AWWA C207 ASTM A105 Chitsulo Cha Mpweya Chachikulu Chachikulu Chokhazikika Chokhazikika Pa Flange

Zogulitsa Zambiri

Chiyambi cha Zamalonda

AWWA C207 ndi muyezo wopangidwa ndi American Water Association kuti ulamulire kamangidwe, kupanga, kuyesa, ndi kugwiritsa ntchito ma flanges owotcherera pakhosi. Ma flanges opangidwa ndi khosi nthawi zambiri amagwiritsidwa ntchito pamapaipi olumikizira mapaipi amitundu yosiyanasiyana kapena zida, komanso kulumikiza ma valve, mapampu, ndi zida zina.

Muyezo wa AWWA C207 umatanthawuza mitundu yosiyanasiyana ya ma flanges opangidwa ndi khosi, kuphatikiza makulidwe osiyanasiyana, kukakamiza, ndi ma diameter mwadzina, kuti akwaniritse zosowa zamapaipi osiyanasiyana. Zotsatirazi ndizodziwika bwino mu muyezo uwu:

Makulidwe:

Muyezo wa AWWA C207 umaphatikizapo miyeso ya metric ndi yachifumu, yokhala ndi miyeso ya metric kuphatikiza DN (DN15 mpaka DN6000) ndi miyeso yachifumu kuphatikiza NPS (1/2 "mpaka 144").

Chiyembekezo:

Muyezo wa AWWA C207 umatchula kukakamiza kosiyanasiyana, kuphatikiza Class D (175 psi), Class E (275 psi), Class F (300 psi), Class G (300 psi), Class H (300 psi), Class J (300 psi). ), etc.

Diameter mwadzina:

Muyezo wa AWWA C207 umatchulanso ma diameter osiyanasiyana, kuphatikiza DN 15 mpaka DN 6000, NPS 1/2 "mpaka 144", etc.

Neck slip pa kuwotcherera flange ndi cholumikizira mapaipi omwe amagwiritsidwa ntchito nthawi zambiri, oyenera kulumikiza mapaipi, mavavu, mapampu, ndi zida zina zamitundu yosiyanasiyana kapena kukula kwake.

Chojambula chokhazikika pa flangenthawi zambiri zimakhala ndi mbale ziwiri zafulange, khosi lolumikiza mbale ziwiri za flange, mabawuti, ndi ma gaskets. Mosiyana ndi khosi welded flange, khosi welded flange kugwirizana amafuna kugwiritsa ntchito mabawuti ndi gaskets kukonza, osati kudzera matako kuwotcherera.

Muyezo wa AWWA C207 umatchula mitundu yosiyanasiyana yowotcherera khosi lathyathyathya, kuphatikiza miyeso ya metric ndi mfumu, milingo yosiyana, ndi magiredi azinthu. Mwachitsanzo, mulingo umatchula milingo sikisi ya kupanikizika: Kalasi D, Kalasi E, Kalasi F, Kalasi G, Kalasi H, ndi Kalasi J. Pakati pawo, Kalasi D ndi mlingo wotsikirapo kwambiri woyenerera kupanikizika kocheperako, pamene Gulu J ndi kuthamanga kwapamwamba kwambiri koyenera kukakamiza kwambiri ntchito.

Kuphatikiza apo, mulingo wa AWWA C207 umanenanso za kupanga, kuwongolera bwino, komanso zoyeserera zakhosi welded flangeskuonetsetsa kuti opangidwa khosi welded flanges kukwaniritsa zofunika muyezo. Pamene ntchito khosi welded flanges, m`pofunika kuonetsetsa kuti zakuthupi ndi mavuto mlingo wambale ya flange ndi khosindi ofanana, ndi kukhazikitsa ndi kuyesa malinga ndi zofunika muyezo kuonetsetsa chitetezo ndi kudalirika kwa dongosolo. Ma flanges okhotakhota okhotakhota amagwiritsidwa ntchito kwambiri pamapaipi apansi, kutentha pang'ono, kapena kutsika kwapaipi, monga madzi, mpweya wabwino, zowongolera mpweya, ndi zina.
