kila paipuhoʻomaka ka hoʻomohala ʻenehana hana me ka hoʻonui ʻana o ka hana ʻana i ka paikikala, ka hoʻomohala ʻana i ka aila i loko o ka hoʻomaka ʻana o ke kenekulia 19, ʻelua mau moku kaua honua, boilers, hana mokulele, ma hope o ke kaua lua thermal power boiler manufacturing, ʻoihana a no laila ka hoʻomohala ʻana o ka ʻaila a me ke kinoea. ka lawe ʻana, hoʻokele maikaʻi i ka ʻoihana paipu kila i loko o ka hoʻomohala ʻana i nā ʻano, hua a me ka maikaʻi. ʻO ka maʻamau o ka paipu kila ma ka laina me ke ʻano o ka ʻaha hui, māhele ʻia i ka paipu kila seamless a me ka paipu kila welded ʻelua ʻano, i kēia manawa e hoʻolauna i ka paipu kila welded.
Welded kila paipu 'o ia ka welded kila paipu, kona hana 'ana i ka paipu blank (paa kila a me ke kāʻei kila) me ka laha o ka hana 'ana e kulou a olokaa i loko o ka makemake cross-sectional shape a me ka nui o ka paipu paipu, a pela aku. e hoʻohana i nā ʻano kuʻikuʻi like ʻole e weld i ka weld a loaʻa ke kaʻina hana paipu kila. Ke hoʻohālikelike ʻia me ka paipu kila maʻemaʻe, ʻo ka paipu welded i nā hiʻohiʻona o ka precision kiʻekiʻe, ʻoi aku ka pololei o ka mānoanoa o ka pā, nā mea hana maʻalahi, nā hana liʻiliʻi, ka hana mau ʻana i ka hana, ka hana maʻalahi, ka laulā huahana o ka ʻāpana a laila.
E māhele ʻia ke kaʻina hana no nā paipu i: SSAW (Spirally Submerged Arc Welding); LSAW (Longitudinous Arc Welding); pale uila Welding (RW) ʻekolu.
I. 'o ke ka'ina hana o ka paipu kila spiral e like me keia
● ʻO nā mea maka o ka paipu kila spiral he strip coil, welding wire a me ka flux.
● Ma mua o ka hana ʻana i ka ʻili ma hope o ka pae ʻana, ʻokiʻoki, hoʻolālā, hoʻomaʻemaʻe i ka ʻili, ka lawe ʻana a me ka hana ʻana.
● Hoʻohana ʻia ka weld gap control device e hōʻoia i ka hoʻokō ʻana o ka weld gap i nā koi kuʻi, a me ke anawaena paipu, ka ʻaoʻao staggered a me ka weld gap ua hoʻomalu pono ʻia.
● Ma hope o ka ʻoki ʻana i hoʻokahi paipu kila, ʻo kēlā me kēia pūʻulu o ke poʻo o ke kila paipu ʻekolu e hoʻopaʻa i ka ʻōnaehana nānā mua, e nānā i nā waiwai mechanical o ka weld, haku mele, hoʻoheheʻe kūlana, maikaʻi o ka paipu kila a ma hope o ka nānā ʻole ʻana, e hōʻoia i ka paipu. ka hana kūpono, hoʻokomo ʻia i loko o ka hana.
ʻElua, paipu hoʻoheheʻe arc i hoʻopaʻa ʻia
Hoʻohana maʻamau ʻo Straight seam submerged arc welded pipe (LSAW) i ka pā ma ke ʻano he mea, ma o nā kaʻina hana like ʻole, hoʻohana i ka wiliwili arc submerged ʻaoʻao ʻelua a me ka hoʻonui post-weld a me nā hana ʻē aʻe e hana ai i ka paipu welded.
ʻO ka mea nui ka mīkini hoʻoheheʻe ʻana, ka mīkini pre - bending machine, ka mīkini hana, ka mīkini pre - welding, ka mīkini hoʻonui a laila. I kēia manawa, aia nā UO (UOE), RB (RBE), JCO (JCOE) a laila. ʻO ka pā i loko o ka mea hoʻoheheʻe ʻia e kaomi mua ʻia i ke ʻano U, no laila kaomi ʻia i loko o ke ʻano O, a no laila ka hoʻoheheʻe ʻana i loko a me waho o ka arc submerged, wili maʻamau ma luna a i ʻole ka lōʻihi piha o ka hoʻonui (Expanding) i kapa ʻia ʻo UOE welded pipe, ʻaʻole. Hoʻonui i kapa ʻia ʻo UO welded pipe. ʻOlokaʻa ʻia ka pā ma ke ʻano he kuʻekuʻe, a laila hoʻokō ʻia ka hoʻoheheʻe ʻana i loko a me waho. Ma hope o ke kuʻi ʻana, ʻo ke anawaena ʻo RBE welded tube a i ʻole RB welded tube me ka ʻole e hoʻonui. Hoʻokumu ʻia ka pā i loko o ke kauoha o JcO-type, a ma hope o ke kuʻi ʻana, hoʻonui ʻia ke anawaena i ka paipu welded JCOE a i ʻole JCO welded pipe me ka ʻole o ka hoʻonui ʻana.
ʻEkolu, humuhumu pololei kiʻekiʻe alapine welded paipu (ERW) ʻo ia ka ʻōwili wela ma hope o ka hoʻoheheʻe ʻana i ka mīkini, me ka hoʻohana ʻana i ke ʻano uila a me ka hopena pili o ke alapine kiʻekiʻe o kēia manawa, no laila e wela a hoʻoheheʻe ʻia ke kuʻi o ka paipu, ma lalo o ka hana o ka extrusion. wiliwili puʻupuʻu e loaʻa ai ka hana.
