Ishadi Lobukhulu Bepayipi Le-PVC: Osayizi, i-OD, Ukuqina Kodonga & Namazinga

Ubukhulu bepayipi le-PVC behlela ezintweni ezintathu: ububanzi bangaphandle (OD), ukushuba kodonga kanye nezinga ipayipi elenzelwe lona. Lo mhlahlandlela unikeza amashadi obukhulu obuphelele be-Huasheng industrial PVC-U kanye nepayipi le-CPVC, enziwe kumazinga e-ASTM kanye ne-DIN/ISO/GB/T. Wonke amanani angamamilimitha.

Impendulo esheshayo: Ipayipi le-ASTM liqanjwe ngosayizi wegama ngamayintshi (1/2″ kuya ku-24″), futhi ukujiya kwalo kodonga lulandela ishejuli, i-SCH 40 noma i-SCH 80. Ipayipi le-DIN/ISO/GB/T liqanjwe ngobubanzi balo obungaphandle be-dn ngamamilimitha (dn20 kuya ku-dn800 ku-PVC200 ukuya ku-CP600 odongeni nogqinsi luka-dn), ilandela uchungechunge lwe-S. Kuwo womabili amasistimu, i-OD inquma ukuthi yikuphi ukufakwa okufanele.

Isebenza kanjani i-PVC Pipe Sizing

• Usayizi wokuzisholo (ASTM): ilebula, hhayi ukulinganisa. Ipayipi elingu-2″ line-OD engu-60.32 mm. I-OD iyafana ku-SCH 40 kanye ne-SCH 80, ngakho usayizi owodwa olingana ulingana womabili amashejuli.

• Ishejuli: I-SCH 80 inodonga olukhulu kune-SCH 40 kuwo wonke usayizi, ngakho ububanzi bayo bangaphakathi buncane.

• Uchungechunge lwe-S, i-SDR ne-PN (DIN/ISO/GB/T): inombolo engu-S ephansi isho udonga olujiyile kanye nesigaba sokucindezela okuphezulu. I-SDR i-OD ehlukaniswe ubukhulu bodonga.

• I-Inch vs millimeter: ipayipi elingu-4″ ASTM line-OD engu-114.3 mm, kuyilapho i-DIN dn110 ine-OD engu-110 mm. Azishintsheki, ngakho qhathanisa amanani angempela e-OD, hhayi amagama osayizi.

Ishadi lobukhulu bepayipi le-ASTM PVC-U (SCH 40 & SCH 80, ASTM D1785)

Izimboni zikaHuasheng Ipayipi le-PVC-U linikeza ukumelana nokugqwala, amandla omthelela aphezulu kanye nokumelana noketshezi oluphansi. Ngokusho kwekhathalogi yenkampani, ukugeleza kukhuphukela ku-30% ngaphezu kwepayipi lensimbi eliwububanzi obufanayo, kanti isisindo singaphansi kwama-20%.

Ishadi lobukhulu bepayipi le-DIN/ISO/GB/T PVC-U (dn20–dn800)

Ipayipi likaHuasheng le-DIN (ISO, GB/T) le-PVC-U limboza i-dn20 kuya ku-dn800 ochungechungeni lwe-S20 kuya ku-S4 (GB/T 4219-2008). Usayizi wegama yi-OD ngokwayo: i-dn110 ine-OD engu-110 mm. Udeshi usho ukuthi inhlanganisela ayifakiwe ohlwini.

I-SDR vs nominal pressure (PN) , ngokusekelwe ku-MRS yama-25 MPa:

Ishadi lobukhulu bepayipi le-CPVC (PVC-C).

I-CPVC yenziwa ngokuguqulwa kwe-chlorination ye-PVC resin. Ngemuva kwe-chlorination, ukuzinza kwamakhemikhali nokumelana nokushisa kukhuphuka, ngakho-ke ifanelana nemigqa eshisayo noma efuna kakhulu.

I-ASTM F441 CPVC (1/2″ ukuya ku-24″, SCH 40 & SCH 80): i-OD, ukujiya kodonga nokubekezelela kuyafana neshadi le-ASTM PVC-U ngenhla kuwo wonke usayizi. Isibonelo, i-2″ CPVC ine-OD engu-60.32 mm, udonga lwe-SCH 40 olungu-3.91 mm kanye nodonga lwe-SCH 80 olungu-5.54 mm.

I-DIN/GB/T 18998.2 CPVC (dn20–dn630, S12.5 kuya ku-S4): izindonga zihlukile ku-PVC-U, ngakho leli shadi lifakwe ohlwini ngokuhlukana.

I-SCH 40 vs SCH 80: Umehluko Obalulekile Wobukhulu

I-SCH 40 kanye ne-SCH 80 zabelana nge-OD efanayo kuwo wonke usayizi wegama, ngakho zilingana nokufakwa kwamasokhethi okufanayo. I-SCH 80 inodonga olukhulu futhi inobubanzi obuncane bangaphakathi. Igebe likhula ngosayizi: I-SCH 80 icishe ibe ngu-35% ugqinsi kune-SCH 40 ku-1/2″ futhi icishe ibe ngu-77% ukuqina ngo-24″.

Bala ububanzi bangaphakathi nge-: ID = OD − 2 × udonga . Ku-2″ ipayipi, i-SCH 40 inikeza u-60.32 − 2 × 3.91 = 52.50 mm, futhi i-SCH 80 inikeza u-60.32 − 2 × 5.54 = 49.24 mm. Lawa amanani alinganiselwe asekelwe odongeni oluncane.

Ukuze uhlonze ipayipi elingaziwa, linganisa i-OD yayo ngamakhalipha futhi uyiqhathanise namashadi: ukufunda eduze kuka-60.32 mm ngu-2″ ASTM, futhi ukufunda eduze no-110 mm kuthi DIN dn110.

Indlela Yokukhetha I-PVC Pipe Esezingeni Elifanele Nosayizi

1. Qondanisa izinga nesistimu yakho. Ipayipi, okokufakwa kanye nama-valve emgqeni owodwa kufanele kulandele izinga elifanayo.

2. Khetha usayizi nge-OD. Khumbula ukuthi i-4″ ASTM (114.3 mm) kanye ne-dn110 (110 mm) amasayizi ahlukene.

3. Khetha udonga ngokucindezela. Sebenzisa i-SCH 80 odongeni olujiyile kupayipi le-ASTM, noma inombolo ephansi engu-S kupayipi le-DIN/ISO/GB/T.

I-Huasheng iphinde yenza ibhola le-PVC, uvemvane, isheke, phansi, i-diaphragm nama-valve okusampula ukuze ahambisane nobubanzi bepayipi ngalinye. Lesi sihloko sibala ubukhulu kuphela. Ngesilinganiso sokucindezela sosayizi othize, cela i-Huasheng idatha yobuchwepheshe.

I-PVC Pipe Dimensions FAQs

1.Yimaphi amasayizi amapayipi e-PVC ajwayelekile?
Ipayipi le-ASTM ligijima lisuka ku-1/2″ liye ku-24″ ku-SCH 40 kanye ne-SCH 80. I-DIN/ISO/GB/T PVC-U isebenzisa i-dn20 iye ku-dn800, futhi i-CPVC isuka ku-dn20 iye ku-dn630.

2.Iyini i-OD yepayipi le-PVC lama-intshi angu-2?
60.32 mm (±0.15 mm) kukho kokubili i-SCH 40 ne-SCH 80. Udonga luyi-3.91 mm ku-SCH 40 kanye no-5.54 mm ku-SCH 80.

3.Ingabe i-SCH 40 ne-SCH 80 zisebenzisa ukufakwa okufanayo?
Yebo. Zine-OD efanayo kusayizi ngamunye wegama. Ukujiya kodonga kuphela nobubanzi bangaphakathi kuyahluka.

4.Imuphi usayizi wepayipi le-PVC elingu-110 mm ngama-intshi?
Cishe 4.33 amayintshi. Ayifani nepayipi elingu-4″ ASTM, eline-OD engu-114.3 mm.

5.Uyini umehluko phakathi kwe-PN10 ne-SDR21?
I-SDR21 wuchungechunge lwe-S10. Inikeza ukucindezela okulinganiselwe kwe-1.0 MPa (ibha engu-10) ku-C = 2.5 no-1.25 MPa ku-C = 2.0, ngokusekelwe ku-MRS yama-MPa angu-25.

6.Ingabe ubukhulu be-PVC-U ne-CPVC buyafana?
Ngepayipi le-ASTM, yebo. Ngepayipi le-DIN/ISO/GB/T banamashadi ahlukene: I-PVC-U ihlanganisa i-S20 kuya ku-S4 kufika ku-dn800, futhi i-CPVC ihlanganisa i-S12.5 kuya ku-S4 kufika ku-dn630.
