Hoʻohana nui ʻia nā huahana stainless steel i nā ʻoihana a me nā noi ma muli o kā lākou hana maikaʻi loa a me nā waiwai. I kēia lā, mākou e kūkākūkā kuhiliʻole kila seamless paipu a me ERW kuhiliʻole kila paipu, a me ka likeʻole ma waena o nā huahana elua.
Aia kekahi mau ʻokoʻa ma waena o ka paipu kila kuhiliʻole ERW a me ka paipu kuhili ʻole. He pōkole ʻo ERW Pipe no Electric Resistance Welding. Hoʻohana ʻia ia e lawe i nā wai e like me nā wahie, nā kinoea, a me nā mea ʻē aʻe, me ka nānā ʻole i ke kaomi, a he hana koʻikoʻi i nā pipeline a puni ka honua. I ka manawa like, he paipu kila ʻole. Hoʻohana ʻia nā paipu kila square a me ka rectangular me ka ʻole o nā hono a me nā profile hollow no ka lawe ʻana i nā wai ma muli o ko lākou kūlana kiʻekiʻe kiʻekiʻe a me ka torsion ikaika, a me ka hana ʻana i nā ʻāpana a me nā ʻāpana mechanical. Ma keʻano laulā, hoʻohana ʻia nā paipu ERW a me nā paipu kila ʻole no nā kumu like ʻole.
Hana ʻia nā paipu kila kuhili ʻole mai nā bilets poepoe, aʻo nā paipu kila kuhili ʻole ERW i hana ʻia mai nā ʻōwili wela. ʻOiai he ʻokoʻa loa nā mea maka ʻelua, pono e hoʻomaopopo ʻia ʻo ka maikaʻi o ka huahana hope - pili pono nā paipu i kēia mau mea ʻelua - ka mana o ka maikaʻi i ka wā o ka hana ʻana a me ke kūlana mua a me ka maikaʻi o nā mea maka. Hana ʻia nā paipu ʻelua me ke kila kila o nā ʻano like ʻole, akā ʻo ka mea maʻamau he paipu i hana ʻia me ke kila kila 304.
Hoʻomaʻamaʻa ʻia ka billet poepoe a hoʻokuʻu ʻia ma luna o ke koʻokoʻo ʻāwī a hiki i kona ʻano puha. A laila, mālama ʻia ko lākou lōʻihi a me ka mānoanoa e nā ʻano extrusion. Ma keʻano o ka hanaʻana i nā paipu ERW, heʻokoʻa loa ke kaʻina hana. Hoʻopiʻi ʻia ka ʻōwili ma ka ʻaoʻao axial, a hoʻopaʻa ʻia nā kihi converging ma kona lōʻihi holoʻokoʻa e ke kuʻi ʻana.
Ua hui piha ʻia nā paipu kila kila ʻole ma ka laina hui a loaʻa iā OD a hiki i 26 iniha. Ma ka ʻaoʻao ʻē aʻe, ʻo nā hui kila kiʻekiʻe loa me ka ʻenehana ERW hiki ke hoʻokō i kahi anawaena o waho o 24 iniha.
No ka mea, hoʻokuʻu ʻia nā paipu seamless, ʻaʻohe o lākou mau hono ma ke ʻano axial a i ʻole radial. ʻO nā paipu ERW, ma ka ʻaoʻao ʻē aʻe, ua hana ʻia e ka hoʻowili ʻana i nā wili ma ko lākou axis waena no laila e wili ʻia lākou ma ko lākou lōʻihi holoʻokoʻa.
ʻO ka maʻamau, hoʻohana ʻia nā paipu seamless no nā noi kaomi kiʻekiʻe, aʻo nā paipu ERW e hoʻohana ʻia no ka lawelawe ʻana ma nā wahi haʻahaʻa a me waena.
Eia kekahi, hāʻawi ʻia i nā hiʻohiʻona palekana o nā paipu seamless, hoʻohana nui ʻia lākou i ka aila a me ke kinoea, ka hoʻomaʻemaʻe aila a me nā ʻoihana kemika ʻē aʻe, a pono ke kulekele no-leakage e hōʻoia i ka palekana o nā kānaka a me nā ʻoihana. Ma ka manawa like, hiki ke hoʻohana ʻia nā paipu ERW i hana maikaʻi ʻia ma lalo o ka mana koʻikoʻi no nā lawelawe like ʻole ma mua o nā lawelawe maʻamau e like me ka lawe ʻana i ka wai, scaffolding a me ka pā.
Ua ʻike ʻia ʻo ka hoʻopau ʻana i loko o nā paipu ERW e hoʻomalu mau ʻia e nā ʻano mana maikaʻi maikaʻi, no laila ʻoi aku ka maikaʻi ma mua o nā paipu seamless.
I ka hihia o ASTM A53, ʻo ke ʻano S ʻo ia hoʻi ke ʻano ʻole. ʻAno F - umu ahi, akā wili, ʻano E - kūʻē kūʻē. ʻo ia wale nō. ʻO kēia ke ala maʻalahi e hoʻoholo ai inā ʻaʻohe paipu a i ʻole ERW.
Manaʻo kōkua: ʻoi aku ka kaulana o ASTM A53 Grade B ma mua o nā māka ʻē aʻe. Hiki ke waiho wale ʻia kēia mau paipu me ka ʻole o ka uhi ʻia, a i ʻole hiki ke galvanized a i ʻole ka wela wela a hana ʻia me ka hoʻohana ʻana i ke kaʻina hana welded a i ʻole. I ka ʻāpana aila a me ke kinoea, hoʻohana ʻia nā paipu A53 no ka hoʻolālā ʻana a me nā noi koʻikoʻi ʻole.
Inā makemake ʻoe i ʻike hou aʻe e pili ana i kēia papahana, e ʻoluʻolu e kelepona mai iā mākou no ke kūlana o kēia manawa, ka ʻike pili hui papahana, etc.
