Ukukhiqiza: Inqubo Engenazihibe.
Ubukhulu bangaphandle: 14mm-711mm.
Ubukhulu bezindonga: 2mm-60mm.
Ubude: Ubude obulungisiwe (6m, 9m, 12m, 24m) noma ubude obujwayelekile (5-12m).
Iphela: Iphansi, i-Beveled, inyathelwe.
Indlela Yokukhiqiza
I-DIN 17175 St45.8 amapayipi ensimbi angenamthungo angakhiqizwa ngokugoqeka okushisayo, ukugoqa okubandayo, ukucindezela okushisayo, ukudweba okushisayo noma umdwebo obandayo.
Amapayipi ensimbi angancibilikiswa eziko elivulekile noma eziko likagesi ngokwendlela yokuphefumula komoyampilo, futhi yonke insimbi kufanele iphonswe ngokwezibalo.
Ukutholakala
17175 St45.8 ipayipi lensimbi engenamthungo izolethwa ngokuphathwa kahle kokushisa.Ukwelashwa kokushisa kuhlanganisa:
- Normalization.
- Ukulinganisa.
- Ukushisa;kusukela ekushiseni okucishayo, akubandi, kodwa kuthukuthele.
- Lungisa isisindo ngendlela ye-isothermal transformation.

Ishidi elincanyana kufanele lithathwe ekugcineni okuphezulu kwengot ngayinye eyindilinga noma yesikwele ukuze kuhlolwe i-picling ukuze kunqunywe ukuthi ukuphela okuphezulu kusikwe ngokwanele yini.Ukuhlolwa kwe-Ultrasonic nakho kungenziwa embotsheni yokuncipha njengoba kukhethwe umphakeli.
Isivivinyo:
Ukuhlolwa kokuqinisekisa ukwakheka kwamakhemikhali
ukuhlolwa kwe-hydrostatic

Wonke amapayipi ensimbi athunyelwe ukuze ahlolwe futhi amukelwe azophawulwa emaceleni angakwesokunxele nangakwesokudla ekupheleni kwepayipi ngo-300 mm.Umaki ngokuvamile inombolo.Amashubhu anezindonga ezincane angasetshenziswa nangezinye izinhlobo.
Ukumaka noku-oda
Ibanga lensimbi noma inombolo yezinto ezibonakalayo kufanele ibhalwe kusifinyezo somkhiqizo njengoba kukhonjisiwe kulesi sibonelo esilandelayo:
