Socket Weld Flanges a pehea lākou e wili ʻia ai?

Ka wehewehe huahana kumu:

ʻO ka flange wiliwili kumuhe lehelehe me kekahi welau i wiliia i ka paipu kila a ua paa kekahi welau.

ʻO nā ʻano o ka ʻili o ke sila ʻana, ʻo ia ka helehelena kiʻekiʻe (RF), ka maka concave convex (MFM), ke alo a me ke alo groove (TG) a me ka maka hui (RJ)

Hoʻokaʻawale ʻia nā mea waiwai i:

1. ʻO ka hao hao: ASTM A105, 20 #,Q235, 16Mn, ASTM A350 LF1, LF2CL1/CL2, LF3 CL1/CL2, ASTM A694 F42, F46, F48, F50, F52, F56, F60, F65, F70;

2. Ke kila Stainess: ASTM A182 F304, 304L, F316, 316L, 1Cr18Ni9Ti, 0Cr18Ni9Ti, 321, 18-8;

Kaʻina hana:

kiʻekiʻe kiʻekiʻe CNC lathe huli ana, maʻamau lathe huli maikai, argon arc wiliwili a me na mea e ae.

Laulā noi:

boiler, ipu kaomi, petroleum, oihana kemika, kapili moku, pharmacy, metallurgy, machinery, stamping elbow food a me na oihana e ae.

Hoʻohana maʻamau i nā paipu me PN ≤ 10.0MPa a me DN ≤ 40.

Pehea e wili ʻia ai nā puʻu flanges?

ʻO ka maʻamau, komo ka paipu i loko o ka flange no ka wili ʻana ma ke kumu kuʻi. ʻO ka hoʻoheheʻe ʻana ʻo ia ka hoʻohana ʻana i ka flange welding butt e hoʻopaʻa ai i ka paipu a me ke alo o ka pū. ʻAʻole hiki ke hoʻopaʻa ʻia ka junction welded socket i ka nānā ʻana i ka radiographic, akā ʻoi aku ka maikaʻi o ka wili ʻana. No laila, ʻōlelo ʻia e hoʻohana i ka flange welding butt no ka hui kuʻi ʻana me nā koi kiʻekiʻe.

ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka welding butt ma mua o ka socket welding, a maikaʻi hoʻi ka maikaʻi ma hope o ka welding, akā paʻakikī ke ʻano o ka ʻike. ʻO ka hoʻoheheʻe ʻana i ke kīpē ma lalo o ka nānā ʻana i ka radiographic, a ʻo ka hoʻoheheʻe ʻana i ke kumu e hoʻopili ʻia i ka ʻāpana magnetic a i ʻole ka nānā ʻana penetrant (e like me ke kila kalapona no ka ʻāpana magnetic a me ke kila kuhili no ka nānā penetrant). Inā ʻaʻohe koi kiʻekiʻe o ka wai i loko o ka pipeline no ka welding, ʻōlelo ʻia ka socket welding no ka ʻike maʻalahi

Hoʻohana nui ʻia ke ʻano hoʻohui o ka socket welding no ka hoʻopili ʻana i nā kiwi liʻiliʻi anawaena a me nā paipu, nā paipu paipu a me nā paipu. ʻO nā paipu anawaena liʻiliʻi ʻoi aku ka lahilahi, maʻalahi ke hoʻoluliluli ʻia a ʻokiʻoki ʻia, a paʻakikī hoʻi i ka wili ʻana, no laila ʻoi aku ka maikaʻi o ka wili ʻana. Eia kekahi, ʻo ka socket o ka socket welding ka hopena o ka hoʻoikaika ʻana, no laila hoʻohana ʻia ma lalo o ke kaomi kiʻekiʻe. Eia nō naʻe, loaʻa nō hoʻi nā pōʻino ʻole o ka welding socket. ʻO kekahi, ʻaʻole maikaʻi ke koʻikoʻi ma hope o ke kuʻi ʻana, a ua maʻalahi ka loaʻa ʻole ʻana o ke komo ʻana o ka welding. Aia nā āpau i ka ʻōnaehana paipu. No laila, ʻaʻole kūpono ka wili socket no nā ʻōnaehana paipu i hoʻohana ʻia no ka gap corrosion sensitive media a me nā ʻōnaehana paipu me nā koi maʻemaʻe kiʻekiʻe. Eia kekahi, ʻo ka mānoanoa o ka pā o nā paipu kiʻekiʻe kiʻekiʻe, ʻo nā paipu anawaena liʻiliʻi, he nui loa, no laila e pale ʻia ke kumu kuʻi ʻana inā hiki ke hoʻohana ʻia ka wili kī.

ʻO ka pōkole, ʻo nā welds socket nā welds fillet a ʻo nā welds butt nā welds butt. E like me ka ikaika a me ke koʻikoʻi o ka weld, ʻoi aku ka maikaʻi o ka hui ʻana ma mua o ka hui kumu, no laila pono e hoʻohana ʻia ka hui pū i ke kūlana me ke kiʻekiʻe o ke kaomi kiʻekiʻe a ma ke kula me nā kūlana noi maikaʻi ʻole.

ʻO ka hoʻoheheʻe ʻia ʻana o ka flange paipu me ka hoʻoheheʻe ʻia ʻana o ka palahalaha, ka hoʻoheheʻe ʻana a me ka wiliwili paheʻe.
