Muaj ntau tus neeg siv khoom xav tau cov yeeb nkab steel hauv ob xyoos dhau los. Niaj hnub no peb yuav kawm txog covwelding txoj kev ntawm cov yeeb nkab spools.

Raws li kev siv thiab cov yeeb nkab, feem ntau siv txoj kev sib txuas yog: xov txuas, flange kev twb kev txuas, vuam, groove kev twb kev txuas (clamp kev twb kev txuas), lub tes tsho hom kev twb kev txuas, compression kev twb kev txuas, kub yaj kev twb kev txuas, socket kev twb kev txuas, thiab lwm yam.

1.Flange kev twb kev txuas

Cov kav dej uas muaj cov kab loj loj txuas nrog flanges, feem ntau yog siv los txuas cov valve, kos li qub, ntsuas dej, cov twj tso kua dej thiab lwm qhov chaw hauv txoj kev loj, nrog rau cov kav dej uas yuav tsum tau muab tshem tawm thiab kho tsis tu ncua. Yog hais tias galvanized yeeb nkab yog welded los yog flanged, qhov chaw vuam yuav tsum tau galvanized los yog anticorrosive ob zaug.

2.Qhov vuam

Vuam yog tsim rau cov yeeb nkab uas tsis yog-galvanized steel, feem ntau yog siv rau cov yeeb nkab zais thiab cov yeeb nkab loj, thiab ntau daim ntawv thov hauv cov tsev siab. Kev sib koom tes tshwj xeeb lossis vuam siv tau rau kev sib txuas ntawm cov yeeb nkab tooj liab. Thaum cov yeeb nkab txoj kab uas hla tsawg dua 22 hli, lub qhov (socket) lossis lub tes tsho vuam yuav tsum tau siv. Lub qhov (socket) yuav tsum tau muab ntsia kom tau raws li qhov ntws ntawm qhov nruab nrab. Stainless hlau yeeb nkab tuaj yeem yog qhov (socket) vuam.

3.Threaded kev twb kev txuas

Threaded kev twb kev txuas yog siv cov threaded yeeb nkab fittings kev twb kev txuas, yeeb nkab txoj kab uas hla yog tsawg dua los yog sib npaug zos rau 100 hli galvanized steel yeeb nkab yuav tsum tau txuas nrog threads, siv nyob rau hauv qhib installation pipeline. Hlau - yas puas yeeb nkab feem ntau txuas nrog xov. Galvanized steel yeeb nkab yuav tsum tau txuas nrog xov. Qhov saum npoo ntawm galvanized txheej puas los ntawm xov teeb yuav tsum tau kho nrog kev tiv thaiv corrosion. Flange lossis clamp lub tes tsho tshwj xeeb cov yeeb nkab fittings yuav tsum tau siv rau kev sib txuas, thiab qhov chaw vuam ntawm galvanized steel yeeb nkab thiab flange yuav tsum tau galvanized ob zaug.

4.Socket kev twb kev txuas

Siv rau kev sib txuas cov kav dej cam khwb cia hlau thiab fittings rau cov dej thiab cov dej ntws. Muaj ob hom kev sib txuas yooj yim thiab kev sib txuas tsis sib xws. Kev sib txuas yooj yim yog kaw nrog lub nplhaib roj hmab, thiab kev sib txuas tsis sib xws yog kaw nrog asbestos cement lossis expansive packing. Cov hmoov txhuas tuaj yeem siv rau lub sijhawm tseem ceeb.

Peb cov yeeb nkab spools tau siv rau hauv cov haujlwm loj hauv ntau lub teb chaws, yog tias koj xav tau lawv, thov xa koj cov lus nug rau peb.
