Paipu kila kalapona anawaena nuie nānā maʻamau i nā paipu kila kalapona me ke anawaena o waho ma lalo o 200mm. Hana ʻia mai ke kila kalapona, ʻo ia nā mea koʻikoʻi i ka ʻoihana ʻoihana a me nā ʻoihana ma muli o ko lākou ikaika kiʻekiʻe, paʻakikī maikaʻi, a me nā waiwai wili maikaʻi. Hoʻohana mau ʻia ka wili wela a me ka spiral i kā lākou hana.ʻO nā paipu kila ʻōwili welahoʻohana nui ʻia i nā noi kiʻekiʻe ma muli o ko lākou mānoanoa pā like ʻole a me ke ʻano paʻa.

Nā ʻōlelo kikoʻī i hoʻopilikino ʻia: E hālāwai me nā makemake o nā papahana like ʻole

Ua wehewehe ʻia nā kikoʻī kikoʻī o ka paipu kalapona kalapona nui e ke anawaena o waho, ka mānoanoa o ka paia, ka lōʻihi, a me ka pae waiwai. ʻO nā anawaena o waho mai ka 200 mm a 3000 mm. ʻO ia mau nui nui e hiki ai iā lākou ke lawe i nā kahe wai nui a hāʻawi i ke kākoʻo hoʻolālā, pono no nā papahana nui.

ʻO ka paipu kila ʻōwili wela ke kū i waho no kāna mau hana hana pono: ʻo ka ʻōwili wela kiʻekiʻe e hoʻololi i nā pila kila i mau paipu me ka mānoanoa pā like ʻole a me ke ʻano o loko. Hiki ke ho'omalu 'ia kona anawaena o waho ma loko o ± 0.5%, i mea e kūpono ai i nā papahana me nā koi 'ano nui, e like me nā paipu mahu i nā mea mana wela nui a me nā pūnaewele ho'omehana kūloko o ke kūlanakauhale.

Q235 paipu kila kalaponaaA36 paipu kila kalaponaloaʻa nā palena kikoʻī maopopo no nā māka mea like ʻole.

1.Q235 paipu kila: He paipu kila kila Q235 ma Kina. Me ka ikaika hua o 235 MPa, hana maʻamau ia i ka mānoanoa o ka pā o 8-20 mm a hoʻohana mua ʻia no nā noi kaʻa wai haʻahaʻa haʻahaʻa, e like me ka lako wai a me ka hoʻoheheʻe ʻana, a me nā pipeline kinoea.

2.A36 paipu kila kalapona: ʻO A36 carbon steel pipe ka papa kila nui ma ka mākeke honua. Loaʻa iā ia kahi kiʻekiʻe kiʻekiʻe o ka ikaika (250MPa) a ʻoi aku ka maikaʻi o ka ductility. Hoʻohana nui ʻia kona ʻano nui-anawaena (maʻamau me ka anawaena o waho o 500mm a ʻoi aku paha) i ka ʻaila a me ke kinoea e hōʻiliʻili ai a me nā pipeline halihali, pono e kū i kekahi mau kaomi a me nā loli wela.

Hoʻohana ʻana i ka paipu hao kalapona ke anawaena nui

ʻO ka paipu kalapona kalapona nui, me kona mau pono o ka ikaika kiʻekiʻe, ke kūpaʻa kiʻekiʻe, ka wili maʻalahi, a me ka maikaʻi o ke kumu kūʻai, he mau mea hiki ke hoʻololi ʻia i nā ʻāpana kī he nui. Hiki ke hoʻokaʻawale ʻia kēia mau noi i ʻekolu mau wahi nui: ka hoʻoili ʻana i ka ikehu, ka ʻenehana ʻenehana, a me ka hana ʻenehana.

Hoʻoili ikehu: He "aorta" no ka aila, kinoea, a me ka mana. Hoʻohana ʻia nā paipu aila a me ke kinoea holoʻokoʻa (e like me ka Central Asia Natural Gas Pipeline a me ka West-East Gas Pipeline) e hoʻohana i ka paipu kalapona kalapona nui (ka hapa nui me ka anawaena o waho o 800-1400mm).

Infrastructure and municipal engineering: Kākoʻo ia i ka hana o nā kūlanakauhale a me nā ʻoihana kaʻa. I loko o ka lako wai a me ka hoʻoheheʻe ʻana, ʻo ka paipu kila kalapona nui (ka anawaena o waho 600-2000mm) ʻo ia ka mea i koho maikaʻi ʻia no nā paipu wai nui o ke kūlanakauhale a me nā paipu hoʻoheheʻe wai ʻino ma muli o kona kūpaʻa ʻana (me ke ola ma mua o 30 mau makahiki ma hope o ka anti-corrosion coating treatment) a me ke kahe kiʻekiʻe.

Hana ʻenehana: He iwi kuamoʻo o ka hana kaumaha a me ka hana kemika. Hoʻohana pinepine nā mea kanu mīkini kaumaha i nā paipu kila kalapona nui (15-30mm ka mānoanoa o ka paia) no nā kākoʻo kaʻa crane a me nā papa kumu lako nui. ʻO kā lākou mau haʻahaʻa haʻahaʻa kiʻekiʻe (hiki i kahi paipu hoʻokahi ke kūpaʻa i nā ukana kūpaʻa ma mua o 50kN) kōkua i ka hoʻopaʻa ʻana i ka hana o nā mea hana.

Nā Kūlana Makeke a me ka Manaʻo ʻOihana: Ke ulu nei ka makemake no nā paipu kiʻekiʻe

Ke piʻi mau nei ka noi o ka mākeke no nā paipu kila kalapona nui me ka ʻoihana honua, ka ikehu, a me ka hoʻomohala ʻana i nā ʻoihana. ʻO nā ʻāpana kuʻuna e like me ka petrochemical, ka hoʻouna ʻana i ka mana, a me ka lako wai o ke kūlanakauhale a me ka hoʻoheheʻe ʻana e noho mau i nā kumu nui o ka noi. Ke hoʻomau nei ka ulu ʻana o ka makemake no nā paipu kalapona kalapona nui i loko o ka ʻoihana petrochemical, me ka koi makahiki i manaʻo ʻia e hiki i kahi kokoke i 3.2 miliona tons i ka makahiki 2030. Ke hilinaʻi nei kēia ʻoihana i nā paipu kila kalapona nui no ka lawe ʻana i ka ʻaila kino, nā huahana i hoʻomaʻemaʻe ʻia, a me nā mea kemika.
