ʻOkoʻa ma waena o Spiral Steel Pipe a me LSAW Steel Pipe

Paipu kila SpiralaPaipu kila LSAWʻelua ʻano maʻamau opaipu kila welded, a aia kekahi mau ʻokoʻa i kā lākou hana hana, nā hiʻohiʻona hana, ka hana a me ka noi.

Kaʻina hana
1. paipu SSAW:
Hana ʻia ia e ka ʻōwili ʻana i ke kila a i ʻole ka pā kila i loko o kahi paipu e like me kahi kihi spiral a laila welded.
He spiral ka weld seam, i māhele ʻia i ʻelua ʻano hana kuʻi: ʻelua ʻaoʻao submerged arc welding a me ke kiʻekiʻe-frequency welding.
Hiki ke hoʻololi ʻia ke kaʻina hana ʻana i ka laula a me ke kihi helix, e hoʻomaʻamaʻa i ka hana ʻana o ka paipu kila nui.

 

2. Paipu LSAW:
Hoʻopio pololei ʻia ke kila kila a i ʻole ka pā kila i loko o kahi paipu a laila wili ʻia ma ka ʻaoʻao longitudinal o ka paipu.
Hoʻokaʻawale ʻia ka weld ma kahi laina pololei ma ka ʻaoʻao longitudinal o ke kino paipu, me ka hoʻohana pinepine ʻana i ke kuʻekuʻe kūʻē kiʻekiʻe a i ʻole ka hoʻoheheʻe ʻana i ke arc submerged.

He mea maʻalahi ke kaʻina hana, akā ua kaupalena ʻia ke anawaena e ka laulā o ka mea maka.
No laila ua nāwaliwali ka mana o ka paipu kila LSAW, ʻoiai ʻoi aku ka ikaika o ka puʻu kila spiral.
Nā kikoʻī
1. Paipu kila wiliwili:
He kūpono ia no ka hana ʻana i ka paipu kila nui-caliber, pā mānoanoa.
ʻO ke anawaena maʻamau ma waena o 219mm-3620mm, a ʻo ka mānoanoa o ka pā he 5mm-26mm.
hiki ke hoʻohana i ke kila ʻoi aku ka liʻiliʻi e hana i ka paipu anawaena ākea.

2. LSAW kila paipu:
He kūpono no ka hana ʻana i ke anawaena liʻiliʻi, ka paipu kila me ka lahilahi lahilahi.
ʻO ke anawaena maʻamau ma waena o 15mm-1500mm, a ʻo ka mānoanoa o ka pā he 1mm-30mm.
ʻO ka kikoʻī huahana o ka paipu kila LSAW he liʻiliʻi ke anawaena, ʻoiai ʻo ka kikoʻī huahana o ka paipu kila spiral he nui ke anawaena. ʻO ka mea nui kēia ma muli o ke kaʻina hana o ka paipu kila LSAW e hoʻoholo ai i kona ʻano liʻiliʻi liʻiliʻi liʻiliʻi, ʻoiai hiki ke hoʻoponopono ʻia ka paipu kila spiral ma o nā ʻāpana wiliwili spiral e hana i nā kikoʻī like ʻole o ka huahana. No laila, ʻoi aku ka maikaʻi o ka paipu kila spiral inā makemake ʻia ka paipu kila nui, e like me ka ʻenehana mālama mālama wai.
Ka ikaika a me ke kūpaʻa
1. Paipu kila wiliwili:
Hoʻokaʻawale ʻia nā seams welded, hiki ke hoʻopuehu i ke koʻikoʻi ma ke kuhikuhi axial o ka pipeline, a no laila ua ʻoi aku ka ikaika o ke kūʻē ʻana i ke kaomi o waho a me ka deformation.
ʻOi aku ka paʻa o ka hana ma lalo o nā kūlana koʻikoʻi like ʻole, kahi kūpono no nā papahana kaʻa kaʻa lōʻihi. 2.

2. Piula kila humu pololei:
Hoʻopaʻa ʻia nā hili welded i kahi laina pololei, ʻaʻole like ka puʻupuʻu koʻikoʻi e like me ka paipu kila spiral.
He haʻahaʻa haʻahaʻa ka pale kuʻi ʻana a me ka ikaika holoʻokoʻa, akā ma muli o ka wili wili pōkole, ʻoi aku ka maʻalahi o ka maikaʻi wili.
Koina
1. Paipu kila wiliwili:
ʻO ke kaʻina hana paʻakikī, lōʻihi wiliwili wili, kiʻekiʻe wili a me ka hoʻāʻo koina.
He kūpono no ka hana ʻana i nā paipu anawaena nui, ʻoi aku ka maikaʻi o ka nui o ka laula o ke kaula kila. 2.

2. LSAW kila paipu:
ʻO ke kaʻina hana maʻalahi, kiʻekiʻe ka hana pono, pōkole weld seam a maʻalahi ke ʻike, haʻahaʻa i ke kumukūʻai hana.
He kūpono no ka hana nui ʻana o ka paipu kila liʻiliʻi.

 

Weld seam kino
ʻO ke kuʻi weld o ka paipu kila LSAW he pololei, aʻo ka hili ʻana o ka paipu kila spiral he spiral.
ʻO ke kuʻi kuʻi pololei ʻana o ka paipu kila LSAW e liʻiliʻi i kona pale ʻana i ka wai, he mea maikaʻi ia no ka lawe ʻana i ka wai, akā i ka manawa like, hiki ke alakaʻi i ke koʻikoʻi i ka weld seam, e pili ana i ka hana holoʻokoʻa. ʻOi aku ka maikaʻi o ka hoʻopaʻa ʻana o ka spiral weld seam o ka spiral steel pipe, hiki ke pale pono i ka leakage o ka wai, ke kinoea a me nā media ʻē aʻe.
