Tau tshaj tooj liab: Ib khub ntseeg
Brass yeeb nkab fittingsthiab cov kav dej tooj liab tau sib haum xeeb. Ob leeg yog tooj liab-raws li alloys, yog li lawv sib piv cov khoom siv hluav taws xob zoo sib xws. Qhov no ua rau lawv yog ib khub zoo tagnrho rau cov tsev nyob thiab kev lag luam kav dej.
Vim li cas tooj dag thiab tooj liab ua haujlwm ua ke
Electrochemical compatibility yog qhov laj thawj tseem ceeb. Qhov sib txawv voltage ntawm tooj dag thiab tooj liab yog tsawg heev. Daim ntawv qhia kev lag luam sau tseg tias qhov kev ua galvanic nruab nrab ntawm lawv yog ntsuas raws li "tsis tseem ceeb". Yog li ntawd, lawv yuav tsis corrode ib leeg.
Yuav ua li cas txuas tooj dag rau tooj liab
Txuas tooj dag rau tooj liab yog qhov yooj yim heev. Feem ntau koj siv ib tug threaded adapter. Cov tooj dag haum muaj poj niam threads. Lub tooj liab adapter muaj txiv neej threads. Koj siv Teflon daim kab xev thiab ntsia hlau lawv ua ke. Cov kws tshaj lij kav dej siv txoj kev no txhua hnub.
Brazing rau Permanent Joints
Rau kev sib koom ua ke mus tas li, brazing yog ib qho kev xaiv. Cov txheej txheem European qhia txog tooj liab alloy fittings rau brazing rau tooj liab raj. Cov tshuab no yog tsim los rau lub neej ua haujlwm txog li tsib caug xyoo. Qhov no tsim kom muaj kev sib koom ua ke muaj zog heev.
Brass rau PVC: Siv Threaded Adapters
Brass yeeb nkab fittingstsis ncaj qha rau PVC. Koj tsis tuaj yeem ua kua nplaum lossis fuse lawv. Txawm li cas los xij, tshwj xeeb "PVC tshaj" tooj dag fittings muaj nyob. Cov adapters no muaj cov qauv PVC xov ntawm ib sab. Cov tooj dag sab muaj tus qauv NPT xov rau dej.
Risk ntawm Direct Threading
Koj yuav tsum tsis txhob threading tooj dag haum ncaj qha rau hauv cov yas poj niam haum. Yas yog softer dua hlau. Tshaj -tighten lub tooj dag yuav tawg lub cev PVC . Ib lub rooj sab laj uas paub txog tau ceeb toom tias, "koj yuav xav rov xav txog lub tswv yim ntawd." Ib txwm siv cov kev hloov pauv kom raug.
Lub luag haujlwm ntawm Dielectric Unions
Cov koom haum dielectric tsis tshua xav tau rau tooj dag- mus rau - tooj liab pob qij txha. Lawv yuav tsum tau sib txuas cov hlau sib txawv xws li hlau thiab tooj liab. Txij li cov tooj dag thiab tooj liab yog metallurgically kaw, tsis xav tau kev sib cais.
Siv Brass Push-Fit Fittings
Niaj hnub thawb- haum fittings daws teeb meem kev sib raug zoo tam sim ntawd. Sab hauv tsim siv lub nplhaib stainless hlau tuav los tuav cov yeeb nkab. Tib yamtooj dag fittingstuaj yeem txuas rau tooj liab, PEX, lossis CPVC. Tsis tas yuav siv cov cuab yeej, kua nplaum, los yog soldering.
Cov qauv rau kev hloov pauv Fittings
Tub rog thiab cov qauv kev lag luam txhawb cov ntawv thov no. A-A-59617 specification suav nrog cov koom haum tooj dag rau kev koom nrog cov yeeb nkab thiab cov yeeb nkab. Lawv yog "tshaj nrog tus qauv hnyav tooj liab lossis tooj dag yeeb nkab". Qhov no suav nrog compatibility nrog cam khwb cia tooj liab thiab wrought tooj liab.
Yuav ua li cas txog Flare thiab Compression?
Brass compression fittings yog sib xws nrog tooj liab tubing. Lawv ua haujlwm nrog cov tooj liab tawv thiab mos tooj liab coils. Rau PVC, koj xav tau tooj dag-rau-PVC hloov pauv hloov pauv ua ntej, tom qab ntawd sab compression.
Kev ceeb toom tshuaj lom neeg rau PVC kua nplaum
PVC hnyav cement yog qhov txaus ntshai rau tooj dag. Cov tshuaj tuaj yeem ua rau cov hlau puas. Ib lub chaw tsim khoom ceeb toom tawm tsam qhov raug "PVC kua nplaum, cov kuab tshuaj, cov cements". Khaws PVC primer kom deb ntawm polished tooj dag.
Cov ntsiab lus ntawm Compatibility
Brass yeeb nkab fittingsyog tag nrho sib xws nrog tooj liab thiab tuaj yeem hloov tau yooj yim rau PVC. Koj xav tau ib tug threaded hloov adapter mus txuas rau cov kav dej yas. Tsis txhob ncaj threading los tiv thaiv kev tawg ntawm PVC. Siv cov koom haum dielectric nkaus xwb rau cov hlau, tsis yog tooj liab. Txhawm rau kho sai, siv lub laub- haum tooj dag fittings uas tuav ob qho tib si hauv .
