Copper DWV Piping
Qhov zoo tshaj plaws rau: Qee zaus siv rau DWV (drain-waste-vent) pipes.Copper pipes for pipes drains and vents was used in many old homes and commercial applications, but it has been all but replaced with PVC or ABS yas yeeb nkab nyob rau hauv niaj hnub siv. (Rau cov ntawv tshwj xeeb lossis kev siv, xyuas koj cov cai hauv zos.) Nws tsuas yog tsim nyog rau cov ntawv thov saum toj no thiab muaj qhov ntsuas qis qis; Nws tsis tuaj yeem nqa dej siab ntawm cov dej hauv nroog feem ntau.DWV yeeb nkab feem ntau muaj cov cim daj kom paub qhov txawv ntawm lwm hom.
Qhov zoo tshaj plaws rau:Qee zaum siv rau DWV (drain-waste-vent) kav.
Cov yeeb nkab tooj liab rau cov kav dej thiab cov vents tau siv nyob rau hauv ntau lub tsev qub thiab kev lag luam, tab sis nws tau tag nrho tab sis hloov nrog PVC lossis ABS yas yeeb nkab hauv kev tsim kho niaj hnub. (Rau cov ntawv tshwj xeeb lossis kev siv, xyuas koj cov cai hauv zos.) Nws tsuas yog tsim nyog rau cov ntawv thov saum toj no thiab muaj qhov ntsuas qis qis; nws tsis tuaj yeem nqa dej siab ntawm feem ntau cov dej hauv nroog.
DWV yeeb nkab feem ntau muaj cov cim daj kom paub qhov txawv ntawm lwm hom.
Xaiv cov yeeb nkab tooj liab
Cov kav dej tooj liab (feem ntau hu ua tubing) los ntawm ntau hom raws li qhov tuab ntawm cov phab ntsa hauv cov yeeb nkab txheeb ze rau txoj kab uas hla ntawm cov yeeb nkab. Raws li tau hais los saum toj no, xaiv txoj cai tooj liab yeeb nkab yog ib qho teeb meem ntawm kev sib piv cov thickness ntawm cov yeeb nkab phab ntsa rau cov kev xav tau ntawm daim ntawv thov. Hom K muaj qhov loj tshaj plaws ntawm phab ntsa-thickness rau cov yeeb nkab txoj kab uas hla thiab feem ntau yog siv rau cov ntawv siv hauv av uas xav tau lub zog loj. Ntawm qhov kawg, DWV qib muaj qhov qis tshaj phab ntsa-thickness rau cov yeeb nkab txoj kab uas hla, ua rau nws tsuas yog tsim rau cov kav dej thiab qhov cua uas tsis muaj qhov siab. Nyob rau hauv nruab nrab, Hom L thiab M yog cov kav dej feem ntau siv rau cov kav dej hauv cov kav dej. Hauv cov ntsiab lus: 2
DWV-grade:Nrog rau phab ntsa tuab ntawm 0.42 nyob rau hauv. rau 1 1/2-inch yeeb nkab, qib ntawm cov yeeb nkab tooj liab no tau pom zoo rau saum toj thiab hauv qab-hauv av ntws, pov tseg, thiab cov kav dej. Txawm li cas los xij, muab cov nqi ntawm tooj liab, nws tsis tshua muaj kev xaiv tooj liab DWV yeeb nkab thaum PVC thiab ABS yas yog li pheej yig dua thiab ua haujlwm yooj yim dua. Ib qho kev zam yuav yog nyob rau hauv qhov chaw raug, tshwj xeeb tshaj yog cov tsev vintage uas yuav tsum tau ua raws li keeb kwm kev coj ua.
