Iibka Kulul Dhexroorka ASTM A252 GR.B Spiral Welded Carbon Steel Pipe SSAW Pipe for Pile Foundation Works

Faa'iidooyinka dhuumaha alxanka leh ee wareegsan
(1) Waxaa suurtogal ah in la isticmaalo balac isku mid ah oo birta xariijimaha ah si loo soo saaro tuubooyinka birta ee dhexroorka kala duwan, iyo sidoo kale in la isticmaalo xariijimo dhuuban si loo soo saaro tuubooyinka birta ee waaweyn.
(2) Isla xaalad isku mid ah oo cadaadis ah, diiqada tollaynta welded ee wareega waxay ka yar tahay tan tolitaanka tooska ah ee tolitaanka, taas oo ah 75% ilaa 90% ee tuubada toosan ee tolnimada welded, sidaas darteed waxay u adkeysan kartaa cadaadis weyn. Marka la barbardhigo tolmo toosan oo alxanka leh dhexroorka weyn ee isku midka ah, dhumucda derbiga waxaa lagu dhimi karaa 10% ilaa 25% isla cadaadis isku mid ah.
(3) Saxnaanta cabbirka, dulqaadka dhexroorka oo aan ka badnayn 0.12%, leexashada in ka yar 12,000, ellipticity in ka yar 1%, guud ahaan waxay tirtirtaa habka cabbirka iyo toosinta.
(4) Wax soo saarka joogtada ah, aragti ahaan waxay soo saari kartaa tuubo birta dheer, madaxa yar iyo luminta dabada, isticmaalka birta waxaa lagu kordhin karaa 6% ilaa 8%.
