API 5L X70 laina seamless kila paipu

ʻO ka paipu API 5L X70 he mea hoʻoheheʻe maikaʻi loa i nā kikoʻī maʻamau API 5L. Ua kapa ʻia hoʻi ka paipu L485, ʻoiai ʻo ia ka ikaika e hāʻawi ai
ka palena iki ma 485 Mpa (70,300 psi). Hoʻopili ʻo API 5L X70 i nā ʻano hana i nā ʻano seamless a welded (RW, SAW), i hoʻohana ʻia.
no ka lawe ana i ka aila a me ke kinoea.

Hiki ke wehewehe ʻia ʻo API X70 carbon steel line pipe e like me ka paipu kila me ka ʻike kalapona kiʻekiʻe a me ka hui hoʻohuihui. API 5L X 70 carbon steel seamless paipu Ma waho aʻe o ka helu o nā mea ʻē aʻe e like me ka sulfur, phosphorus, a me nā mea ʻē aʻe, he kiʻekiʻe ka nui o ka manganese a me ke silikoni kona huila. ʻO ka hoʻohui ʻana o kēia mau mea āpau e kōkua i ka hoʻomaikaʻi ʻana i nā waiwai mechanical o ka paipu kila carbon X70.

Hiki ke ʻike ʻia kēia mai ka ikaika haʻahaʻa haʻahaʻa (485 MPa) o ka paipu API 5L X70 Class B LSAW. Loaʻa iā ia ka ikaika tensile liʻiliʻi o 635 MPa. Hoʻohana ʻia ka ʻili o nā paipu API 5L X70 SCH 40 DSAW i nā ʻano like ʻole, e like me ka ʻeleʻele, ka aila anticorrosive, ka wela wela a i ʻole ke anu-galvanized. Ma muli o ka hoʻohana kikoʻī ʻana o X70 PSL2 spiral tube, hiki iā mākou ke ʻōlelo aku i ka mālama ʻana i ka ʻili maikaʻi loa no kā mākou mea kūʻai. No ka laʻana, hōʻike ka pale galvanized ma nā paipu papa X70 PSL1 i ka pale ʻana i ka corrosion maikaʻi loa.
