Paipu ERWnā manaʻolana hoʻomohala a me nā pilikia e kū nei

ʻO ka hoʻopaʻapaʻa kū'ē he pōkole o ka paipu kila ERW me ka nui o nā pono, e like me ka huahana kiʻekiʻe, ke kumukūʻai haʻahaʻa, ka pololei dimensional maikaʻi, ka helehelena nani.Eia naʻe, i ka wā ma mua, ma muli o ka hilinaʻi maikaʻi ʻole o ka weld, nā palena nui i ka hoʻohana.ʻO ka hapa o ka hana paipu liʻiliʻi.

ʻO ka mīkini hoʻoheheʻe paipu kila ERW i hana i nā hoʻokō hauʻoli, a ʻo kēia kumumanaʻo he alakaʻi e hoʻonui ai.ʻO ka ʻenehana hoʻomalu aunoa e hoʻonui i nā ʻāpana i hāʻawi ʻia e hōʻoia i ka maikaʻi o ka weld i hoʻomaikaʻi nui ʻia;ma muli o ka hoʻomaikaʻi ʻana o ka ʻenehana ʻike kani ultrasonic, hiki ke hoʻokō ʻia ka ʻike ʻana o ka flaw ultrasonic Wong stack trace detection i ka laina hana;ma muli o ka hoʻomaikaʻi ʻana i ka pae o ka automation.ʻO ka annealing o ka weld (normalizing) kaʻina lapaʻau i ka laina hana.ʻO ka hoʻomaikaʻi ʻana i ka hana weld.

Ma luna o kekahi mau ʻenehana noiʻi, hoʻomaikaʻi nui i ka hilinaʻi o nā welds paipu kila ERW.Ke hoʻonui nei i ka laulā o nā noi.I kēia manawa, hiki ke hoʻohana ʻia kekahi o ka honua o ka ERW steel pipes pipe plant ma nā wahi anu, a ua kūkulu nā ʻāina he nui i ka laina hana paipu ERW.

Mai nā ʻāina ʻo ERW paipu hana, ma ka hoʻohui ʻana i ka huahana kiʻekiʻe ma mua, haʻahaʻa i ka ʻoki ʻana, ka pololei dimensional mai waho, ka ikaika tensile o ka weld.ʻO ka elongation a me ka hoʻohaʻahaʻa ʻana, ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i ke ana wela o ka lumi e hiki ke hoʻokō i nā koi kikoʻī.Akā, he nui na mea hana o ERW kila paipu welds ilihune haʻahaʻa wela toughness, i kaupalena 'ia ko lakou hoʻohana ma ke anu.

ʻO ka nui o ka hoʻokomo wela, ka wikiwiki o ka welding, ka convergence angle a me nā mea ʻē aʻe e pili ana i ka haʻahaʻa haʻahaʻa haʻahaʻa o ka weld, ua hana ʻia ka nui o nā hana pono ma kēia ʻano.Weld ma nāʻaoʻaoʻelua o ka welding ili wikiwiki e kokoke i kekahi i kekahi i loko o ke kaʻina hana, anu welding, a weld elua, ma muli o ka metala hehee ua ninini i ka ili kaawale ka māmā holo, e like me ka mua ka māmā holo ina ka hope ka mämä holo. nui e oi haole komohewa FATT waiwai mahuahua, ka palapala paipai convergence kihi o 5 i 6. Oi aku ka welding māmā holo i 20m/min kiko'ī kūlana kiko'ī ana kālailai, au manaʻoʻiʻo ma hope o kekahi mau ho'āʻo e loaʻa i ka maikaʻi loa kuʻihao kaʻina, pela hoʻomaikaʻi i ka haʻahaʻa wela toughness. o ka weld.
