Māhele 2 o nā kūlana kūpono no nā paipu ʻole

GB13296-2013 (Nā paipu kila ʻole no nā paila a me nā mea hoʻololi wela). Hoʻohana nui ʻia i nā boilers, superheaters, heat exchangers, condensers, catalytic tubes, etc. o nā ʻoihana kemika. Hoʻohana ʻia i ka wela kiʻekiʻe, kiʻekiʻe kiʻekiʻe, corrosion-resistant steel pipe. ʻO 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, etc. GB/T14975-1994 (Stainless steel seamless steel pipe for structure). Hoʻohana nui ʻia ia no ka hoʻolālā maʻamau (hōkele a me ka hale ʻaina hale ʻaina) a me ka hoʻolālā mechanical o nā ʻoihana kemika, e kū kūʻē i ka atmospheric a me ka acid corrosion a loaʻa kekahi mau paipu kila ikaika. ʻO kāna mau mea kikoʻī he 0-3Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, etc.

GB/T14976-2012 (Stainless steel seamless steel paipu no ka lawe wai). Hoʻohana nui ʻia no nā pipeline e lawe ana i ka media corrosive. ʻO nā mea ʻelele ʻo 0Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 0Cr18Ni12Mo2Ti, etc.

YB/T5035-2010 (Nā paipu kila ʻole no nā lima axle kaʻa). Hoʻohana nui ʻia ia e hana i ke kila kila kila kiʻekiʻe a me ke kila hoʻoheheʻe ʻia ʻana i nā paipu kila maʻemaʻe ʻole no nā kaʻa kaʻa hapalua axle lima a me nā paipu axle o nā hale axle hoʻokele. ʻO kāna mau mea kikoʻī he 45, 45Mn2, 40Cr, 20CrNi3A, etc.

API SPEC 5L-2018 (line pipe specification), i hōʻuluʻulu a hoʻopuka ʻia e ka American Petroleum Institute, hoʻohana mau ʻia ma ka honua holoʻokoʻa.

Paipu laina: loaʻa nā paipu ʻole a welded. ʻO nā wēlau paipu he mau wēlau palahalaha, nā welau wili a me nā kumu kumu; ʻO nā ala pili ka hoʻopau ʻana i ka welding, ka hoʻohui ʻana, ka pilina socket, etc. ʻO nā mea nui ʻo GR.B, X42, X52. X56, X65, X70 a me nā māka kila ʻē aʻe.

ʻO API SPEC5CT-2012 (Casing and Tubing Specification) i hōʻuluʻulu ʻia a hoʻopuka ʻia e ka American Petroleum Institute (American Petreleum Instiute, i kapa ʻia ʻo "API") a hoʻohana ʻia ma nā wahi āpau o ka honua.

i:

Casing: He paipu e hohola ana mai ka ʻili o ka honua a hiki i ka pūnāwai a lilo ia i mea hoʻopaʻa pā luawai. Hoʻopili ʻia nā paipu e nā hui. ʻO nā mea nui he mau kila kila e like me J55, N80, a me P110, a me nā māka kila e like me C90 a me T95 i kū i ka hydrogen sulfide corrosion. Hiki ke wiliwili ʻia kona pae kila haʻahaʻa (J55, N80).

Paipu: He paipu i hoʻokomo ʻia i loko o ka pahu mai ka ʻili honua a hiki i ka ʻaila ʻaila, a ua hoʻopili ʻia nā paipu e nā hui ʻana a i ʻole ka hui pū ʻana. ʻO kāna hana ʻo ia ka ʻae ʻana i ka ʻāpana pumping e lawe i ka ʻaila mai ka papa ʻaila a i ka lepo ma o ka paipu. ʻO nā mea nui he mau kila kila e like me J55, N80, P110, a me C90, T95 i kū i ka hydrogen sulfide corrosion. Hiki ke wiliwili ʻia kona pae kila haʻahaʻa (J55, N80).
