1. Marka la eego xaalada aan saameyn ku yeelan alxanka sanka, dhererka kaydsan ee budada epoxy ee dhamaadka lakabka polyetylen waa in si habboon loo kordhiyaa si looga hortago 3PE ka-hortagga ka-hortagga daxalka ee ay keento waqtiga dheer ee isugeyntaDhuumaha birtaiyo daxalka halista ah ee birta ee dhamaadka tuubada.

2. Marka tuubooyinka lidka ku ah ay ku jiraan hawada furan muddo dheer, waa in lagu daboolaa cidhifyada tuubooyinka si looga hortago in biyaha roobka ay daxaloobaan oo ay u keenaan daxal halis ah cidhifyada tuubooyinka.

3. Haddii muddada dhismaha dhuumaha ay dheer tahay, rinjiga ka hortagga miridhku weldable waxaa lagu rinjiyeeyaa birta qaawan ee dhamaadka tuubada si looga hortago lakabka 3PE ee ka hortagga daxalka ka soo baxa sababtoo ah daxalka inta lagu jiro kaydinta.

4. Si adag u xakamee tayada shiidida ee tolida alxanka ee lagu hayo dhamaadka tuubada.Dusha sare ee jeexdin polyetylenka ee alxanka ayaa la mid ah qaybaha kale ee jidhka biibiile.Ka dhig budada epoxy in ka badan 20mm si aad uga hortagto in gunta budada epoxy-ga ee alxanka ay marka hore daxaloobaan oo ay keento lakabka 3PE ee ka hortagga daxalka.

Waa in fiiro gaar ah loo yeesho shiidida alxanka dhamaadka tuubada:

1) Laga bilaabo bilawga tolitaanka alxanka ee jeexjeexyada polyetylen, waa in ay ahaataa qayb siman oo ka mid ah lakabka polyetylen ee 10-20mm oo aan lahayn dhererka alxanka xad-dhaafka ah iyo la mid ah jidhka biibiile si loo hubiyo soo-saarka iyo isku-xidhka polyetylen jeexdin at tayada dhamaadka tuubada.

2) Xoojinta tolida alxanka ka dib marka la shiido waa in ay ahaataa sida ugu macquulsan ee jidhka biibiile, waana in aanay jirin xoojin cad oo ka hortagaysa in budada epoxy-ka la nadiifiyo marka la shiidiyo chamfer ee lakabka polyetylen.

3) Qalabka dusha sare ee alxanka iyo qaybta kala-guurka ee meesha la dayactiray waa inay la mid noqdaan lakabka lakabka polyetylen (≤30°) si ay xoogga tuujin ee rullaluistemadka tuujin uu si siman u cadaadi karo lakabka polyetylenka Si looga hortago lakabka polyetylenka inuu duuduubo sababtoo ah ku dhejinta liidata lakabka ka-hortagga daxalka ee jeexdin.

5. Dahaarka budada epoxy ee qaybta loo qoondeeyay waxay dib u dhigi kartaa cirifka cirifka ee uu keeno daxalka kaliya marka ilaalintu dhammaato.Habaynta birta ee birta ah ee birta ah ee tuubbada ka shaqaynaysa waxa lagu shiido giraangiraha birta, taas oo dhaawici doonta daahan budada epoxy.Bevel waa in la makiinado halkii, iyo lakabka hoose ee mindi-cidhif waa in la xaddido by qalab si loo xakameeyo qoto dheer goynta ee qalabka, si aanay u dhaawacmin daahan budada epoxy.
