ʻO ka paipu kila LSAW i hoʻopaʻa ʻia me ka longitudinally submerged arc
LSAW (Papa nui i hoʻopaʻa ʻia i loko o ke arc welded pipe)hana ʻia ma ka hoʻohana ʻana i ka pā ma waena o ka mānoanoa ma ke ʻano he mea maka, a kaomi ʻana (ka ʻōwili) i ka pā kila i loko o kahi pahu hakahaka i loko o kahi mold a i ʻole ka mīkini hoʻoheheʻe ʻia, e hoʻohana ana i ke ʻano hoʻoheheʻe arc submerged ʻaoʻao ʻelua a hoʻonui i ke anawaena.ʻO ka laulā kikoʻī o kāna huahana he ākea, maikaʻi ka paʻakikī, ka plasticity, ka kūlike a me ka compactness o ka weld seam.Loaʻa iā ia nā mea maikaʻi o ka nui anawaena, mānoanoa pā mānoanoa, kiʻekiʻe puʻe kū'ē, haʻahaʻa wela kū'ē a me ka ikaika corrosion kū'ē.I ka wā e kūkulu ai i ka ikaika kiʻekiʻe, kiʻekiʻe-ʻoʻoleʻa, kiʻekiʻe kiʻekiʻe ka lōʻihi o ka ʻaila a me nā paipu kinoea, ʻo ka hapa nui o nā paipu kila i makemake ʻia he mau paipu LSAW pā nui-caliber mānoanoa.
LSAW (Longitudinal double submerge arc welding) paipu kila kalaponahe ʻano paipu SAW i hana ʻia me nā pā kila i ʻōwili wela ʻia e JCOE a i ʻole UOE hana ʻenehana.
Hoʻohana ʻia ka paipu LSAW no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa a i ʻole ka petroleum kiʻekiʻe a i ʻole ke kinoea kūlohelohe no ka halihali lōʻihi a hiki ke hoʻohana nui ʻia i nā kākoʻo a i ʻole nā kumu.
Ma muli o kona pono o ka hilinaʻi kiʻekiʻe a me ka hana palekana, ua hoʻohana nui ʻia ka paipu LSAW i nā ʻenehana pipeline a me ke kūkulu ʻana, ʻoiai ma lalo o ke kūlana koʻikoʻi loa, a hiki ke hoʻohana ʻia i ka ʻenekinia o ka ʻoihana kemika, ka mana uila, ka irrigation, ke kūkulu ʻana a me ka piling. etc. Ka pono o ka paipu LSAW no ka aila a me ke kinoea paipu: e hana i oi aku ka manoanoa paia o na paipu, max i 120mm.
Nā hiʻohiʻona: ʻO nā paipu kila ke anawaena nui, Nā paia mānoanoa, Kūʻē kiʻekiʻe.
