Intshayelelo yemveliso
I-ASTM A53 Grade B Engenamthungo yeyona mveliso yethu idumileyo phantsi kolu balulo kwaye umbhobho we-A53 ukholisa ukuqinisekiswa kabini ukuya kwi-A106 B yombhobho ongenamthungo.
I-ASTM A53 iBanga le-B yinto ephantsi komgangatho wombhobho wensimbi waseMelika, i-API 5L Gr.B nayo i-American standard material, i-A53 GR.B ERW ibhekisela kwi-electric resistance welded steel pipe ye-A53 GR.B; I-API 5L GR.B I-Welded ibhekisa kwizinto eziWelded steel pipe ye-API 5L GR.B.

I-ASTM A53 umbhobho wentsimbi ongenamthungo luphawu oluqhelekileyo lwaseMelika. I-A53-F ihambelana nezinto ze-Q235 zaseChina, i-A53-A ihambelana ne-China ye-10 yezinto eziphathekayo, kunye ne-A53-B ihambelana ne-China ye-20 yezinto eziphathekayo.
Inkqubo yokuvelisa
Inkqubo yokwenziwa kombhobho yentsimbi engenamthungo yahlulwe ibe ngumbhobho oshushu oqengqelekayo kunye obandayo ongenamthungo.
1. Inkqubo yokuvelisa umbhobho wentsimbi engenamthungo eqengqelekayo: ityhubhu billet → ukufudumeza → ukugqobhoza → ukuqengqeleka okuthathu/ukuqengqeleka nokuqengqeleka ngokuqhubekayo → ukukhupha umbhobho → ukupholisa → ukulungisa → uvavanyo lwehydraulic → ukumakisha → umbhobho wentsimbi ongenamthungo kunye nesiphumo sokuphakama sichongiwe.
2. Inkqubo yokuvelisa iityhubhu zentsimbi ezingenamthungo ezitsalwa ngokubanda: ityhubhu engenanto → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuqhola → ukufakwa kwe-oyile → umzobo obandayo ophindaphindiweyo → ityhubhu engenanto → unyango lobushushu → ukulungisa → uvavanyo lwehydraulic → ukumakisha → ukugcinwa.
Usetyenziso
1. Ukwakhiwa: umbhobho ongaphantsi, amanzi aphantsi komhlaba, kunye nothutho lwamanzi ashushu.
2. Ukucutshungulwa komatshini, ukuthwala imikhono, ukusetyenzwa koomatshini, njl.
3. Umbane: Ukuhanjiswa kwegesi, umbhobho wolwelo lwamandla ombane
4. Iityhubhu ze-Anti-static zezityalo zamandla omoya, njl.
