ʻO ka paipu API 5L X70 he mea hoʻoheheʻe maikaʻi loa i nā kikoʻī maʻamau API 5L. Ua kapa ʻia hoʻi ka paipu L485, no ka mea, ʻoi aku ka liʻiliʻi o ka ikaika 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 ʻana i ka aila a me ke kinoea.

Hoʻopau o ka API 5L X70 PSL2 Pipe
He laumania na welau o na paipu, me ke kaula ole.
Mai 60.3 anawaena beveled e like me nā kūlana:
DIN, EN – a = 40° – 60°, c = i 2 mm
ASME – a = 75° ± 5°, c = 1,6 ± 0,8 mm
Hoailona o API 5L X70 PSL2 Paipu a paipu puolo
Hōʻailona ʻia nā paipu me ke anawaena a hiki i ka 1 ½” me ka lepili ma ka pūʻolo. Hoʻokō ʻia nā paipu me ke anawaena nui aʻe ma mua o 1 ½” e like me nā kuhikuhi a i ʻole ke noi.
API 5L X70 PSL2 Pipe – pale ʻili
Hāʻawi ʻia nā paipu laina me ka pale ʻole ʻana i ka ʻino. Ma ke noi, hiki ke hoʻopuka i nā paipu me ka pale anticorrosion i ʻaelike ʻia. Hiki ke hoʻopaʻa ʻia nā ʻaoʻao o ka paipu e kahi pahu plastik.
