Ngaba ujongene nokuvuza okanye ubuthathaka kwinkqubo yakho yokuhambisa imibhobho? Ukusebenzisa ukufakwa okungafanelekanga kwemibhobho ye-HDPE yimbangela eqhelekileyo yokusilela kweenkqubo ezibizayo kunye nokulibaziseka kweprojekthi.

Iipayipi ze-HDPE ziqhagamshelwe kusetyenziswa iintlobo ezintathu eziphambili zezixhobo zokufakelwa:ukuhlanganiswa kweempundu, ukudibana kwe-electrofusion, kunye nezixhobo zokucinezela ngoomatshini. Iindlela zokudibanisa zenza ijoyinti esisigxina, eyomeleleyo njengepayipi ngokwayo, ngelixa izixhobo zokucinezela zibonelela ngesitywina esisuswayo nesinoomatshini.

Ukwazi amagama ezixhobo zokufakela izinto sisiqalo nje. Umphathi wokuthenga okwinqanaba eliphezulu njengoCarlos uyaqonda ukuba ubuchule bokwenyani buxhomekeke ekwazini ukuba zeziphi izixhobo zokufakela izinto oza kuzisebenzisela imeko ethile. Olu lwazi lulo olukhusela utyalo-mali lwakho, luqinisekisa ukuthembeka kweprojekthi, kwaye lwakha udumo lokuthembeka.

Uzidibanisa njani iipayipi zeHDPE?

Ngaba unengxaki yokudibanisa imibhobho enzima okanye engathembekanga? Ijoyinti engalunganga yeyona khonkco ibuthathaka kuyo nayiphi na inkqubo yemibhobho, elinde ukubangela iingxaki ekuhambeni kwexesha.

Uqhagamshela imibhobho ye-HDPE ngokuwelda ubushushu (i-butt fusion okanye i-electrofusion) ukuze kubekho ibhondi ehlala ihleli, engavuziyo, okanye ngee-mechanical compression fittings zeedayamitha ezincinci okanye uqhagamshelo lwexeshana apho kungekho zixhobo zikhethekileyo zifunekayo. Indlela nganye isebenza injongo eyahlukileyo.

Ngokusuka kumava am ePntek, ndizibonele ngokwam indlela ukukhetha indlela yoqhagamshelo efanelekileyo yokonga ixesha elininzi kunye nemali kwindawo. Xa uCarlos enceda umakhi ukuba akhethe phakathi kokufakela ucinezelo olulula lokulungisa okuncinci kunye nokudibanisa i-butt yombhobho omkhulu, akathengisi nje inxalenye; uthengisa isisombululo esiqinisekisa impumelelo yexesha elide.

Ukuhlanganiswa Kweempundu

Le yeyona ndlela ixhaphakileyo kwimibhobho yeHDPE enobukhulu obukhulu. Le nkqubo ilula. Umatshini okhethekileyo ubamba iziphelo ezimbini zemibhobho zilungelelene ngokugqibeleleyo. Ipleyiti yeheater ibekwa phakathi kwazo, inyibilikisa iziphelo ukuya kubushushu obuthile. Ipleyiti iyasuswa, kwaye iziphelo ezinyibilikisiweyo zicinezelwe kunye phantsi koxinzelelo olulawulwayo. Ziyaphola ukuze zenze iqhekeza elinye, eliqhubekayo lombhobho. Eli khonkco alivuzi ngokupheleleyo kwaye liqinile njengombhobho wokuqala.

Ukudibanisa nge-Electro

Le ndlela ifanelekile xa kulungiswa okanye kwiindawo ezixineneyo apho umatshini wokudibanisa ii-butt ungangeni khona. Izixhobo zokudibanisa ii-electrofusion zine-coil yocingo efakwe ngaphakathi kuzo. Iziphelo zepayipi zifakwa kwindawo yokudibanisa, kwaye iprosesa yokudibanisa ii-electrofusion ithumela umbane kwiintambo. Ubushushu obuvela kwiintambo bunyibilikisa ingaphakathi le-fitting kunye nengaphandle lombhobho, buzidibanisa zibe yi-joint eqinileyo neyomeleleyo.

Izixhobo zoxinzelelo lweMechanical

Kwiidayamitha ezincinci (ngesiqhelo ezingaphantsi kwe-intshi ezi-4 okanye i-110mm), izixhobo zokucinezela zisisombululo esilungileyo nesilula. Azidingi zixhobo zikhethekileyo. Utshixa nje i-nut kunye neringi yokubamba phezu kombhobho, ufake umbhobho emzimbeni wokufakela, kwaye uqinise i-nut. Oku kucinezela i-O-ring ukwenza isitywino esingangeni manzi. Kuyakhawuleza, kulula, kwaye kungenziwa nangubani na osebenza.

Ngaba i-HDPE ingcono kune-PVC?

Ngaba uxoxa ngeHDPE kunye nePVC kwiprojekthi yakho elandelayo? Ukukhetha izinto ezingafanelekanga kunokukhokelela kwiintloko ezibuhlungu zokufakelwa kunye nenkqubo engafezekisi ulindelo lokusebenza.

Akukho nanye kwezi 'zingcono' kwihlabathi liphela. I-HDPE ingcono ngenxa yokuguquguquka kwayo, ukumelana neekhemikhali, kunye nokuqina kokunyibilika komkhenkce, okwenza ukuba ilungele ukufakwa ngaphandle kwemijelo kunye neemeko ezinzima. I-PVC ingcono ngenxa yokuqina kwayo, amandla aphezulu okutsalwa, kunye nexabiso eliphantsi, okwenza ukuba ibe lolona khetho luphezulu kwiindlela zamanzi kunye nokusetyenziswa koxinzelelo.

Njengenkokeli yePntek, inkampani egqwesileyo kwi-PVC, ndibone iiprojekthi ezininzi apho i-PVC inika ulungelelwaniso olugqibeleleyo lokusebenza kunye nexabiso. Nangona kunjalo, ndingowokuqala ukuvuma ukuba i-HDPE sisixhobo esifanelekileyo somsebenzi. Ingcali efana noCarlos iyazi ukuba eyona ndlela ilungileyo yokukhonza abathengi bayo kukubakhokela kwizinto ezifanelekileyo kwiimfuno zabo ezithile, kungekhona nje ukutyhala imveliso enye ngaphezu kwenye.

Ukuguquguquka vs. Ukuqina

Umahluko ocacileyo kukuba bhetyebhetye. Ukukwazi kwe-HDPE ukugoba kuyivumela ukuba ifakwe kwiikona ngaphandle kwezinto ezongezelelweyo kwaye kuyenza ifaneleke kakhulu ekufakelweni ngaphandle kwemisele (ukuyitsala emhlabeni). I-PVC iqinile kakhulu, nto leyo eyinika amandla aphezulu okubeka umqadi wokungcwaba kwaye ithintela ukugoba xa ibaleka ixesha elide, lithe tye.

Indlela yokujoyina kunye neendleko

Le yinto ebalulekileyo kuCarlos nakubathengi bakhe. I-PVC idityaniswe neeprimer ezilula nezingabizi kakhulu kunye nesamente ye-solvent, okanye nee-bell ends ezine-gasket. Izixhobo zilula kwaye umsebenzi uyakhawuleza. I-HDPE ifuna izixhobo zokuxuba ubushushu ezibizayo nezikhethekileyo kunye nabaqhubi abaqinisekisiweyo, nto leyo eyandisa iindleko zeprojekthi yokuqala kunye nobunzima. Ngokuphathelele iindleko zezinto, i-PVC ngokubanzi ibiza kancinci kune-HDPE kudidi olufanayo loxinzelelo.

Ngaba i-HDPE ilinganiswa kwi-OD okanye kwi-ID?

Ngaba uku-odola umbhobho ongalunganga kungaphazamisa yonke ishedyuli yakho yeprojekthi? Ukungaqondi kakuhle indlela umbhobho we-HDPE olinganiswa ngayo kunokukhokelela kwiipayipi kunye nezixhobo ezingahambelaniyo, kuchithe ixesha kunye nemali.

Ubukhulu bepayipi ye-HDPE busekelwe kwiDayamitha yangaphandle elawulwayo (OD). Oku kubalulekile kuba iindlela zokudibanisa i-fusion zifuna umphezulu wangaphandle wepayipi kunye nokufakelwa ukuze kuhambelane ngokuchanekileyo ne-weld ephumelelayo.

Le yinkcukacha yobuchwephesha eyahlula aba bangengabo abanamava kwiingcali. Xa ndithetha nomphathi wokuthenga onjengoCarlos aze achaze umbhobho nge-OD kunye ne-SDR yawo, ndiyazi ukuba ndisebenzisana nengcali. Uyaqonda ukuba olu lwazi alulo nje inani elikwiphepha leenkcazo; sisiseko senkqubo ethembekileyo, engenamanzi. Ububanzi bangaphakathi (ID) buya kutshintsha ngokuxhomekeke kubukhulu bodonga, kodwa i-OD ihlala ifana kubungakanani bombhobho obunikiweyo.

Kutheni i-Diameter yangaphandle ibalulekile

Ukuxubana kobushushu kusebenza ngokunyibilikisa umphezulu wangaphandle wombhobho kunye nomphezulu wangaphakathi wombhobho (okanye umphezulu wangaphandle womnye umbhobho). Ukuze oku kusebenze, umphezulu kufuneka ulungelelane ngokugqibeleleyo. Ngokugcina i-OD ingaguquki, abavelisi baqinisekisa ukuba nawuphi na umbhobho wobukhulu obuthile uya kuhambelana nayo nayiphi na i-fitting okanye umatshini wokudibanisa ohambelanayo, nokuba ingakanani na i-pressure rating yayo.

Ukuqonda i-SDR (uMlinganiselo oMgangatho oMiselweyo)

• Yintoni:I-SDR ngumlinganiselo wobubanzi bangaphandle bombhobho nobukhulu bodonga lwawo.
• Ifomula:I-SDR = OD / Ubukhulu bodonga
• Ithetha ukuthini: A ezantsiInombolo ye-SDR ithetha i-tyebileudonga lombhobho. Udonga olutyebileyo lunokumelana noxinzelelo oluphezulu. Umzekelo, umbhobho we-SDR 11 unodonga olutyebileyo kunye nomlinganiselo woxinzelelo oluphezulu kunembhobho we-SDR 17 wobukhulu obufanayo. UCarlos kufuneka azi zombini i-OD efunekayo kunye ne-SDR ukuze aodole umbhobho ochanekileyo ngokweemfuno zoxinzelelo zabathengi bakhe.

Loluphi uhlobo lwejoyinti olusetyenziswa kwipayipi yeHDPE?

Ngaba ujonge i-pipe joint onokuyigquma uze uyilibale? Uloyiko lokuvuza kwixesha elizayo okuvela kwi-inshorensi luyinkxalabo enkulu kubakhi kunye nabanini beenkqubo.

Ijoyinti ephambili neyomeleleyo esetyenziselwa umbhobho we-HDPE yijoyinti ye-butt fusion. Le nkqubo yokuwelda ngobushushu idala uqhagamshelo olungenamthungo (olungenamthungo) olungenako ukuvuza ngokupheleleyo kwaye luhlala luqinile kunombhobho ngokwawo.

Ingcamango yenkqubo "efanayo" itshintsha umdlalo. Oku kuthetha ukuba udala iqhekeza elinye elide, eliqhubekayo lombhobho elingenazo iintambo zombane ezinokukhululeka okanye zonakale ngokuhamba kwexesha. Kumthengi onjengoCarlos, ukukwazi ukubonelela ngenkqubo esusa umngcipheko wokungasebenzi kakuhle kwamalungu yinzuzo enkulu yokhuphiswano. Lithemba lokugqibela lokuthembeka kwexesha elide.

Ukudala Inkqubo Engavuziyo Ngenene

Ijoyinti edityaniswe ngeempundu ayifani noqhagamshelo olunamathelisiweyo okanye olunamathelisiweyo; kukuphinda kwenziwe izinto ngokwazo. Iitsheyini zepolymer ezivela kwiziphelo zombini zemibhobho ziyaxubana zikwimeko yazo enyibilikisiweyo kwaye zipholile ukuze zenze into enye eqinileyo. I-bead encinci eyenzeka ngaphakathi nangaphandle kombhobho yimbonakaliso ebonakalayo ye-weld ephumeleleyo. Le joyinti idityaniswe kangangokuba igcina ukuguquguquka kunye namandla ombhobho ngokugqibeleleyo.

Kutheni le nto inguMgangatho weGolide

Olu hlobo lwejoyinti luthembeke kakhulu kangangokuba luyindlela efanelekileyo yokusetyenziswa njengemigca yokusasazwa kwegesi yendalo, iipayipi zamanzi ezinoxinzelelo oluphezulu, kunye nokuthuthwa kweekhemikhali kwimizi-mveliso. Ijoyinti iyazibamba ngokupheleleyo, oko kuthetha ukuba ayinakuqhekeka phantsi koxinzelelo okanye intshukumo yomhlaba. Oku kususa isidingo seebhloko zokutyhala ezibizayo okanye izithintelo ezifunekayo kwezinye iinkqubo ezininzi zemibhobho, nto leyo enciphisa ngakumbi iindleko zokufakela kunye nobunzima.

Isiphelo

Iinkqubo ze-HDPE zixhomekeke kwi-fusion okanyeizixhobo zokucinezelaUkudibanisa iibutt kudala i-joint eqinileyo nengavuziyo. Ukukhetha phakathi kwe-HDPE eguquguqukayo kunye ne-PVC eqinileyo nengabizi kakhulu kuxhomekeke ngokupheleleyo kwiimfuno ezithile zeprojekthi.
