Cov Qhov Kawg - Siv Rau Cov Pob Qij Sib Koom Tes

Dab tsi yog ib qhoqhov kawg ntawm lub qiathiab vim li cas yuav tsum siv nws? Cov kawg ntawm cov kav dej yog cov khoom siv sib txuas uas siv tau (ua ke nrog lub flange sib koom ua ke) es tsis txhob vuam cov flanges caj dab los ua cov kev sib txuas flanges. Kev siv cov kawg ntawm cov kav dej muaj ob qhov zoo: nws tuaj yeem txo tag nrho cov nqi ntawm cov pob qij txha flanges rau cov kab ke hauv cov khoom siv siab (vim tias lub flange sib koom ua ke tsis tas yuav yog cov khoom siv ntawm cov yeeb nkab thiab qhov kawg ntawm cov kav dej tab sis tuaj yeem yog qib qis dua);nws ua kom cov txheej txheem teeb tsa sai dua, vim tias lub flange sib koom ua ke tuaj yeem tig tau los pab txhawb kev sib dhos ntawm cov qhov ntsia hlau. Cov kawg ntawm cov ntsia hlau muaj nyob rau hauv cov qauv luv thiab ntev (ASA thiab MSS stub kawg), hauv qhov ntau thiab tsawg txog li 80 ntiv tes.

HOM QHIA TXOG QHOB

Cov qhov kawg ntawm cov ceg muaj peb hom sib txawv, hu ua "Hom A", "Hom B" thiab "Hom C":

• Hom thawj (A) yog tsim thiab tshuab kom phim tus qauv lap joint backing flange (ob yam khoom yuav tsum tau siv ua ke). Cov nplaim mating muaj cov qauv zoo sib xws kom tso cai rau kev thauj khoom du ntawm lub ntsej muag flare.
• Cov kawg ntawm cov pob qij txha hom B yuav tsum tau siv nrog cov flanges uas muaj qhov sib txuas ua ke
• Hom C stub kawg tuaj yeem siv nrog lub lap joint lossis slip-on flanges thiab yog tsim los ntawm cov kav dej

COV QAUV LUV/NTEV (ASA/MSS)

Cov qhov kawg ntawm cov stub muaj nyob rau hauv ob hom sib txawv:

• tus qauv luv luv, hu ua MSS-A stub ends
• tus qauv ntev, hu ua ASA-A stub ends (lossis ANSI length stub end)
