Nyob ntawm lub hom phiaj thiab cov khoom siv yeeb nkab, feem ntau siv txoj kev sib txuas rau kev tsim cov kav hlau muaj xws li threaded kev twb kev txuas, flange kev twb kev txuas, vuam, groove kev twb kev txuas (clamp kev twb kev txuas), ferrule kev twb kev txuas, compression kev twb kev txuas, kub yaj kev twb kev txuas, socket kev twb kev txuas, thiab lwm yam.

1. Threaded kev twb kev txuas: Threaded kev twb kev txuas yog tsim los ntawm kev siv threaded steel yeeb nkab fittings. Galvanized steel kav nrog ib tug yeeb nkab txoj kab uas hla ntawm tsawg dua los yog sib npaug zos rau 100 hli yuav tsum tau txuas nrog ib tug threaded kev twb kev txuas, thiab feem ntau yog siv rau nto-mounted steel kav. Steel-yas composite kav kuj feem ntau txuas nrog threads. Galvanized steel kav yuav tsum tau txuas nrog threads. Qhov saum npoo ntawm txheej txheej galvanized thiab cov xov xov uas raug puas tsuaj thaum threading cov xov yuav tsum tau kho nrog kev tiv thaiv corrosion. Flanges lossis ferrule-hom tshwj xeeb yeeb nkab fittings yuav tsum tau siv rau kev sib txuas. Cov welds ntawm galvanized steel kav thiab flanges yuav tsum yog Secondary galvanizing.

2. Flange kev twb kev txuas: Flange kev twb kev txuas yog siv rau steel kav nrog loj diameters. Flange kev sib txuas feem ntau yog siv rau hauv cov kav dej loj los txuas cov li qub, kos li qub, cov ntsuas dej, cov twj tso dej, thiab lwm yam, nrog rau cov kav dej uas yuav tsum tau nquag disassembly thiab tu. Yog tias cov kav dej galvanized txuas nrog vuam los yog flange, cov vuam sib txuas yuav tsum yog qhov thib ob galvanized lossis tiv thaiv corrosion.

3. Vuam: Vuam yog tsim rau cov kav hlau tsis muaj galvanized. Nws feem ntau yog siv los zais cov kav hlau thiab cov kav hlau uas muaj qhov loj dua thiab siv dav hauv cov tsev siab. Cov pob qij txha tshwj xeeb lossis vuam siv tau los txuas cov kav dej. Thaum cov yeeb nkab txoj kab uas hla tsawg dua 22 hli, lub qhov (socket) lossis casing vuam yuav tsum tau siv. Lub qhov (socket) yuav tsum tau muab ntsia rau ntawm qhov ntws ntawm qhov nruab nrab. Thaum cov yeeb nkab txoj kab uas hla ntau dua los yog sib npaug li 2 hli, pob tw vuam yuav tsum tau siv. Cov kav hlau tsis muaj steel tuaj yeem ua tau welded.

4. Grooved kev twb kev txuas (clamp kev twb kev txuas): grooved connector yuav siv tau rau galvanized steel kav nrog diameters ntau tshaj los yog sib npaug zos rau 100 hli nyob rau hauv cov dej tua hluav taws, cua txias dej kub thiab txias, dej mov, dej nag, thiab lwm yam systems. Nws yooj yim rau kev khiav lag luam thiab tsis cuam tshuam rau cov yeeb nkab steel. Cov yam ntxwv qub ntawm cov kav dej, yog kev tsim kho kom zoo, kev ruaj ntseg zoo, kev saib xyuas yooj yim, txuag kev ua haujlwm thiab sijhawm, thiab lwm yam.

5. Daim npav lub tes tsho txuas: Aluminium-yas cov kav dej feem ntau siv cov tes tsho clamp rau crimping. Tso cov txiv ntseej uas haum rau ntawm qhov kawg ntawm cov yeeb nkab steel, tom qab ntawd muab tso sab hauv ntawm qhov haum mus rau qhov kawg, thiab siv lub wrench kom nruj li qhov haum thiab txiv ntoo. Cov kav dej tooj liab kuj tseem tuaj yeem txuas nrog siv threaded ferrules.

6. Xovxwm-haum kev sib txuas: Stainless hlau xovxwm-hom yeeb nkab fittings kev sib txuas tshuab hloov cov khoom siv dej ib txwm siv steel yeeb nkab kev sib txuas thev naus laus zis xws li threading, vuam, thiab cov nplaum nplaum. Nws muaj cov yam ntxwv ntawm kev tiv thaiv dej zoo thiab kev nyiam huv, muaj zog corrosion kuj, thiab kev pab lub neej ntev. Nws yuav siv thaum lub sij hawm tsim kho. Lub qhov (socket) yeeb nkab fittings nrog tshwj xeeb sealing rings yog txuas nrog cov yeeb nkab steel, thiab cov cuab yeej tshwj xeeb yog siv los ua kom cov yeeb nkab lub qhov ncauj kaw kom nruj thiab nruj. Nws muaj qhov zoo ntawm kev yooj yim installation, txhim khu kev qha kev sib txuas, thiab kev siv nyiaj txiag thiab tsim nyog.

7. Kub yaj kev sib txuas: Txoj kev sib txuas ntawm cov kav dej PPR siv cov kub melter rau kub yaj txuas.

8. Kev sib txuas ntawm lub qhov (socket): siv rau kev sib txuas cov kav dej cam khwb cia hlau thiab fittings rau cov khoom siv dej thiab cov kav dej. Muaj ob hom: kev sib txuas yooj yim thiab kev sib txuas tsis zoo. Kev sib txuas yooj yim yog kaw nrog lub nplhaib roj hmab, thaum cov kev sib txuas tsis sib haum yog kaw nrog cov asbestos cement lossis cov khoom siv ntxiv. Lead sealing tuaj yeem siv rau hauv cov xwm txheej tseem ceeb.
