kila kila i hoʻopaʻa ʻia i ka hui ʻana o ka flange wehe ʻia kola sch stub end flange

Pono kahi flange lap-joint i ʻelua mau ʻāpana paipu no kēlā me kēia ʻaoʻao o ka pilina flanged, kahi hopena stub a me kahi flange backing wehe. Hoʻokomo ka flange backing wehe ma luna o ke anawaena o waho o ka hopena stub, kahi i hoʻopaʻa ʻia me ka butt i ka paipu. ʻAʻole i hoʻopaʻa ʻia ka flange backing i ka paipu, a hiki ke hoʻohuli ʻia, he mea pono loa ia i ka wā e pono ai ke kuhikuhi i nā flanges i ka wā o ke kūkulu ʻana.

Eia kekahi, ʻoiai ʻaʻole pili ka flange hope me ke kahe hana, hiki ke hana ʻia me kahi mea i emi iki ka pale ʻana i ka ʻino. No ka laʻana, inā ʻino ke kaʻina hana a koi ʻia ka paipu e hana ʻia me ke kila kila, e like me ASTM A312 TP316L, a laila pono e hana ʻia ka hopena stub me SS 316L; akā naʻe, hiki ke hana ʻia ka flange hope me ka ASTM A105 ʻoi aku ka makepono.

ʻAʻole ikaika kēia ʻano hana o ka hui ʻana e like me ka flange ʻāʻī i hoʻopili ʻia akā ʻoi aku ka maikaʻi ma mua o nā pilina wili ʻia, socket weld, a me nā pilina paheʻe; akā naʻe, ʻoi aku ke kumukūʻai o ka hoʻokō ʻana, no ka mea, pono ia i kahi weld butt penetration piha a koi ʻia ʻelua mau ʻāpana.

E hoʻohana mau ʻia kahi Stub End me kahi Lap Joint flange, ma ke ʻano he backing flange.

Hoʻopili ʻia kēia mau pilina flange, ma nā noi haʻahaʻa a me nā noi koʻikoʻi ʻole, a he ala maʻalahi ia no ka flanging.
I loko o kahi ʻōnaehana paipu kila kila, no ka laʻana, hiki ke hoʻopili ʻia kahi flange kila kalapona, no ka mea, ʻaʻole lākou e hoʻopili ʻia me ka huahana i loko o ka paipu.

Loaʻa nā Stub Ends ma aneane nā anawaena paipu āpau. Ua wehewehe ʻia nā ana a me nā hoʻomanawanui dimensional ma ke kūlana ASME B.16.9. Ua wehewehe ʻia nā Stub Ends (fittings) kūpaʻa i ka pala māmā ma MSS SP43.

• ʻO ke kūʻokoʻa e milo a puni ka paipu e hiki ai ke hoʻopili i nā lua bolt flange kū'ē.
• ʻO ka nele o ka hoʻopili ʻana me ka wai i loko o ka paipu e ʻae pinepine i ka hoʻohana ʻana i nā flanges kila kalapona haʻahaʻa me ka paipu kūpaʻa i ka pala.
• I nā ʻōnaehana e pala koke ana a ʻōpala paha, hiki ke hoʻopakele ʻia nā flanges no ka hoʻohana hou ʻana.

Pipe fittings are crucial components in the piping system, used for connection, redirection, diversion, size change, sealing or controlling the flow of fluids. They are widely applied in fields such as construction, industry, energy and municipal services.

Key Functions: It can perform functions such as connecting pipes, changing flow direction, dividing and merging flows, adjusting pipe diameters, sealing pipes, controlling and regulating.

Application Scope:

• Building water supply and drainage: PVC elbows and PPR tris are used for water pipe networks.
• Industrial pipelines: Stainless steel flanges and alloy steel elbows are used to transport chemical media.
• Energy transportation: High-pressure steel pipe fittings are used in oil and gas pipelines.
• HVAC (Heating, Ventilation, and Air Conditioning): Copper pipe fittings are used to connect refrigerant pipelines, and flexible joints are used for vibration reduction.
• Agricultural irrigation: Quick connectors facilitate the assembly and disassembly of sprinkler irrigation systems.
