Flattening Test
Thaum qhov kev ncua deb ntawm ob daim hlau mus txog qhov kev ncua deb H, yuav tsum tsis muaj qhov tsis xws luag lossis tawg ntawm cov yeeb nkab steel.
Rau seamless steel raj: H = (1 + e) t / (e + t / D);
Rau ERW steel kav: H = 1/3 D (rau vuam) lossis H = 2/3 D (rau qhov tsis muaj vuam);
H: nrug nruab nrab ntawm flattening daim hlau (mm);

Flattening Test yog siv tau rau cov kav hlau uas muaj lub taub nominal siab dua 40A (48.6mm).
Kho tau
Bendability siv tau rau cov kav dej uas muaj lub taub nominal ntawm 40 A (48.6) lossis me dua.
Cov yeeb nkab yuav tsum tau khoov 90 ° ntawm lub vojvoog ntawm 6 npaug ntawm nws txoj kab uas hla.Cov phab ntsa yeeb nkab yuav tsum tsis muaj qhov tsis xws luag lossis tawg.
Txhua cov yeeb nkab steel yuav tsum tau ua qhov kev sim siab hydrostatic los yog tsis muaj kev puas tsuaj.
