Dual Wall HDPE Pipe: Fidinnooyinka Sare ee Qaabka iyo Jiritaanka Sare

Safisaha dual wall hdpe ayaa muujiyaya awoodda saraynta leh oo kala duwan sababtoo ah shaqada korodhaynta korosha, kaas oo sameeyaya awoodda dharaska sare leh marka la socdo xaaladaha holjabaadsan ee lagu dhiso. Shaqada saraynta kala duwan kan uga wanaajiya saafisuhu dambalka tegeynta tegeynta berrin, ka hortaga ilbaxsan iyo ka hortaga in laga ilaaliyo awoodda hidroollijika badbaadinta jirka intii dheer, sida loo yaqaan daboolka da’doodka iyo daboolka barwaaqada. Korodhka korosha waxa caddaan kor u leh in kor u leh, sameeyaya geesiyada badan oo dambalka dib u soo saara, taas oo kordhinaya awoodda safisuhu in uu ilaaliyo kuwo ilbaxsan iyo uu ilaaliyo saafisuhu hoose qumman kahor joogto. Xisaabinta injineerka ayaa muujinaysa in safisaha dual wall hdpe ay suurta leedahay inay gargaarato dhammaan daboolka, gaar ahaan marro badan oo si kastaba ha ahaatee weyn kama ay isku daynayn inay khasallin tahay, waana raadinta sax ah ee lagu dhiso furiyada, meelaha heestaha iyo meelaha industriyaaliga sare. Khaaskada jiidka jiidka safisaha dual wall hdpe ayaa hubiya in awooddu wada rameysan yahay dhulka kala duwan, ka dib u laabnaa dhul dhididka gooniiska ilaa dhulka qumman ee argagax. Tijaabada awoodda saraynta badbaadinta waxa muujinaysa in safisaha dual wall hdpe ay sii socotaa awoodda dharaska marro badan, hubinaya inay noqon kartaa mid aad u fiican ee habaynta badbaadinta.

Xaqiiqda kimiyaaf ah ee buuxa ee dhulka labaadka hdpe ayaa siisayga la'aan ka ilaalinta aad u qalbiga badan oo leh jiljilada xadiddu, kuwaas oo kale habdhaladda iyo sabaqlaha. Lavaanta polyethylene ee heer sare ayaa muujinaya inay tahay jiljilkiin kala duwan ee asiduhu, kaynuunka, maleelaha, iyo sulwaadda orgaanik, taasoo hubinaya inay noqon kartaa dherer si dheer marka loo eego hawadaha kimaayiyeed kala duwan, halkaas oo dhulalka kale waxay baabbi'in doonaan si gaaban. Sidaas daraaddeed ma lagama filna in lagusoodo isku-dharka qiimaha sare, nidaamka ilaaliynta cathodic, ama dib-u-sarreeyinka awoodga ah oo ku daraysa qiimaha weyn ee gudaha dhulalka guud. Dhulka labaadka hdpe wuxuu haysta xaqiiqihii shaqsiyadeed iyo sayniska marka loo eego madooyinka sabaqle, kiimikada agroobaatar, iyo jiljilka dhexdhexaadka biyaha dhaxalka ah oo kale waxay laabbaan kartaa inay dhashoon korrosion ama deggen inay laabbaan kartaa jiljilka xadidka ama cementitious. Tijaabiyaal laboratoor ayaa muujinaya in dhulka labaadka hdpe uu haysto xaqiiqihii shaqsiyadeed ka dib marka loo eego foomaha kimaayiyeed kasaneen, taasoo rabbita inay adag yihiin sabaqlaha sabaqle, bidaacmada kiimikada, iyo shaqooyinka agroobaatar. Xaqiiqidda jiljilka ku saabsan dabeecadaha jiyogta ayaa ilaalinaya in baktaareyashu iyo fungi ay dhasho, taasoo waxay keeni kartaa in dhulalka kale ay jebdiyaan iyo in biyaha lagu dhasheyso. Sidaas daraaddeed ma jiro goobta korrosion oo ku saabsan mikroobaatar, sidoo kalena in la ilaaliyo in jiljilka laga qalbiyo dhibaatada dabeecadaha jiyogta. Durabilityxii aysankeed ayaa sii socda ilaa UV resistance marka dhulalka ay ku tiilmaan shuqulta iyo lagu dhiso, ilaa in la ilaaliyo deggenkii lavaantahooda oo kale ay keeni kartaa inay jebidiyaan si dheer. Xaqiiqidda jiljilka ku saabsan jiljilka hdpe ayaa oggolaanayaa inay haystaan xaqiiqihii kimaayiyeed kala duwan ee tixgeliyaha, taasoo hubinaya inay noqon kartaa mid walba marka loo eego hawa iyo shaqooyinka kala duwan. Tijaabiyaal electrochemical ayaa rabbita in dhulka labaadka hdpe ma tahay galvanic corrosion marka loo isticmaalayo dhulalka xadidka ama dhulalka kale, taasoo faa'iido u leh in lagu sameeyo nidaamka, sidoo kale ma lagama filna in lagu istcmaalaa joints insulation ama anodes sacrificial. Xaqiiqidda kimiaha ee lavaanta ayaa hubinaya inay ma leexsan kartaa shey qalbiga ah biyaha la dhashay, taasoo rabbita inay noqon kartaa mid la'aan habdhaliyaha biyaha la dhanka, sidoo kale aysankeedka aysankeed ee biyaha la dhanka.

Fa’iidooyinka iqtisadiya ee duulaha warshada hdpe ay ka sii dartaa qiimaha bilowga ah ee alaabta, waxayna siinaysaa in la kala qorsheyno si weyn marka laga soo wado dhammaan dhaqangelinta mashruucadda ilaa inta badan ee sheegga awoodsiga. Qalabka yar bixidhka duulaha warshada hdpe ay leedahay sabab u leh in qiimaha guuridda lagu gudbiyey ay keento si weyn, maxaa yeelay, toosan tiro ka badan loo guuridi karaa per truck load loo eego alaabta kale oo loo yaqaan concrete ama steel, taasoo ku xad laabanaya qiimaha guuridda iyo helitaanka alaabta ku jira goobta shaqada. Helitaanka shaqada ay socda si fiican sababtoo ah qalabka yar bixidhka qaybooda kala duwan ee duulaha, waxayna ogolaada in kooxaha yar dhagaysato toosan dheer, taasoo ku xad laabanaya qiimaha shaqada halka ay ku hortagaya nabadgelyada shaqshaqeeyaha. Hore u lehna in la helo toosan dheer, imisa qayboodna loo baahan yahay marka loo eego istaalka caadiga ah, taasoo ku xad laabanaya qiimaha alaabta ee isku definteeda iyo waqtiga shaqada loo eego sameynta isku definteeda, halka ay ka xad laabaanaya sidoo kale noocyada loo yaqaan leak points (goobaha loo yaqaan in ay daaqdaan) oo loo yaqaan in ay barbardhigto maalin kulan. Wuxuu si joogto ah u kala qorsaneyn karaa doorka diggada sababtoo ah in duuluhu uu leeyahay ammaan in uu hubbo qaadasho yar ama in uu kala soo saar lahaado marka loo dugaa, taasoo ogolaada in la helo beddellada yar oo laga yaqaan bedding requirements iyo shaqooyinka diggada ay socda si degdeg ah. Duuluhu warshada hdpe waxaa lagu dul wadaan isticmaalka teknoolojiyada aan diggada u baahan tahay oo loo yaqaan horizontal directional drilling iyo pipe bursting, taasoo iskudilnaa in la baahan yahay in la digo si weyn magaalooyinkha, waxaana kala xad laabanaya qiimaha la xidhiidha khaladka dhaawacyada, beddelida adeegyada iyo dib u celinta dhulka. Qiimaha sanadkii dheer ee maareynta ay sii wadnayn midab ah sababtoo ah in duuluhu uu leeyahay ammaan in uu kala soo saar lahaado korrosion, scaling, iyo horumarinta hayotanka, taasoo iskudilnaa in la baahan yahay in la gacan geliyo, la reline, ama la beddelo si toddoba toddoba, oo ay leedahay alaabta duulaha caadiga ah. Qiimaha awoodsiga ee pumping operations ay sii wadnayn yar marka laga soo wado kallamada dhaqangelinta duuluhu sababtoo ah in dhulka gudaha waa smooth (raax leh) oo uu ilaaliyaa fikradaha hydraulics iyo in uu kala soo saar lahaado roughening (dhulka raax leh) oo ay dhacdo alaabta kale ee duulaha muddo dheer. Dukarrada duulaha warshada hdpe ay kala xad laabaanaya habaabka in ay daaqdaan sababtoo ah in dhulka lagu wareejinayo ama dhacdada ardaynta, taasoo ku xad laabanaya qiimaha maareynta jajabka iyo khaladka awoodsiga oo kale oo leedahay in ay abuurtaan kharash weyn kala duwan magaalooyinka iyo abaadiyada sayniska. Mashruucadda horumarinta iyo beddelinta habaabka ay faa’iideysamaan fikradaha fudud ee ku darista duulaha hdpe cusub ee kala duwan ku jira habaabka hore isticmaalaya qiimaha isku definteeda caadiga ah, taasoo ku xad laabanaya qiimaha maareynta iyo xooggadeedka shaqada marka loo eego horumarinta infrastructuurta.
