Hoʻopili ʻia ʻo API SPEC5CT (Casing and Tubing Specification) a paʻi ʻia e ka American Petroleum Institute (American Petreleum Institute, i kapa ʻia ʻo "API") a hoʻohana mau ʻia a puni ka honua.
I waena o lākou, casing: ʻo ka paipu e hoʻonui ana mai ka ʻili honua i loko o ka luawai e like me ka uhi ʻana o ka pā luawai, a ua hoʻopili ʻia nā paipu e nā kola. e like me C90 a me T95 i kū i ka hydrogen sulfide corrosion.
ʻO ka paipu aila: ʻO kahi paipu i hoʻokomo ʻia i loko o ka pahu mai ka ʻili o ka ʻāina a hiki i ka ʻaila ʻaila, a ua hoʻopili ʻia nā paipu e nā couplings a i ʻole integrally. ʻO nā mea nui he J55, N80, P110, a me nā māka kila e like me C90 a me T95. kū'ē i ka hydrogen sulfide corrosion.API SPEC 5L (Line Pipe Specification), i hōʻuluʻulu a paʻiʻia e ka American Petroleum Institute, ua hoʻohana mauʻia ma ka honua. a me ka ʻoihana kinoea ma o ka paipu laina.
Aia nā paipu laina i nā paipu wili ʻole a i hoʻopaʻa ʻia, a ʻo nā wēlau o ka paipu he mau wēlau palahalaha, nā wili wili a me nā kumu kumu;ʻO nāʻano hoʻohui ka hoʻopauʻana i ka welding, ka pilina kola, ka pilina socket, a me nā mea'ē aʻe.
ʻO nā blanks i hoʻohana ʻia no nā paipu kila welded ʻo nā papa kila a i ʻole ke kila kila.Ma muli o kā lākou mau mea like ʻole a me nā kaʻina hana, ua māhele ʻia nā paipu welded i nā paipu i hoʻopaʻa ʻia i ka umu, nā paipu wili uila (kuʻi kūʻē) paipu a me nā paipu arc welded. flat, etc.) welded pipe no nā kumu like ʻole, a ua māhele ʻia i nā ʻano like ʻole:
