Paipu Weled Steel Carbon
Hoʻokumu ʻia ka paipu butt-welded ma ka hānai ʻana i kahi pā kila wela ma o nā mea hoʻoheheʻe e ʻōwili ai i loko o kahi ʻano pōʻai pōʻai.ʻO ka ʻomi ikaika ʻana i nā ʻaoʻao ʻelua o ka pā e loaʻa ai kahi hui hui a i ʻole ka humuhumu.Hōʻike ke kiʻi 2.2 i ka pā kila i kona hoʻomaka ʻana i ke kaʻina hana o ka hana ʻana i ka paipu i hoʻopili ʻia
ʻO ka mea maʻamau o nā ʻano ʻekolu, ʻo ia ka paipu spiral-welded.Hoʻokumu ʻia ka paipu spiral-welded e ka wili ʻana i nā ʻāpana metala i ke ʻano ʻano spiral, e like me ka mea ʻoki's kia, a laila wili i kahi e hui ai nā ʻaoʻao i kahi humuhumu.Hoʻopili ʻia kēia ʻano paipu i nā ʻōnaehana paipu me ka haʻahaʻa haʻahaʻa ma muli o kona mau paia lahilahi.Hōʻike ke kiʻi 2.3 i ka paipu wiliwili ʻia e like me ka mea i ʻike ʻia ma mua o ka wili ʻana.
Loaʻa i kēlā me kēia o nā ʻano ʻekolu no ka hana ʻana i ka paipu kona mau pono a me nā hemahema.No ka laʻana, hoʻokumu ʻia ka paipu butt-welded mai ka pā i ʻōwili ʻia i ʻoi aku ka mānoanoa o ka paia a hiki ke nānā ʻia no nā hemahema ma mua o ka hana ʻana a me ka wili.He mea maikaʻi loa kēia hana hana inā makemake ʻia nā paia lahilahi a me nā lōʻihi lōʻihi.Ma muli o ke kaʻina welded, akā naʻe, loaʻa mau nā hemahema i pakele i ka nui o nā loiloi mana maikaʻi i hana ʻia i ka wā hana.
ʻO ka hopena, ua kūkulu ka American National Standards Institute (ANSI) i nā alakaʻi koʻikoʻi no ka hana ʻana i ka paipu.Ua kākau ʻia ʻo Pressure Piping Code B31 e hoʻokele i ka hana ʻana i ka paipu.ʻO ka mea nui, hāʻawi ka code B31.1.0 i kahi kumu ikaika o 85% no ka paipu i ʻōwili ʻia, 60% no ka paipu spiral-welded, a me 100% pono no ka paipu seamless.
ʻO ka maʻamau, hana ʻia nā mānoanoa pā ākea e ke ʻano seamless.Eia nō naʻe, no ka hoʻohana ʻana i ka paipu haʻahaʻa haʻahaʻa, ʻo ke ʻano welded hoʻomau ka ʻoi aku ka waiwai.Hana ʻia ka paipu seamless ma ka lōʻihi hoʻokahi a pālua.ʻOkoʻa ka lōʻihi like ʻole mai ka 16'-0″i ka 20'-0″.Paipu 2″a ma lalo iho i loaʻa i nā lōʻihi pālua ʻelua e ana ana mai ka 35'-0″i 40'-0″.
