Nā kikoʻī o ka paipu kila humuhumu, nā kūlana a me ka papa.

Hoʻohana nui ʻia nā paipu kila humuhumu ʻole ma nā ʻoihana like ʻole no ka lawe ʻana i nā wai a me nā kinoea, a no nā noi kūkulu. Hana ʻia lākou me ka ʻole o ka wili ʻana a i ʻole nā ​​​​humuhumu, kahi e hoʻoikaika ai a hilinaʻi hoʻi. ʻO nā kikoʻī, nā kūlana, a me nā māka nonā paipu kila humuhumu ʻolehiki ke ʻokoʻa ma muli o nā koi kikoʻī o ka noi. Eia kekahi mau kikoʻī i hoʻohana pinepine ʻia, nā kūlana, a me nā māka no nā paipu kila seamless:

Kikoʻī:ASTM A106-Kōkuhi Kūlana no ka Paipu Kila Kalapona Seamless no ka lawelawe ʻana i ka mahana kiʻekiʻe

1. Uhi kēia kikoʻī i ka paipu kila kalapona humuhumu no nā noi wela kiʻekiʻe. Loaʻa iā ia nā papa like ʻole e like me A, B, a me C.

Kikoʻī:ASTM A53-Kōkuhi Kūlana no ka Paipu, Kila, ʻEleʻele a me ka Wela-Ipu, Uhi ʻia me ka Zinc, Welded a me ka Seamless

1. Uhi kēia kikoʻī i nā paipu kila galvanized ʻeleʻele a me ka wili ʻia i hoʻoluʻu ʻia a wela. Loaʻa iā ia nā ʻano papa like ʻole e like me A, B, a me C.

Kikoʻī:API 5L- Nā kikoʻī no ka paipu laina

1. Uhi kēia kikoʻī i ka paipu laina kila seamless a welded no nā noi like ʻole. Loaʻa iā ia nā papa like ʻole e like mePapa API 5L B, X42, X52, X60, X65, a pēlā aku.

wehewehe ʻana:ASTM A252-kuhikuhi i nā koi no nā paila paipu kila i hoʻopili ʻia a wili ʻole ʻia no ka hoʻohana ʻana i ke kūkulu ʻana a me nā noi kūkulu.

1. Uhi ka kikoʻī ASTM A252 i ʻekolu mau papa o nā paila paipu kila: Papa 1, Papa 2, a me Papa 3. Loaʻa i kēlā me kēia papa nā waiwai mechanical like ʻole, me ka ikaika hua liʻiliʻi a me ka ikaika tensile liʻiliʻi, e hoʻokō ai i nā koi papahana kikoʻī.
