API 5LʻO ka paipu kila maʻemaʻe he paipu kila maʻemaʻe no ka pipeline steel--API 5L paipu kila maʻemaʻeno ke kila paipu, ka paipu kila maʻemaʻe, ka mea hao paipu: GR.B, X42, X46, 52, X56, X60, X65, X70. Hoʻohana ʻia ka paipu paipu no ka lawe ʻana i ka aila, ke kinoea a me ka wai i unuhi ʻia mai ka lepo a i nā ʻoihana ʻenehana aila a me ke kinoea ma o nā paipu paipu. ʻO nā paipu paipu i loko o nā paipu liʻiliʻi a me nā paipu kila i hoʻopaʻa ʻia, a ʻo ko lākou mau wēlau paipu he mau wēlau palahalaha, nā wili wili a me nā kumu kumu; ʻO kā lākou mau ala pili ʻo ka welding, coupling connection, socket connection, etc.
API 5L pipeline kila, maʻamau: API5L ASTM ASME B36.10. DIN. ʻO ke anawaena o waho 13.7mm-1219.8mm, ka mānoanoa o ka paia 2.11mm-100mm.
Ka lōʻihi: 5.8m, 6m, 11.6m, 11.8m, 12m ka lōʻihi paʻa
Hoʻopili ʻia: paʻi kiʻi, bevel, pāpale paipu, puʻupuʻu kaula hao hao, kaula hāpai melemele, puʻupuʻu ʻeke piha.
1. Nā hiʻohiʻona o API 5LX42 paipu kila ʻole

API 5LX42ʻO ka paipu kila liʻiliʻi he ikaika kiʻekiʻe, haʻahaʻa haʻahaʻa haʻahaʻa me ka ikaika hua o 420MPa a me ka paʻakikī maikaʻi a me ka pale ʻana i ka corrosion. Hana ʻia ka paipu kila me ka hoʻohana ʻana i ke kaʻina hana ʻole, me ka paia o loko, ʻaʻole maʻalahi e hōʻiliʻili i ka lepo, a maʻalahi hoʻi e hoʻomaʻemaʻe a mālama. Eia hou, API 5LX42 seamless kila paipu no hoi i maikai weldability a me ke kū'ē i hydrogen-i hoʻokomoʻia pohā, hiki ke hoʻokō i nā koi hoʻohana i loko o koʻikoʻi kaiapuni.

2. Noi o API 5LX42 seamless kila paipu

API 5LX42 seamless kila paipu i hoʻohana nui 'ia i loko o ka aila a me ke kinoea pipelines, refineries, kemika mea kanu a me na mahinaai. Ma ke ʻano o ka lawe ʻana i ka aila a me ke kinoea, hiki i ka API 5LX42 mau paipu kila maʻemaʻe ke kū i nā kaiapuni koʻikoʻi e like me ke kiʻekiʻe kiʻekiʻe, ka wela kiʻekiʻe a me ka corrosion e hōʻoia i ka lawe ʻana i ka ʻaila a me ke kinoea. I loko o nā mea hoʻoheheʻe a me nā mea kanu kemika, hoʻohana ʻia nā paipu kila ʻole API 5LX42 no ka lawe ʻana i nā ʻano media corrosive, e like me ka sulfuric acid a me ka waika hydrochloric.

3. Ke kaʻina hana o API 5LX42 seamless kila paipu

ʻO ke kaʻina hana o ka API 5LX42 seamless steel pipes ka nui o ka hoʻomākaukau ʻana o ka tube blank preparation, perforation, rolling, heat treatment, straightening, inspection and packaging. Ma waena o lākou, ʻo ka hoʻomākaukau ʻana i ka tube blank kekahi o nā loulou kī, a pono e koho ʻia a nānā pono ʻia a mālama ʻia nā mea maka kiʻekiʻe. I ka wā o ka perforation a me ka ʻōwili ʻana, pono e mālama ʻia nā ʻāpana e like me ka mahana, ka wikiwiki a me ke kaomi e hōʻoia i ka mānoanoa o ka pā, ke anawaena a me ka maikaʻi o ka ʻili o ka paipu kila. Hoʻoponopono ka loulou mālama wela i nā ʻāpana e like me ka mahana wela, ka manawa insulation a me ka wikiwiki hoʻomaha e hiki ai i ka paipu kila ke loaʻa ka hoʻonohonoho maikaʻi a me ka hana. ʻO ka mea hope loa, pono e hoʻopaʻa ʻia ka paipu kila i ka nānā ʻana a me ka hoʻāʻo ʻana e hōʻoia i ka hoʻokō ʻana o kona maikaʻi i nā koi maʻamau.
