Medium a me ka haʻahaʻa kaomi kila paipu i hana ʻia ma Kina
(1) Gb3087-82 mau paipu kila maʻemaʻe no nā paila haʻahaʻa haʻahaʻa. E hoʻokō ka hoʻāʻo tensile me GB / t228-87, ka hoʻāʻo hydrostatic me GB / t241-90, ka hoʻāʻo ʻana me GB / t246-97, ka hoʻāʻo flaring me GB / t242-97 a me ka hoʻāʻo ʻana i ke anu me ka gb244-97.
(2) Gb5310-95 mau paipu kila maʻemaʻe ʻole no nā paila kiʻekiʻe. ʻO ka hoʻāʻo tensile, ka hoʻāʻo hydraulic a me ka hoʻāʻo palahalaha e like me nā mea i kuhikuhi ʻia ma gb3087-82; ʻO ka hōʻike hopena e like me ka gb229-94, ka hoʻāʻo flaring e like me GB / t242-97 a me ka hōʻike ʻana i ka nui o ka palaoa e like me Yb / t5148-93; Pono ka nānā ʻana i ka microstructure me gb13298-91, ʻo ka nānā ʻana o ka papa decarburized e like me ka gb224-87, a me ka nānā ʻana i ka ultrasonic e like me GB / t5777-96.
(3) E hoʻokō ʻia ka nānā ʻana i ka hana kino a me nā kuhikuhi o nā paipu paila i lawe ʻia e like me nā kūlana kūpono i ʻōlelo ʻia ma ka ʻaelike（ 1) ʻO nā ʻāina nui e lawe mai ana i nā paipu boiler ʻo Iapana a me Kelemānia. ʻO nā kikoʻī o nā huahana i lawe pinepine ʻia ʻo 15914.2mm; 2734.0mm; 219.110.0mm; 41975mm; 406.460mm, etc. ʻO ka palena iki he 31.84.5mm, a ʻo ka lōʻihi he 5 ~ 8m.
(2) Ma ka hihia koi hoʻokomo, ua ʻike ʻia he mau hemahema i loko o ka ST45 seamless boiler tubes i lawe ʻia mai Mannesmann steel pipe plant ma Germany i nā hemahema o loko ma mua o nā kānāwai o ka mea kanu a me nā kūlana o ka hui hao a me ke kila Kelemania.
(3) ʻO 34CrMo4 a me 12CrMoV nā paipu kila i lawe ʻia mai Kelemania. ʻO kēia ʻano paipu kila maikaʻi ka hana wela kiʻekiʻe a hoʻohana pinepine ʻia e like me ka paipu kila no ka paila wela kiʻekiʻe.
(4) Nui nā paipu hao i lawe ʻia mai Iapana, me nā kikoʻī o 426.012mm 5 ~ 8m; 152.48.0mm12m; 89.110.0mm6m; 101.610.0mm12m; 114.38.0mm6m; 127.08.0mm9m, etc. E hoʻokō i ka maʻamau ʻoihana Iapana jisg3458, a ʻo ka pae kila he stpa25. Hoʻohana pinepine ʻia kēia ʻano paipu kila e like me ke kākoʻo o ka paipu superalloy. ʻO ke kiʻekiʻe ke kiʻekiʻe o ka paipu kila maʻemaʻe ʻole he ʻano paipu ʻole. 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. Wahi a ka wela o ka lawelawe, ua māhele ʻia ia i loko o ka paila paila maʻamau a me ka paipu paila kiʻekiʻe.
① ʻO ka mahana lawelawe o ka paipu kila maʻemaʻe kiʻekiʻe ma lalo o 450 ℃, a ʻo ka paipu hale i hana nui ʻia me ka No. 10 a me ka No.
② ʻO ke kiʻekiʻe kiʻekiʻe seamless steel paipu pinepine i ka wela kiʻekiʻe a me ke kūlana kiʻekiʻe. E oxidized a corroded ka paipu ma lalo o ka hana o ke kinoea a me ka mahu. Pono ka paipu kila e loaʻa ka ikaika mau loa, ka anti-oxidation kiʻekiʻe a me ka hana corrosion a me ka paʻa paʻa maikaʻi.
