ʻO nā paipu laina Api 5l Papa B a i X70 Od Mai 219mm a i 3500mm

Wehewehe Pōkole:

ʻO kēia kikoʻī e hāʻawi i ke kūlana hana no ka ʻōnaehana paipu e lawe i ka wai, ke kinoea a me ka ʻaila i loko o nā ʻoihana aila a me ke kinoea kūlohelohe.

Aia ʻelua mau pae kikoʻī huahana, ʻo PSL 1 a me PSL 2, aia nā koi koi o PSL 2 no ke kūlike kalapona, ka notch toughness, ka ikaika hua kiʻekiʻe loa a me ka ikaika tensile.

Papa B, X42, X46, X52, X56, X60, X65, X70 a me X80.

Hoʻolako ʻo Cangzhou Spiral Steel pipes group co.,ltd i nā paipu SAWH e uhi ana i ka papa mai API B a i X70, ua loaʻa iā mākou ka palapala hōʻoia API 5L i nā makahiki ma mua a i kēia manawa ua hoʻohana nui ʻia kā mākou mau paipu laina e CNPC, CPECC no kā lākou mau papahana pipeline.

E kū pono ka paipu i ka hoʻāʻo hydrostatic me ka ʻole o ka leakage ma o ka weld seam a i ʻole ke kino paipu
ʻAʻole pono e hoʻāʻo ʻia nā mea hui ma ke ʻano hydrostatic, ke hoʻolako pono ʻia nā ʻāpana o ka paipu i hoʻohana ʻia i ka māka ʻana i nā mea hui ma mua o ka hana hoʻohui.
