He paipu kila wili ʻole ia e pono e hoʻokō i nā koi kemika a me nā waiwai mechanical o ka Papa B o API 5L, ASTM A106, a me ASTM A53 i ka manawa like.
Hiki ke hoʻohana maʻalahi ʻia kēia ʻano paipu i nā papahana like ʻole me ka hopohopo ʻole e pili ana i nā pilikia kūlike maʻamau. Hoʻomaʻalahi pū ia i ka hoʻokele waihona ma ka hōʻemi ʻana i ka pono e kūʻai i nā paipu o nā kūlana like ʻole.
Nānā: He mea nui e hoʻomaopopo ʻia ʻo API 5L GR.B ma ʻaneʻi e pili ana i ka API 5L PSL1 papa B.
Botop Steelhe mea hana paipu kila alakaʻi a me ka mea kūʻai aku ma Kina, loea i ka hana ʻana a me ka hoʻolako ʻana i ka paipu kila kalapona poepoe no nā noi wai a me ka aila. Mai ko mākou hoʻokumu ʻana i ka makahiki 2014, ua hoʻokuʻu ʻia aku kā mākou huahana i nā ʻāina a me nā wahi he nui e like me Australia, Kanada, India, Saudi Arabia, a pēlā aku, a ua hōʻiliʻili mākou i ka ʻike waiwai i ke kālepa honua.
Hana mākou i nā paipu kila me 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 a maʻamau. Uhi ka laina huahana i nā paipu kila humuhumu me nā anawaena waho mai 10.3 - 660 mm a me nā mānoanoa mai 2 - 100 mm.
Me ka ʻoi aku o 8,000 tone o nā paipu kila humuhumu i loko o ka waihona, hiki iā mākou ke hōʻoia i ka lawe koke ʻana o nā nui maʻamau. No nā ʻano a me nā nui kūikawā, hāʻawi pū mākou i nā lawelawe hana i hoʻopilikino ʻia e hoʻokō i nā koi kikoʻī o ka mea kūʻai aku.
Nā paipu kila humuhumu ʻolehana ʻia ma ʻelua mau kaʻina hana nui: hoʻopau wela a me ke kaha kiʻi anu.
Hiki i ka DN ≤ 40 ke hana i ka huki wela a i ʻole ke anu, ʻo ka hapa nui i huki anu ʻia.
Pono ka DN ≥ 50 e hoʻopau wela ʻia. Loaʻa pū nā paipu kila humuhumu anu ma ke noi.

I mea e hōʻoia ai ua hoʻokō ka paipu i nā koi hoʻohuihui kemika o ka Papa B o nā kūlana ʻekolu, ʻo API 5L, ASTM A106, a me ASTM A53, pono e kāohi pono ʻia ke ʻano kemika o ka mea i ka wā o ke kaʻina hana. Eia nā koi kikoʻī no ke ʻano kemika o kēia mau kūlana ʻekolu:
API 5L Papa B Hoʻohuihui Kemika
ʻO ka hoʻohuihui kemika ASTM A106 Papa B
ʻO ka hoʻohuihui kemika ASTM A53 Papa B
| Hoʻāʻo | API 5L PSL1 Papa B | Papa B o ASTM A106 | Papa B o ASTM A53 | |
| Ka ikaika hoʻopuka, min | MPa [psi] | 245 [35,500] | 240 [35,000] | 240 [35,000] |

ʻO ka hoʻohālikelike ʻana i nā koi mechanical no ka Papa B ma API 5L, ASTM A106, a me ASTM A53 e hōʻike ana he like ko lākou mau koi no ka tensile a me ka ikaika yield. ʻO kēia kūlike ke kumu no ka hoʻololi ʻana o kēia mau kūlana a hōʻoia i ka hiki ke hoʻohana ʻia nā huahana tubular i nā ʻano noi like ʻole me ka hopohopo ʻole no nā waiwai kūpono ʻole.

Ma waho aʻe o ka hoʻolako ʻana i nā paipu kila humuhumu kiʻekiʻe,Botop Steelhāʻawi i kahi ākea o nā lawelawe uhi ʻili e hoʻokō i nā pono pale ʻino like ʻole a me nā kūlana kaiapuni.
Hoʻokaʻawale pinepine ʻia nā uhi paipu kila i ka pale manawa pōkole a me ka pale ʻana i ka palaho lōʻihi. ʻIke pinepine mākou i ka paipu kila humuhumu i uhi ʻia me kahi uhi ʻeleʻele, i hoʻohana ʻia e hāʻawi i ka pale manawa pōkole e hōʻemi i ka palaho i ka wā o ka lawe ʻana i ke kai a me ka mālama ʻana i ka paipu.
