ʻO ke ʻano o ka mālama ʻana i ka wela: ka hoʻoponopono ʻana i ka wā kahiko
Mai ka 1930s, me ka hoʻomohala wikiwiki ʻana i ka hana ʻōwili mau ʻana o ka ʻili kiʻekiʻe a me ka holomua o ka welding a me ka ʻenehana nānā ʻana, ua hoʻomaikaʻi mau ʻia ka maikaʻi o nā welds, a ke hoʻonui nei nā ʻano a me nā kikoʻī o nā paipu kila welded.E humuhumu i ka paipu kila.Hoʻokaʻawale ʻia nā paipu kila welded i nā paipu wili wili pololei a me nā paipu spiral welded e like me ke ʻano o nā welds.Hoʻokaʻawale ʻia ma ke ʻano hana: ka hoʻokaʻawale ʻana-arc welded pipe, resistance welded pipe, (kiʻekiʻe alapine, haʻahaʻa alapine) kinoea welded paipu, umu ahi welded paipu.
ʻO nā paipu wiliwili liʻiliʻi liʻiliʻi e wili ʻia e ke humu pololei, ʻoiai ʻo nā paipu wiliwili anawaena nui ka nui o ka spiral welded.E like me ke ano o ka hope o ka paipu kila, ua maheleia i poepoe welded paipu a kūikawā-like (square, rectangular, etc.) welded paipu;e like me nā mea like ʻole a me ka hoʻohana ʻana, ua māhele ʻia i loko o ka wai mining. , e hoʻokaʻawale i ke anawaena o waho * ka mānoanoa o ka pā mai ka liʻiliʻi a i ka nui.
ʻO nā mea maʻamau i hoʻohana ʻia no nā paipu welded: Q235A, Q235C, Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Nib11, 00Cr19Nib18
ʻO nā blanks i hoʻohana ʻia no nā paipu kila welded he mau papa kila a i ʻole nā mea hao hao, i hoʻokaʻawale ʻia i nā paipu welded umu, nā paipu uila welded (resistance welded) a me nā paipu arc welded ma muli o kā lākou kaʻina hana kuʻi.Ma muli o kona mau ʻano hoʻoheheʻe ʻokoʻa, hiki ke hoʻokaʻawale ʻia i ʻelua ʻano:
paipu wiliwili wili pololei a me ka paipu wiliwili wiliwili.Ma muli o kona ʻano hopena, ua hoʻokaʻawale ʻia i loko o ka paipu welded poepoe a me ke ʻano kūikawā (square, flat, etc.) welded pipe.Hoʻokaʻawale ʻia nā paipu welded i nā ʻano like ʻole ma muli o kā lākou mau mea like ʻole a me ka hoʻohana ʻana:
GB/T3091-2008 (Welded steel pipes no ka haʻahaʻa haʻahaʻa kaʻa wai): Hoʻohana nui ʻia no ka lawe ʻana i ka wai, ke kinoea, ka ea, ka aila, ka wai hoʻomehana a i ʻole ka mahu a me nā wai hoʻohaʻahaʻa haʻahaʻa haʻahaʻa a me nā kumu ʻē aʻe.ʻO kāna mea hōʻike: Q235A kila kila.
GB/T14291-2006 (Welded Steel Pipe for Mining Fluid Transport): Hoʻohana nui ʻia no nā paipu kila wili wili pololei no koʻu ea kaomi, hoʻoheheʻe, a me ke kinoea hoʻokuʻu ʻia.ʻO kāna mea hōʻike he Q235A, ke kila B.
GB / T12770-2002 (Stainless steel welded steel pipe for mechanical structure): Hoʻohana nui ʻia no nā mīkini, nā kaʻa, nā kaʻa, nā lako, nā hale hōkele a me nā hale ʻaina a me nā ʻāpana mechanical a me nā ʻāpana hana.ʻO kāna mau mea kikoʻī he 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.
GB/T12771-1991 (Stainless steel welded steel pipe for fluid transport): Hoʻohana nui ʻia no ka lawe ʻana i nā media corrosive haʻahaʻa.ʻO nā mea ʻelele ʻo 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, etc.
Eia hou, welded kuhiliʻole kila paipu no ka hoʻonani (GB / T 18705-2002), kuhiliʻole kila welded paipu no ka hale hoʻonani (JG / T 3030-1995), a welded kila paipu no ka wela exchangers (YB4103-2000).
ʻO ka paipu welded longitudinal he kaʻina hana maʻalahi, kiʻekiʻe ka hana pono, haʻahaʻa kumu kūʻai a me ka hoʻomohala wikiwiki.ʻOi aku ka ʻoi aku o ka ikaika o nā paipu wiliwili spiral ma mua o nā paipu wili wili pololei.Hiki ke hoʻohana ʻia kahi hakahaka ʻoi aku ka liʻiliʻi no ka hana ʻana i nā paipu welded me nā anawaena paipu nui aʻe, a hiki ke hoʻohana ʻia ka billet me ka laulā like e hana i nā paipu welded me nā anawaena paipu like ʻole.Akā ke hoʻohālikelike ʻia me ka paipu seam pololei o ka lōʻihi like, hoʻonui ʻia ka lōʻihi weld e 30-100%, a ʻoi aku ka haʻahaʻa o ka wikiwiki.
ʻO ke anawaena nui a i ʻole nā paipu wili mānoanoa e hana pololei ʻia mai nā pahu kila, ʻoiai ʻo nā paipu wili liʻiliʻi a me nā paipu wiliwili pā lahilahi e pono ke wili pololei ʻia ma o nā ʻāpana kila.A laila, ma hope o ka poli maʻalahi, maikaʻi ke kaha kiʻi.
Pākuʻi: Hoʻopili ʻia ka paipu i hoʻopaʻa ʻia me ke kila kila, no laila ʻaʻole i like ke kiʻekiʻe e like me ka paipu ʻole.
Hoʻohana nui ʻia nā huahana i ka ʻenehana lako wai, ʻoihana petrochemical, ʻoihana kemika, ʻoihana mana, ʻoihana mahiʻai, a me ke kūkulu ʻana i ke kūlanakauhale.ʻO ia kekahi o nā huahana nui 20 i kūkulu ʻia ma koʻu ʻāina.
Hoʻohana ʻia no ka lawe ʻana i ka wai: lako wai a me ka hoʻokahe.Hoʻohana ʻia no ka lawe ʻana i ke kinoea: ke kinoea lanahu, ka mahu, ke kinoea liquefied petroleum.
No nā kumu hana: e like me nā paipu a me nā alahaka;nā paipu no nā kukū, nā alanui, a me nā hale kūkulu.
