Isingeniso somkhiqizo
I-ASTM A53 Grade B Seamless iwumkhiqizo wethu odume kakhulu ngaphansi kwalokhu kucaciswa futhi ipayipi le-A53 livamise ukuqinisekiswa okukabili ku-A106 B Ipayipi elingenamthungo.
I-ASTM A53 IBanga B iyinto engaphansi kwesilinganiso sepayipi lensimbi laseMelika, i-API 5L Gr.B iphinde ibe yimpahla ejwayelekile yaseMelika, i-A53 GR.B ERW isho ukumelana nogesi okushiselwe ipayipi lensimbi lika-A53 GR.B; I-API 5L GR.B Eshiselwe ibhekisela ezintweni ezishiselwe ipayipi lensimbi le-API 5L GR.B.

Ipayipi lensimbi elingenamthungo le-ASTM A53 wuphawu olujwayelekile lwaseMelika. I-A53-F ihambisana nokokusebenza kwe-Q235 yaseShayina, i-A53-A ihambisana nempahla yaseChina enguNombolo 10, futhi i-A53-B ihambisana nempahla yaseChina enguNombolo 20.
Inqubo yokukhiqiza
Inqubo yokukhiqiza ipayipi lensimbi engenamthungo ihlukaniswe yaba ipayipi elishisayo nelibandayo elingenamthungo.
1. Inqubo yokukhiqiza yepayipi yensimbi engenamthungo egoqelwe ngokushisayo: i-tube billet → ukushisa → ukubhobozwa → amarola amathathu/aginqaginqika ngokuqhubekayo → de-pipe → ukusika → ukupholisa → ukuqondisa → ukuhlolwa kwe-hydraulic → ukumaka → ipayipi lensimbi engenamthungo kutholwe umphumela wokuziphakamisa.
2. Inqubo yokukhiqiza yamashubhu ensimbi adonsa abandayo adonswa ngomthungo: ishubhu elingenalutho → ukushisisa → ukubhoboza → isihloko → i-annealing → pickling → ukugcoba amafutha → umdwebo obandayo obandayo → ishubhu elingenalutho → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa kwe-hydraulic → ukumaka → isitoreji.
Izinhlelo zokusebenza
1. Ukwakhiwa: ipayipi elingaphansi, amanzi angaphansi komhlaba, kanye nokuthuthwa kwamanzi ashisayo.
2. Ukucutshungulwa komshini, ukuthwala imikhono, ukucubungula izingxenye zemishini, njll.
3. Ugesi: Ukulethwa kwegesi, ipayipi loketshezi lwamandla kagesi
4. Amashubhu e-anti-static ezitshalo zamandla omoya, njll.
