| •ʻO nā paipu Buttweld he mau paipu paipu i hoʻohana ʻia e hoʻololi i ke ala o kahi paipu (kuʻekuʻe), hoʻemi / hoʻonui i ka nui o ka paipu (mea hoʻemi), lālā (tees, cross) a i ʻole makapō i kahi paipu (butt weld cap) | |
| • Loaʻa nā lako Buttweld i nā ʻano like ʻole (nā kuʻekuʻe, nā tees, nā mea hoʻemi, nā keʻa, nā pāpale, nā stub ends), nā māka waiwai (carbon, high-yield carbon, low-alloy, stainless, duplex, a me nickel alloys). | |
| a me nā ana (2 a 24 'īniha i ka hoʻokō ʻole ʻia, a wili ʻia no nā nui paipu nui). | |
| •ʻO nā kikoʻī koʻikoʻi no ka buttweld fittings ʻo ia ka ASME B16.9 (carbon and alloy fittings) a me MSS SP 43 (e hoʻohui i ka ASME B16.9 no nā mea kila kila, duplex, a me nickel alloy BW fittings). | |
| •E like me ke kūʻai ʻia ʻana o ka paipu mai ka Hōʻike 10 a i ka Hōʻike 160, kūʻai ʻia nā mea hoʻohui paipu butt weld i ke ala like. | |
| ʻOi aku ka maʻamau o nā mea welded butt weld i ke kila kila ma muli o ke kumu kūʻai. ʻOi aku ka maʻamau o Sch 10S, SCH40S SS i nā mea hoʻoheheʻe kila kila. | |
| ʻO nā mea maʻamau no nā mea hoʻopili kuʻekuʻe he A234 WPB (A & C pū kekahi), High Yield Carbon Steel, Stainless Steel 304 a me 316 a me Nickel Alloys. | |
| • ʻO nā paipu paipu welo i loko o ke kila kalapona a me ke kila kuhiliʻole nā ʻāpana hui e hiki ai i ka hui ʻana o nā kiwikā, | |
| nā paipu a me nā mea hana ma luna o ka ʻōnaehana paipu. Hoʻomaikaʻi nā mea welded i nā flanges paipu i kēlā me kēia ʻōnaehana paipu a hiki ke: | |
| 1. E hoʻololi i ka ʻaoʻao o ke kahe i loko o kahi ʻōnaehana paipu | |
| 2. Hoʻohui a hui pū paha i nā paipu a me nā mea hana | |
| 3. Hāʻawi i nā lālā, ke komo a me ka lawe ʻana no nā mea kōkua | |
Nā Pepa ʻenehana
| ʻO nā mea hoʻopaʻa hoʻoheheʻe ʻia ʻana: |
| Loaʻa nā pono kīwī kuʻi ʻole ma 316 a me 304 mau māka. |

| Huina Kemika% |
| Nā Koina Tensile |
| Ikaika U'i: (KSI) = 60 |
| Ka ikaika o ka hua: (KSI) = 35 |
| (Hoʻololi ʻo KSI i MPA {Megapascals} ma ka hoʻonui ʻana me 6.895) |

| (Hoʻololi ʻo KSI i MPA {Megapascals} ma ka hoʻonui ʻana me 6.895) | |
| Nā Pōmaikaʻi o nā Paipu Weld Butt Weld | |
| Hāʻawi ka pilina welded i kahi pilina paʻa | |
| Hoʻohui ka hoʻolālā metala mau i ka ikaika o ka ʻōnaehana paipu | |
| ʻO nā lako Buttweld me nā papa hoʻonohonoho paipu kūpono, hāʻawi i ke kahe holo ʻole i loko o ka paipu. ʻO kahi weld komo piha a hoʻokomo pono ʻia ʻo LR 90 Elbow, Reducer, Concentric reducer etc. | |
| ʻO ke koho o nā radius huli like ʻole me ka hoʻohana ʻana i ka Radius Short (SR), Long Radius (LR) a i ʻole 3R Elbows | |
| Hoʻohālikelike ʻia ke kumu kūʻai me kā lākou mau ʻāpana kūʻai wili a i ʻole socket weld counter | |
| Loaʻa nō hoʻi nā lako Welded Steel ma SCH 10, e ʻae ana i kahi koho pā ʻoi aku ka lahilahi | |
| ʻOi aku ka maʻamau o nā Kuleana Kūleʻa Kūleʻa Kūleʻa ma SCH 10 a me SCH 40 | |
| Ninau a pane | |
| Nīnau: Nīnau ka mea kūʻai aku i nā mea hoʻoheheʻe weld ma A105: | |
| A: ʻO A234WPB ka mea hoʻopili ʻana i ke kila kalapona maʻamau. Ua like ia me A105 flanges, akā naʻe, ʻaʻohe mea e like me ka A105 a i ʻole A106 butt weld fitting. | |
| ʻO A106 Gr.B no ka pae paipu. Hana ʻia nā mea pono A234WPB mai nā paipu A106GR.B. ʻO A105 kahi mea mai ka Bar i hoʻopaʻa ʻia e lilo i kiʻekiʻe kiʻekiʻe a i ʻole Flange | |
| Nīnau: Ke noi aku nei ka mea kūʻai aku i nā pono weld weld "Normalized": | |
| A: He kuhi hewa nō hoʻi kēia ma muli o ka loaʻa ʻana o nā flanges ma A105 a me A105 N, kahi e kū ai ʻo N no ka normalized. | |
| Eia naʻe, ʻaʻohe mea e like me A234WPBN. Hana ʻia nā mea hana maʻamau i kā lākou butt weld fittings i manaʻo ʻia ua hana ʻia ka hana mālama wela maʻamau, ʻoi loa no nā kuʻekuʻe a me nā Tees | |
| Pono ka mea kūʻai aku i "normalized" butt weld fittings e noi i nā pono WPL6 i kiʻekiʻe ka hua a ua maʻamau e like me ke kaʻina hana maʻamau. | |
| Nīnau: Poina ka mea kūʻai aku e haʻi i ka papa manawa paipu: | |
| A: Kūʻai ʻia nā lako Buttweld e like me ka nui o ka paipu akā pono e kuhikuhi ʻia ka papa kuhikuhi paipu e hoʻohālikelike i ka ID o ke kūpono i ka ID o ka paipu. Inā ʻaʻole i ʻōlelo ʻia ka papa inoa, e manaʻo mākou ua noi ʻia kahi pā maʻamau. | |
| Q; Poina ka mea kūʻai aku e haʻi aku i ka welded a i ʻole seamless butt weld kūpono: | |
| Loaʻa nā lako weld butt ma ka hoʻonohonoho welded a me ka ʻole. Hana ʻia ke kila kalapona a i ʻole ke kila kila kila me ka paipu ʻole a ʻoi aku ka nui o ke kumukūʻai. | |
| ʻAʻole maʻamau nā mea hoʻopili paipu seamless i nā nui nui ma mua o 12". Hana ʻia nā paipu paipu welded me ka ERW welded carbon steel a i ʻole ka paipu kila kila. Loaʻa iā lākou ma ka nui ½" a hiki i ka 72" a ʻoi aku ke kumukūʻai ma mua o nā mea pono ʻole. | |
| Nīnau: He aha ke ʻano o ka Short Radius (SR) a i ʻole Long Radius (LR)? | |
| A: E lohe pinepine ʻoe i ka kuʻe lima SR45 a i ʻole LR45 elbow. ʻO ka 45 a i ʻole 90 e pili ana i ke kihi o ka piko no ka hoʻopili ʻana i ka buttweld e hoʻololi i ke ala o ke kahe. | |
| ʻO kahi kuʻekuʻe radius lōʻihi (LR 90 Elbow a i ʻole LR 45 kuʻekuʻe) e loaʻa ka piko paipu he 1.5 manawa ka nui o ka paipu. No laila, he 6 iniha LR 90 he radius piko he 1.5 x ka nui paipu nominal. | |
| ʻO kahi kuʻekuʻe radius pōkole (SR45 a i ʻole SR90) he piko paipu e like me ka nui o ka mea kūpono, no laila he 6” SR 45 ka radius piko he 6” ka nui o ka paipu inoa. | |
| Q: He aha ka 3R a i ʻole 3D kuʻekuʻe paipu kūpono? | |
| A: ʻO ka mea mua, hoʻohana like nā huaʻōlelo 3R a i ʻole 3D. ʻO kahi kuʻekuʻe kuʻekuʻe 3R butt weld elbow he radius piko he 3 manawa ka nui o ka paipu inoa. Ua like ka kuʻekuʻe lima 3R me nā Kuʻekuʻe 3D | |
