Ipayipi Lensimbi Elishiselwe Ikhwalithi ephezulu
Ipayipi Lensimbi Elishiselwe Ikhwalithi ephezulu
Izinto ezivamile zamapayipi ashiselwe yilezi: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni1018b, 9, njll.
Okungenalutho okusetshenziselwa ipayipi lensimbi elishiselwe ipuleti lensimbi noma i-strip steel.Ngenxa yezinqubo ezahlukene zokushisela, ihlukaniswe ipayipi elishiselwe esithandweni, ipayipi kagesi (ukumelana ne-welding) kanye nepayipi elizenzakalelayo le-arc elishiselwe.Ngenxa yamafomu awo ahlukene okushisela, ahlukene abe ipayipi elithungelwe ngomthungo oqondile kanye nepayipi elishiselwe okuvunguza.Ngenxa yokuma kwayo kokuphela, ihlukaniswe yaba ipayipi eliyisiyingi elishiselwe futhi elimise okukhethekile (isikwele, flat, njll.) elishiselwe ipayipi.Amapayipi ashiselwe ahlukaniswe ngezinhlobo ezilandelayo ngenxa yezinto zawo ezihlukene kanye nokusetshenziswa kwawo:
I-GB / t3091-2008 (ipayipi lensimbi elishiselwe ukuthutha uketshezi olunengcindezi ephansi): isetshenziselwa kakhulu ukuthutha amanzi, igesi, umoya, uwoyela, ukushisisa amanzi ashisayo noma isitimu kanye nolunye uketshezi olujwayelekile oluphansi kanye namapayipi ngezinye izinjongo.Izinto zayo ezimele ziyi-Q235 grade a steel.
I-GB / t14291-2006 (ipayipi lensimbi elishiselwe ukuthutha uketshezi lwezimayini): isetshenziselwa ikakhulukazi ipayipi lensimbi elithungelwe ngomthungo oqondile wokucindezela komoya emayini, ukudonsa amanzi kanye nokukhipha igesi ku-shaft.Izinto zayo ezimele ziyi-grade Q235A nensimbi engu-B.
I-GB / t12770-2002 (ipayipi lensimbi engagqwali elishiselwe isakhiwo sokusebenza): ikakhulukazi esetshenziselwa imishini, imoto, ibhayisikili, ifenisha, umhlobiso wehhotela nezindawo zokudlela kanye nezinye izingxenye zemishini nezingxenye zesakhiwo.Izinto ezisetshenziswayo ezimele i-0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, njll.
I-GB / t12771-1991 (ipayipi lensimbi engagqwali elishiselwe ukuthutha uketshezi): isetshenziselwa kakhulu ukuthutha imidiya egqwalayo enengcindezi ephansi.Izinto ezisetshenziswayo ezimele i-0Cr13, 0Cr19Ni9, 00cr19ni11, 00Cr17, 0cr18ni11nb, 0017cr17ni14mo2, njll.
Ngaphezu kwalokho, amapayipi ensimbi engagqwali ashiselwe umhlobiso (GB / T 18705-2002), ashiselwe insimbi engagqwali amapayipi umhlobiso yezakhiwo (JG / T 3030-1995), futhi eziphothene amapayipi ensimbi for exchangers ukushisa (yb4103-2000).Ipayipi ehlanganisiwe ye-Longitudinal inezinzuzo zenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi kanye nentuthuko esheshayo.Amandla epayipi elishiselwe okuvunguza ngokuvamile aphakeme kunalawo amapayipi ashiselwe aqondile.Ingakhiqiza ipayipi elishiselwe elinobubanzi bepayipi elikhudlwana elingenalutho eliwumngcingo, kanye nepayipi elishiselwe elinobubanzi bepayipi elihlukene elingenalutho lobubanzi obufanayo.Nokho, uma kuqhathaniswa nepayipi lomthungo eliqondile elinobude obufanayo, ubude be-weld bukhuphuka ngo-30 ~ 100%, futhi isivinini sokukhiqiza siphansi.Ukuqaqa impahla eluhlaza - ukulinganisa - ukugunda kanye nokushisela - iluphu - ukwakha - Ukushisela - ukususwa kobuhlalu obushisiwe ngaphakathi nangaphandle - ukulungiswa kwangaphambili - ukwelashwa kokushisa okufakwayo - ukulinganisa nokuqondisa - ukuhlolwa kwamanje kwe-eddy - ukusika - ukuhlolwa kwamanzi - Pickling - ukuhlolwa kokugcina (okuqinile control) - Ukupakisha - ukuthunyelwa.Imikhiqizo isetshenziswa kabanzi kubunjiniyela bamanzi kampompi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo kanye nokwakhiwa kwamadolobha.Ingenye yemikhiqizo engu-20 ebalulekile eyakhiwe eShayina.
Ukuhlinzekwa kwamanzi kanye nokukhipha amanzi.Ngokudluliswa kwegesi: igesi, isitimu kanye negesi ye-petroleum ewuketshezi.
Njengepayipi lokushayela inqwaba nebhuloho;Amapayipi echweba, umgwaqo, isakhiwo sebhilidi, njll.
