Pipa wiliwili ʻole ʻia
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 wiliwili like ʻole, hiki ke hoʻokaʻawale ʻia i ʻelua ʻano: ka paipu wili wili pololei a me ka paipu wiliwili spiral.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.

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.

Hoʻokaʻawale ʻia e ke kumu
Ua māhele ʻia i ka paipu welded maʻamau, paipu wīwī wīwī, paipu hoʻoheheʻe oxygen-puhi, pahu uwea, metric welded paipu, paipu huila, paipu hohonu punawai, paipu kaʻa, paipu transformer, paipu uila wiliwili ʻia i ka paia, uila wili kūikawā- paipu kino, paipu scaffolding a me ka paipu wiliwili wiliwili .
Paipu welded maʻamau:Hoʻohana ʻia ka paipu welded maʻamau no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa.Hana ʻia me Q195A, Q215A, Q235A kila.Hiki ke hana ʻia me nā kila māmā ʻē aʻe i maʻalahi ke wili.Pono e hoʻokau ʻia nā paipu kila i ke kaomi wai, kulou, palahalaha a me nā hoʻokolohua ʻē aʻe, a aia kekahi mau koi i ka maikaʻi o ka ʻili.ʻO ka manawa maʻamau ka lōʻihi o ka lawe ʻana he 4-10m, a ʻo ka hoʻouna ʻana i ka lōʻihi paʻa (a i ʻole ka lōʻihi pālua) e koi pinepine ʻia.Hōʻike ʻia nā kikoʻī o nā paipu welded e ke anawaena nominal (mm a i ʻole iniha).ʻOkoʻa ke anawaena nominal o nā paipu welded mai nā mea maoli.E like me ka mānoanoa o ka paia i kuhikuhi ʻia, loaʻa nā paipu welded i nā paipu kila maʻamau a me nā paipu kila mānoanoa.Hoʻokaʻawale ʻia nā paipu kila i ʻelua ʻano me ka milo a me ka ʻole o ke kaula e like me ke ʻano o ka hopena tube.
Paipu kila galvanized:I mea e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion o ka paipu kila, ua galvanized ka paipu kila maʻamau (pipa ʻeleʻele).Hoʻokaʻawale ʻia nā paipu kila galvanized i ʻelua ʻano: hot-dip galvanizing a me electro-galvanizing.He mānoanoa ka papa galvanizing wela a he haʻahaʻa ke kumukūʻai o ka electro-galvanizing.
Paipu wiliwili puʻu ʻoxygen:Hoʻohana ʻia ma ke ʻano he paipu hoʻoheheʻe oxygen, maʻamau, hoʻohana ʻia nā paipu kila liʻiliʻi liʻiliʻi, me ʻewalu mau kikoʻī mai 3/8 iniha a 2 iniha.Hana ʻia ʻo 08, 10, 15, 20 a i ʻole Q195-Q235 kāʻei kila.I mea e pale ai i ka corrosion, ua alumini ʻia kekahi.
Uea pahu:ʻO ke kila kalapona maʻamau i hoʻopaʻa ʻia i ka paipu kila, hoʻohana ʻia i loko o nā pāhana hoʻokaʻawale mana a me nā ʻano hana like ʻole, ʻo ke anawaena nominal maʻamau mai 13-76mm.He lahilahi ka paia o ka lima uea, a ua hoʻohana ʻia ka hapa nui ma hope o ka uhi ʻana a i ʻole ka galvanizing, a koi ʻia kahi hoʻāʻo anu.
Metric welded paipu:Hoʻohana ʻia ka ʻōlelo kikoʻī e like me ke ʻano paipu ʻole, a ʻo ka paipu kila welded i hōʻike ʻia e ke anawaena o waho * ka mānoanoa o ka paia mm, me ka hoʻohana ʻana i ke kila kalapona maʻamau, ke kila kalapona kiʻekiʻe a i ʻole ka ikehu maʻamau haʻahaʻa haʻahaʻa haʻahaʻa kila no ka ʻili wela, ka wili anu a wela paha. welding welding A laila hana ʻia me ke ʻano kelepona anu.Hoʻokaʻawale ʻia nā paipu welded metric i ka ikehu maʻamau a me nā paia lahilahi, a hoʻohana mau ʻia e like me nā ʻāpana hana, e like me nā shafts transmission a i ʻole nā mea lawe wai.Hoʻohana ʻia nā paipu pā lahilahi e hana i nā lako, nā kukui, a me nā mea ʻē aʻe, a pono e hōʻoia i ka ikaika a me ka hoʻāʻo ʻana o ka paipu kila.
Paipu huila:Uila welded kila paipu no ka wili o ke kāʻei conveyor, hana maʻamau o Q215, Q235A, B kila a me 20 kila, me ke anawaena o 63.5-219.0mm.Aia kekahi mau koi no ka piko o ka paipu, ke alo o ka hope e kū pololei i ka laina waena, a me ka ellipticity.ʻO ka maʻamau, lawe ʻia nā hoʻokolohua wai a me nā hoʻāʻo palahalaha.
Paipu Transformer:Hoʻohana ʻia ia e hana i nā paipu radiator transformer a me nā mea hoʻololi wela ʻē aʻe.Hana ʻia ia me ke kila kalapona maʻamau a koi ʻia ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i nā hoʻāʻo hydraulic.Hāʻawi ʻia nā paipu kila i ka lōʻihi paʻa a i ʻole ka lōʻihi ʻelua, a aia kekahi mau koi no ke kuʻi ʻana o ka paipu kila.
Nā paipu ʻano kūikawā:paipu huinahalike, paipu huinahalike, paipu ano papale, puka kila a me na puka aniani i wiliia e ke kila kalapona ma'amau a me 16Mn mau kaula hao, i hoohana nui ia no na apana mīkini mahiai, puka aniani a me na puka, etc.
Weled paipu paia lahilahi:hoʻohana nui ʻia no ka hana ʻana i nā lako, nā mea pāʻani, nā kukui, a me nā mea ʻē aʻe.
Piula wiliwili ʻia:Hana ʻia ia ma ka ʻōwili ʻia ʻana o ke kila kalapona kalapona haʻahaʻa a i ʻole nā mea hao hao haʻahaʻa haʻahaʻa i loko o kahi paipu blank ma kekahi kihi spiral (i kapa ʻia ʻo forming angle), a laila hoʻopaʻa pū i ka humuhumu paipu.Hiki ke hana ʻia me kahi kila Strip ʻoi aku ka nui o nā paipu kila anawaena.Hoʻohana nui ʻia nā paipu welded spiral no ka ʻaila a me nā pipeline kinoea maoli, a ua hōʻike ʻia kā lākou mau kikoʻī e ke anawaena o waho * ka mānoanoa pā.Hiki ke wili ʻia nā paipu wiliwili ma kekahi ʻaoʻao a ma nā ʻaoʻao ʻelua.E hōʻoiaʻiʻo ʻia ka paipu welded e hoʻokō i nā koi e pili ana i ka hoʻāʻo hydraulic, ka ikaika tensile a me ka hana anu ʻana o ka weld.
