Iwaranti yomkhiqizi wepayipi lesakhiwo sensimbi ye-Q345B
Ochungechungeni lwamapayipi ensimbi angenamthungo, kukhona into ebizwa nge-Q345B ipayipi lensimbi engenamthungo, eyingxenye yochungechunge lwe-alloy ephansi. Phakathi kwezinto eziphansi ze-alloy, le nto ivame kakhulu. Ipayipi lensimbi elingenamthungo le-Q345B lalibizwa ngepayipi lensimbi elingenamthungo elingu-16Mn. Ziningi izindlela zokuhlukanisa. Ngokwenqubo yokukhiqiza, kukhona: ipayipi elishisayo eligoqiwe elingenamthungo kanye nepayipi elibandayo eligoqiwe elingenamthungo. Ngokwenhloso, kukhona: ipayipi lensimbi elingenamthungo lesakhiwo esijwayelekile, ipayipi lensimbi elingenamthungo lokudlulisa uketshezi, ipayipi lensimbi elingenamthungo lebhoyela elinomfutho ophakathi nendawo kanye nepayipi lensimbi elingenamthungo kubhayela wengcindezi ephezulu. Ngokusho kokuqukethwe, kukhona: ipayipi lensimbi esezingeni eliphakeme ye-carbon structural steel, ipayipi lensimbi elingenamthungo elinengxubevange yensimbi engenamthungo kanye nepayipi lensimbi engenamthungo. Ipayipi lensimbi engenamthungo lisetshenziswa kabanzi, Lingacutshungulwa libe izingxenye zemishini, ezisetshenziselwa ukuthutha uketshezi noma igesi, lisetshenziswe njengama-drive bearings, futhi lisetshenziselwa ukwakha izakhiwo eziqinile zesakhiwo.
Izinga eliphezulu langaphandle le-Q345B lepayipi lensimbi elingenamthungo yi-gb709 futhi izinga lokuphatha langaphakathi yi-GB / t1591-94.
Indlela yokuqamba iyafana ne-Q345B.
Ngenxa yokuqaliswa kwezinga, lolu hlobo lwe-steel plate luvunyelwe ukulethwa ngokubekezelelana okungalungile.
I-Q345 ipayipi yensimbi engenamthungo iwuhlobo lwempahla yepayipi lensimbi. U-Q umele isivuno salolu hlelo lokusebenza. Okulandelayo i-345 ibhekisela enanini lesivuno salokhu kwaziswa, okungaba ngu-345. Inani lesivuno liyancipha ngokukhula kobukhulu bezinto ezibonakalayo.
Q345A, awukho umthelela;
Q345B, 20 ° umthelela ojwayelekile wokushisa;
Q345C, 0 degree umthelela;
Q345D, kuyinto - 20 degree umthelela;
I-Q345E ingu-40 degree umthelela.
Emazingeni okushisa omthelela ahlukene, amanani omthelela nawo ahlukile.
Q345A, Q345B, Q345C, Q345D, Q345E, Lona umehluko wamabanga, omelela ngokuyinhloko ukuthi izinga lokushisa lomthelela lihlukile.
I-Q345B ipayipi yensimbi engenamthungo iwuhlobo lwezinto zensimbi, ezingahlukaniswa zibe yi-Q345A, Q345B, Q345C, Q345D kanye ne-Q345E ngokusho kwebanga. Ezikumelelayo ukuthi izinga lokushisa lomthelela lihlukile. Q345A, awukho umthelela; Q345B, 20 ° umthelela ojwayelekile wokushisa; Q345C, 0 degree umthelela; Q345D, kuyinto - 20 degree umthelela; I-Q345E ingu-40 degree umthelela.
Ihlukaniswa ngenqubo yokukhiqiza: ipayipi eligoqiwe elishisayo elingenamthungo kanye nepayipi eligoqiwe elibandayo elingenamthungo.
Ngokwesigaba sokusetshenziswa, kukhona: ipayipi lensimbi elingenamthungo lesakhiwo esijwayelekile, ipayipi lensimbi engenamthungo lokudlulisa uketshezi, ipayipi lensimbi elingenamthungo lebhayela elinomfutho ophakathi nendawo kanye nepayipi lensimbi engenamthungo kubhayela onengcindezi ephezulu.
Ngokwempahla: ipayipi lensimbi elingenamthungo elisezingeni eliphezulu lekhabhoni lensimbi, ipayipi lensimbi lensimbi elingenamthungo eliphansi, ipayipi lensimbi elingenamthungo.
1. Ipayipi le-Structural Seamless (GB / t8162-2018) iyipayipi yensimbi engenamthungo yesakhiwo esijwayelekile kanye nesakhiwo somshini.
2. Ipayipi lensimbi elingenamthungo lokuthutha uketshezi (GB / t8163-2018) iyipayipi lensimbi elingenamthungo elisetshenziselwa ukuthutha amanzi, uwoyela, igesi nolunye uketshezi.
3. Ipayipi lensimbi elingenamthungo likabhayela wengcindezi ephansi nemaphakathi (gb3087-2018) iyipayipi lensimbi yekhwalithi ephezulu yensimbi egoqwe futhi ebandayo (egoqiwe) engenamthungo esetshenziselwa ukwakha ipayipi lesitimu esishisa kakhulu, ipayipi lamanzi abilayo kubhayela wokucindezela okuphansi nokuphakathi. , ipayipi le-steam elishisa kakhulu kanye nepayipi lezitini ze-arch le-boiler yesitimela.
4. Ipayipi lensimbi elingenamthungo likabhayela onengcindezi ephezulu (gb5310-2018) iyinsimbi yekhwalithi ephezulu yekhabhoni, insimbi eyingxubevange kanye nepayipi lensimbi engenamthungo elingashisi elisetshenziselwa ukwakha indawo yokushisisa yebhayela yamanzi enengcindezi ephezulu nangaphezulu.
