Kev ceev faj yuav tsum tau them rau daim ntawv thov ntawm PPR pipeline, xws li kev teeb tsa ntawm cov kav dej sib txawv raws li daim ntawv thov ib puag ncig thiab qhov chaw qhov tob ntawm faus PPR pipeline; Kev teeb tsa cov kav dej hauv qab kev txav chaw; Kev sib xyaw ntawm cov kav dej hauv tsev; Configuration ntawm cov yeeb nkab hauv tsev, thiab lwm yam.
1, Qhov tob qhov chaw ntawm faus PPR pipeline
1. Cov yeeb nkab steel lossis cam khwb cia hlau PPR yeeb nkab rau dej yuav tsum tau muab tso rau hauv txoj kev tsheb ciav hlau, thiab qhov tob ntawm cov yeeb nkab loj yuav tsum tsis pub tsawg dua 1.5m los ntawm hauv qab mus rau saum cov yeeb nkab.
2. Thaum lub raj xa dej muaj kev ntsuas los tiv thaiv kev puas tsuaj los yog tsis tuaj yeem ua rau cov tshuab puas. Qhov tob faus tuaj yeem tsawg dua li tus qauv 1.25m.
2, Kev sib txuas ntawm cov kav dej hauv tsev PPR yuav tsum ua raws li cov cai hauv qab no.
1. Cov kav dej yuav tsum tsis txhob raug offset ntawm lub axis. Thaum txwv los ntawm cov xwm txheej, nws yuav tsum tau txuas nrog B- zoo li cov yeeb nkab lossis ob lub luj tshib 45.
2. Thaum cov ceg yeeb nkab thiab riser txuas nrog rau kab rov tav lub ntsiab yeeb nkab, lawv yuav tsum tau txuas nrog hauv 45 degrees los ntawm sab saum toj lossis ob sab ntawm cov yeeb nkab loj.
3. Nws tsis pom zoo kom txuas lub luj tshib nrog txoj kab uas hla ntawm 45 degrees los yog ob txoj hlua khi nrog lub vojvoog ntawm 90 degrees ntawm lub luj tshib thiab riser.
4. Cov twj tso kua dej PPR yeeb nkab yog vertically txuas nrog kab rov tav cov yeeb nkab, thiab 90 degree inclined tee PPR yeeb nkab haum ntawm PPR yeeb nkab yuav tsum tau saws.
5. Rau kev sib txuas ntawm cov yeeb nkab kab rov tav thiab ntsug cov yeeb nkab ntawm PPR raj, 45 degree inclined tee lossis 45 degree inclined cross thiab PPR yeeb nkab fittings raws cov dej, roj lossis dej hla yuav tsum tau saws.
