Hoʻokumu ʻia ka paipu kila composite me ʻelua (a ʻoi aku paha) mau mea i hui ʻia i hoʻokahi ma o nā ʻano ʻenehana kikoʻī i loaʻa iā ia nā hiʻohiʻona piha.
Mai ka 1960s, Iapana, ʻAmelika Hui Pū ʻIa, Kelemānia, United Kingdom a me nā ʻāina ʻē aʻe i hoʻopili nui i ka hoʻomohala ʻana i ke kila composite.PTFE laina paipu, Ua hoʻohana nui ʻia nā huahana paipu kila composite i ka ikehu, ka hana moku, kemika, ka aila a me nā mīkini a me nā māla ʻē aʻe.ʻO ka ʻenehana hoʻoheheʻe ʻia ʻana o ka paipu kila hui pū me ka ʻōwili, hoʻolei, extrusion, brazing, welding a pēlā aku.
- 1.Application laula o ka paipu kila composite
ʻO ke ʻano hui pū ʻana o ʻelua ʻano o nā mea papa hoʻokahi o ka paipu i hoʻopaʻa ʻia i ke kila hui pū ʻia e pili pono ana i nā koi noi a me nā ʻano kūlohelohe.ʻO ka paipu kila kumu ka ikaika kiʻekiʻe a me ka rigidity, ke kumu kūʻai haʻahaʻa a me ka hana hana maikaʻi.ʻO ka paipu kila i uhi ʻia he paʻakikī kiʻekiʻe a loaʻa iā ia ka hiki ke pale aku i ka corrosion o ka mea kaiapuni.Hiki i kēia papa ke komo i loko o ka paipu kila hui (inner composite pipe) a i ʻole ma ka ʻaoʻao o waho (outer composite pipe). E like me ke ʻano o ka hoʻohana ʻana hiki ke hoʻokaʻawale ʻia i loko o ka hoʻohana kemika wai paipu kinoea, aila a me ke kinoea pipeline a me ka aila. ka paipu maikaʻi, ka paila, ka ʻōpala ʻōpala me ka nui o ka paipu, ka paipu no ka hoʻololi ʻana i ka wela, me ka pale ʻana i ka ʻaʻahu, ke ʻano o ka pale ʻana i ka corrosion me ka nui o ka paipu a me ka paipu hoʻonaninani hale, a me nā mea ʻē aʻe, me ka hoʻomohala mau ʻana o ka noi ʻenehana paipu composite, ka laulā noi o ka composite. e hoʻonui ʻia ka paipu i nā kahua noi ākea.
- 2. Hana hana opaipu kila hui
Hiki ke hoʻokaʻawale ʻia nā paipu kila composite i ʻelua ʻano, bimetallic a me ka papalua, e like me ke kūlana hui o nā pilina pili o nā ʻano paipu kila ʻelua.ʻO ka paipu kila hui pū me ka pilina pili o loko a me waho e pili ana i ka metallurgical bonding degree i kapa ʻia ʻo bimetallic pipe, ʻoiai ka pili pili o ka ʻaoʻao o loko a me waho e hiki wale i ka pili mechanical, a ʻo ka paipu kila hui me ka ʻāpana longitudinal ʻāpana a me ka papa i hoʻokaʻawale ʻia. kapa ʻia ka paipu papa pālua.Nui nā ʻano kaʻina hana no ka hana ʻana i nā paipu kila composite, ʻo kēlā me kēia mea nona nā ʻano ponoʻī a me ka laulā noi.
- 2.1 Kaʻina hana wela
Ma kēia ʻano, hoʻohana ʻia ka billet kila kalapona maʻamau ma ke ʻano he metala kumu waho, wili ʻia ka lua waena, a hoʻohana ʻia ke kila kila a i ʻole ke koʻokoʻo nickel alloy ma ke ʻano he papa o loko.ʻO waho e hōʻoiaʻiʻo i nā waiwai kino o ka paipu hui, nā koi ʻino o ka paipu i loko, i ka wā e hoʻomaʻemaʻe ai ka pā a me ka billet ma hope o ka maʻemaʻe o ka lua o loko, e hoʻopaʻa ʻia ka lua billet o ka paipu, e hoʻopaʻa i ka sila i nā wēlau o ka paipu, hoʻohana i ka pae. o ka haʻahaʻa haʻahaʻa induction coil e hoʻomalu i ka wela, ma hope o ka wela e hoʻonoho i ka mahana, ma 1 600 t wela punch ma ka mīkini paʻi hydraulic vertical, paipu paipu i ke ʻano perforation circular a me ka axial compressed gauge pōʻai perforation, ma hope o ka thermal perforated tube billet, bar a me ka mea kumu i ka hui metallurgical.Hoʻohana ʻia kēia kaʻina hana e Tubacex, he hui paipu kila extruded Spanish, e hana i nā paipu kila hui me nā anawaena o waho o 60· 3 a me 219 · Imm.ʻO ka mānoanoa o ka paipu pale pale corrosion he 10% a i ka 0% o ka mānoanoa a pau o ka paipu laina i hui pū ʻia, ma waena o 2 knm a me 1 knm ka liʻiliʻi loa.
- 2.2 Keʻano wiliwili pā kila hui
Hiki ke hoʻohana ʻia kēia ʻano hana no ka hana ʻana i nā paipu kila composite no nā pipeline hoʻouna ʻaila a me ke kinoea me nā anawaena ʻoi aku ka nui ma mua o 300mm. Ua ʻōwili ʻia ka pā kila hui i loko o ka paipu paipu ma ke kaʻina UO, a laila welded i loko o ka hili longitudinal.ʻO ke kaʻina hana o ka paipu kila composite i hana ʻia e kēia ʻano hana penei: longitudinal seam welding - pipe expanding - wela wela o ke kila i-jo hana billet.
- 2.3 Kaʻina anuu diffusion annealing
Hoʻohana ʻia nā paipu paipu o nā mea like ʻole i ʻōwili ʻia a i ʻole i huki ʻia i ke anu.ʻO kahi kāʻei lahilahi haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa e hoʻoheheʻe ʻia a puni ka ʻaoʻao o waho o ka papa o loko o nā paipu paipu.Ma hope o ke kaha ki'i anu, ho'okō 'ia ka annealing diffusion ki'eki'e.ʻO ka hiʻohiʻona o ka hui pū ʻana o ka paipu laina laina i hana ʻia e kēia kaʻina hana ʻo ia ka ʻike ʻana o ka palena hui a maopopo loa.Ma muli o ka hoʻohui ʻia ʻana o kahi pae hoʻoheheʻe haʻahaʻa ma waena o nā mea hoʻopili paʻa ʻelua, ʻoi aku ka kiʻekiʻe o kona ikaika paʻa, ʻoi aku ka nui ma mua o 300MPao.ʻO ka haʻahaʻa hoʻoheheʻe haʻahaʻa metala gasket mea maʻamau ʻo Ni - P alloy, a ʻo kona helu hoʻoheheʻe ʻana e emi iho ana me ka piʻi ʻana o ka maʻiʻo o P. ʻO nā gaskets ʻē aʻe he B (1, 4Wt%), Si (a hiki i 9Wt %), cr (hiki i ka 30Wt%) hao - a i ʻole nā mea hoʻohui ni-based.Pono e emi ka helu hehee o ka mea gasket ma mua o ka paipu kumu waho a me ka paipu loko.Hiki i ka paipu kila composite i hana ʻia e kēia kaʻina hana ke kūpaʻa i ka hoʻokumu ʻana, a hiki i kona kikoʻī a me ka maikaʻi o ka ʻili ke hoʻokō i nā koi maʻamau.
