Izinga lokushisa eligoqiwe lomugqa ogoqiwe oshisayo
Ukushintsha kwezinga lokushisa eligoqiwe kungenza umugqa wensimbi ogoqiwe oshise uhlanganise usayizi wokusanhlamvu, inani le-deposition kanye nokushintsha kwe-morphology, kuyenze ishintshe izici zokukhanda.Ukushisa kokuqeda ukugoqa kufanele, kukhuphule izinga lokushisa lokugoqa, kubangela okusanhlamvu okwenziwe kabusha kube kukhulu, um...Funda kabanzi -
Izinzuzo ze-Summerged Arc Welding Spiral Steel Pipe
Kuvunguza inqubo yokukhiqiza ipayipi kanye nokusetshenziswa, kukhona yasungulwa eziningi Welding ezinhle kakhulu kanye nezindlela zokukhiqiza, kube nomthelela omkhulu ekuthuthukisweni ezinzile futhi ngokushesha imboni, kodwa futhi kwenza le mboni iye elungiselelwe ekuthuthukisweni.Iyiphi i-arc welding engaphansi kwamanzi eyi-wel...Funda kabanzi -
Ipayipi elivumelanayo elihlanganisiwe lokulethwa kwengcindezi ephezulu
Ipayipi lokulethwa kwe-Flexible high-pressure liyinto eyinhlanganisela eyenziwe nge-polymer enamandla athile aphezulu, ingcindezi ephezulu, ukugqwala, ukumelana ne-fouling, i-coefficient ye-friction, ukwahlukanisa okuhle, ukuguquguquka okuhle nempilo ende yepayipi lezimboni ze-petroleum.Inhlanganisela ephezulu eguqukayo...Funda kabanzi -
Izici zokumelana nokushisela amapayipi ensimbi (ERW steel pipe)
Ipayipi lensimbi le-ERW (Electric Resistance Welding) libizwa ngepayipi le-ERW noma ipayipi elishiselwe i-HF, linezinzuzo eziningi njengokulandelayo: 1) ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi, intengo yalo imayelana ne-UOE seam eqondile engaphansi kwe-arc welded steel, 85 %;2) ukunemba okuphezulu kwe-dimensional, ukujikeleza kwayo (Umjikelezo...Funda kabanzi -
Inqubo yepayipi lensimbi engenamthungo
Lenziwa kanjani ipayipi lensimbi elingenamthungo?Amapayipi ensimbi angenamthungo enziwa ngokufudumeza ingot eqinile nokusunduza induku yokubhoboza ukuze akhe ishubhu elingenalutho.Ukuqedwa kwensimbi engenamthungo kungenziwa ngamasu anjengokugoqwa okushisayo, ukudonswa okubandayo, ukuphenduka, ukugoqwa kwe-roto njll. Ngemva kokuqeda...Funda kabanzi -
Indlela yokuqeda isakhiwo esinebhande
Inhlangano yensimbi ephansi-carbon at lokushisa ekamelweni deformation of ferrite kanye pearlite, uma kukhona band isakhiwo ferrite kanye pearlite kushintshana imivimbo inhlangano.Isakhiwo sebhendi yepayipi lensimbi engenamthungo ephansi ye-carbon steel, ukusuka kumazinga okushisa asekamelweni kuya ekushiseni okujwayelekile, lapho izinga lokushisa nge-Ac1...Funda kabanzi
