1. Q: Dab tsi yog cov khoom siv tseem ceeb siv rau hluav taws tiv thaiv steel yeeb nkab?
A: Hluav taws tiv thaiv steel yeeb yeeb nkab yog ua los ntawm galvanized carbon hlau (xws li Q235b), coated nrog zinc rau kev txhim kho corrosion. Siab {- cov tshuab siab yuav siv seamless steel yeeb nkab (xws li 20 # steel).
Piv txwv li, sab hauv hluav taws kub tshuab hluav taws xob tshuab feem ntau siv DN65 {} Cov yeeb nkab welded welded, thaum lub siab tshuaj txau welded, siv Sch40 seamless steel yeeb nkab.
2. Q: Cov kev sib txuas yog dab tsi rau hluav taws tiv thaiv steel yeeb nkab?
A: Cov hau kev sib xws suav nrog:
Xov txuas kev sib txuas (galvanized yeeb nkab DN tsawg dua los yog sib npaug rau 80mm, xws li hluav taws herydant ceg kav);
Flange kev sib txuas (loj - txoj hauj lwm uas hla dhau kev ua kom nquag plias, xws li tso kua mis inlets thiab outlets);
Groove kev txuas (clamp) (yeeb nkab DN ntau dua lossis sib npaug nrog 100mm, kev teeb tsa ceev, xws li Khw Khw Muag Khoom Hluav Taws Xob).
Piv txwv li, lub siab -} Ris lub tsev hluav taws siv ib qho kev sib tw sib txuas los tiv thaiv vuam los ntawm kev ua kom lub galvanized txheej.

A:
Galvanizing: Pa kev tiv thaiv Corrosion, haum rau cov chaw noo noo (xws li hauv qab no);
Epoxy Resin txheej: Tshuaj lom neeg kuj, siv rau cov nroj tsuag tshuaj;
Phab ntsa sab nraud txheej: faus kav dej yuav tsum muaj kev tiv thaiv kev tiv thaiv hluav taws xob 3PE corrosion (xws li kev tiv thaiv hluav taws sab nraum zoov cable).
Piv txwv li, cov kav dej tua hluav taws hauv cov tshuaj nroj tsuag muaj kev tiv thaiv nrog ob txheej ob txheej ntawm galvanizing thiab epoxy cob qhia thiab epoxy cob.
4. Q: Tus tsim tsim ua tiav li cas ntawm hluav taws tua hluav taws xob tiv thaiv steel pipes txiav txim siab?
A: Nws nyob ntawm qhov system hom:
Hluav Taws hydrant Systems feem ntau 1.0-1.6 mpa;
Sprinkler cov tshuab muaj siab - qhov chaw siab tshaj 2.5 MPa.
Piv txwv li, cov yeeb nkab steel tsim siab rau qhov siab - qhov siab water pop system nyob rau hauv ib qho chaw siv cov ntaub ntawv yog 3.0 MPa, thiab Sch80 seamless steel yeeb nkab siv.
5. Q: Cov txheej txheem txais kev lees txais rau cov txheej txheem hluav taws tiv thaiv hlau hluav taws xob tsis tiv thaiv?
A: Cov qauv hauv qab no yuav tsum tau ntsib:
GB / T 3091 {{- 2015 (galvanized welded steel kav rau kev thauj khoom qis qis);
GB 50974 {-} 2014 (Kev qhia txuj ci tshwj xeeb rau kev tua hluav taws-tua hluav taws thiab hluav taws kub system);
Kev ntsuam xyuas hydraulic: 1.5 zaug lub siab ua haujlwm, tswj hwm 30 feeb nrog tsis muaj xau.
