimbi anezindonga ezincane zekhabhoni, ingxubevange yamapayipi ensimbi anezindonga ezincane, amapayipi ensimbi anezindonga ezincane ezingenasici kanye nezinsimbi ezihlukahlukene ezimise okukhethekile. amapayipi. Ukucaciswa kwamapayipi ensimbi angenamthungo kuvame ukuvezwa ngamamilimitha obubanzi obungaphandle nokuqina kodonga. Izinto ezisetshenziswayo zifaka insimbi yesakhiwo sekhabhoni ejwayelekile nesezingeni eliphezulu (efana ne-Q215-A kuya ku-Q275-A nensimbi eyi-10 kuye kwezingama-50), insimbi ye-alloy ephansi (efana no-09MnV, 16Mn, njll.), insimbi yengxubevange nensimbi engagqwali engamelana ne-asidi. . Ukukhethwa kwalezi zinto kuhlobene namandla, ukumelana nokucindezela kanye nokumelana nokugqwala kwepayipi, ngakho-ke kuzoba nezidingo ezihlukile zezinto ezisetshenziswayo ezimbonini ezahlukahlukene. Isibonelo, izinsimbi zekhabhoni ephansi ezifana nensimbi enguNo. 10 kanye noNo. . Ngaphezu kwalokho, amapayipi ensimbi angenamthungo kufanele alawule ikhwalithi eqinile phakathi nenqubo yokukhiqiza, okuhlanganisa ukuhlolwa kokwakheka kwamakhemikhali, ukuhlolwa kwempahla ngomshini, ukuhlolwa komfutho wamanzi, njll., ukuze kuqinisekiswe ukwethembeka nokuphepha kwawo ngaphansi kwezimo ezihlukahlukene zokusebenza. Inqubo yokukhiqiza yamapayipi ensimbi engenamthungo ye-carbon nayo ibaluleke kakhulu. Kubandakanya izinyathelo eziningi ezifana nokubhoboza, ukugoqa okushisayo, ukugoqa okubandayo noma ukudweba okubandayo kwama-ingots noma amashubhu aqinile, futhi isinyathelo ngasinye sidinga ukulawula okunembile ukuze kuqinisekiswe ikhwalithi yomkhiqizo wokugcina. Isibonelo, ukukhiqizwa kwamapayipi ensimbi angenamthungo agoqwe ashisayo kudinga ukushisisa i-tube billet ifike ku-1200 degrees Celsius, bese ibhoboza nge-perforator, bese kwakhiwa ipayipi lensimbi ngokusebenzisa i-roller oblique rolling, rolling eqhubekayo noma extrusion. Amapayipi ensimbi angenamthungo agoqeke abandayo adinga ukuthi i-tube billet ifakwe emanzini anosawoti futhi igcotshwe ngaphambi kokuba igoqwe (idonswe) ebandayo ukuze ifinyelele usayizi nokuma okufunayo. Lezi zinqubo zokukhiqiza eziyinkimbinkimbi aziqinisekisi kuphela ikhwalithi yangaphakathi yepayipi lensimbi engenamthungo, kodwa futhi linikeza ukunemba okungcono kobukhulu kanye nokuqedwa kwendawo. Ekusetshenzisweni okungokoqobo, amapayipi ensimbi e-carbon angenamthungo asetshenziswa kakhulu ezimbonini eziningi ezifana nowoyela, igesi, imboni yamakhemikhali, ugesi, ukushisa, ukongiwa kwamanzi, ukwakhiwa kwemikhumbi, njll. ngenxa yokusebenza kwawo okuhle kakhulu nokuthembeka. Bayingxenye ebalulekile yemboni yesimanje. Kungakhathaliseki ukuthi kumazingeni okushisa aphezulu kanye nasezindaweni ezinengcindezi ephezulu noma emithonjeni yezindaba ebolayo, amapayipi ensimbi ekhabhoni angenamthungo angabonisa ukusebenza kwawo okuhle kakhulu futhi anikeze iziqinisekiso eziqinile zokusebenza okuphephile kwezinhlelo zezimboni ezihlukahlukene.

Ububanzi bamapayipi ensimbi yensimbi engenamthungo bungasukela ku-DN15 kuye ku-DN2000mm, ukushuba kodonga kuyahlukahluka kusuka ku-2.5mm kuya ku-30mm, kanti ubude buvamise ukuba phakathi kuka-3 no-12m. Le mingcele yobukhulu ivumela amapayipi ensimbi e-carbon angenamthungo ukuthi asebenze ngokuzinzile ngaphansi kwengcindezi ephezulu kanye nezimo zokushisa eziphezulu, kuyilapho eqinisekisa ukwethembeka kwawo ngesikhathi sokuthutha nokufakwa. Ngokwezinga le-GB/T 17395-2008, ubukhulu, ukuma, isisindo kanye nokuphambuka okuvumelekile kwamapayipi ensimbi angenamthungo kulawulwa ngokuqinile ukuze kuqinisekiswe ikhwalithi nokuphepha komkhiqizo. Uma ukhetha amapayipi e-carbon steel angenamthungo, kubalulekile ukucabangela ububanzi bawo bangaphakathi, ububanzi bangaphandle, ubukhulu nobude, okuyizici ezibalulekile ekunqumeni ukusebenza kwepayipi. Isibonelo, ububanzi bangaphakathi bunquma ubukhulu besikhala ukuze uketshezi ludlule, kuyilapho ububanzi obungaphandle nobukhulu buhlobene eduze nomthamo othwala ukucindezela wepayipi. Ubude buthinta indlela yokuxhuma yepayipi kanye yinkimbinkimbi yokufakwa.
