Txuj kev piv piv. Tus txheej txheem qhov sib piv piav qhia txog kev sib txheeb ntawm cov yeeb nkab dimension thiab thickness ntawm yeeb nkab phab ntsa. Kev xaiv tsa ib txwm yog SDR11, SDR17 thiab SDR35. Cov kav dej nrog qis SDR tuaj yeem tiv taus kev siab dua.
Zoo ib yam tuaj yeem nug, SDR 11 yeeb nkab siv rau dab tsi?
PE ntau yeeb nkab cov chaw tsim khoom siv cov SDR txoj kev ntsuas siab kav . Ib SDR - 11 txhais tau tias sab nrauv (OD) ntawm yeeb nkab yog kaum ib lub sij hawm tuab ntawm phab ntsa. Nrog siab SDR piv, yeeb nkab phab ntsa yog nyias piv rau yeeb nkab txoj kab uas hla
Tsis tas li, qhov sib txawv ntawm pe80 thiab pe100 kav yog dab tsi? PE80 cev feem ntau tau ntsuas SDR11 PN12 thiab muaj qhov xav tau tsawg kawg nkaus lub zog (MRS) ntawm 8.0MPa (Megapascal). PE100 cev feem ntau tau ntsuas SDR11 PN16 thiab muaj MRS ntawm 10.0MPa, thiab feem ntau yog tsim los ntawm HDPE lossis HPPE (Kev Ua Tau Zoo Polyethylene).
Ib yam nkaus, tib neeg nug, SDR 17 yog dab tsi?
SDR yog qhov sib piv ntawm sab nraud txoj kab uas hla rau phab ntsa tuab. Rau ib qho tshwj xeeb sab nraud txoj kab uas hla, cov phab ntsa tuab tuab, qis dua SDR tus nqi, uas txhais tau tias a SDR 11 cov yeeb nkab muaj cov phab ntsa tuab dua li ib SIB 17 yeeb nkab ntawm cov kab sab nraud zoo sib xws.
SDR yeeb nkab ua los ntawm dab tsi?
Kev qhia tshwj xeeb Txhua PVC SDR Series yeeb nkab yuav tsum tau tsim los ntawm Hom I, Qib I Polyvinyl Chloride (PVC) sib xyaw nrog Kev faib tawm ntawm tes ntawm 12454 rau ASTM D1784.

SDR 11 CPVC yeeb nkab yog dab tsi?
SDR yog ib txoj hauv kev ntsuas kev ntsuas cov kav dej. SDR = D/ S qhov twg 'D' yog txoj kab uas hla thiab 'S' yog cov yeeb nkab phab ntsa tuab (hli). SDR 11 yeeb nkab yog txheej sab nraud 'D' ntawm cov yeeb nkab yog kaum ib zaug lub tuab 'S' ntawm phab ntsa txoj kab uas hla. Ib qho SDR siab dua txhais tau tias, cov yeeb nkab qis dua nrog qhov ntsuas siab tsawg dua
Qhov txawv ntawm SDR 35 thiab Teem Sijhawm 40 yeeb nkab yog dab tsi?
Txoj kab uas hla sab nrauv zoo ib yam li Teem Sijhawm 40, yog li nws tau sib xws nrog txhua Lub Sijhawm 40 thiab Teem Sijhawm 80 cov khoom siv. Siv feem ntau hauv cov cua daj cua dub thiab cov dej tso thov, SDR 35 yog cov yeeb nkab nruab nrab lub zog uas ntog ntawm Teem Sijhawm 20 thiab Sijhawm 40 PVC yeeb nkab
OD ntawm 6 SDR 35 yeeb nkab yog dab tsi?
NOMINAL PIPE SIZE (IN.) PIPE OUTSIDE DIAMETER (IN.) SDR-35 (PS 46) 6 "6.275'.180 '8" 8.400'.240' 10 "10.500'.300 '12" 12.500'.360'
CTS yeeb nkab rau dej yog dab tsi?
Copper Tube loj polyethylene yeeb nkab yog qhov me me zoo li cov yeeb nkab tooj liab thiab tseem tsim nrog Sab Nrauv Sab Hauv (OD) raws li kev tswj hwm qhov ntev. Copper Tube loj lossis CTS yeeb nkab feem ntau hu ua tubing. Hauv txhua qhov kev thov CTS qhov ntsuas siab ntawm cov yeeb nkab yuav yog 200 PSI
Dab tsi yog lub paj tawg xiav thiab paj yeeb paj yeeb?
"Blue bloaters" sawv cev rau cov uas muaj mob ntsws ntev thiab "puffers paj yeeb" sawv cev rau cov neeg mob uas mob ntsws. Cov neeg mob uas mob bronchitis yuav muaj cov tsos mob xws li ua tsis taus pa luv, hnoos ntev, ntau cov hnoos qeev thiab hawb pob uas tuaj yeem ua rau pulmonary hypertension
