PPR yeeb nkab specifications qhia siv yeeb nkab series S, nominal txheej kab dn × nominal phab ntsa thickness en.
Piv txwv li: PPR yeeb nkab series S5, PPR nominal txheej txoj kab uas hla dn 25mm, PPR nominal phab ntsa thickness en 2.5mm, qhia raws li S5, dn 25 × en 2.5mm.
PPR yeeb nkab series S: Ib tug dimensionless tooj series siv los sawv cev PPR yeeb nkab specifications, nrog rau cov nram qab no kev sib raug zoo: S=(dn - en) / 2 en
Qhov twg: dn-PPR nominal txoj kab uas hla (sab nraud txoj kab uas hla), nyob rau hauv mm en - PPR nominal phab ntsa thickness, nyob rau hauv mm
Feem ntau siv PP-R yeeb nkab specifications muaj xws li tsib series: 5, 4, 3.2, 2.5, thiab 2.
PPR yeeb nkab specifications kuj categorized ua tsib series raws li Standard Dimension Rate (SDR): 11, 9, 7.4, 6, thiab 5.
PPR Standard Dimension Rate (SDR): Qhov piv ntawm nominal txheej kab uas hla dn rau nominal phab ntsa thickness en ntawm cov yeeb nkab PPR.
Kev sib raug zoo ntawm PPR yeeb nkab specification SDR thiab PPR yeeb nkab series yog raws li nram no: SDR=2S + 1
Txoj kev sawv cev ntawm PPR yeeb nkab haum specifications:
Lub nominal sab nraud txoj kab uas hla dn ntawm ib tug PPR yeeb nkab haum yog hais txog lub nominal txheej kab ntawm lub PPR yeeb nkab txuas nrog lub haum. Phab ntsa thickness ntawm PPR haum yuav tsum tsis txhob tsawg tshaj li phab ntsa thickness ntawm PPR yeeb nkab ntawm tib series S.
Cov tuam txhab lag luam feem ntau tsuas muaj ib qho ntawm PPR yeeb nkab fittings, tus qauv siab tshaj S2, uas yog tsim rau ob qho tib si dej kub thiab dej txias.
PPR yeeb nkab specification S5 series: 1.25 MPa (12.5 kg)
PPR yeeb nkab specification S4 series: 1.6 MPa (16 kg)
PPR yeeb nkab specification S3.2 series: 2.0 MPa (20 kg)
PPR yeeb nkab specification S2.5 series: 2.5 MPa (25 kg)
