Nīnau a me nā pane ( Q&A )
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 nā nui ½" a hiki i 72" a ʻoi aku ke kumukūʻai ma mua onā 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
