Hluav taws tiv thaiv steel yeeb nkab

 

 

Cov Hluav Taws Xob Cov Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob tua hluav taws tsuas yog ua raws cov qauv hauv qab no:

Suav Lub Tebchaws (GB):

 

GB 50974-2014 "Cov Cai Technical for Hluav Taws Xob Hluav Taws Xob thiab Hluav Taws Kub Hydrant System": Qhov no yog txoj cai tseem ceeb rau kev xaiv hluav taws xob hauv tsev, kev tsim nyog, kev lees paub, thiab tso cai rau kev siv lwm cov khoom lag luam hauv tebchaws uas tau raws li nws cov kev cai.

 

 

Cov Qauv Yeeb Yam:

• Galvanized steel kav dej (GB / T 3091 {-}} kub kua galvanized steel kav yog xaiv). Tus qauv siv dav tshaj plaws.

 

• Galvanized steel yeeb (Seamless steel yeeb nkab): GB / T 8163 {{1} {1} {1} Seamless Steel Kave "(feem ntau kho nrog kub-dip Galvanizing).

 

• Ciaj Ua Yeeb Nkab Hlau Yeeb: GB / T 13295-2019 "Zas Hlau Kav Hlau, Fittings thiab Accessories rau Dej Thiab Roj Pipelines". Nws feem ntau siv nyob rau hauv cov kav nkoj faus.

 

• Stainless Hlau Kav: GB / T 19228.2 {}}}}}} partless stainless hlau

 

• Tooj liab leeg: GB / T 18033-2017 "Seamless tooj liab kav dej thiab tooj liab roj pipes".

 

• Chlorinated Polyvinyl Tshuaj Chloride (PVC- C): GB / T 18993.2 {}}}.

Cov Qauv Thoob Ntiaj Teb / Txawv Tebchaws:

 

ISO:Cov qauv tseem ceeb ntawm cov koom haum thoob ntiaj teb rau cov qauv.

 

ASTM (USA):xws li astm A53 (ASTM A106 (ASEM A1095 (xws li cov phiaj xwm steel hlau), welded dub kav lossis cov phiaj xwm dub}}}}}} cov dej num sib txawv), nws yuav tsim nyog xa mus rau.

 

Din (Lub teb chaws Yelemees):Tus qauv kev lag luam German uas qee zaum qee zaum tau hu ua.

 

En (European Union):Piv txwv li, en 10312 siv rau cov kav dej hlau stainless hlau.

 

BS (UK):Xws li BS 1387 cov yeeb nkab steel.

 

 

Raws li cov qauv saum toj no thiab kev nyab xeeb cov cai, kev tiv thaiv hluav taws yuav tsum muaj cov yam ntxwv hauv qab no:

1.High high - bearing capacitY: (Qhov no yog qhov tseem ceeb tshaj plaws thiab qhov tseem ceeb.)

 

• Nws yuav tsum muaj peev xwm los nrog cov kev ntsuas siab tshaj plaws ntawm cov txheej txheem thaum lub sijhawm ua haujlwm tau pib (feem ntau yog 1.5 zaug ua haujlwm siab thiab muaj ntau dua lossis sib npaug ntawm 1.4MPA).

 

• Kev xaiv cov yeeb nkab cov khoom siv thiab cov phab ntsa tuab yuav tsum tau nruj me ntsis kom ntseeg tau tias nws tsis tawg lossis deform loj hauv qab kev ua haujlwm tsis zoo.

2.Txhua corrosion tsis kam

 

Sab hauv corrosion:

Corrosion uas tej zaum yuav tshwm sim los ntawm ntev - lub sij hawm zoo li qub cia los yog hluav taws kub-}} kev ntaus dej siv. Nws yog ib qho tsim nyog yuav kom ntseeg tau tias sab hauv phab ntsa ntawm cov yeeb nkab tsis ua nplai lossis xeb, kom tsis txhob muaj kev txo qis thiab txo qis hauv cov kabmob muaj peev xwm.

 

Kev mob corrosion sab nraud:

• Kev nthuav tawm lossis sab hauv tsev: nws xav tau yoog rau huab cua huab cua, muaj peev xwm ua tau ib puag ncig tshuaj, thiab lwm yam.

 

• Kev faus rau hauv av: nws yuav tsum muaj peev xwm tiv taus av corrosion thiab pluaj tam sim no corrosion. Feem ntau, nws yog qhov yuav tsum tau tias lub phab ntsa sab nraud muaj cov tshuaj tiv thaiv kab mob hauv av, thiab cov tshuaj tiv thaiv corrosion (}

 

• Tsawb / Ntsev Tsuag Ib puag ncig, xws li cov chaw hiav txwv hiav txwv thiab cov ntug dej hiav txwv, muaj cov kav dej hiav txwv,} corrosion galvanized kav.

 

Kev ua haujlwm ib puag ncig yog: rau sab hauv tsev tawm lossis siv cov kav hlau loj (nrog rau sab hauv lossis sab hauv av Stainless hlau thiab tooj liab kav lawv tus kheej tau zoo heev corrosion tsis kam, tab sis lawv yog kim.

Txhim khu kev qha seading kev ua tau zoo thiab interface lub zog:

 

Txoj kev sib txuas ntawm cov kav dej (xov paj, flanged, welded, crimed, thiab lwm yam) yuav tsum muaj kev cuam tshuam los ntawm kev kub siab thiab dej sib ceg. Lub interface muaj zog yuav tsum tau ze rau lossis sib npaug rau lub zog ntawm cov yeeb nkab nws tus kheej.

 

Grooved txuas (clamp hom) yog siv dav vim nws qhov yooj yim, muaj peev xwm tso cai rau cov khoom lag luam muaj pov thawj). Flange kev sib txuas kuj tseem siv nyob rau hauv loj {2} txoj hauj lwm uas hla, twj tso kua mis chav, thiab dej tank tawm, thiab lwm yam.

Me me ntws tawm tsam (flight sab hauv):

 

• Sab hauv phab ntsa yuav tsum yog du thiab tiaj li ua tau (sab hauv phab ntsa ntawm galvanized steel kav yog cov roj av dub thiab cov kav dej tooj liab tau du los ntawm lawv tus kheej), kom txo qis taub hau (Raws -- Txoj kev tiv thaiv), thiab cov kev sib ntaus sib tua dej ntim thiab dej siab thiab kev sib ntaus sib tua.

 

• Zam kev ua kom muaj kev nce ntxiv tom qab xeb thiab tawg ntawm sab hauv phab ntsa.

Lub zog zoo thiab lub zog:

 

• Saib xyuas cov duab ruaj khov raws li lub siab thiab tiv thaiv kev tawm tsam ntau dhau.

 

• Nws tuaj yeem tuav txoj kev ncaj ncees hauv qab kev txiav txim ntawm sab nraud rog xws li kev teeb tsa, av qeeg thiab av hais txog av. Grooved sib txuas muaj qee qhov zoo hauv cov nam no (cia rau me me-} lub kaum defgle deflection).

Hluav Taws Kub Kuj Zoo:

 

Txawm hais tias ntws sab hauv cov yeeb nkab yog sib xyaw ntawm cov dej lossis ua npuas dej, uas yog cov khoom siv txhawb nqa lossis cov khoom siv ntawm cov yeeb nkab nws tus kheej yuav tsum muaj hluav taws tsis txaus. Cov kav dej hlau ib txwm ua tiav qhov xav tau no.

 

Txwv tsis pub cov kav dej yas ntxiv: cov txheej txheem kev txwv tsis pub siv cov dej hauv qab no, thiab lawv tsis tau muaj kev tiv thaiv hluav taws los ntawm cov raj xa dej los ntawm cov raj xa hluav taws Yeeb nkab ntawm cov dej twj tso rau sab xub ntiag ntawm cov ntub luv lub valve, uas tej zaum yuav nyob rau hauv lub siab {3} {{}} lub xeev pub dawb txhua lub sijhawm.

Lub neej ntev kev pab lub neej:

Kev tiv thaiv hluav taws kub feem ntau yog tsim tau kom muaj lub neej kev pabcuam ntev (ntau caum xyoo). Raws li ib qho tseem ceeb tivthaiv, cov ntaub ntawv thiab anti {{1} Corrosion ntsuas ntawm cov kav dej yuav tsum ua kom ntev} kev ntseeg tau thiab hloov ntau zaus.

Ib qho yooj yim rau txheej txheem thiab nruab:

Cov ntaub ntawv yuav tsum tau yooj yim rau kev txiav, xws li me me - txoj kev intere txoj cai ntawm lub tsev tsim qauv. Qhov no tseem yog ib qho ntawm cov laj thawj rau lub luag haujlwm ntawm kev sib txuas nrog.

Muaj kev nyab xeeb thiab tsis - kev toxic (rau cov khoom siv dej):

Cov ntaub qhwv cov yeeb nkab thiab cov tsho tiv no ua rau thauj cov khoom siv hauv tsev rau ob qho tib si kev tiv thaiv kev nyab xeeb, thiab sib ntsib cov roj hmab haus (qee cov kav dej yas muaj cov cai no).

 

 

Cov tub ntxhais muaj kev tiv thaiv hluav taws xob nyob hauv: Thaum lub sij hawm tseem ceeb heev (thaum muaj hluav taws kub tawm), nws yog qhov tsim hluav taws kub tawm), nws yog qhov kev sib ntaus sib tua nruab nrab (dej sib tov) rau hluav taws. Qhov no txiav txim siab tias nws yuav tsum nruj me ntsis raws li cov qauv hauv tebchaws (ob qho tib si sab hauv, kev kub ntxhov, muaj kev kub ntxhov (lossis siv sijhawm ntev.

 

Kev xaiv cov ntaub pua yeeb (xws li galvanized steel kav, thiab lwm yam) muaj kev pab cuam tshuam nrog cov kev cai tshwj xeeb thiab cov kev xav tau ntawm cov kev qhia tshwj xeeb. Galvanized steel kav dej (tshwj xeeb tshaj yog kub- pa tawm ntawm cov yeeb nkab hauv cov hluav taws tiv thaiv kev tiv thaiv vim lawv qhov kev ua tau zoo thiab kev lag luam.
