Ka Hana Hana oASTM A252 LSAW Paipu kila:

Hoʻohana ʻo Longitudinal Submerged-arc Welded(LSAW) Pipe i ka ʻenehana hoʻoheheʻe arc submerged, me ka hoʻohana ʻana i ka hoʻopiha piha ʻana, ka pale ʻana i ka ʻōpala i kanu ʻia.

ʻO LSAW ka ʻōlelo Pelekane o ka submerged arc welded straight seam steel pipe.ʻO ke kaʻina hana o ke arc i hoʻoheheʻe ʻia i loko o ka paipu kila wili pololei me ka ʻenehana hana JCOE, ka ʻenehana hoʻoheheʻe ʻana i ka arc submerged a me ka ʻenehana hana UOE.
