Indlela Yokuvelisa
I-DIN 17175 St45.8 imibhobho yentsimbi engenamthungo inokuveliswa ngokuqengqeleka okushushu, ukuqengqeleka okubandayo, ukucinezela okushushu, umzobo oshushu okanye umzobo obandayo.
Imibhobho yentsimbi inokunyibilikiswa kwiziko elivulekileyo okanye kwiziko lombane ngokwendlela yokuvuthela kweoksijini, kwaye yonke intsimbi kufuneka iphoswe ngokwezibalo.
Ubukho
I-17175 St45.8 ipayipi yensimbi engenamthungo iya kuhanjiswa ngonyango olufanelekileyo lobushushu.Unyango lobushushu lubandakanya:
- Ukwenziwa kwesiqhelo.
-Ukuhlambalaza.
- Ukufudumala;ukusuka kubushushu bokucima, akubanda, kodwa kunomsindo.
- Lungisa ubunzima ngendlela yokuguqula isothermal.

Iphepha elincinci kufuneka lithathwe kwisiphelo esiphezulu somjikelezo ngamnye okanye i-square bar ingot yokuvavanya ukukhangela ukuba isiphelo esiphezulu sinqunywe ngokufanelekileyo.Uvavanyo lwe-Ultrasonic lunokwenziwa kwakhona kwi-shrinkage hole njengoko kukhethwe ngumthengisi.
Uvavanyo:
Uvavanyo lokuqinisekisa ukwakheka kweekhemikhali
uvavanyo lwe-hydrostatic
Uvavanyo lwe-tensile
Uvavanyo lwempembelelo ephawulweyo
Uvavanyo lwamandla esivuno
Uvavanyo lweringi
Uvavanyo olungonakalisi
I-Tube Flag
Zonke iipayipi zetsimbi ezifakwe ukuvavanya kunye nokwamkelwa ziya kuphawulwa kwicala lasekhohlo nasekunene lombhobho wokuphela kwe-300 mm.Inqaku lidla ngokuba linani.Iityhubhu ezinodonga olucekethekileyo zingasetyenziswa nangezinye iindlela.
Ukumakisha nokuodola
Ibakala lentsimbi okanye inombolo yezinto eziphathekayo kufuneka ibhalwe kwisifinyezo semveliso njengoko kubonisiwe kulo mzekelo ulandelayo:
Umzekelo 1:
I-DIN 17175 ububanzi obungaphandle 63mm, ubukhulu bodonga 2.5 mm ibakala lensimbi ST45.8, inombolo 1.03 0 5 umbhobho wentsimbi ongenamthungo ogama lakhe libhaliwe: umbhobho wentsimbi DIN 17175-ST45.8 - 63 × 2.5 okanye umbhobho wentsimbi DIN 17175 -1.03 – 63 × 2.5.
