Lub cylindricalASTM A252 Yeebyog siv rau piling tog twg los nyob rau hauv daim ntawv ntawm lub plhaub rau ib tug cam khwb cia pawg los yog nws yuav coj li ib tug mus tas li tswv cuab uas nqa ib tug load nyob rau hauv daim ntawv thov. Lub nominal phab ntsa ntawm lub cylindrical steel piling yeeb nkab yog enveloped los ntawm no specification.
Kev faib tawm ntawmA252 Hlau Piping Pipesyog mus rau hauv peb qib kawm, nrog rau txhua qhov kev nthuav qhia qib sib txawv sib txuas ua ke txuas ntxiv thiab kom muaj zog. Ob lub zog no yog pom tias muaj feem rau kev tsav tsheb. Thaum cov yeeb nkab rau qib 1 muaj qhov qis tshaj tawm thiab tensile lub zog tseem ceeb, cov khoom siv mechanical ntawmASTM A252 Qib 3 Hlau Kab Yeeb Nkabsupersede rau lwm cov qib. Lub zog tensile ntawm qeb 3 puag ncig txog 456 mpa thiab cov txiaj ntsig muaj txiaj ntsig ntawm 310 MPA. Qhov txiaj ntsig ntawm kev siv cov kav dej no yog tias lawv tuaj yeem raug txiav ua kom haum kom haum rau cov ntawv thov tshwj xeeb, uas hloov mus minimizes tus nqi. Txij li thaum lubASTM A252 Qib 2 Yeeb Nkabyog ruaj khov thiab ruaj khov, cov lag luam uas siv lawv tsis tas yuav nqis peev ntxiv rau cov peev txheej kom ruaj ntseg ntxiv rau kev txhawb nqa kev tsim kho. Tsis tas li ntawd, tus nqi qis ntawm lawv cov teeb tsa, nrog rau kev yooj yim hauv kev teeb tsa, ua rau lawv ua lag luam txaus nyiam. CovASTM A252 Yeeb Nkab Hlautuaj yeem kuaj xyuas thiab lawv qhov kev nyab xeeb tuaj yeem kuaj ua ntej kev teeb tsa.
