1. Kuv yuav ua li cas yog tias kuv cov yeeb nkab raug thaiv?
Blockages feem ntau yog vimav, khib nyiab, los yog mineral buildup. Koj tuaj yeem sim yaug lub kaw lus nrog dej huv lossis cua. Rau cov ntxhia nplai, siv cov tshuaj descaling yuav tsim nyog. Yog tias qhov teeb meem tshwm sim, ntu cuam tshuam yuav tsum tau hloov -5.
2. Kuv yuav xaiv cov yeeb nkab zoo li cas rau kuv qhov project?
Koj yuav tsum xav txog ntau yam tseem ceeb: lubhom ntawv thov(structural, pressurized, underground), yuav tsum tauyeeb nkab loj (NPS) thiab phab ntsa thickness (Schedule), covqib khoom sivraws li lub zog thiab kub xav tau, thiab lwm yamdaim ntawv pov thawj xav tau(piv txwv li, zeb- ntawv pov thawj rau kev ua raws cai) -1.
3. Dab tsi yog qhov sib txawv ntawm cov yeeb nkab siab thiab cov yeeb nkab qauv?
Lub cev muaj zogyog tsim thiab ntawv pov thawj kom ua tau raws li qhov tshwj xeeb siab thiab ntsuas kub rau kev nyab xeeb siv hauv cov tshuab xws li roj thiab roj kis.Cov yeeb nkabyog siv rau nws cov khoom siv kho tshuab xws li lub zog thiab nruj hauv kev siv xws li piling, fencing, thiab kev txhawb nqa, thiab tej zaum yuav tsis raug lees paub rau lub siab sab hauv -1.
4. Dab tsi yog cov yeeb nkab kawg tiav thiab cov kev pabcuam fabrication?
Cov neeg muab khoom siv feem ntau muab cov kev pab cuam tsim los ua cov yeeb nkab installation - npaj. Cov no suav nrogtxiav mus rau qhov ntev, beveling(npaj npoo rau vuam),xov(rau cov ntsia hlau txuas), thiabzawv zawg(rau mechanical couplings) -1.
5. Cov ntaub ntawv dab tsi uas kuv yuav tsum tau thov los ntawm kuv tus neeg muab cov yeeb nkab?
Txhawm rau kom muaj kev ruaj ntseg zoo, koj yuav tsum thov qhovMill Test Report (MTR), cov ntaub ntawv pov thawj ntawm kev ua raws li tus qauv txiav txim (xws li API 5L, ASTM A106), thiab, yog tias muaj, cov txiaj ntsig ntawm ib qho Kev Ntsuas Tsis Zoo (NDT) zoo li ultrasonic lossis radiographic xeem -10.
