O se flange lap-joint e manaʻomia ai ni vaega paipa se lua mo itu taʻitasi o le fesoʻotaʻiga flanged, o se pito stub ma se flange backing loose. O le flange backing loose e fetaui i luga o le lautele i fafo o le pito stub, lea e faʻapipiʻi i le butt-welding i le paipa. O le flange backing e le faʻapipiʻiina i le paipa, ma e mafai ona faʻataʻamilomilo, lea e aoga tele pe a manaʻomia le faʻatulagaina o flanges i le taimi e faʻatūina ai.

E le gata i lea, ona e le pa'i le flange lagolago i le vai o le faagasologa, e mafai ona faia i se mea e le tete'e tele i le 'ele. Mo se fa'ata'ita'iga, afai e 'ele le faagasologa ma e mana'omia le paipa e fai i le u'amea e le pala, e pei o le ASTM A312 TP316L, e tatau fo'i ona faia le pito o le stub i le SS 316L; peita'i, e mafai ona faia le flange lagolago i le ASTM A105 e taugofie.

O lenei metotia o le so'oga e lē malosi e pei o le uelo ua fa'apipi'i ae e sili atu nai lo le fa'apipi'iina o le uelo fa'amau, uelo soketi, ma le fa'apipi'i i luga; peita'i, e sili atu le taugata e fa'atino ai, aua e mana'omia ai se uelo fa'apipi'i atoa ma e mana'omia ai vaega e lua.

O le a faʻaaogaina i taimi uma le Stub End faʻatasi ma le Lap Joint flange, e fai ma backing flange.

O nei feso'ota'iga flange e fa'aogaina, i fa'aoga maualalo le mamafa ma fa'aoga e le taua tele, ma o se metotia taugofie o le flanging.
Mo se faʻataʻitaʻiga, i se faiga paipa uʻamea e le gaoia, e mafai ona faʻaogaina se flange uʻamea kaponi, aua e le paʻi atu i le oloa i totonu o le paipa.

E maua pito o paipa i toetoe lava o lautele uma. O fua ma le fa'apalepale o fua o lo'o fa'amatalaina i le tulaga fa'atonuina ASME B.16.9. O pito o paipa mama e tete'e atu i le 'ele o lo'o fa'amatalaina i le MSS SP43.

• O le sa'olotoga e feliuliua'i ai i le paipa e faafaigofie ai ona fa'atulaga pu o fa'amau o le flange e feteenai.
• O le leai o se fesootaʻiga ma le vai i totonu o le paipa e masani ona faʻatagaina ai le faʻaaogaina o flanges uʻamea kaponi taugofie ma paipa e teteʻe atu i le 'ele.
• I faiga e vave ona pala pe pala, e mafai ona toe fa'aleleia ia flanges mo le toe fa'aaogaina.

1. Foliga
foliga mafolafola, o le Radius e sili ona taua

2. Fa'atasi ai ma le ogatotonu po'o le leai fo'i o le ogatotonu

3. Fa'auma o foliga
O le fa'auma i luga o le flange e fuaina o le Arithmetical Average Roughness Height (AARH). O le fa'auma e fuafuaina e le tulaga fa'atonuina o lo'o fa'aaogaina. Mo se fa'ata'ita'iga, o le ANSI B16.5 e fa'amaoti mai ai fa'auma o foliga i totonu o le va o le 125AARH-500AARH (3.2Ra i le 12.5Ra). O isi fa'auma e maua pe a mana'omia, mo se fa'ata'ita'iga 1.6 Ra max, 1.6/3.2 Ra, 3.2/6.3Ra po'o le 6.3/12.5Ra. O le va o le 3.2/6.3Ra e sili ona taatele.

Fa'ailogaina ma le afifiina

• O vaega taʻitasi e faʻaaoga ai le ata palasitika e puipui ai le fogāeleele

• Mo u'amea e le gaoia uma e fa'aputuina i le pusa plywood. Mo u'amea tetele e fa'aputuina le carbon flange i le pallet plywood. Pe mafai fo'i ona fa'apitoa le fa'aputuina.

• E mafai ona faia le fa'ailoga o felauaiga pe a talosagaina

• E mafai ona vaneina pe lolomi fa'ailoga i luga o oloa. E talia le OEM.

Faiga o le gaosiga

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.
