Hoʻokaʻawale a me nā mea o ka paipu kila carbon seamless

ʻO ka paipu hao kalapona ʻole he ʻano paipu i hoʻohana nui ʻia i ka ʻoihana ʻoihana. ʻAʻole pili kāna kaʻina hana i kekahi welding, no laila ka inoa "seamless". Hana ʻia kēia ʻano paipu me ke kila hoʻolālā kalapona kiʻekiʻe a i ʻole ke kila kila ma ka ʻōwili wela a i ʻole ke anu. Hoʻohana nui ʻia ka paipu kalapona kalapona ʻole ma nā ʻano he nui e like me ka aila, ke kinoea maoli, ka ʻoihana kemika, ka paila, ka ʻimi ʻāina a me ka hana mīkini ma muli o kona ʻano like ʻole a me ka ikaika, a me ke kūpaʻa maikaʻi a me ke kūpaʻa wela. No ka laʻana, hoʻohana nui ʻia nā paipu kila liʻiliʻi no nā paila haʻahaʻa a me ka haʻahaʻa no ka hana ʻana i nā paipu mahu superheated, nā paipu wai paila a me nā paipu mahu superheated no nā paila locomotive o nā ʻano paila haʻahaʻa a me waena. A hoʻohana ʻia nā paipu kila maʻemaʻe ʻole no nā paila kiʻekiʻe no ka hana ʻana i nā paipu no ka ʻili wela o nā paila wai me ke kaomi kiʻekiʻe a ma luna. Eia kekahi, hiki ke hoʻohana ʻia nā paipu kila kalapona maʻemaʻe e hana i nā ʻāpana a me nā ʻāpana mechanical, e like me nā kaʻa kaʻa kaʻa, nā kaʻa kaʻa, a me ka scaffolding kila i ke kūkulu ʻana. Ma muli o ke ʻano o kāna kaʻina hana, hiki i nā paipu kila carbon seamless ke kū i ka piʻi kiʻekiʻe i ka wā o ka hoʻohana ʻana a ʻaʻole kūpono i ka leakage, no laila he mea koʻikoʻi lākou i ka lawe ʻana i nā wai.

ʻO ka hoʻokaʻawale ʻana o nā paipu kila carbon seamless e pili ana i nā mea hana a me nā hoʻohana. E like me ke ʻano hana, hiki ke hoʻokaʻawale ʻia nā paipu kila carbon seamless i ʻelua mau ʻāpana: ʻōwili wela a me ke anuanu (huki). ʻO nā paipu kila maʻemaʻe ʻole i ʻōwili ʻia me nā paipu kila maʻamau, nā paipu kila haʻahaʻa a me ka haʻahaʻa haʻahaʻa, nā paipu kila hoʻoheheʻe kiʻekiʻe, nā paipu kila kila, nā paipu kila kila, nā paipu pohā ʻaila a me nā ʻano ʻano ʻē aʻe, ʻoiai ʻo ka ʻōwili anu (kau ʻia) ʻO nā paipu kila maʻemaʻe, ʻo ia nā paipu kila ʻeleʻele kalapona, nā paipu kila lahilahi, nā paipu kila lahilahi a me nā paipu kila kūikawā. Hōʻike pinepine ʻia nā kikoʻī o nā paipu kila ʻole i nā millimeters o ke anawaena o waho a me ka mānoanoa o ka pā. ʻO nā mea i loaʻa ke kila kila maʻamau a kiʻekiʻe (e like me Q215-A a i Q275-A a me 10 a 50 kila), ke kila kila haʻahaʻa (e like me 09MnV, 16Mn, a me nā mea ʻē aʻe), ke kila kila a me ke kila kila. . ʻO ke kohoʻana o kēia mau mea pili i ka ikaika, ka paʻi paʻi a me ka corrosion resistance o ka pipeline, no laila e loaʻa nā koi waiwai likeʻole i nāʻoihanaʻoihana likeʻole. No ka laʻana, hoʻohana nui ʻia nā kila kalapona haʻahaʻa e like me ka No. . Eia kekahi, pono e hoʻopaʻa ʻia nā paipu kila maʻemaʻe i ka wā o ke kaʻina hana, me ka nānā ʻana i ka haku mele, ka hoʻāʻo waiwai mechanical, ka hoʻāʻo ʻana i ka wai, a me nā mea ʻē aʻe, e hōʻoia i ko lākou hilinaʻi a palekana ma lalo o nā kūlana hana. He mea koʻikoʻi nō hoʻi ke kaʻina hana o nā paipu kila carbon seamless. Loaʻa ia i nā ʻanuʻu he nui e like me ka perforation, ka ʻōwili wela, ka ʻōwili anu a i ʻole ke kiʻi anu o nā ingots a i ʻole nā ​​paipu paʻa, a ʻo kēlā me kēia ʻanuʻu e koi i ka mana pololei e hōʻoia i ka maikaʻi o ka huahana hope. No ka laʻana, ʻo ka hana ʻana o nā paipu kila liʻiliʻi i ʻōwili ʻia e pono ai ka hoʻomehana ʻana i ka paipu paipu i kahi o 1200 degere Celsius, a laila e hou ʻia i loko o kahi perforator, a laila hana i ka paipu kila ma o ʻekolu-roller oblique rolling, hoʻomau i ka ʻōwili a extrusion. Pono nā paipu kila liʻiliʻi i ʻōwili ʻia i ka paipu paipu e ʻohi ʻia a lubricated ma mua o ka ʻōwili ʻia ʻana (kau ʻia) e loaʻa ai ka nui a me ke ʻano i makemake ʻia. ʻO kēia mau kaʻina hana paʻakikī ʻaʻole wale e hōʻoia i ka maikaʻi o loko o ka paipu kila maʻemaʻe, akā hāʻawi pū kekahi i ka pololei o ka dimensional a me ka pau ʻana o ka ʻili. Ma nā hoʻohana pono, hoʻohana nui ʻia nā paipu kila carbon seamless i nā ʻoihana he nui e like me ka aila, gas, ʻoihana kemika, uila, wela, mālama wai, kūkulu moku, a me nā mea ʻē aʻe ma muli o kā lākou hana maikaʻi loa a me ka hilinaʻi. He ʻāpana koʻikoʻi lākou o ka ʻoihana hou. Inā i loko o ka wela wela a me ke kaomi kiʻekiʻe a i ʻole i ka media corrosive, hiki i nā paipu kila carbon seamless ke hōʻike i kā lākou hana maikaʻi loa a hāʻawi i nā hōʻoia paʻa no ka hana palekana o nā ʻōnaehana ʻoihana like ʻole.

ʻO ke anawaena o nā paipu kila kalapona liʻiliʻi hiki ke loaʻa mai DN15 a DN2000mm, ʻokoʻa ka mānoanoa o ka pā mai 2.5mm a 30mm, a ʻo ka lōʻihi ma waena o 3 a me 12m. Hāʻawi kēia mau ʻāpana dimensional i nā paipu kila carbon seamless e hana paʻa ma lalo o ke kaomi kiʻekiʻe a me nā wahi wela kiʻekiʻe, ʻoiai e hōʻoiaʻiʻo ana i ko lākou hilinaʻi i ka wā o ka lawe ʻana a me ke kau ʻana. Wahi a GB / T 17395-2008 maʻamau, ʻo ka nui, ke ʻano, ke kaumaha a me ka ʻae ʻia ʻana o ka hoʻokaʻawale ʻana o nā paipu kila seamless e hoʻoponopono pono ʻia e hōʻoia i ka maikaʻi o ka huahana a me ka palekana. Ke koho ʻana i nā paipu kila carbon seamless, he mea nui e noʻonoʻo i ko lākou anawaena o loko, ka anawaena o waho, ka mānoanoa a me ka lōʻihi, ʻo ia nā mea nui i ka hoʻoholo ʻana i ka hana o ka pipeline. No ka laʻana, ʻo ke anawaena o loko e hoʻoholo ai i ka nui o ke ākea e hele ai ka wai, ʻoiai ʻo ke anawaena o waho a me ka mānoanoa e pili pono ana i ka hiki ke hoʻoikaika i ka paipu. Hoʻopili ka lōʻihi i ke ʻano pili o ka paipu a me ka paʻakikī o ke kau ʻana.
