SS Butt Welded Fittings amawombera

Kufotokozera kwa Butt Welded Fittings

Mawonekedwe / Makhalidwe

• Zoyika za Buttweld ndi zopangira mapaipi zomwe zimagwiritsidwa ntchito posintha njira ya payipi (zigongono), kuchepetsa/kuwonjezera kukula kwa chitoliro (zochepetsera), nthambi (mapaipi, kuwoloka) kapena khungu la payipi (chipewa chowotcherera matako)
• Zopangira ma Buttweld zimapezeka m'mawonekedwe angapo (zigongono, mateti, zochepetsera, mitanda, zisoti, ma stub ends), makala azinthu (carbon, high-yield carbon, low-alloy, stainless, duplex, ndi nickel alloys),
ndi makulidwe ( mainchesi 2 mpaka 24 mu kuphedwa mosasunthika, ndi kuwotcherera kwa kukula kwa mapaipi okulirapo).
• Mfundo zazikuluzikulu za zida za buttweld ndi ASME B16.9 (zoyika kaboni ndi aloyi) ndi MSS SP 43 (yomwe imaphatikiza ASME B16.9 pazitsulo zosapanga dzimbiri, duplex, ndi nickel alloy BW).
• Monga momwe chitoliro chimagulitsidwa kuchokera pa Ndandanda 10 kufika pa Ndandanda 160, zida zowotcherera za matako zimagulitsidwa chimodzimodzi.
Zopangira welded butt weld ndizofala kwambiri muzitsulo zosapanga dzimbiri chifukwa cha mtengo wake. Sch 10S, SCH40SZithunzi za SSnawonso amapezeka kwambiri pazitsulo zosapanga dzimbiri zachitsulo.
Zida zodziwika bwino pazitsulo za matako ndi A234 WPB (A & C ikupezekanso), Chitsulo cha Carbon Chokwera Chokwera, Chitsulo chosapanga dzimbiri 304 ndi 316 ndi Nickel Alloys.
• Zida zomangira mapaipi muzitsulo za carbon ndi zitsulo zosapanga dzimbiri ndizo zigawo zomwe zimapangitsa kuti ma valve apangidwe,
mapaipi ndi zida pamapaipi. Zopangira zowotcherera zimayamika ma chitoliro amtundu uliwonse wamapaipi ndipo zimalola:
1.Sinthani mayendedwe oyenda mumayendedwe a mapaipi
2.Connect kapena mapaipi ophatikizana ndi zida
3. Kupereka nthambi, mwayi ndi zonyamuka pazida zothandizira

Mapepala aukadaulo aukadaulo a ANSI B16.9 zolumikizira mapaipi (Elbow)

Mafunso ndi Mayankho ( Q&A )

Q: Makasitomala adafunsa zowotcherera matako mu A105:
A: Zinthu zodziwika bwino za carbon steel buttweld ndi A234WPB. Ndilofanana ndi ma flange a A105, komabe palibe chinthu ngati A105 kapena A106 butt weld woyenerera.
A106 Gr.B ndi ya kalasi ya chitoliro. Zosakaniza za A234WPB zimapangidwa kuchokera ku mapaipi a A106GR.B. A105 ndi chinthu chochokera ku Bar chopangidwa kukhala High pressure Fittings kapena Flange
Q: Makasitomala amapempha "Normalized" butt weld zovekera:
A: Awanso ndi malingaliro olakwika popeza ma flange amapezeka mu A105 ndi A105 N, pomwe N imayimira normalized.
Komabe, palibe chinthu ngati A234WPBN. Opanga amawongolera zopangira zawo zowotcherera matako amaganiziridwa kuti njira yoyezera kutentha idachitika, Makamaka pamigongo ndi Tees.
Makasitomala omwe akufunika zowotcherera "zokhazikika" za butt akuyenera kupempha zolumikizira za WPL6 zomwe zimakhala zokolola zambiri ndipo zimasinthidwa ngati njira yokhazikika.
Q: Makasitomala amaiwala kutchula ndondomeko ya chitoliro:
A: Zopangira za Buttweld zimagulitsidwa malinga ndi kukula kwa chitoliro koma ndondomeko ya chitoliro iyenera kutchulidwa kuti ifanane ndi ID yofananira ndi ID ya chitoliro. Ngati palibe ndondomeko yomwe yatchulidwa, tidzaganiza kuti khoma lokhazikika likufunsidwa.

Q; Makasitomala amaiwala kutchula zowotcherera kapena zowotcherera m'matako:
Zopangira ma welds a Butt zimapezeka mumapangidwe onse owotcherera komanso opanda msoko. Chitsulo chosasokoneka cha chitsulo chosapanga dzimbiri kapena chitsulo chosapanga dzimbiri chimapangidwa ndi chitoliro chopanda msoko ndipo nthawi zambiri chimakhala chokwera mtengo.
Zoyikira mapaipi opanda msoko SI zachilendo kukula kuposa 12 ". Zitoliro zowotcherera zimapangidwa ndi ERW welded carbon steel kapena chitoliro chosapanga dzimbiri. Amapezeka mu makulidwe ½ "mpaka 72" ndipo ndi otsika mtengo kuposazosakaniza zopanda msoko.
Q: Kodi Short Radius (SR) kapena Long Radius (LR) amatanthauza chiyani?
A: Nthawi zambiri mumamva SR45 chigongono kapena LR45 chigongono. The 45 kapena 90 amatanthauza ngodya ya bend ya buttweld yoyenera kusintha komwe kumayendera.
Chigongono chachitali (LR 90 Elbow kapena LR 45 elbow) chidzakhala ndi kupindika kwa chitoliro komwe kudzakhala nthawi 1.5 kukula kwa chitoliro. Chifukwa chake, 6 inchi LR 90 ili ndi utali wopindika womwe ndi 1.5 x kukula kwa chitoliro mwadzina.
Chigongono chachifupi chozungulira (SR45 kapena SR90) chimakhala ndi chopindika cha chitoliro chomwe ndi chofanana ndi kukula kwake, kotero 6" SR 45 ili ndi utali wopindika womwe ndi 6" kukula kwake mwadzina.

Q: Kodi chitoliro cha 3R kapena 3D ndi chiyani?
A: Choyamba, mawu akuti 3R kapena 3D amagwiritsidwa ntchito mofanana. Chigongono cha 3R butt weld chili ndi utali wopindika womwe ndi wofanana ndi kukula kwa chitoliro. Chigongono cha 3R ndi chofanana ndi 3D Elbows
