He nui nā ʻano a me nā nui o nā paipu kila. ʻO ka paipu humuhumu ʻole kahi koho i hana ʻole ʻia, i hana ʻia me ka billet kila i hoʻomoe ʻia. I ka wā e pili ana i nā paipu kila i hoʻoheheʻe ʻia, aia ʻekolu mau koho: ERW, LSAW a me SSAW.
Hana ʻia nā paipu ERW me nā papa kila i hoʻopaʻa ʻia me ke kū'ē. Hana ʻia ka paipu LSAW me ka papa kila i hoʻopaʻa ʻia me ke arc i lalo o ka wai. Hana ʻia ka paipu SSAW me ka papa kila i hoʻopaʻa ʻia me ke arc i lalo o ka wai.
E nānā pono kākou i kēlā me kēia ʻano paipu, e hoʻohālikelike i ko lākou ʻokoʻa, a pehea e hoʻohana ai i ka wehewehe pololei e kauoha ai.
Paipu kila humuhumu ʻole
Hana ʻia ka paipu humuhumu ʻole me ka billet kila kila, kahi i hoʻomehana ʻia a puka ʻia e hana i kahi ʻāpana hakahaka poepoe. No ka mea, ʻaʻohe wahi wili o ka paipu humuhumu ʻole, ua manaʻo ʻia he ʻoi aku ka ikaika ma mua o ka paipu wili ʻia a emi iki ka maʻalahi i ka pala, ka ʻino a me ka hāʻule ʻana.
Eia nō naʻe, ʻo ke kumukūʻai no kēlā me kēia tona o ka paipu humuhumu ʻole he 25-40% kiʻekiʻe aʻe ma mua o ka paipu ERW. ʻO ka nui o nā paipu kila humuhumu ʻole mai 1/8 ʻīniha a 36 ʻīniha.
Paipu kuʻihao kū'ē (ERW)
Hoʻokumu ʻia ka paipu kila ERW (kuʻihao kū'ē) ma ka ʻōwili ʻana i ke kila i loko o ka paipu a hoʻohui i nā wēlau ʻelua me ʻelua mau electrodes keleawe. He ʻano disc kēia mau electrodes a wili i ka wā e hele ai ka mea ma waena o lākou. ʻAe kēia i ka electrode e mālama i ka pilina mau me ka mea no ka manawa lōʻihi o ka kuʻihao mau. Ke hoʻomau nei ka holomua o ka ʻenehana kuʻihao i ka hoʻomaikaʻi ʻana i kēia kaʻina hana.
He pani waiwai a kūpono hoʻi ka paipu ERW no ka paipu kila humuhumu ʻole, ʻoi aku ka paʻa ma mua o ka paipu SAW. Ke hoʻohālikelike ʻia me ke kaʻina hana hoʻoheheʻe i hoʻohana ʻia i loko o ka paipu welded arc i hoʻopaʻa ʻia, ʻaʻole paha e loaʻa nā hemahema, a hiki ke ʻike maʻalahi ʻia nā hemahema welded pololei e ka noʻonoʻo ultrasonic a i ʻole ka ʻike.
ʻO ke anawaena o ka paipu ERW mai nā ʻīniha (15 mm) a i 24 ʻīniha (21.34 mm).
Paipu i hoʻopaʻa ʻia i loko o ka wai
ʻO LSAW (straight seam welding) a me SSAW (spiral seam welding) he mau ʻano like ʻole o ka paipu i hoʻopaʻa ʻia i loko o ka wai. Hoʻopuka ke kaʻina hana hoʻopaʻa ʻia i loko o ka wai i ka nui o ke au e pale aku ai i ka hoʻopuehu wikiwiki ʻana o ka papa flux a hoʻopaʻa i loko o ka wahi hoʻopaʻa.
ʻO ka ʻokoʻa nui ma waena o nā paipu LSAW a me SSAW ʻo ia ke kuhikuhi o ka weld, kahi e hoʻopilikia ai i ka hiki ke halihali kaomi a me ka maʻalahi o ka hana ʻana. Hoʻohana ʻia ʻo LSAW no nā noi voltage waena a i ke kiʻekiʻe, a hoʻohana ʻia ʻo SSAW no nā noi voltage haʻahaʻa. ʻOi aku ke kumukūʻai o nā paipu LSAW ma mua o nā paipu SSAW.
Paipu wili ʻia i hoʻopaʻa ʻia i loko o ka wai
Hana ʻia ka paipu LSAW ma ka hana ʻana i ka ʻōmole kila wili wela i loko o kahi cylinder a hoʻohui i nā wēlau ʻelua ma o ka hoʻopili ʻana i ka wili linear. Hoʻokumu kēia i kahi paipu i hoʻopili ʻia me ka longitudinal. Hoʻohana nui ʻia kēia mau paipu no nā paipu hoʻoili mamao loa o ka ʻaila, ke kinoea kūlohelohe, ka lanahu wai, nā hydrocarbons, a pēlā aku.
ʻElua ʻano paipu LSAW: ke kaula longitudinal hoʻokahi a me ke kaula pālua (DSAW). Hoʻokūkū ka paipu kila LSAW me ka paipu kila seamless a me ka paipu kila ERW 16 a 24 ʻīniha. I ka ʻoihana aila a me ke kinoea kūlohelohe, hoʻohana ʻia nā paipu API 5L LSAW nui-diameter no ka lawe ʻana i nā hydrocarbons i kahi mamao a me ka maikaʻi.
ʻO ke anawaena o ka paipu LAW ma waena o 16 ʻīniha a me 60 ʻīniha (406 mm a me 1500 mm).
ʻAʻohe ʻano - nā koena pahū o ke kaua - ka wiliwili ʻana i lalo o ka wai - ka wiliwili ʻana i lalo o ka wai - ka paipu - ka wiliwili ʻana i lalo o ka wai
Paipu SSAW
Hoʻokumu ʻia ka paipu kila SSAW ma ka ʻōwili ʻana a me ka hoʻopili ʻana i ke kaula kila ma ke kuhikuhi wili a i ʻole ka wili e hana i ka wili. ʻO ke kaʻina hana wili e hiki ai ke hana i nā huahana anawaena nui. Hoʻohana nui ʻia nā paipu kila wili no ka hoʻoili wai haʻahaʻa, e like me nā paipu ma nā kahua kai, nā hale hana petrochemical a i ʻole nā hale hana moku, a me nā hale kīwila a me nā pili.
ʻO ka laulā o ke anawaena paipu o SSAW he 20 ʻīniha a 100 ʻīniha (406 mm a 25040 mm).
Pehea e kauoha ai i nā paipu kila no kāu papahana
I ke kauoha ʻana i nā paipu kila, aia ʻelua mau ana koʻikoʻi: ka nui o ka paipu maʻamau (NPS) a me ka mānoanoa o ka paia (papa kuhikuhi). No nā paipu ma lalo o 4 ʻīniha, hiki i ka lōʻihi o ka paipu ke hoʻokahi random (SRL) 5-7 mika, a no nā paipu ma mua o 4 ʻīniha, hiki i ka lōʻihi o ka paipu ke pālua random (DRL) 11-13 mika. Loaʻa nā lōʻihi maʻamau no nā paipu lōʻihi. Hiki i nā wēlau o ka paipu ke bevel (be), plane (pe), thread (THD) thread and coupling (T&C) a i ʻole groove.
Hōʻuluʻulu manaʻo o nā kikoʻī kauoha maʻamau:
ʻAno (seamless a welded paha)
Ka nui o ka paipu inoa
Papa kuhikuhi
ʻAno hopena
Papa mea
Ka nui ma nā mika a i ʻole kapuaʻi a i ʻole tone.
Inā ʻoe e noʻonoʻo ana e kūʻai i ka SEAMLESS PIPE, ERW PIPE, SSAW PIPE A I ʻOLE LSAW PIPE, e nānā i nā koho a JINDALAI nou a e noʻonoʻo e hoʻokaʻaʻike aku i kā mākou hui no ka ʻike hou aku. E hāʻawi mākou iā ʻoe i ka hopena maikaʻi loa no kāu papahana.
E leka uila mai iā mākou i kēia manawa!
