Uma kwenzeka iphutha elinjalo, kuzoba nomthelela omkhulu kumishini.I-oxide yensimbi inyibilika embobeni emise okwe-V.Uma unqenqema lomcu womshini wokushisela amapayipi kutholakala ukuthi ungaphansi kwezinga lokuncibilika, isivinini sokuncibilika sishesha kakhulu, ku-V. I-apex yomlomo, bese kuba umkhakha omncane oqukethe umagazini wensimbi encibilikisiwe, lezi ezincibilikisiwe. igolide I-Genus kanye nama-oxide ensimbi, ngokuvamile angakhishelwa ngemva kokukhishwa ngemva kokusetshenziswa okuvamile, akha ibhande lokufaka.I-weld ye-welder yepayipi izoqhekeka ngemva kokuchotshozwa, uma ukufakwa kutholakala endaweni ye-weld fracture.I-inclusions kanye nokuqhekeka kwe-fibrous weld kuyaqhathaniswa, futhi ukuphuka kuyisicaba kakhulu futhi akunayo i-metallic luster.Iziphambeko ezinjalo zingase futhi zinikeze uchungechunge lwama-"oxides" futhi alunasici kakhulu.

Ngaphansi kombhangqwana ojwayelekile, i-burr noma i-rust izowela ebhulohweni elakhiwe ngaphambi kwe-apex, okuzokwenza ukuthi ukujikeleza okufushane komshini wokushisela kubangele ukuthi i-current igxume.

I-Hebei Tubo Machinery Co., Ltd., ikhiqiza futhi ithunyelwe emazweni angaphezu kuka-30 womshini wepayipi wokushisela, umshini wamapayipi wokushisela,Umshini Wokwenza Amapayipi, Umshini Wethubhu, Umshini Wepayipi we-SS,Umshini Wamanzi Wasekhaya Wasekhaya, Umshini Wokwenza Ipayipi Lokwendlaleka Kwezolimo, Isaha Elibandayo, Umshini Wepayipi Eliyisikwele., kanye nemishini eyisiza iminyaka engaphezu kwengu-15.
I-TUBO Machinery, njengozakwethu wabasebenzisi, ayihlinzeki ngemikhiqizo yomshini enembayo kuphela, kodwa futhi nokusekelwa kobuchwepheshe yonke indawo nanoma nini.

Sisebenza ngomshini wokwenza amapayipi isikhathi esingaphezu kweminyaka eyi-15.
Singasiza ifektri yepayipi yensimbi ukuxazulula konke okunzima.
