Iqoqo lakamuva le-18 intshi SCH40ASTM A53 Grade B ERW amapayipi ensimbiuphumelele ngempumelelo ukuhlolwa okunzima okwenziwa ilabhorethri yomuntu wesithathu.
Phakathi nalokhu kuhlola, senze izivivinyo ezimbalwa ezibalulekile zokusebenza kwemishini ukuze siqinisekise amandla nokuthembeka kwamapayipi ensimbi e-ASTM A53 Grade B ERW. Ngezansi kunamavidiyo aqoshiwe achaza izidingo nezinqubo zokuhlolwa kokucaba kanye nokuhlolwa okuqinile.
Ukuhlolwa kwe-flattening kuhlukaniswe ngezinyathelo ezintathu zokuhlola ukumelana okuphansi kwezikhundla ezihlukene zepayipi lensimbi.
1. Isinyathelo sokuqala: Lokhu ukuhlolwa kwe-ductility ye-weld. Akukho ukuqhekeka noma ukuphuka okuzoba khona ngaphakathi noma ngaphandle kwendawo ye-weld ngaphambi kokuba ibanga phakathi kwamapuleti lincishiswe libe ngaphansi kwezingxenye ezimbili kwezintathu zobubanzi obushiwo bangaphandle bepayipi.
2. Esinyathelweni sesibili, ukwenza isicaba kuzoqhubeka njengokuhlola i-ductility kude ne-weld. Phakathi nalesi sinyathelo, akukho mifantu noma ukuphuka okuyoba khona endaweni yangaphakathi noma yangaphandle kude ne-weld, ngaphambi kokuba ibanga phakathi kwamapuleti lincishiswe libe ngaphansi kwengxenye eyodwa kwezintathu yobubanzi obushiwo obungaphandle bepayipi, kodwa kungabi ngaphansi kwezikhathi ezinhlanu ubukhulu bodonga olucacisiwe lwepayipi.
3. Phakathi nesinyathelo sesithathu, okuwukuhlolwa kokuzwakalayo, ukwenza isicaba kuzoqhutshekwa kuze kube yilapho isifanekiso sokuhlola siphuka noma kuhlangana izindonga eziphambene zesampula yokuhlola. Ubufakazi bempahla elamine noma engaphilile noma i-weld engaphelele evezwa ukuhlolwa kokucaba kuyoba yisizathu sokwenqatshwa.
Ividiyo engezansi ibonisa isinyathelo sesibili sokuhlolwa kokucaba.
Ukuhlolwa kwe-tensile kuwukuhlola okubalulekile kunqubo yokuhlola ipayipi lensimbi, elikwazi ukuhlola amandla aqinile kanye nokudumba kwepayipi. Kumapayipi ensimbi e-ASTM A53 Grade B ERW, amandla amancane adingekayo ama-MPa angama-415, kanti amandla amancane okukhiqiza ama-MPa angama-240.
Ngezansi ividiyo yokuhlola yokuhlolwa kwe-tensile:
Njengomphakeli wepayipi lensimbi ochwepheshe futhi onokwethenjelwa e-China,Insimbi ye-Botopuzibophezele ekuhlinzekeni amakhasimende ngemikhiqizo yamapayipi ensimbi esezingeni eliphezulu, engabizi, ukuqinisekisa ukuthi wonke amapayipi aphuma embonini yethu ahlangabezana nezindinganiso ezidingekayo.
Sicela uzizwe ukhululekile ukusithinta nganoma yisiphi isikhathi. I-Botop Steel izokujabulela ukukusebenzela.
