Hiki mai nā paipu kila ma nā ʻano a me nā nui.ʻO ka paipu seamless kahi koho non-welded, i hana ʻia me ka billet kila hollowed.I ka wā e pili ana i nā paipu kila welded, aia ʻekolu mau koho: ERW, LSAW a me SSAW.
Hana ʻia nā paipu ERW i nā pā kila welded.Hana ʻia ka paipu LSAW me ka longitudinal submerged arc welded steel plate.Hana ʻia ka paipu SSAW me ka pā kila arc submerged arc.
E nānā pono kākou i kēlā me kēia ʻano paipu, e hoʻohālikelike i ko lākou mau ʻokoʻa, a pehea e hoʻohana ai i ka wehewehe kūpono e kauoha ai.
Paipu kila ʻole
Hana ʻia ka paipu seamless me ka billet kila kila, i hoʻomehana ʻia a hoʻoheheʻe ʻia e hana i kahi ʻāpana hollow poʻe.No ka mea, ʻaʻohe wahi kuʻikuʻi, ua manaʻo ʻia ʻoi aku ka ikaika ma mua o ka paipu welded a liʻiliʻi i ka corrosion, erosion a me ka hemahema maʻamau.
Eia nō naʻe, ʻo ke kumukūʻai o ka paipu seamless he 25-40% kiʻekiʻe ma mua o ka paipu ERW.Mai ka 1/8 iniha a hiki i ka 36 iniha ka nui o ka paipu kila lauwili.
Paipu hoʻoheheʻe kūʻē (RW).
Hoʻokumu ʻia ʻo ERW (resistance welding) paipu kila ma ka ʻōwili ʻana i ke kila i loko o ka paipu a hoʻohui i ʻelua mau kihi me ʻelua electrodes keleawe.ʻO kēia mau electrodes he disc-like a huli i ka wā e hele ai ka mea ma waena o lākou.ʻAe kēia i ka electrode e mālama mau i ka pilina me ka mea no ka manawa lōʻihi o ka hoʻomau mau ʻana.Ke hoʻomau nei ka holomua o ka ʻenehana welding i kēia kaʻina hana.
ʻO ka paipu ERW kahi mea waiwai a kūpono hoʻi no ka paipu kila ʻole, ʻoi aku ka lōʻihi ma mua o ka paipu SAW.Ke hoʻohālikelike ʻia me ke kaʻina hoʻoheheʻe i hoʻohana ʻia i loko o ka paipu wili arc submerged, ʻaʻole paha e hiki mai nā hemahema, a hiki ke ʻike maʻalahi ʻia nā hemahema weld pololei e ka noʻonoʻo ultrasonic a i ʻole ka ʻike.
Aia ke anawaena o ka paipu ERW mai iniha (15 mm) a i 24 iniha (21.34 mm).
Piula wiliwili ʻia i loko o ka wai
ʻO LSAW (kuʻi kuʻi pololei) a me SSAW (kui kuʻikuʻi spiral) he mau ʻano like ʻole o ka paipu wili arc i lalo.ʻO ke kaʻina hana kuʻikuʻi arc i hoʻopaʻa ʻia e hoʻopuka i ka nui o kēia manawa no ka pale ʻana i ka hoʻoheheʻe ʻana o ka wela wikiwiki o ka papa flux a kau i ka wahi kuʻi.
ʻO ka ʻokoʻa nui ma waena o nā paipu LSAW a me SSAW ʻo ia ke kuhikuhi o ka weld, e pili ana i ka hiki ke hoʻoikaika a me ka maʻalahi o ka hana.Hoʻohana ʻia ʻo LSAW no nā noi haʻahaʻa haʻahaʻa haʻahaʻa.ʻOi aku ke kumukūʻai o nā paipu LSAW ma mua o nā paipu SSAW.
ʻO ka paipu welded arc longitudinal submerged
Hana ʻia ka paipu LSAW ma ka hana ʻana i ka ʻili kila ʻōwili wela i loko o ka cylinder a hoʻohui i nā wēlau ʻelua me ka wili laina.Hoʻokumu kēia i kahi paipu longitudinally welded.Hoʻohana nui ʻia kēia mau pipelines no nā pipeline hoʻouna lōʻihi o ka aila, ke kinoea maoli, ka lanahu wai, hydrocarbons, etc.
ʻElua ʻano paipu LSAW: hoʻokahi hili lōʻihi a me ka hili pālua (DSAW).Paipu kila LSAW me ka paipu kila ʻole a me ka paipu kila ERW 16 a 24 iniha.I loko o ka ʻoihana aila a me ke kinoea maoli, hoʻohana ʻia nā paipu API 5L LSAW nui-diameter no ka lawe ʻana i nā hydrocarbons lōʻihi.
ʻO ke anawaena o ka paipu LAW ma waena o 16 iniha a me 60 iniha (406 mm a me 1500 mm).
ʻAʻohe - nā koena pahū o ke kaua - wiliwili arc submerged longitudinal - wiliwili arc submerged arc - pipeline - wiliwili arc submerged spiral
paipu SSAW
Hoʻokumu ʻia ka paipu kila SSAW ma ka ʻōwili ʻana a me ka hoʻopaʻa ʻana i ke kaula kila ma ka spiral a i ʻole ka ʻaoʻao spiral e hana i ka weld i loko o ka spiral.ʻO ke kaʻina hana wiliwili spiral hiki ke hana i nā huahana nui-diameter.Hoʻohana nui ʻia nā paipu kila spiral no ka hoʻouna ʻana i ka wai haʻahaʻa haʻahaʻa, e like me nā pipelines ma nā kahua o waho, nā mea kanu petrochemical a i ʻole nā hale moku, a me nā hale kīwila a me ka piling.
ʻO ke anawaena paipu o SSAW he 20 mau ʻīniha a 100 iniha (406 mm a 25040 mm).
Pehea e kauoha ai i nā paipu kila no kāu papahana
I ke kauoha ʻana i nā paipu kila, ʻelua mau ʻano nui: ka nui o ka paipu nominal (NPS) a me ka mānoanoa o ka pā (papa).No nā paipu i emi iho ma mua o 4 iniha, hiki i ka lō'ihi o ka paipu ke ho'okahi random (SRL) 5-7 mika, a i 'ole no ka paipu 'oi aku ma mua o 4 iniha, hiki i ka paipu ke ho'olua palua (DRL) 11-13 mika.Loaʻa nā lōʻihi maʻamau no nā paipu lōʻihi.Hiki i nā wēlau paipu ke bevel (be), plane (pe), thread (THD) thread a me ka hoʻohui ʻana (T&C) a i ʻole groove.
Hōʻuluʻulu o nā kikoʻī kauoha maʻamau:
ʻAno (seamless a welded)
Nui paipu inoa
Papa kuhikuhi
ʻAno hoʻopau
Papa waiwai
Ka nui i nā mika a i ʻole nā wāwae a i ʻole nā tona.
Inā ʻoe e noʻonoʻo ana e kūʻai aku i ka SEAMLESS PIPE, ERW PIPE, SSAW PIPE a i ʻole LSAW PIPE, e ʻike i nā koho a JINDALAI no ʻoe a noʻonoʻo e kelepona i kā mākou hui no ka ʻike hou aku.E hāʻawi mākou iā ʻoe i ka hopena maikaʻi loa no kāu papahana.
E kelepona mai iā mākou i kēia manawa!
