He paipu kila maʻemaʻe ʻole ia e pono e hoʻokō i ka haku mele a me nā pono waiwai mechanical o ka Papa B o API 5L, ASTM A106, a me ASTM A53 i ka manawa like.
Hiki ke hoʻohana maʻalahi kēia ʻano paipu i nā papahana like ʻole me ka hopohopo ʻole e pili ana i nā pilikia hoʻohālikelike maʻamau.He mea maʻalahi hoʻi ia i ka hoʻokele waiwai ma ka hōʻemi ʻana i ka pono e kūʻai i nā paipu o nā kūlana like ʻole.
'Ōlelo Aʻo: He mea nui e hoʻomaopopo i ka API 5L GR.B maanei e pili ana i ka API 5L PSL1 papa B.
Ke kila BotopʻO ia ke alakaʻi nui o ka paipu kila a me ka mea kūʻai aku ma Kina, ʻoihana kūikawā i ka hana ʻana a me ka hoʻolako ʻana i ka paipu kila carbon seamless no ka wai a me ka aila.Mai ko mākou hoʻokumu ʻana i ka makahiki 2014, ua lawe ʻia kā mākou huahana i nā ʻāina a me nā ʻāina he nui e like me Australia, Canada, India, Saudi Arabia, a pēlā aku, a ua hōʻiliʻili mākou i ka ʻike waiwai ma ke kālepa honua.
Hana mākou i nā paipu kila ma ka hoʻokō pono ʻana i nā kūlana honua e like me API 5L, ASTM A106, a me ASTM A53 e hōʻoia i nā huahana kiʻekiʻe.Hoʻopili ka huahana i nā paipu kila ʻole me nā anawaena o waho mai 10.3 - 660 mm a me nā mānoanoa mai 2 - 100 mm.
Me ka nui o 8,000 tons o nā paipu kila maʻemaʻe i loko o ka waihona, hiki iā mākou ke hōʻoia i ka lawe koke ʻana i nā nui maʻamau.No nāʻano kūikawā a me nā nui, hāʻawi pū mākou i nā lawelawe hana hana maʻamau e hoʻokō i nā koi o ka mea kūʻai.
ʻO nā paipu kila ʻolehana ʻia i ʻelua kaʻina hana nui: ka hoʻopau wela a me ke kiʻi anu.
Hiki iā DN ≤ 40 ke hoʻopau i ka wela a i ʻole ka huki anu, ka nui o ke anu.
E wela ka DN ≥ 50.Loaʻa nō hoʻi nā paipu kila liʻiliʻi i huki ʻia i ke anu ma ke noi.
