1. Cov tsos ntawm cov kav hlau tsis xeb hlau nkag mus thiab tawm hauv lub tsev yuav tsum tau soj ntsuam raws li hauv qab no:
① Tshawb xyuas txhua lub hauv paus kom paub meej tias cov txheej txheem polyethylene yog tiaj tus thiab du, tsis muaj npuas tsaus, pitting, wrinkles, lossis tawg. Tag nrho cov xim yuav tsum yog uniform. Yuav tsum tsis txhob muaj corrosion ntau dhau ntawm cov yeeb nkab.
② Qhov curvature ntawm cov yeeb nkab steel yuav tsum yog <0.2% ntawm qhov ntev ntawm cov yeeb nkab steel, thiab nws cov ovality yuav tsum yog ≤0.2% ntawm sab nraud ntawm cov yeeb nkab steel. Qhov saum npoo ntawm tag nrho cov yeeb nkab muaj qhov tsis sib xws hauv zos <2 hli.

2. Cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau thaum thauj cov kav dej los tiv thaiv corrosion:
① Chaw thau khoom thiab tshem tawm: Siv lub hoist uas tsis ua rau lub qhov ncauj puas thiab tsis ua rau cov txheej txheem tiv thaiv corrosion. Tag nrho cov cuab yeej tsim kho thiab cov cuab yeej siv yuav tsum ua raws li cov cai thaum thauj khoom thiab tshem tawm. Ua ntej thauj khoom, qib tiv thaiv corrosion, cov khoom siv, thiab phab ntsa tuab ntawm cov kav dej yuav tsum tau kuaj ua ntej, thiab kev sib xyaw ua ke tsis raug pom zoo.
② Kev Thauj Mus Los: Lub thrust baffle yuav tsum tau ntsia nruab nrab ntawm lub trailer thiab lub cab. Thaum thauj cov kav dej los tiv thaiv corrosion, lawv yuav tsum tau khi kom ruaj khov thiab kev ntsuas los tiv thaiv cov txheej txheem tiv thaiv corrosion yuav tsum tau ua kom sai. Cov ntawv roj hmab lossis qee cov ntaub ntawv mos yuav tsum tau nruab nruab nrab ntawm cov kav dej los tiv thaiv corrosion thiab cov thav duab lossis kab, thiab nruab nrab ntawm cov kav dej los tiv thaiv corrosion.

3. Cov qauv kev cia khoom yog dab tsi:
① Cov kav dej, cov yeeb nkab fittings, thiab li qub yuav tsum tau muab khaws cia kom zoo raws li cov lus qhia. Ua tib zoo saib xyuas thaum khaws cia kom tsis txhob xeb, deformation, thiab kev laus.
② Kuj tseem muaj cov ntaub ntawv xws li iav ntaub, cov ntaub qhwv lub tshav kub, thiab lub tes tsho uas muaj cua sov uas yuav tsum tau muab khaws cia rau hauv qhov chaw qhuav thiab qhov cua zoo.
③ Cov kav dej, cov yeeb nkab fittings, li qub, thiab lwm yam ntaub ntawv tuaj yeem raug cais tawm thiab khaws cia hauv huab cua qhib. Ntawm chav kawm, qhov chaw cia khoom xaiv yuav tsum tiaj tus thiab tsis muaj pob zeb, thiab yuav tsum tsis txhob muaj dej ntau hauv av. Txoj kev nqes hav tau lees tias yog 1% mus rau 2%, thiab muaj cov kwj deg.
④ Cov kav dej tiv thaiv corrosion hauv lub tsev yuav tsum tau muab tso rau hauv cov khaubncaws sab nraud povtseg, thiab qhov siab xav tau los xyuas kom meej tias cov kav dej tsis poob lawv cov duab. Muab lawv cais raws li qhov sib txawv specifications thiab cov ntaub ntawv. Cov cushions mos yuav tsum tau muab tso rau ntawm txhua txheej ntawm cov kav dej los tiv thaiv corrosion, thiab ob kab pw tsaug zog yuav tsum tau muab tso rau hauv qab cov kav dej. Qhov kev ncua deb ntawm cov kav dej yuav tsum yog> 50mm los ntawm hauv av.
⑤ Yog tias nws yog kev tsim kho ntawm qhov chaw, muaj qee qhov yuav tsum tau khaws cia rau cov kav dej: ob qhov kev txhawb nqa yuav tsum tau siv rau hauv qab, qhov kev ncua deb ntawm lawv yog li 4m txog 8m, cov yeeb nkab los tiv thaiv corrosion yuav tsum tsis pub tsawg dua 100mm los ntawm hauv av, cov ntaub ntawv txhawb nqa thiab cov kav dej los tiv thaiv cov kav dej thiab cov kav dej los tiv thaiv corrosion yuav tsum tau padded nrog hloov tau yooj yim spacers.
