Tanthauzo ndi Tsatanetsatane wa Butt Weld Fittings

Buttweld Fittings general

Kuyika kwa chitoliro kumatanthauzidwa ngati gawo lomwe limagwiritsidwa ntchito pamapaipi, posintha njira, nthambi kapena kusintha kwa m'mimba mwake, ndipo imalumikizidwa ndi dongosolo. Pali mitundu yosiyanasiyana ya zoyikapo ndipo ndizofanana kukula ndi ndandanda monga chitoliro.

Zosakaniza zimagawidwa m'magulu atatu:

  • Zopangira za Buttweld (BW) zomwe miyeso yake, kulolerana kwake ndi zina zambiri zimafotokozedwa mumiyezo ya ASME B16.9. Zovala zosagwirizana ndi zopepuka zopepuka zimapangidwira ku MSS SP43.
  • Socket Weld (SW) zopangira Class 3000, 6000, 9000 zimatanthauzidwa mumiyezo ya ASME B16.11.
  • Zopangidwa ndi ulusi (THD), zopindika za Class 2000, 3000, 6000 zimatanthauzidwa mumiyezo ya ASME B16.11.

Mapulogalamu a Buttweld Fittings

Dongosolo la mapaipi ogwiritsira ntchito zida za buttweld lili ndi zabwino zambiri zobadwa nazo kuposa mitundu ina.

  • Kuwotcherera koyenera ku chitoliro kumatanthauza kuti sichiduka mpaka kalekale
  • Kapangidwe kazitsulo kosalekeza komwe kamapangidwa pakati pa chitoliro ndi koyenera kumawonjezera mphamvu ku dongosolo
  • Kusalala kwamkati mkati ndi kusintha kwapang'onopang'ono kumachepetsa kupsinjika ndi chipwirikiti ndikuchepetsa kuwonongeka kwa dzimbiri ndi kukokoloka.
  • Dongosolo la welded limagwiritsa ntchito malo ochepa

Bevelled End

Mapeto a zida zonse za buttweld ndi zopindika, zokulirapo kuposa 4 mm pazitsulo zosapanga dzimbiri za austenitic, kapena 5 mm pazitsulo zosapanga dzimbiri za ferritic. Maonekedwe a bevel kutengera makulidwe enieni a khoma. Mapeto a bevelled awa amafunikira kuti athe kupanga "butt weld".

Mitundu yodziwika bwino ya bevel

ASME B16.25 chimakwirira kukonzekera buttwelding malekezero a mapaipi zigawo kuti anagwirizana mu dongosolo mapaipi ndi kuwotcherera. Zimaphatikizapo zofunikira pakuwotcherera ma bevel, mawonekedwe akunja ndi amkati a zigawo zolemetsa, komanso pokonzekera malekezero amkati (kuphatikiza miyeso ndi kulolerana kwapakati). Zofunikira zokonzekera m'mphepete mwa weld zikuphatikizidwanso mumiyezo ya ASME (mwachitsanzo, B16.9, B16.5, B16.34).

Zofunika ndi Magwiridwe

Zida zomwe zimagwiritsidwa ntchito kwambiri popanga zida zopangidwa ndi chitsulo cha kaboni, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, aluminiyamu, mkuwa, galasi, mphira, mitundu yosiyanasiyana ya mapulasitiki, ndi zina zambiri.

Kuphatikiza apo, zopangira, monga mapaipi, pazifukwa zenizeni nthawi zina mkati zimakhala ndi zigawo zazinthu zamtundu wosiyana kotheratu, zomwe ndi "zolumikizira".

Zomwe zimapangidwira zimayikidwa panthawi yosankha chitoliro, nthawi zambiri, kuyenerera kumakhala kofanana ndi chitoliro.
