Kev kub siab Stainless hlau PPR haum

Yuav tsum tau kos npe rau ntawm PPR qhov (socket).

Txhua daim ntawv pov thawj stainless hlau PPR haum yuav tsum muaj cov cim tas mus li ntawm PPR qhov (socket). Nrhiav cov hauv qab no: tus qauv siv (ISO 15874 rau cov dej haus), nominal txoj kab uas hla (xws li, DN20, DN25), SDR tus nqi (xws li, SDR 11, SDR 9) los yog PN ntsuam xyuas (PN16, PN20, PN25), cov khoom siv code (PP-R lossis PP{{14} lub npe chaw tsim khoom) lossis RCT. Cov cim no feem ntau yog embossed los yog luam tawm nrog cov cua sov- tus cwj mem resistant. Yog tias cov cim ploj lawm, tsis pom zoo, lossis pom tias yog qhov chaw-tsuas yog (tej zaum yuav rub tawm), tsis lees txais qhov haum. Cov fittings cuav feem ntau tsis muaj cov ntaub ntawv pov thawj ISO zoo lossis muaj qhov ntsuas PN tsis raug.

Stainless Hlau Qib Markings

Lub stainless hlau ntxig yuav tsum tau cim nrog qib - "304" los yog "316" - feem ntau stamped rau ntawm hex flats los yog ntawm lub ntsej muag xov. Qee cov tuam txhab lag luam kuj stamp tus qauv xov ("BSP" lossis "NPT"). Yog tias tsis pom daim ntawv pov thawj qib, thov daim ntawv pov thawj khoom siv (MTC) los ntawm tus muag khoom. MTC yuav tsum qhia cov tshuaj muaj pes tsawg leeg: rau 304, Cr 18-20%, Ni 8-10.5%; rau 316, Cr 16-18%, Ni 10-14%, Mo 2-3%. Tsis muaj lub thwj lossis daim ntawv pov thawj, tsis txhob xav tias qib - ntau cov khoom siv qis qis siv qib 201 lossis 202 stainless, uas muaj kev tiv thaiv corrosion qis dua thiab tuaj yeem xeb sai sai.

Kev Tshawb Fawb Txog Lub Cev Lub Cev

Tshawb xyuas tag nrho qhov haum rau qhov tsis xws luag. PPR lub qhov (socket) yuav tsum muaj qhov du, zoo ib yam tsis muaj npuas, dub specks, lossis tawg. Lub stainless hlau ntxig yuav tsum tau ruaj ntseg embedded - sim twist nws nrog pliers; nws yuav tsum tsis txhob tig los yog rub tawm. Cov xov yuav tsum huv si, tag nrho tsim, thiab tsis muaj burrs lossis puas. Qhov chaw hloov pauv uas cov hlau tsis muaj hlau tau ntsib PPR yuav tsum tsis muaj qhov khoob - ib qho kev sib txawv pom tau hais tias tsis zoo molding thiab muaj peev xwm xau txoj hauv kev. Rau electrofusion- hom PPR fittings (tsis tshua muaj rau stainless), tshuaj xyuas cov cua sov coil kev ncaj ncees.

Dimensional Checks - Qhov tob tob thiab xov haum

Ua ntej installation, ua ib qho yooj yim haum check. Ntxig qhov sib txuam PPR yeeb nkab rau hauv lub qhov (socket) PPR los ntawm tes - nws yuav tsum nkag mus rau hauv qhov tsis muaj zog thiab ncav cuag lub qhov (socket) hauv qab. Ntsuas qhov tob ntawm qhov (socket) (nws yuav tsum ua raws li cov chaw tsim khoom tshwj xeeb). Rau sab threaded, sim cov xov haum nrog ib tug paub zoo mating tivthaiv los yog ib tug xov gauge. Rau NPT los yog BSPT threads, qhov haum yuav tsum xov ntawm tes rau tsawg kawg 2-3 lem ua ntej zawm. Yog tias nws khi tam sim ntawd, cov qauv xov yuav tsis sib haum (xws li, NPT haum nrog BSP mating tivthaiv). Yog hais tias threads yog xoob heev, qhov haum yog tawm ntawm specification.

Kev ntsuas siab thiab cov ntaub ntawv

Rau kev teeb tsa tseem ceeb (cov tsev lag luam, roj av, siab - dej siab), ntsuas ntsuas txhua qhov haum ua ntej zais. Ua ntsuas hydrostatic ntawm 1.5x ua haujlwm siab rau yam tsawg kawg 30 feeb. Cov ntaub ntawv xeem tau nrog cov duab ntawm lub ntsuas siab thiab kev teeb tsa. Khaws cov lej batch thiab MTCs hauv ib qhov project file - cov no yog qhov tseem ceeb rau kev lees paub. Yog tias ib qho kev sib haum tsis ua tiav qhov kev ntsuas siab, txiav nws tawm thiab khaws cia rau kev ntsuas tsis ua haujlwm. Tus neeg muag khoom muaj npe nrov yuav hloov cov khoom siv tsis tau thiab tshawb xyuas qhov ua rau.

Red Flags - Thaum Yuav Tsis Pom Zoo

Tsis lees txais lub stainless hlau PPR haum tam sim ntawd yog tias muaj cov xwm txheej no tshwm sim: ploj lossis tsis pom zoo ISO 15874 kos npe, tsis muaj PN lossis SDR cim, tsis muaj stainless hlau qib stamp, ntxig spin lossis txav, pom tawg hauv PPR lub qhov (socket), xov puas (hla - xov, nco ncov), xeb lossis xeb ntawm cov ntawv pov thawj tsis ncaj ncees lawm, tsis muaj cov ntaub ntawv pov thawj ntawm cov hlau tsis muaj steel hlau. Tsis tas li ntawd tsis lees paub yog tias tus nqi qis dua li qhov nruab nrab ntawm kev ua lag luam - cov khoom cuav feem ntau siv cov yas tsis zoo los yog qis- qib stainless uas yuav corrode nyob rau hauv lub hlis.

Cov ntsiab lus

Txheeb xyuas cov hlau tsis zoo PPR fittings los ntawm kev txheeb xyuas ISO 15874, PN/SDR, thiab PP-R cov cim ntawm lub qhov (socket) PPR; "304" los yog "316" stamp ntawm stainless hlau ntxig; ruaj ntseg embedment (tsis muaj kev sib hloov); smooth PPR nto; thiab xov zoo haum. Thov cov ntaub ntawv xeem ntawv pov thawj rau kev lees paub qib. Tshem tawm cov fittings uas tsis muaj cov cim, ntxig txav, tawg, lossis xeb. Kev ntsuas siab ua ntej zais thiab khaws cov ntaub ntawv rau kev tiv thaiv.
