Imibhobho edityanisiweyo yobude
Iimveliso Intshayelelo
Imibhobho yentsimbi edityanisiweyo yeLongitudinal ngokuqhelekileyo ihlelwa ngokusekelwe kwizinto ezenziwe ngazo, ukusetyenziswa kwazo okujoliswe kuzo, kunye nemigangatho ababambelela kuyo. Ngokuqhelekileyo, i-longitudinal welded steel pipes ezibhekiselele kwimigangatho eqhelekileyo kunye nokuhlelwa kweMibhobho yentsimbi ye-Submerged-Arc Welded Steel.
Imigangatho yezinto eziphathekayo:
Imibhobho yentsimbi edityanisiweyo yeLongitudinal ingahlelwa ngokusekelwe kwizinto ezenziwe ngazo, ezifana ne-carbon steel, insimbi engenasici, i-alloy steel, njl njl. Uhlobo ngalunye lwezinto eziphathekayo kunye nemigangatho yalo kunye neenkcukacha.
Imigangatho yokwenziwa kwemveliso:
Inkqubo yokuvelisa i-Summerged-Arc Welded Steel Pipes inokulandela imigangatho ethile ebekwe yimibutho efana ne-American Petroleum Institute (API), i-American Society for Testing and Materials (ASTM), okanye eminye imibutho yemigangatho yelizwe okanye yamazwe ngamazwe ngolu hlobo lulandelayo: API. 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711,EN10217, EN10219

Uvavanyo: Uhlalutyo lwecandelo leMichiza, iiPropati zoomatshini (amandla okugqibela okuqina, amandla emveliso, ukukhulisa), iiMpahla zobuGcisa (Uvavanyo oluthe tyaba, uvavanyo lokugoba, uvavanyo lweBlow, uvavanyo lweMpembelelo), ukuhlolwa kobungakanani bangaphandle, uvavanyo lwe-Hydrostatic, uvavanyo lwe-X-ray.
Isatifikethi soVavanyo lweMill: EN 10204/3.1B
Iikhrayitheriya zeSicelo: Imibhobho edityanisiweyo ye-Longitudinal nayo ingahlelwa ngokusekelwe ekusetyenzisweni kwayo okujoliswe kuyo, njengemibhobho yeoli kunye negesi, ukusetyenziswa kwezakhiwo, okanye ukusetyenziswa ngokubanzi kwimizi-mveliso. Qiniseka ukuba ubhekisa kwimigangatho ethile kunye nokuhlelwa okufanelekileyo kwiimfuno zakho ezithile, njengoko zinokwahluka ngokusekwe kushishino kunye nommandla.
