Cold Ford A252 Grade 1 Welded Steel Pipe For Structural Gasi Mapaipi
ASTM A252 ndi chitoliro chachitsulo chokhazikitsidwa bwino chomwe chimagwiritsidwa ntchito popanga milu ya maziko, milu ya mlatho, milu ya pier ndi magawo ena aumisiri.Mipope yachitsuloyi imapangidwa kuti ikhale yolimba kwambiri ndipo ndi yoyenera kugwiritsidwa ntchito m'malo osiyanasiyana ovuta.Zathuozizira anapanga welded structuralmapaipi a gasi amapangidwa kuchokera kuchitsulo cha A252 Grade 1, chomwe chimadziwika chifukwa cha kukhalitsa kwake komanso mphamvu zake.
Mechanical Property
| Gulu 1 | Gulu 2 | Gulu 3 | |
| Yield Point or yield strength, min, Mpa(PSI) | 205 (30 000) | 240 (35 000) | 310 (45 000) |
| Tensile mphamvu, min, Mpa (PSI) | 345 (50 000) | 415 (60 000) | 455 (66 0000) |
Ntchito yathu yomanga chubu yachitsulo imagwiritsa ntchito njira yowotcherera ya arc yomizidwa kawiri, kuwonetsetsa kuti zinthu zonse zili zolondola komanso zapamwamba.Njira imeneyi imaphatikizapo kuwotcherera mapaipi achitsulo kuchokera mkati ndi kunja, kupanga chomangira cholimba.Chotsatira chake ndi chinthu chomwe chimakhala chosawonongeka kwambiri komanso choyenera pa ntchito zosiyanasiyana za mafakitale ndi zomangamanga.
Chitoliro chathu cha gasi chozizira chopangidwa ndi mpweya chimapangidwanso kuti chikwaniritse zofunikira zamakina zomwe zafotokozedwa muyeso ya ASTM A252.Malinga ndi muyezo uwu, chitoliro chathu chachitsulo chimagawidwa m'magulu atatu: Grade 1, Grade 2 ndi Grade 3, ndipo giredi lililonse limapereka magawo osiyanasiyana amphamvu ndi kulimba.Izi zimathandiza makasitomala athu kusankha giredi yomwe ikugwirizana bwino ndi zomwe akufuna komanso momwe amagwirira ntchito.
Kaya amagwiritsidwa ntchito ngati milu ya maziko a ntchito yomanga kapena ngati mbali ya mlatho kapena pier pilings, mapaipi athu achitsulo amamangidwa kuti athe kupirira zovuta kwambiri.Amapereka magwiridwe antchito odalirika komanso kukhazikika kwanthawi yayitali, kuwapangitsa kukhala abwino kwa mitundu yosiyanasiyana ya uinjiniya ndi zomangamanga.
Mwachidule, wathu ozizira anapanga welded structuralmapaipi gasi, opangidwa kuchokera ku A252 Grade 1 zitsulo ndipo amapangidwa pogwiritsa ntchito njira yowotcherera ya arc yomwe ili pansi pa madzi, ndi njira yodalirika komanso yapamwamba yothetsera ntchito zosiyanasiyana.Mapaipi achitsulo awa amatsatira miyezo ya ASTM A252 ndipo amapangidwa kuti akwaniritse zofunikira zamakina, kuwonetsetsa kuti amapereka magwiridwe antchito apamwamba komanso olimba.Sankhani chitoliro chathu chachitsulo cha polojekiti yanu yotsatira ndikuwona kusiyana kwaubwino ndi kudalirika.
