Thaum nws los txog rau siab -stakes fire protection infrastructure, kev ntseeg siab ntawm koj lub piping network yog tsis muaj -xav tau.Hluav taws kub- ntsuas galvanized steel kavua lub neej ntawm cov tshuab tsis siv neeg sprinkler, hydrants, thiab standpipe tes hauj lwm. Rau cov kws tsim khoom, cov neeg ua haujlwm cog lus, thiab cov neeg tswj xyuas kev muag khoom thoob ntiaj teb, kev nkag siab txog labyrinth ntawm cov qauv thoob ntiaj teb yog thawj kauj ruam hauv kev ua kom muaj kev nyab xeeb ntawm qhov project thiab kev tswj hwm kev pom zoo. NtawmGNEE STEEL, peb lees paub tias cov yeeb nkab tsuas yog zoo li cov ntawv pov thawj nws nqa.

Lub luag haujlwm tseem ceeb ntawm Standardization hauv Kev Nyab Xeeb Hluav Taws Xob
Kev tiv thaiv hluav taws feem ntau zaum dormant rau xyoo, tab sis lawv yuav tsum ua kom tsis muaj qhov tsis zoo hauv qhov sib cais thib ob. Qhov no "standby" xwm ua rau corrosion tus yeeb ncuab ntsiag to ntawm hluav taws piping.Hluav taws kub- ntsuas galvanized steel kavyog tsim los tiv thaiv sab hauv thiab sab nraud oxidation los ntawm kev kub ceev -dip galvanizing txheej txheem. Txawm li cas los xij, lub thickness ntawm zinc txheej, cov tshuaj muaj pes tsawg leeg ntawm cov hlau, thiab lub siab - bearing peev yog tag nrho cov dictated los ntawm cov txheej txheem thoob ntiaj teb.
Ua raws li kev lees paub cov qauv ntsuas xws li ASTM, BS, thiab EN ua kom cov kav dej tuaj yeem tiv taus qhov kub ntxhov siab ntawm qhov hluav taws kub hauv cheeb tsam yam tsis muaj kev ua haujlwm tsis zoo. Tsis tas li ntawd, qhov ntev ntawm tus qauv tso cai rau kev sib txuas tsis sib haum nrog cov khoom siv sib txuas, cov li qub, thiab cov twj tso kua mis los ntawm cov tuam txhab sib txawv, txo cov teeb meem kev teeb tsa ntawm -site.
Kev sib piv kev soj ntsuam ntawm Major International Standards
Cov cheeb tsam sib txawv hais txog kev tsim khoom sib txawv. Kev xaiv tus qauv tsis raug tuaj yeem ua rau qhov kev ncua sij hawm raug nqi lossis, qhov phem dua, ua tsis tiav kev kuaj xyuas hluav taws. Hauv qab no yog ib qho kev sib cais ntawm cov qauv siv feem ntau siv rauhluav taws- ntsuas galvanized steel kavhauv kev ua lag luam thoob ntiaj teb.
Table 1: Kev Sib Piv Ntawm Cov Hluav Taws Xob Hluav Taws Xob Thoob Ntiaj Teb
| Txuj | Thaj tsam | Qib Steel | Galvanizing Requirement | Daim Ntawv Thov Kev Sib Tham |

Qhov tseem ceeb ntawm UL Listing thiab FM pom zoo
Thaum cov qauv kev tsim khoom (xws li ASTM) txhais "yuav ua li cas" cov yeeb nkab ua, thib peb -cov ntawv pov thawj zoo liUL (Underwriters Laboratories)thiabFM (Factory Global)txhais "yuav ua li cas" nws ua tau raws li hluav taws kub. Rau siab -tier ua lag luam tej yaam num, ntau lub tuam txhab tuav pov hwm tswj kev siv UL- teev los yog FM- pom zoohluav taws- ntsuas galvanized steel kav.
UL kev ntsuam xyuas tsom mus rau cov neeg kho tshuab kev ncaj ncees thiab cov nplaim hluav taws sib kis, thaum FM Ntiaj Teb tsom mus rau kev tiv thaiv kev poob thiab cov yeeb nkab muaj peev xwm ua kom muaj kev kub ntxhov siab heev (dej rauj). NtawmGNEE STEEL, peb hais ntxiv tias kev siv cov kav dej uas muaj ntawv pov thawj tuaj yeem txo qis cov nqi tuav pov hwm lub tsev thiab muab sijhawm ntev - kev kaj siab lug ntawm lub siab rau cov neeg saib xyuas cov chaw.
Technical Specifications: Txheej thiab Kev Ntsuas Siab
Kev ua tau zoo ntawm ahluav taws kub- ntsuas galvanized steel yeeb nkabFeem ntau txiav txim siab los ntawm nws cov zinc txheej loj thiab nws cov phab ntsa thickness (Schedule). Ib txheej zinc nyias yuav ua rau ntxov ntxov "pitting" corrosion, uas tuaj yeem txhaws cov dej ntws nrog cov khib nyiab.
Table 2: Zinc Txheej thiab Hydrostatic Pressure Requirements
| Pipe Class (ASTM A53 Piv txwv) | Nominal Pipe Loj (NPS) | Min. Zinc Txheej Mass | Hydrostatic Test Siab | Kev sib txuas lus pom zoo |
| Teem caij 10 | 2" - 8" | 550 g/m² | 1000 - 2500 PSI | Grooved Coupling |
| Teem caij 40 | 1/2" - 12" | 550 g/m² | 2500+ PSI | Threaded los yog Grooved |
Vim li cas cov khoom siv kev ncaj ncees tseem ceeb hauv qhov hluav taws kub ib puag ncig
Thaum muaj hluav taws kub, qhov kub hnyiab tuaj yeem tshaj 500℃hauv feeb. Tsis zoo li cov khoom siv yas,hluav taws- ntsuas galvanized steel kavtuav lawv lub zog tensile thiab tsis tso cov pa phem halogen thaum raug tshav kub. Cov txheej txheem kub -dip galvanizing tsim ib daim ntawv cog lus metallurgical- hlau-zinc alloy- uas hnyav dua li cov xim yooj yim los yog hmoov-coated nto.
Thaum muab cov khoom siv, nws yog ib qho tseem ceeb kom paub tseeb tias qhovMill Test Certificate (MTC). MTC raug cai yuav tsum taug qab cov yeeb nkab rov qab mus rau nws cov khoom siv hluav taws xob kub, lees paub cov tshuaj sib npaug ntawm Carbon, Manganese, Phosphorus, thiab Sulfur. Cov tshuaj no ua kom cov yeeb nkab ua kom zoo txaus rau grooving thiab threading yam tsis muaj kev tawg, tsis tau nruj txaus los txhawb qhov hnyav ntawm dej - puv system thoob plaws qhov dav.
Cov kev coj ua zoo tshaj plaws rau kev xa khoom thiab tshuaj xyuas
Txhawm rau kom ntseeg tau tias koj cov saw hlau tseem muaj zog, xav txog cov chaw kuaj xyuas hauv qab no thaum ntsuas tus xa khoom ntawmhluav taws- ntsuas galvanized steel kav:
- Kev tshuaj xyuas qhov muag:Xyuas kom lub bore sab hauv yog du thiab tsis muaj "zinc dross" los yog spikes uas yuav cuam tshuam cov dej ntws.
- Txheej Kev Ntsuas:Siv lub ntsuas ntsuas ultrasonic lossis sib nqus los xyuas kom meej tias zinc thickness ua tau raws li 550 g / m² (kwv yees . 65-85} microns) pib.
- End Finish Protection:Cov kav dej zoo yuav tsum tuaj nrog lub kaus mom yas lossis cov xov roj los tiv thaiv kev puas tsuaj thiab ua ntej - txhim kho xeb.
- Cov ntaub ntawv Traceability:Txhua batch yuav tsum tau nrog ISO 9001 cov ntaub ntawv tswj kev ua tau zoo thiab cov ntawv pov thawj kev nyab xeeb hluav taws.
Cov lus nug nquag nug (FAQ)
Q1: Kuv puas tuaj yeem siv cov kav dej "Pre-Galvanized" rau cov tshuab tua hluav taws?
Tsis yog. Ua ntej- cov kav dej galvanized muaj txheej txheej zinc ntau dua thiab cov npoo tsis tiv thaiv. Rau kev tiv thaiv hluav taws, tsuas yogKub-Dip Galvanized (HDG)cov kav dej raug pom zoo vim lawv qhov kev tiv thaiv corrosion zoo tshaj hauv qhov chaw ntub dej.
Q2: Vim li cas Schedule 10 yeeb nkab nrov hauv kev tiv thaiv hluav taws niaj hnub?
Teem caij 10hluav taws- ntsuas galvanized steel kavmuab qhov hnyav dua thiab loj dua sab hauv txoj kab uas hla, uas txhim kho hydraulic txaus. Thaum siv nrog grooved couplings, lawv txo cov nqi zog thaum ua tau raws li qhov tsim nyog rau kev ntsuas siab rau cov khoom lag luam feem ntau.
Q3: Cov txheej txheem galvanizing puas cuam tshuam rau vuam ntawm cov kav hluav taws xob?
Cov qauv hluav taws xob feem ntau cuam tshuam cov kav hlau galvanized vim tias cov cua sov vaporizes zinc, tsim cov pa phem thiab tawm hauv cov vuam seam yooj yim rau xeb sai. Grooved los yog threaded pob qij txha yog kev lag luam - txoj kev nyiam.
