Kev qhia tshwj xeeb rau kev tsim khoom thiab kev teeb tsa kev lees paub ntawm qhov cua ducts thiab accessories

1. Cov kav dej thiab fittings los ntawm thawj kaw valve mus rau qhov project qhov ncauj yuav tsum tau welded nrog steel phaj nrog ib tug tuab ntawm 2 mus rau 3 hli. Weld seam yuav tsum tag nrho, uniform thiab nruj.

2. Cov kav dej hauv qhov chaw muaj tshuaj lom yuav tsum tau txuas nrog vuam. Cov kav dej tso cua thiab kaw qhov yuav tsum tau txuas nrog flanges nrog sealing grooves, thiab lawv cov kev sib cuag yuav tsum du; flange gaskets yuav tsum yog tag nrho-lub voj voog tsis-interface roj hmab sealing rings.

3. Cov hlau phaj tuab ntawm cov kav dej cua thiab cov khoom siv hauv qhov project tseem ceeb yuav tsum ua kom tau raws li cov qauv tsim. Thaum tus qauv tsim tsis muaj cov cai tshwj xeeb. Lub thickness ntawm steel phaj yuav tsum siab tshaj 0.75mm.

4. Ib qho kawg ntawm engineering siab ntsuas cov yeeb nkab sab nraum lub qhov rooj tiv thaiv yuav tsum muab lub luj tshib downward; lwm qhov kawg yuav tsum tau nyob hauv chav cua lossis chav tswj, thiab lub pob valve yuav tsum tau nruab. Lub interface ntawm lub siab ntsuas lub raj dhau los ntawm kev tiv thaiv kab mob yuav tsum tau welded.

5. Kev ntsuas qhov ntawm lub qhov cua ntawm cov yeeb nkab thiab cov yeeb nkab decontamination yuav tsum tau ua tib lub sij hawm raws li cov yeeb nkab. Qhov ntsuas qhov thiab decontamination sampling tube yuav tsum tau thaiv.

6. Cov kev taw qhia ntawm huab cua ntws, valve qhib thiab kaw cov kev taw qhia thiab qhib degree nyob rau hauv lub qhov cua yeeb nkab yuav tsum tau qhia kom meej thiab meej.
