I-SS Butt Welded Fittings iyavutha

Inkcazo ye-But Welded Fittings

Iimpawu / Iimpawu

• Izifakelo ze-Buttweld zizifakelo zemibhobho ezisetyenziselwa ukutshintsha indlela yombhobho (ingqiniba), ukunciphisa/ukwandisa ubungakanani bobhobho bobhobho (izinciphisi), isebe (iinzwane, ukunqumla) okanye ukumfamekisa umbhobho (i-butt weld cap)
• Ufakelo lwe-buttweld lufumaneka ngokwemilo ezininzi (ingqiniba, iiteyi, izinciphisi, iminqamlezo, iikepusi, ii-stub ends), imigangatho yemathiriyeli (ikhabhoni, i-high-yield carbon, low-alloy, stainless, duplex, ne-nickel alloys),
kunye nemilinganiselo (i-intshi ezi-2 ukuya kuma-24 ekwenziweni ngokungenamthungo, kwaye zidityaniselwe ubungakanani bemibhobho emikhulu).
• Iimpawu eziphambili zofakelo lwe-buttweld yi-ASME B16.9 (i-carbon ne-alloy fittings) kunye ne-MSS SP 43 (edibanisa i-ASME B16.9 yensimbi engenasici, i-duplex, kunye ne-nickel alloy fittings BW).
• Kanye njengokuba umbhobho uthengiswa ukusuka kwiShedyuli ye-10 ukuya kwiShedyuli ye-160, izifakelo zemibhobho ye-butt weld zithengiswa ngendlela efanayo.
Ufakelo lwe weld butt weld luxhaphake kakhulu kwintsimbi engenastainless ngenxa yoncedo lweendleko. I-Sch 10S, i-SCH40SUfakelo lwe-SSzikwaxhaphake kakhulu kwintsimbi engenastainless butt weld fittings.
Izinto eziqhelekileyo zokufakelwa kwe-butt weld yi-A234 WPB (i-A & C iyafumaneka), i-High Yield Carbon Steel, i-Stainless Steel 304 kunye ne-316 kunye ne-Nickel Alloys.
• Izifakelo zemibhobho edityanisiweyo kwikhabhoni yentsimbi kunye nentsimbi engatyiwa zizinto ezidibanisayo ezenza kube lula ukudityaniswa kweevalvu;
imibhobho kunye nezixhobo kwisixokelelwano semibhobho. Ufakelo oludityanisiweyo luncoma iiflange zemibhobho kuyo nayiphi na inkqubo yemibhobho kwaye ivumela:
1.Ukutshintsha indlela yokuhamba kwindlela yokubhobhoza
2.Ukudibanisa okanye imibhobho edibeneyo kunye nezixhobo
3. Ukubonelela ngamasebe, ukufikelela kunye nokuhamba kwezixhobo ezincedisayo

Ukufakwa kwemibhobho kuvula Inkqubo yeMveliso

1. Ukwamkela nokuHlolwa

2. Ukuchongwa kwezinto

3. I-Elbow/ Reducer/Tee/Cap Shape Forming

4. Inkqubo yeWelding

4. Unyango lobushushu

5. Ukudutyulwa kokudubula

6. Emva kweBeveled

7. Emva kokupholisha

Imibuzo neempendulo ( Q&A )

Q:Umthengi ucele ukufakwa kwe-butt weld kwi-A105:
A: Uninzi lwezinto eziqhelekileyo ze-carbon steel buttweld fitting material yi-A234WPB. Ilingana ne-A105 flanges, nangona kunjalo akukho nto ifana ne-A105 okanye i-A106 butt weld fitting.
I-A106 Gr.B yeyebakala lombhobho. Izixhobo ze-A234WPB zenziwe ngemibhobho ye-A106GR.B. I-A105 yinto esuka kwiBar eyenziwe ukuba ibe yiFittings yoxinzelelo oluphezulu okanye iFlange
Q: Ucela umthengi "Eziqhelekileyo" izifakelo ze-butt weld:
A: Oku kukwayingcamango ephosakeleyo ekubeni iiflange zifumaneka kwi-A105 kunye ne-A105 N, apho i-N imele i-normalized.
Nangona kunjalo, akukho nto injenge-A234WPBN. Abavelisi benza ukuba ii-butt ze-weld zibe zilungelelaniso zabo zathathwa njengenkqubo eqhelekileyo yokunyanga ubushushu yayenziwa, Ngokukodwa kwingqiniba kunye neeTees.
Umxumi odinga izifakelo ze-weld "eziqhelekileyo" ze-butt kufuneka zicele i-WPL6 fittings enesivuno esikhulu kwaye yenziwe yesiqhelo njengenkqubo eqhelekileyo.
Umbuzo: Umthengi uyalibala ukukhankanya ishedyuli yombhobho:
A: Izifakelo ze Buttweld zithengiswa ngokobungakanani bombhobho kodwa ishedyuli yombhobho mayicaciswe ukuze ingqinelane ne-ID yofakelo kwi-ID yombhobho. Ukuba akukho shedyuli ikhankanywe, siya kuthatha udonga oluqhelekileyo luceliwe.

Q; UmThengi uyalibala ukukhankanya i-welded okanye i-butt engenamthungo ehambelanayo:
Ufakelo lwe-butt weld luyafumaneka kuzo zombini i-welded kunye noqwalaselo olungenamthungo. I-butt ye-weld carbon steel engenamthungo okanye ukufakela intsimbi eyenziwe ngombhobho ongenamthungo kwaye kubiza kakhulu.
Ufakelo lwemibhobho engenamthungo AYIQHELEKILEYO ngokobukhulu obungaphezu kwe-12”. Ufakelo lwemibhobho edityanisiweyo yenziwe nge-ERW edityanisiweyo yentsimbi yekhabhoni okanye umbhobho wentsimbi engenasici. Zifumaneka ngeesayizi ½” ukuya kuma-72” kwaye zifikeleleka kakhulu kuneizixhobo ezingenamthungo.
Umbuzo: Kuthetha ukuthini i-Short Radius (SR) okanye iLong Radius (LR)?
A: Uya kuhlala uva ingqiniba ye-SR45 okanye i-LR45 ingqiniba. I-45 okanye i-90 ibhekiselele kwi-engile yokugoba ukuze i-buttweld ilingane ukutshintsha icala lokuhamba.
I-elbow ye-radius ende (i-LR 90 Elbow okanye i-LR 45 elbow) iya kuba ne-bend yepayipi eya kuba ngamaxesha angama-1.5 ubukhulu bombhobho. Ngoko ke, i-6 intshi ye-LR 90 ineradiyasi egobayo eyi-1.5 x yobungakanani bombhobho oqhelekileyo.
Ingqiniba yeradiyasi emfutshane (SR45 okanye SR90) inombhobho wokugoba olingana nobukhulu bokufaniswa, ngoko ke i-6” SR 45 ineradiyasi egobayo eyi-6” yobungakanani bombhobho oqhelekileyo.

Q: Yintoni i-3R okanye i-3D efakwe kwingqiniba yombhobho?
A: Okokuqala, amagama athi 3R okanye 3D asetyenziswa ngokufanayo. Ingqiniba ye-3R ye-butt ye-weld ine-radius egobayo ephindwe ka-3 ubungakanani bombhobho oqhelekileyo. Ingqiniba ka-3R ilingana ne-3D Elbows
