ASTM A252Yog tus qauv kev cai lij choj tsim los ntawm tusAmerican Society rau Kev Ntsuam Xyuas thiab Khoom (ASTM)RauWelded thiab Seamless Steel Yeeb Nkab pilesCov. Nws siv rauHlau Cylindrical Yeeb NkabSiv raws liMus tas li thauj khoom - cov kabmob qauv tawLos yogshells rau cam khwb cia - hauv - qhov chaw pob zeb piles.
Cov txheej txheem no feem ntau siv nyob rau hauvLub Hauv Paus TsimRauVaj tse, txuas hniav, thiab lwm yam qauv, Muab kev txhawb nqa ruaj khov rau cov kev tsim qauv no.

Kev Tshuaj Ntsuam Kev Xeem rau Seamless thiab Welded A252 Hlau Piling Yeeb Nkab
(1) Kev kuaj hydrostatic hydrostatic: tsis tau teev tseg.
(2) Kev Ntsuam Xyuas Cov Neeg Kho Mob: Tensile Kuaj: Tog ntev los yog transverse ntawm xaiv cov chaw tsim khoom.
(3) Tus naj npawb ntawm cov kev ntsuam xyuas: ib lub tensile xeem ib 200 ntev.
