Inā makemake ʻoe e ʻike i ka ʻike hou aku, e like me ka ʻōlelo kūʻai, nā huahana, nā hoʻonā, a me nā mea ʻē aʻe, phoʻolimalimae leka uila mai iā mākou ma ka pūnaewele.
He mea kūʻai waiwai ʻo Tianjin Sanon Steel Pipe Co., Ltd. Aia kā mākou hale hana ma ke kūlanakauhale ʻo Cangzhou, ma ka moku ʻo Hebei. ʻO kā mākou kumu waiwai nuinā paipu paila, a ʻo nā mea i koho ʻiaASTM A335 P5/P11/P91/P92,ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. ʻO nā mea hana i koho ʻia no nā paipu paipu ʻo iaAPI 5L,API 5CT, nā mea hana i koho ʻia no nā paipu haki ʻailaGB/T 9948he 15MoG/12CrMoVG. Hōʻike ʻo GB/T 6479-2013 i nā mea 10#/20#, nā paipu hoʻololi wela SA179/SA210/SA192, a pēlā aku, nā paipu mīkini GB/T 8162 i nā mea 10#/20#/Q345/42CrMo, EN10210 i nā mea S355JOH/S355J2H, nā paipu pahu kinoea GB1 8248, i nā mea 34CrMo4/30CrMo.
ʻO ka mua, ka ʻaila a me ke kinoea. ʻO kēia ka mākeke nui loa no nā paipu kila seamless. ʻO ke kūlana maʻamau no ka casing, tubing a me ka paipu wili i hoʻohana ʻia ma ka puka uka.API 5CT, a ua komo pū nā mea hanaJ55, K55, L80a me P110. Nā paipu paipu no nā paipu mamao loa ma lalo, maʻamauAPI 5L, mea hanaX42 to X80I ka makahiki 2025, ʻo ka hapa o nā paipu kila humuhumu a Kina e hoʻokuʻu aku i ka Hikina Waena he 42%, a ʻo ia ka hapa nui.
ʻO ka lua, nā mea kanu hoʻomaʻemaʻe a me nā kemika a me nā kikowaena mana. ʻO nā paipu kila kila a me nā paipu kila alloy no ka hoʻomaʻemaʻe a me nā mea kanu kemika, nā paipu paila kiʻekiʻe no nā paila kikowaena mana, e like me P91 a me P92. Nā kūlana maʻamau: GB 5310,ASTM A335, ASTM A213Mea Hana: 15CrMoG, 12Cr1MoVG, a meP11, P22, P91, P92ʻOiai ʻo ka mākeke ʻEulopa wale nō ka mea e hoʻokuʻu aku ai i nā paipu humuhumu ʻole, he nui o lākou he mau huahana waiwai nui i hoʻohui ʻia.
ʻO ke kolu, kuhikuhipuʻuone, nā hana kūlanakauhale, a me nā alanui a me nā alahaka. Nui ka makemake no nā paipu i hoʻopaʻa ʻia ma kēia kahua. Nā kūlana maʻamau: GB/T 3091, ASTM A53, EN 10219. ʻO nā mea nui he kila kalapona Q235B a me Q355B. Loaʻa i nā ʻāina ma ka Belt and Road Initiative kahi koi nui no nā ʻoihana, a ua piʻi nui ka hoʻokuʻu aku i nā paipu i hoʻopaʻa ʻia i nā makahiki i hala iho nei.
ʻO ka hā, ka hana ʻana i nā mīkini. Hoʻohana ʻia nā paipu humuhumu kikoʻī kiʻekiʻe i huki anu ʻia i loko o nā pahu cylinder hydraulic, nā ʻau hoʻokele a me nā mea hoʻokuʻu haʻalulu. Nā Kūlana: GB/T 3639, EN 10305-1, ASTM A519. Mea Hana: 20#, 45#, 40Cr, 35CrMo. Eia kekahi, ke ulu nei ka ʻāpana ikehu hou: nā hale kiaʻi makani, nā brackets photovoltaic, a me nā cylinders kinoea hydrogen e hoʻohana ana i nā paipu kila.
ʻO nā kiko i luna aʻe nā wahi nui e hele ai no nā paipu kila e hoʻokuʻu aku i ka mākeke honua. Ma ka puke aʻe, e kaʻana like wau me ʻoukou i nā kikowaena honua nui no kēlā me kēia noi, e hoʻonohonoho ana i kahi kuhikuhi maopopo no kā mākou kālepa paipu kila ma waho.
