Pono ka lōʻihi paʻa: e like me nā koi o ka mea hoʻohana.
Pololei: ≤1.5mm / m.
Ke kūlana hoʻouna a me ke kaʻina hana wela o ka paipu kila
Hāʻawi ʻia ka paipu kila ma ke kūlana wela maʻamau.
ʻO ke kaʻina hana mālama wela maʻamau o ka huahana i hoʻopau ʻia: 900 ° C ~ 930 ° C no 5 ~ 15min, hoʻoluʻu ea.
Nā waiwai mīkini o nā paipu kila
Nā waiwai tensile
ʻO nā waiwai tensile o nā paipu kila e hoʻokō i nā koi o ASTM A333Gr6.
No nā paipu kila me ka mānoanoa o ka paia ≤ 8mm, ʻo ka hōʻike hoʻāʻo tensile he hōʻailona hōʻike lōʻihi me ka laula o 12.5mm a me ka mamao ana o 50mm. No nā paipu kila me ka mānoanoa o ka paia ≥8mm, hiki ke hoʻohana ʻia kahi mea hoʻohālike poepoe me ka mamao ana o 4D.
Ho'āʻo palahalaha
ʻO 0.07 ka helu ʻana.
Ka hopena o ka hana
E nānā ʻia kēlā me kēia pūʻulu o nā paipu kila me ke anawaena o waho ma mua o 21.3mm no ka hopena Akv.

Ka wela ho'āʻo hopena
Ke piʻi a ʻoi aku ka mānoanoa o ka mea hoʻohālike liʻiliʻi i ka 80% o ka mānoanoa maoli o ka paipu kila, ʻo ka mahana hoʻāʻo ʻo -45 ° C.
Ke emi iho ka mānoanoa o ka mea hoʻohālike liʻiliʻi ma mua o 80% o ka mānoanoa maoli o ka paipu kila, pono e like ka nui o ka mānoanoa o ka specimen. ʻO ka mahana hoʻāʻo he -55 ° C.
ʻO ka ho'āʻo paʻakikī (inā koi ʻia e ka ʻaelike)
Inā makemake ka ʻaelike e hoʻāʻo ʻia ka paʻakikī e like me ka maʻamau NACE MR-0175, e lawe ʻia kahi ʻāpana hoʻāʻo ma kahi o 20-30 mm ka lōʻihi mai kēlā me kēia pūʻulu o nā paipu kila, a ʻo ka paʻakikī ma lalo o 22HRc.
