Gxila kumehluko phakathi kwepayipi lensimbi elinembayo nepayipi lensimbi elingenamthungo ku-Shandong Steel Pipe Plant Precision steel pipe iwuhlobo lwempahla yepayipi yensimbi enemba kakhulu ngemva komdwebo obandayo noma ukugingqika okushisayo.Ngenxa yokuthi izindonga zangaphakathi nezangaphandle zepayipi lensimbi elinembile azinazo izingqimba ze-oxide, zimelana nokucindezela okuphezulu, akukho ukuvuza, ukunemba okuphezulu, i-gloss ephezulu, akukho ukuguqulwa ngenxa yokugoba okubandayo, akukho ukuvutha, akukho mifantu eyisicaba, njll. , zisetshenziselwa ikakhulukazi ukukhiqizwa kwezingxenye ze-pneumatic noma ze-hydraulic ezifana namasilinda noma I-cylinder ingaba nekhono noma i-welded.Ukwakheka kwamakhemikhali kwamashubhu ensimbi okunemba yi-carbon C, i-silicon Si, i-manganese Mn, isulfure S, i-phosphorus P, ne-chromium Cr.
Umehluko phakathi kokunemba kwepayipi lensimbi nepayipi lensimbi elingenamthungo
I-1, izici eziyinhloko zepayipi lensimbi engenamthungo ayikho i-welding seam, ingakwazi ukumelana nokucindezela okukhulu.Umkhiqizo ungaba ukuphonswa kanzima kakhulu noma ukudayela okubandayo.
2. Ipayipi yensimbi enembile ingumkhiqizo ovele eminyakeni yamuva.Ikakhulukazi inokubekezelelana okuqinile kanye nobulukhuni embobeni yangaphakathi kanye nobukhulu bodonga lwangaphandle.
Ulwazi lwamapayipi ensimbi luhlinzekwa yi-Shandong Seamless Steel Tube Factory.
