ʻO ka ʻokoʻa nui ma waena o nā paipu welded ʻelua o ka paipu wiliwili spiral a me ka paipu wili pololei ʻo ia ka ʻokoʻa i ke ʻano kuʻi.

ʻO ka paipu i hoʻoheheʻe ʻia he haʻahaʻa carbon carbon structural steel a i ʻole kahi ʻāpana kila haʻahaʻa i ʻōwili ʻia i loko o kahi pahu hakahaka me kahi kihi helix (i kapa ʻia hoʻi i kapa ʻia ka angle), a laila wili ʻia a hana ʻia i kahi hui paipu, hiki ke hoʻohana i kahi ʻāpana haiki. kila Ka hana ʻana o nā paipu kila ke anawaena nui.ʻO ka pipe welded spiral ka nui o ka spiral submerged arc welded pipe (SSAW), i hoʻohana pinepine ʻia i ke kūkulu ʻana i nā paipu kinoea like ʻole ma Kina.Hōʻike ʻia kāna mau kikoʻī e "ka anawaena o waho * ka mānoanoa pā".ʻO nā paipu i hoʻopaʻa ʻia i ka ʻaoʻao hoʻokahi a me nā ʻaoʻao ʻelua.ʻO ka paipu welded e hōʻoia i ka hoʻāʻo hydraulic a me ka ikaika tensile a me ka hoʻoheheʻe anu anuanu o ka weld e like me nā lula.

ʻO ka paipu wili wili pololei he alapine kiʻekiʻe a me kahi hopena hopena kokoke e hana ʻia e ka papa solder ma mua o ka hoʻokumu ʻia ʻana o ke kuʻi ʻana e ka mīkini hoʻoheheʻe ʻia, a ua wela a hoʻoheheʻe ʻia ka ʻaoʻao o ka pahu pahu. malalo o kekahi ikaika kaomi, hooluu hooluu.Hoʻohana ʻia ka paipu wili wili pololei kiʻekiʻe kahi e hoʻoheheʻe ʻia ai ka lihi o ka paipu blank e ke alapine kiʻekiʻe (ERW), i kapa ʻia ʻo ka seam submerged arc welded pipe (LSAW) ma o ka hoʻoheheʻe ʻana me kahi arc uila.

ʻOi aku ka ikaika o ka paipu wiliwili spiral ma mua o ka paipu wili pololei.ʻO ke kaʻina hana nui ʻo ia ka wiliwili arc submerged.Hiki i ka paipu wiliwili spiral ke hana i nā paipu wili me nā anawaena paipu like ʻole me ka laulā like o nā blanks, a hiki nō hoʻi ke hana i nā paipu welded me nā anawaena nui aʻe me nā hakahaka haiki.

He mea maʻalahi ke kaʻina hana o ke kaʻina hana o ka paipu wili pololei, ka mea nui i ka hana ʻana, i māhele ʻia i kiʻekiʻe-frequency welded straight seam welded pipe a submerged arc welded straight welded pipe.He kiʻekiʻe ka hana ʻana o ka paipu wili wili pololei, ke kumu kūʻai haʻahaʻa a me ka hoʻomohala wikiwiki.

Eia naʻe, ke hoʻohālikelike ʻia me ka paipu wili pololei o ka lōʻihi like, ua hoʻonui ʻia ka lōʻihi weld e 30 a 100, a ua haʻahaʻa ka wikiwiki o ka hana.No laila, ʻo nā paipu wiliwili liʻiliʻi liʻiliʻi, ua wili ʻia ka nui o nā paipu wili pololei, ʻoiai ʻo nā paipu wiliwili anawaena nui ka nui o ka wili ʻia.
