ʻO ka hōʻoia ʻana o ka maikaʻi maoli o ka mea hana ʻo ST52 alloy steel pipe
Manaʻo ʻia ke kila kila ʻole e like me ke kila hoʻolālā maʻamau, ʻo ia ka mea i ʻike nui ʻia e ka ikaika tensile a me ka helu hua. Hoʻohana ʻia ia i ka hana kīwila, ka ʻenekinia lalo, ka hale alahaka, ka hale kai, ka hana ipu, kaʻa a me ka hana mīkini.
ʻO ka papa kila ka mea maʻamau i ka leka st, ke ʻano waiwai o ke kila a me ka helu helu maikaʻi. No ka laʻana, St52-3. No ka papa kila me kekahi mau koi koho no ke ʻano deoxidation, ua kau ʻia ka māka kūpono (U a i ʻole R) i mua o ka pae kila.
No ka laʻana: ust37-2 a i ʻole rst37-2
ʻO ka inoa liʻiliʻi st37-2 st37-3u st37-3n pani i 20 kila
He hōʻailona Kelemania ʻo St37, akā he hōʻailona maʻamau a me kekahi mau lama liʻiliʻi.
E like me st37-2, st37-3u, st37-3n, rst-2, ust37-2, etc.
ʻO St37-2 kahi hōʻailona o ke kila kalapona i Kelemānia
Ua like kēia mea me ke kila kila Q235B (helu inoa kahiko: a3-b) ma Kina
Eia kekahi, no ka mea, ua like kēia kila me ke kila kila kila 20 kiʻekiʻe o Kina, hiki ke hoʻololi ʻia e 20 kila.
ʻO ke kiʻekiʻe kiʻekiʻe seamless steel paipu a me ke kiʻekiʻe kaomi boiler paipu mea he 'ano o ka paila paipu, no ka waeʻano o seamless kila paipu. ʻO keʻano o ka hanaʻana ua like ia me ka paipuʻole, akā aia nā koi koʻikoʻi no ka pae kila i hoʻohanaʻia i ka hanaʻana i ka paipu kila. Hoʻohana pinepine ʻia nā paipu boiler kiʻekiʻe ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā kūlana kiʻekiʻe. Hoʻohana nui ʻia nā paipu paila kiʻekiʻe no ka hana ʻana i nā paipu superheater, nā paipu reheater, nā ʻea ea, nā pahu mahu nui, etc.
