27SiMN Ucime kwaye Ubushushu Steel Pipe API Series Pipeline Steel Umbhobho Umbhobho Carbon Steel Round Pipe

Ingcaciso yeMveliso

Umbhobho wentsimbi yekhabhoni okanye umbhobho wentsimbi wekhabhoni wenziwe ngentsimbi yentsimbi okanye umbhobho oqinileyo ongenanto ngokugqobhoza, emva koko wenziwe ngokuqengqeleka okushushu, ukuqengqeleka okubandayo okanye umzobo obandayo. Umbhobho wentsimbi yeCarbon udlala indima ebalulekileyo kwishishini lombhobho wentsimbi yaseTshayina. Izinto ezikrwada zombhobho wentsimbi yekhabhoni yityhubhu engqukuva engenanto. Umbhobho ojikelezayo ongenanto unqunywe kwaye ucutshungulwe ngomatshini wokusika, kwaye ungenanto kunye nokukhula malunga ne-1m ithunyelwa kwisithando somlilo ukufudumeza ngebhanti yokuhambisa. I-billet ithunyelwa kwiziko ukuze ifudunyezwe kwiqondo lokushisa malunga ne-1200 degrees Celsius. Amafutha yihydrogen okanye iacetylene. Ukulawulwa kweqondo lokushisa kwisithando somlilo yingxaki ephambili. Emva kokuba i-tube billet ejikelezayo ikhutshwe kwisithando somlilo, kufuneka ihlatywe nge-piercer pressure piercer. Ngokuqhelekileyo, oyena mgqobhozi uxhaphakileyo ngumbhobhozo we-conical roll. Lo mbhobhozo unomgangatho ophezulu wemveliso, umgangatho omhle wemveliso, ukwandiswa okukhulu kwe-perforation kwaye unokugqoka iindidi zentsimbi. Emva kokubhoboza, i-tube ejikelezileyo engenanto iqhutywe ngokulandelelana ngokuqengqeleka kwe-roll cross rolling, i-rolling eqhubekayo okanye i-extrusion. Emva kwe-extrusion, susa umbhobho ukwenzela ukulinganisa. Umatshini wokulinganisa ujikeleza kwi-embryo yentsimbi ngesantya esiphezulu ngokusebenzisa i-conical drill ukwenza umbhobho wentsimbi. Ububanzi bangaphakathi bombhobho wentsimbi buchongwa bubude obungaphandle bedayamitha yokulinganisa umatshini wokulinganisa. Emva kokulinganisa, umbhobho wensimbi ungena kwinqaba yokupholisa kwaye upholiswe ngokutshiza kwamanzi. Emva kokupholisa, umbhobho wensimbi uya kulungiswa. Emva kokulungiswa, umbhobho wensimbi uthunyelwa kwi-metal flaw detector (okanye uvavanyo lwe-hydrostatic) ngebhanti yokuhambisa ukukhangela impazamo yangaphakathi. Ukuba kukho ukuqhekeka, iibhubhu kunye nezinye iingxaki ngaphakathi kombhobho wensimbi, ziya kufunyanwa. Imibhobho yensimbi kufuneka ikhethwe ngokungqongqo ngesandla emva kokuhlolwa komgangatho. Emva kokuba umbhobho wensimbi uhlolwe, inombolo, inkcazo, inombolo yebhetshi yokuvelisa, njl njl. Kuya kutshizwa ngepeyinti. Yakhwezwa kwindlu yokugcina impahla ngecrane.

I-27SiMn Steel Pipe = i-27 ye-silicon manganese ipayipi yensimbi, enye yezinto eziphathekayo zepayipi yensimbi engenamthungo, kunye nomxholo wekhabhoni uphakathi kwe-0.24-0.32%. I-SIMN idweliswe ngokwahlukileyo ngenxa yokuba umxholo we-silicon manganese kwizinto ezintlanu (i-carbon C, i-silicon Si, i-manganese Mn, i-phosphorus P, isulfure s) malunga ne-1.10-1.40%.

Umxholo: sele isebenza kwintsimi yombhobho wensimbi engenamthungo e-China iminyaka engaphezu kwe-20. Eli qela linemigca yokuvelisa umbhobho wentsimbi engaphezu kwe-10, ingakumbi ivelisa i-27SiMn ecinyiweyo kunye nombhobho wensimbi opholileyo, i-API series pipeline pipeline pipe, i-carbon steel round pipe kunye ne-American standard series pipe yentsimbi. Inoluhlu olubanzi lwezicelo. Ngoku abathengi bayo abaphambili bagxile eMzantsi Afrika, kuMbindi weAsia, eYurophu nakwamanye amazwe, kunye namawaka eetoni zesitokhwe ukubonelela ngemfuno yabathengi.
