AWWA C207 Class B (86 Psi) Blind-Flanges

AWWA C207 Class B dig muag flanges yog ib feem ntawm American Water Works Association (AWWA) tus qauv rau steel yeeb nkab flanges. Chav B qhia qhov ntsuas siab ntawm flange, uas nyob rau hauv rooj plaub no yog 86 psi (phaus ib square inch). Qhov muag tsis pom flanges yog siv los kaw qhov kawg ntawm cov yeeb nkab lossis lub nkoj qhib, muab kev yooj yim rau kev tshuaj xyuas, tu, lossis hloov kho. Cov flanges no feem ntau yog siv rau hauv cov khoom siv dej, cov chaw kho dej khib nyiab, thiab lwm yam kev siv uas AWWA cov qauv ua raws.

AWWA C207 Class B (86 psi) Qhov muag tsis pom Flanges feem ntau yog tsim los ntawm ntau yam ntaub ntawv thiab qib kom haum raws li qhov kev thov sib txawv:

Khoom siv:

Iron Ductile (Qib 65-45-12)

Carbon hlau (ASTM A105)

Stainless hlau (ASTM A182 F304 F316)

Alloy hlau (ASTM A182 F11, F22)

Khoom Qib:

Iron Ductile (Qib 65-45-12): Cov khoom no muaj lub zog siab thiab corrosion kuj, ua rau nws tsim nyog rau cov kav dej, cov chaw kho dej khib nyiab, thiab lwm yam kev siv.

Carbon Steel (ASTM A105): Paub txog nws qhov zoo tshaj plaws weldability thiab toughness, carbon steel flanges feem ntau yog siv nyob rau hauv high-pressure thiab high-temperature daim ntaub ntawv nyob rau hauv kev lag luam xws li roj thiab roj, petrochemical, thiab lub zog tsim.

Stainless hlau (ASTM A182 F304, F316): Stainless hlau flanges muab kev tiv thaiv corrosion zoo heev thiab tsim nyog rau cov ntawv thov uas muaj kev txhawj xeeb, xws li kev ua tshuaj lom neeg, zaub mov thiab dej haus, thiab kev lag luam tshuaj.

Alloy Steel (ASTM A182 F11, F22): Alloy steel flanges muab kev txhim kho lub zog, hardness, thiab tsis kam hnav thiab corrosion, ua rau lawv tsim nyog rau kev thov hauv cov chaw tsim hluav taws xob, refineries, thiab cov chaw ua tshuaj.

Daim Ntawv Thov: AWWA C207 Class B Dig Muag Flanges nrhiav daim ntawv thov hauv ntau yam kev lag luam thiab cov txheej txheem suav nrog:

Cov khoom siv dej

Cov chaw kho dej khib nyiab

Kev ua tshuaj lom neeg

Roj thiab roj ntau lawm

Petrochemical kev lag luam

Cov nroj tsuag tsim hluav taws xob

Kev ua zaub mov thiab dej haus

Pharmaceutical kev lag luam

Cov flanges no yog siv los kaw qhov kawg ntawm cov kav dej lossis cov hlab ntsha, muab kev nkag tau yooj yim rau kev tshuaj xyuas, kev saib xyuas, lossis kev hloov kho thaum ua kom muaj kev sib tsoo-pov thawj.
