ʻO ka paipu kila he pahu kila lōʻihi, i hoʻohana nui ʻia e like me ka pipeline no ka lawe ʻana i nā wai, e like me ka aila, ke kinoea maoli, ka wai, ke kinoea, ka mahu, a me nā mea ʻē aʻe. like, no laila ua hoʻohana nui ʻia Hoʻohana ʻia i ka hana ʻana i nā ʻāpana mechanical a me nā hale ʻenekinia.Hoʻohana pinepine ʻia ia e hana i nā mea kaua maʻamau, nā barela, nā pūpū, a me nā mea ʻē aʻe. ʻO nā paipu kila welded, ʻike ʻia hoʻi ʻo nā paipu welded, no nā paipu kila i hoʻopaʻa ʻia, ʻo ia nā paipu kila i hana ʻia me nā papa kila a i ʻole nā ʻāpana ma hope o ka crimping a me ka hoʻopaʻa ʻana. he 6 mika ka loa.He maʻalahi ke kaʻina hana o ka paipu kila welded, ʻoi aku ka maikaʻi o ka hana ʻana, he nui nā ʻano a me nā kikoʻī, a he liʻiliʻi ka hoʻopukapuka ʻana i nā mea hana, akā ʻoi aku ka haʻahaʻa o ka ikaika ma mua o ka paipu kila seamless.
Hoʻokaʻawale ʻia ka paipu kila welo
Hoʻokaʻawale ʻia e ke ʻano hana
(1) E like me ke kaʻina hana - arc welded pipe, resistance welded pipe (kiʻekiʻe alapine, low frequency), kinoea welded paipu, umu ahi welded paipu
(2) E like me ka weld - straight seam welded pipe, spiral welded pipe
Hoʻokaʻawale ʻia e ke ʻano ʻāpana
(1) Na paipu kila pauku maalahi—paipu kila poepoe, paipu kila huinahalike, paipu kila oval, paipu kila triangular, paipu kila hexagonal, paipu kila rhombus, paipu kila octagonal, poai kila semicircular, a me na mea e ae.
(2) Paipu kila ʻāpana paʻakikī - paipu kila hexagonal like ʻole, paipu kila ʻelima-petal, paipu kila convex pālua, paipu kila concave pālua, paipu kila melon, paipu kila conical, paipu kila corrugated, hihia paipu kila, etc.
Wahi a ka mānoanoa o ka pā, hiki ke hoʻokaʻawale ʻia i: paipu kila lahilahi a me ka paipu kila mānoanoa;
E like me ke ʻano o ka hopena, hiki ke hoʻokaʻawale ʻia i: ka paipu wili a puni a me ke ʻano kūikawā (square, flat, etc.) welded pipe;
Hoʻokaʻawale ma ke kumu
Paipu wiliwili maʻamau, paipu wiliwili wiliwili, paipu hoʻoheheʻe ʻia o ka oxygen, pahu uwea, paipu wiliwili metric, paipu palaualelo, paipu puna wai hohonu, paipu kaʻa, paipu transformer, paipu wiliwili ʻili lahilahi, wili uila, paipu ʻano kūikawā, scaffold paipu a me ka paipu wiliwili spiral.
ʻO ke kumu nui
Hoʻohana nui ʻia ia i ka ʻenekinia lako wai, ʻoihana petrochemical, ʻoihana kemika, ʻoihana mana uila, ʻoihana mahiʻai, a me ke kūkulu kūlanakauhale.ʻO ia kekahi o nā huahana nui i hoʻomohala ʻia e ko mākou ʻāina.
Hoʻohana ʻia no ka lawe ʻana i ka wai: lako wai a me ka hoʻokahe.No ka lawe kinoea: kinoea, mahu, liquefied petroleum gas.
No nā kumu hana: e like me nā paipu pili, e like me nā alahaka;paipu no na uwapo, alanui, hale, etc.
Hoʻokaʻawale ʻia nā paipu kila Welded i galvanized a me non-galvanized e like me ka mālama ʻana o ka paipu.Hiki ke hoʻokaʻawale ʻia nā paipu kila welded i ʻelua mau ʻano ke haʻalele lākou i ka hale hana: ua hoʻopaʻa ʻia kekahi ma ka hope o ka paipu, a ʻaʻole i hoʻopaʻa ʻia kekahi ma ka hope o ka paipu.No nā paipu kila welded me nā kaula ma nā wēlau o ka paipu, ʻo ka lōʻihi o kēlā me kēia paipu he 4-9m, a no nā paipu kila welded me nā kaula ʻole, ʻo ka lōʻihi o kēlā me kēia paipu he 4-12m.
Hoʻokaʻawale ʻia nā paipu kila welded i nā paipu kila lahilahi, nā paipu kila mānoanoa a me nā paipu kila maʻamau e like me ka mānoanoa o ka pā paipu.ʻO nā paipu kila maʻamau ka mea i hoʻohana nui ʻia i nā paipu kaʻina hana, a ʻo kā lākou hoʻāʻo ʻana he 2.0MPa.ʻO ke kaomi hoʻāʻo o ka paipu kila mānoanoa he 3.0MPa.
Nui nā ʻano hoʻohui no nā paipu kila welded, me ka pilina pili, ka pili flange a me ka wili.Hoʻokaʻawale ʻia ka pilina flange i ka pilina flange threaded a me ka pilina flange welding, a ua māhele ʻia ke ʻano kuʻi ʻana i ka welding gas a me ka wili arc.
Hoʻohana maʻamau i hoʻohana ʻia welded kila paipu kikoʻī laulā: nominal anawaena 6 ~ 150mm
Hiki ke hoʻokaʻawale ʻia nā paipu kila Welded i ʻekolu mau ʻāpana e like me ke kaʻina hana:
1. Uila kū'ē welded kila paipu
ʻO ka paipu kila i hoʻopaʻa ʻia i ka uila, ka inoa Pelekane ʻo ERW (Electric resistance welded Pipe), ʻo ke ʻano weld he seam pololei.Hoʻohana ke kuʻekuʻe kūʻē i ke ʻano hana kuʻi ʻana me ka ʻole o ka metala hoʻopiha.ʻAʻohe hoʻopiha o nā mea ʻē aʻe i ka weld seam.ʻO ka hopena o ka ʻili a me ka hopena pili o ka manawa kiʻekiʻe e hoʻomehana koke i ka lihi o ka pā i ka wela welding, a ua hoʻokumu ʻia ka forging ma ke kaomi ʻana i ka extrusion roller.wili lole.
Hiki ke hoʻokaʻawale ʻia ka paipu kila kūʻē kūʻē i ʻelua mau ʻāpana: kiʻekiʻe alapine kūʻē kūʻē HFW (High frequency welded pipe) a me ka haʻahaʻa haʻahaʻa haʻahaʻa kūwaho LFW (Low frequency welding).
Hoʻohana nui ʻia nā paipu kila ERW e lawe i ka mahu a me nā mea wai e like me ka aila a me ke kinoea maoli, a hiki ke hoʻokō i nā koi like ʻole o ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.I kēia manawa, noho lākou i kahi kūlana koʻikoʻi ma ke kahua o nā paipu kaʻa i ka honua.
2. Piula kila wiliwili ʻia
ʻO ka paipu kila wiliwili ʻia, ka inoa Pelekane SSAW (Spiral submerged-arc welding pipe), ʻo ke ʻano weld he spiral seam.Hoʻohana ʻia ke ʻano o ka hoʻoheheʻe ʻana i ke arc submerged, a hoʻopaʻa ʻia nā papa ʻelua o loko a me waho.ʻO ka hoʻoheheʻe ʻana i ka arc submerged (me ka hoʻoheheʻe ʻana i ka arc submerged a me ka electroslag surfacing, etc.) he ʻano hana kuʻihao koʻikoʻi, nona nā mea maikaʻi o ka maikaʻi kuʻihao paʻa, kiʻekiʻe o ka wiliwili ʻana, ʻaʻohe kukui arc a me ka uahi liʻiliʻi a me ka lepo.
ʻO ka paipu welded spiral he anawaena nui, hiki ke piʻi aku ma mua o 3000mm, a ʻoi aku ka kūpono no ka lawe ʻana i ka pipeline nui-diameter a me nā hale kūkulu.
ʻEkolu, paipu kila wili wili pololei
ʻO Longitudinally Submerged Arc Welded Pipe, ʻo ka inoa Pelekane ʻo LSAW (Longitudinally Submerged Arc Welded Pipe), a ʻo ke ʻano weld he seam pololei.Hoʻohana pū ʻia ke ʻano o ka hoʻoheheʻe ʻana i ka arc submerged, a hoʻopaʻa ʻia nā papa ʻelua o loko a me waho.ʻO ka mānoanoa o ka pā o ka paipu kila humuhumu pololei he ʻano nui, a ua like kona hoʻohana ʻana me ka paipu kila welded spiral.
E like me nā kaʻina hana like ʻole, hiki ke hoʻokaʻawale ʻia nā paipu kila i hoʻopaʻa ʻia i ʻelua mau ʻāpana: UOE (Uing a me Oing forming pipe) a me JCOE (J-ing, C-ing a me O-ing pipe).ʻO ke ʻano hana UOE (Hoʻokumu ʻia ʻo U, hoʻokumu ʻO, hoʻonui ʻia E anawaena), ke ʻano hana JCOE (paʻi ʻia ka pā kila i ke ʻano J, a laila kaomi i ke ʻano C a me ke ʻano O i ka huli ʻana, a laila hoʻonui ʻia).
Pono e hoʻomaopopo ʻia ʻo ka submerged arc welding process (SAW) he ʻano hoʻohui uila (EFW Electric Fusion Welded Pipe), ʻo ia ka hoʻohui ʻana i nā metala ma ka hoʻomehana ʻana i ka metala ma waena o hoʻokahi a i ʻole kekahi mau electrodes consumable a me ka mea hana.ʻO kekahi o nā kaʻina hana e hoʻoheheʻe piha ai ka arc i ka metala a me ka mea hoʻopihapiha me ka ʻole o ke kaomi, a hele mai ka ʻāpana metala hoʻopiha mai nā electrodes.
