Thaum txhim kho pp yeeb nkab, peb yuav tsum xub txiav txim siab seb qhov kub thiab txias puas yuav cuam tshuam rau kev teeb tsa zoo. Yog tias qhov kub siab tshaj 40 degree lossis qis dua 0 degree, nws tsis haum rau kev teeb tsa. Peb yuav tsum xaiv lub sijhawm uas qhov kub thiab txias haum rau kev teeb tsa. Vim tias qhov nthuav dav coefficient ntawm pp yeeb nkab yog qhov loj, thermal them nyiaj yuav tsum tau txiav txim siab thaum lub sijhawm teeb tsa, uas feem ntau yog raws li kev them nyiaj ntuj, xws li kev siv cov square expansion pob qij txha. Thaum cov yeeb nkab PP muab tso rau saum taub hau, cov yeeb nkab yuav tsum tau txais kev txhawb nqa los ntawm cov yeeb nkab txhawb nqa, thiab cov yeeb nkab txhawb nqa tuaj yeem ua los ntawm lub kaum sab xis steel, ib nrab-section steel yeeb nkab thiab lwm yam ntaub ntawv, kom cov polypropylene muaj zog tuaj yeem ncav cuag lub yeeb nkab. kev txhawb nqa. Cov kua dej nyob rau hauv tib pem teb tau optimized nyob rau hauv ib txwm siv technology. Cov kev ua haujlwm sab nraud ntawm caisson yog hloov los ntawm cov khoom ntim dej ua ntej (nrog nws tus kheej cov qhov dej ntws thib ob). Cov dej ntim hauv caisson ntws ncaj qha mus rau hauv lub raj zoo. Los ntawm lub qhov dej ntawm PVC pre-embedded dej accumulator nyob rau hauv lub raj zoo, nws yog tawm mus rau lub riser, uas tsis yuav tsum tau rau nruab ib sab ntws, tab sis kuj xyuas kom meej lub smoothness ntawm cov kua. Thaum PP yeeb nkab yuav tsum tau muab zais. Nws raug nquahu kom siv cov yeeb nkab trench rau tso. Cov kav dej feem ntau yog welded thiab txuas nrog. Yog tias lawv yuav tsum tau muab faus rau cov laj thawj tshwj xeeb, lawv yuav tsum tau muab faus ncaj qha rau hauv daim ntawv ntawm lub casing kom tsis txhob muaj cov khib nyiab nyuaj sib xyaw hauv cov khoom siv rov qab thiab cov kav dej yuav puas. Thaum cov yeeb nkab PP flanged, nws yuav tsum nruj me ntsis hauv nruab nrab, thiab qhov siab tshaj plaws tso cai sib txawv ntawm axial kev taw qhia tsis ntau tshaj 2 hli. Nws yuav tsum tsis txhob raug kho los ntawm kev yuam kom nruj cov bolts. Cov bolts tau nruj ob zaug, thiab thawj zaug yog sib xws thiab symmetrical raws li kab pheeb ces kaum dua, thiab tom qab ntawd zawm cov bolts.
