I-L245 Pipeline Steel, Ipayipi elivamile elikhipha uwoyela, igesi, namanzi liwakhiphe emhlabathini liwalethe embonini kawoyela negesi.Ipayipi lepayipi lihlanganisa ipayipi elingenamthungo kanye nepayipi lensimbi elishiselwe, umkhawulo wepayipi uwumkhawulo oyisicaba, umkhawulo ocushiwe kanye nokuphela kwesokhethi;Imodi yokuxhuma i-welding yokuphela, uxhumano lwe-hoop, uxhumano lwesokhethi nokunye

Ngokuthuthukiswa kobuchwepheshe bepuleti lensimbi yepayipi kanye nenqubekela phambili yokwakhiwa kwamapayipi ashiselwe, ubuchwepheshe bokushisela, uhla lwesicelo sepayipi ngepayipi elihlanganisiwe ekwandeni kancane kancane, ikakhulukazi izinzuzo zesigaba esikhulu sepayipi elihlanganisiwe zibonakala kakhudlwana, nezici zezindleko, ipayipi elishiselwe bekulokhu kuvelele emkhakheni wepayipi lomugqa, okhawulela ukuthuthukiswa kwepayipi lensimbi engenamthungo.Ngo-2004, ukukhiqizwa kwepayipi elingenamthungo kulinganiselwa ku-400,000 t, izinga lensimbi lihlanganisa i-X42-70, futhi izinhlobo zingamapayipi asogwini kanye nepayipi elihamba ngaphansi kolwandle.

I-L245 Pipeline Steel, Inqubo yokushisisa ye-Microalloying isetshenziswa ekukhiqizeni, izindleko zokukhiqiza ishubhu yensimbi engenamthungo iphakeme kakhulu kuneshubhu elishiselwe, futhi ngokuthuthukiswa kwebanga lensimbi, elifana ne-X80 nangaphezulu komkhawulo wepayipi lensimbi ebangeni elilingana nekhabhoni, inqubo evamile ye-tube engenamthungo inzima ukuhlangabezana nezidingo zabasebenzisi;Umkhiqizi ngamunye wepayipi lengxubevange engu-12Cr1moV wenza umsebenzi wocwaningo lwesayensi ukuze athuthukise ukumelana nokugqwala kwepayipi lawo kanye nokusebenza okuzinzile endaweni enezinga lokushisa eliphansi neliphezulu.

Okubalulekile kwepayipi:L245, L360, A53, J55, N80, X42, X46, X52, X56, X60, X65, X70

Ukucaciswa kwepayipi:∮60-630×1.53-40

I-L245 Pipeline Steel, He Ratio Of Solution

Ukutholwa kwamanje kwe-Eddy kwepayipi le-Changsha kusebenza kuphela ezintweni zokuqhuba.Uma kusetshenziswa izinto ezingezona e-conductive, i-vortex shape yamanje ayikwazi ukunxenxwa futhi i-eddy current ayikwazi ukusetshenziselwa ukutholwa.Ukuhlolwa kwamanje kwe-Eddy kulungele ikakhulukazi ukuhlolwa kwendawo engaphezulu naseduze kwezinto ezisetshenziswayo.Ukuhlola kwamanje kwe-Eddy akudingi ukuhlanganisa.Inkambu ye-electromagnetic ejabuliswa ekuhlolweni kwamanje kwe-eddy empeleni iyigagasi kazibuthe elinezici zegagasi nezinhlayiyana, ngakho-ke i-probe (ikhoyili) kanye nocwecwe lokusebenza kungadluliswa ngaphandle kokuhlangana, ukuze kutholakale umuntu ongathintana naye.Lokhu kungcono kunokutholwa nge-ultrasonic.Ngenxa yokuthi i-ultrasonic wave ye-low pressure boiler tube iyigagasi lomshini, ingahamba kuphela ngempahla.Ngakho-ke, ukutholwa kwe-ultrasonic kufanele kuhlanganiswe phakathi kwe-probe ne-workpiece.Ukuhlola kwamanje kwe-Eddy kungafinyelela ukuhlolwa okusheshayo nokuzenzakalelayo.Ukuhlolwa kwamanje kwe-Eddy kungafaneleka ukutholwa kwezinsimbi zokushisa okuphezulu ngenxa ye-conductivity yazo kagesi emazingeni okushisa aphezulu.Ukutholwa kokugeleza kwepayipi le-Changsha nakho kulungele ukutholwa kwezinto ezimise okukhethekile, inqobo nje uma ikhoyili yenziwe yaba izimo ezihlukahlukene.Okuvamise ukusetshenziselwa ukwenza amapayipi anezinhlobo ezi-3 ze-brinell, rockwell, Vickers hardness.Ipayipi le-Changsha "Ipayipi lensimbi elingenamthungo le-Boiler yokucindezela okuphansi nokuphakathi".Kunezinhlobo ezingama-43 zokucaciswa kwepayipi le-changsha lazo zonke izinhlobo zezakhiwo zokubhayela, ezinobubanzi obuyi-10 ~ 426mm.Kunezinhlobo ezingama-29 zokujiya kodonga kusuka ku-1.5 mm kuya ku-26mm.Kodwa-ke, ububanzi obungaphandle nobukhulu bodonga lwepayipi lesitimu esishisa kakhulu, ipayipi elikhulu lentuthu, ipayipi elincane lentuthu kanye nepayipi lezitini le-arch elisetshenziswa kubhayela wesitimela kubalulwe ngenye indlela.Ububanzi bangaphandle bepayipi le-changsha bungama-22 ~ 530mm, futhi ukujiya kodonga kungu-20 ~ 70mm.Abandayo adonswe (okubandayo rolling) tube ububanzi 10 ~ 108mm, udonga ukujiya 2.0 ~ 13.0mm.Ikhwalithi yokubukeka: ukuqhekeka, ukugoqa, ukugoqa, ukukhwabanisa, ukuhlukaniswa kanye nemibimbi akuvunyelwe endaweni yangaphakathi nangaphandle yepayipi yensimbi.Lezi zinkinga kufanele ziqedwe ngokuphelele.Ukujula kokususa akumele kudlule ukuchezuka okuyinegethivu kogqinsi oluvamile lodonga, futhi ukujiya kwangempela kodonga endaweni evulekile akumele kube ngaphansi kobukhulu obuncane obuvunyelwe bodonga.Isihluthulelo siwukusebenzisa izindlela ezahlukene ngokuya ngezimo ezihlukene, njengokwamukela izinto ze-adiabatic kanye ne-refractory ukuvimba ilangabi ekushiseni isakhiwo sensimbi ngokuqondile, ukunciphisa ijubane lokudlulisa ukushisa nokubambezela isikhathi sokukhuphuka kwezinga lokushisa namandla okwenza buthaka isakhiwo sensimbi. .Kodwa kungakhathaliseki ukuthi iyiphi indlela, isimiso siyefana.Ukumboza okungashiyo kuwuhlobo lwezinyathelo zobuchwepheshe ezithuthuke kakhulu zokuvikela umlilo okwamanje.Ngenxa yethonya lezinto ezingcolile kwikhwalithi yepayipi lepayipi le-Changsha, imikhiqizo yezinga eliphezulu inezidingo eziqinile kakhulu zokulawula izakhi eziyingozi kanye nokufakwa kwepayipi lepayipi le-Changsha.Kuyadingeka ukulawula okuqukethwe kwezakhi ezihlukahlukene zokungcola ezingeni eliphansi kakhulu ngangokunokwenzeka, futhi inqubo yokucwenga ngaphandle kwesithando somlilo ivame ukusetshenziswa ekukhiqizeni ukuze kuqinisekiswe ukuhlanzeka kwayo.Izinga lokushisa elijwayelekile le-boiler tube lingaphansi kuka-350 ℃, ipayipi lasekhaya lenziwa ikakhulukazi nge-no.10, 20 carbon bonded steel Changsha ipayipi noma abandayo edonsa ipayipi.
