Kiekie Kiekie Seamless Bright Tube
ʻO nā kaʻa, nā ʻāpana mīkini, a me nā mea ʻē aʻe he koi kiʻekiʻe i ka pololei a me ka hoʻopau ʻana o nā paipu kila.ʻO nā mea hoʻohana i nā paipu kila kūpono ʻaʻole wale nā mea hoʻohana i loaʻa nā koi kiʻekiʻe no ka pololei a me ka maʻalahi.No ka mea he kiʻekiʻe ka pololei o nā paipu ʻālohilohi a hiki ke mālama ʻia ka hoʻomanawanui ma nā uea 2--8, nui nā mea hoʻohana machining e mālama i ka hana, nā mea, a me ka manawa.Hoʻololi mālie ʻia nā paipu kila ʻole a i ʻole ke kila poepoe i mau paipu ʻālohilohi pololei.
ʻekahi:ʻIke ʻia ke anawaena o waho o ka paipu ʻālohilohi, kikoʻī, ka mānoanoa o ka paia e hiki ke hoʻopaʻa i ke ʻano helu helu kaomi (ʻokoʻa ka ikaika tensile o nā mea paipu kila like ʻole)
ʻO ke kaomi = (ka mānoanoa o ka paia * 2 * ka ikaika uʻi o ka paipu kila) / (ke anawaena o waho * koena)
ʻElua: ʻO ka paipu seamless i ʻike ʻia ke anawaena o waho o ka paipu kila maʻemaʻe a me ke ʻano helu o ka mānoanoa o ka paia ma lalo o ke kaomi.
ʻO ka mānoanoa o ka pā = (ka puʻe * anawaena o waho * koena) / (2 * ikaika tensile mea paipu kila)
ʻEkolu: ʻO ke ʻano o ka hōʻike ʻana i ka coefficient kaomi o ka paipu ʻālohilohi ʻole:
Pumi paipu kila P<7Mpa coefficient S=8
7
Pumi paipu kila P>17.5 coefficient S=4
