ASTM A252 yog ib qho kev qhia tshwj xeeb rau welded thiab seamless steel yeeb nkab pawg tsim los ntawm American Society for Testing and Materials (ASTM), nrog rau kev hloov kho tshiab tshaj plaws hauv xyoo 2019. Cov qauv no siv rau cylindrical steel yeeb nkab piles siv los ua cov khoom ruaj khov -cov tswv cuab lossis cov pob zeb ua pob zeb, npog cov khoom tsim los ntawm ob qho tib si seamless welding.

A252 Pipe Loj
ASTM A252 steel yeeb nkab feem ntau yog siv rau hauv cov nram qab no:
Permanent Load-Cov Qauv Kabmob
Hla - hiav txwv / hla - tus choj choj pawg hauv paus (GR3 qib rau dynamic load kuj).
Super siab-nce tob tob (GR2 / GR3 qib rau ntsug load-cov kabmob muaj peev xwm).
Temporary Engineering
Foundation pit support piles (GR1 qib rau tus nqi-kev ua tau zoo).
Kev txhawb nqa ib ntus rau kev tsim kho platforms.
Ib puag ncig hnyav
Chaw nres nkoj terminals (yuav tsum tau epoxy / iav flake coatings rau ntsev corrosion kuj).
Offshore cua zog lub hauv paus (GR3 qib nrog kev sib xyaw los tiv thaiv-corrosion).
Kev Ntsuas Cov Lus Qhia rau seamless thiab welded A252 steel piling yeeb nkab
Kev Ntsuas Hydrostatic: Tsis tau teev tseg.
Mechanical Tests:
Tensile Test: Ob leeg longitudinal lossis transverse ntawm kev xaiv ntawm cov chaw tsim khoom.
Number of Tests: Ib qho kev ntsuas tensile ib 200 qhov ntev.
