Fahamka Qeexitaanka Tuubada PPR

I. Horudhaca dhuumaha biyaha ee PPR

PPR (polypropylene copolymerized random) tuubo waa nooc cusub oo tuubo caag ah oo deegaanka u wanaagsan, oo leh caabbinta heerkulka sare, iska caabin daxalka, cimri dheer (ka badan 50 sanado) iyo astaamo kale, si ballaaran loo isticmaalo dhismaha hababka biyaha kulul iyo qabow, HVAC injineernimada iyo goobta gaadiidka dareeraha warshadaha. Faa'iidooyinka asaasiga ah waxaa ka mid ah:

Badbaadada iyo ilaalinta deegaanka: Aan sun ahayn oo aan ur lahayn, si waafaqsan heerarka caafimaadka biyaha la cabbo (GB/T 17219).

Iska caabbinta heerkulka xooggan: heerkulka isticmaalka muddada-dheer ee 70 ° C, U adkaysiga heerkulka muddada gaaban ilaa 95°C.

Cadaadiska iyo iska caabinta daxalka: Ma jiraan dhibaatooyin daxalka korantada, ku haboon aashitada iyo deegaanka alkali.

Ku rakibida habboon: Tignoolajiyada isku xirka dhalaalka kulul si loo gaaro xirid aan kala go 'lahayn, si meesha looga saaro khatarta daadinta.

2, qeexitaannada cabbirrada tuubooyinka biyaha PPR

1. Dhexroorka ka baxsan iyo dhumucda gidaarka

Qeexitaannada dhuumaha PPR ilaa dhexroorka bannaanka magac ahaan (dn), cabbirada caadiga ah waxaa ka mid ah:

dn20 (4-tuubo daqiiqo), dn25 (6-tuubo daqiiqo), dn32 (1-tuubo inch ah), dn40, dn50, dn63 iyo wixii la mid ah.

Dhumucda darbiga (gudaha) waxaa lagu xisaabiyaa iyadoo lagu saleynayo qiimaha SDR oo si toos ah u saameeya awoodda cadaadiska (Hoos ka eeg faahfaahinta SDR).

2. Qiimaynta cadaadiska (Qiimaha PN)

Tuubooyinka PPR waxay u qaybsan yihiin afar qaybood iyadoo loo eegayo cadaadiska magaca:

3. SDR (Heerka cabbirka caadiga ah)

SDR (Heerka cabbirka caadiga ah) waa halbeegga naqshadaynta xudunta u ah tuubada PPR, lagu qeexay saamiga dhexroorka tuubada (dn) dhumucda gidaarka (gudaha):

SDR = dhexroorka dibadda (dn) / dhumucda gidaarka (gudaha)

Qiimaha SDR wuu ka yar yahay → darbi dhumuc weyn → waa sida uu u xoog badan yahay awoodda cadaadiska, ku habboon nidaamyada cadaadiska sare.

Inta uu sii weynaado qiimaha SDR → waxaa sii dhuuban gidaarka tuubada → dhaqaale wanaagsan, ku habboon xaaladaha cadaadiska hooseeya.

Qiimaha SDR ee caadiga ah iyo qiimeynta cadaadiska u dhigma

3. Sida loo doorto si waafaqsan SDR?

1. Xulashada iyadoo loo eegayo baahida cadaadiska nidaamka

Xaalad cadaadis-sare (tusaale. Qolka kululeeyaha HVAC): dooro SDR6 ama SDR7.4 oo leh dhumuc weyn oo gidaar ah iyo iska caabin gurguurta oo xooggan.

Biyo kulul iyo qabow la deggan yahay oo caadi ah: SDR9 (PN16) kulmi karaan in ka badan 90% ee baahida.

Mashruuca biyo qabow ee jaban: SDR11 (PN10) leh dhaqaalaha ugu fiican.

2. Ku habboonaanta heerkulka

Nidaamka heerkulka sare (≥70°C): hooseeyo qiimaha SDR (tusaale. SDR7.4) waa in la doortaa si looga fogaado qallafsanaanta balaarinta kulaylka awgeed.

Nidaamka biyaha la qaboojiyey heerkulka hooseeya: Qiimaha sare ee SDR (tusaale. SDR11) waxaa loo dooran karaa si loo dhimo kharashka.

3. Tixraaca heerarka warshadaha

Heerka qaranka GB/T 18742: Tubooyinka PPR cad ee taxanaha SDR iyo shuruudaha dulqaadka cabbirka.

ISO 15874: heerka guud ee caalamiga ah, lagu dabaqi karo mashaariicda dhoofintu ku jihaysan tahay.

4, Taxaddar rakibidda tuubooyinka biyaha PPR

Xakamaynta heerkulka fiyuuska kulaylka: 260 ± 5 ° C heerkulka fiyuuska ugu fiican, si aad uga fogaato in aad sare u kacdo taasoo keenaysa kaarboonaynta walxaha.

Socket qoto dheer: u baahan tahay in la waafajiyo qeexitaannada tuubooyinka (sida tuubada dn20 qoto dheer gelinta 14mm).

Tijaabada cadaadiska: 1.5 jeer cadaadiska shaqada ee haynta cadaadiska (≥ 30 daqiiqado) ka dib markii la rakibo.

Dhuumaha biyaha ee PPR iyada oo loo marayo naqshadda sayniska ee nidaamka cabbirka SDR, si loo gaaro dheelitirka u dhexeeya waxqabadka iyo kharashka. When selecting the type, you need to integrate the three elements of system pressure, temperature and budget, and prioritize the selection of high-quality raw materials in line with the national standard (such as Scandinavian Chemical RA130E) products. As a professional manufacturer, we offer a full range of SDR-specification PPR pipes and customized solutions to help customers build safe and durable piping systems.
