27SiMN Ipayipi Lepayipi Lensimbi Elicishiwe Futhi Elishisayo

Incazelo Yomkhiqizo

Ipayipi lensimbi ye-carbon steel noma ipayipi lensimbi yensimbi lenziwe ngensimbi yensimbi noma ipayipi eliqinile elingenalutho ngokusebenzisa ukubhobozwa, bese lenziwa ngokuginqika okushisayo, ukugoqa okubandayo noma umdwebo obandayo. Ipayipi lensimbi ye-Carbon lidlala indima ebalulekile embonini yamapayipi ensimbi yaseChina. Izinto ezisetshenziswayo zepayipi lensimbi ye-carbon yi-round tube blank. Ishubhu eliyindilinga elingenalutho liyasikwa futhi licutshungulwe ngomshini wokusika, futhi elingenalutho elinokukhula okungaba ngu-1m lithunyelwa esithandweni ukuze lishiswe ngebhande lokuthutha. I-billet ithunyelwa esithandweni ukuze kushiswe ekushiseni okungaba ngu-1200 degrees Celsius. Uphethiloli yi-hydrogen noma i-acetylene. Ukulawulwa kwezinga lokushisa esithandweni kuyinkinga eyinhloko. Ngemuva kokuthi i-tube billet eyindilinga ikhishwe esithandweni, kufanele ibhobozwe ngombhobho wokucindezela. Ngokuvamile, umbhobozi ovame kakhulu umbhobozi we-conical roll. Lesi sibhobosi sisebenza kahle kakhulu ekukhiqizeni, ikhwalithi yomkhiqizo omuhle, ukunwetshwa okukhulu kwezibhobo futhi singagqoka amamaki ensimbi ahlukahlukene. Ngemuva kokubhobozwa, ishubhu eliyindilinga elingenalutho ligoqwa ngokulandelana ngama-roll cross rolling, ukugoqa okuqhubekayo noma ukukhipha. Ngemuva kwe-extrusion, susa ipayipi ukuze ulinganise. Umshini wokulinganisa uzungezisa kumbungu wensimbi ngesivinini esikhulu ngokusebenzisa i-conical drill ukuze wakhe ipayipi lensimbi. Ububanzi bangaphakathi bepayipi lensimbi bunqunywa ubude be-diameter yangaphandle yebhithi yomshini wokulinganisa. Ngemva kokulinganisa, ipayipi lensimbi lingena embhoshongweni wokupholisa futhi lipholiswe ngesifutho samanzi. Ngemuva kokupholisa, ipayipi lensimbi lizoqondiswa. Ngemva kokuqondisa, ipayipi lensimbi lithunyelwa kumtshina wensimbi (noma ukuhlolwa kwe-hydrostatic) ngebhande lokudlulisa ukuze kutholwe amaphutha angaphakathi. Uma kukhona ukuqhekeka, ama-bubbles nezinye izinkinga ngaphakathi kwepayipi lensimbi, zizotholwa. Amapayipi ensimbi kufanele akhethwe ngokuqinile ngesandla ngemuva kokuhlolwa kwekhwalithi. Ngemuva kokuhlolwa kwepayipi lensimbi, inombolo, ukucaciswa, inombolo ye-batch yokukhiqiza, njll. izofafazwa ngopende. Futhi waphakanyiselwa endlini yokugcina izimpahla by crane.

27SiMn Steel Pipe = 27 silicon manganese steel pipe, okungenye yezinto zokwakha zepayipi lensimbi engenamthungo, futhi okuqukethwe kwekhabhoni kuphakathi kuka-0.24-0.32%. I-SIMN ibhalwe ngokwehlukana ngoba okuqukethwe kwe-silicon manganese ezakhini ezinhlanu (i-carbon C, i-silicon Si, i-manganese Mn, i-phosphorus P, isulfure s) icishe ibe ngu-1.10-1.40%.

Okuqukethwe: ibisebenza emkhakheni wepayipi lensimbi elingenamthungo e-China iminyaka engaphezu kwengu-20. Iqembu linemigqa yokukhiqiza yamapayipi ensimbi angenamthungo engaphezu kwe-10, ikakhulukazi akhiqiza ipayipi lensimbi elingu-27SiMn elicishiwe nelithambile, ipayipi lensimbi lepayipi le-API, ipayipi eliyindilinga le-carbon steel kanye nepayipi lensimbi elijwayelekile laseMelika. Inohlu olubanzi lwezinhlelo zokusebenza. Manje amakhasimende ayo ayinhloko agxile eNingizimu Afrika, e-Asia Ephakathi, e-Europe nakwamanye amazwe, nezinkulungwane zamathani esitokwe ukuhlinzeka ngesidingo samakhasimende.
