Uzama ukufumana iipayipi uze ubone ukuba zisetyenziswe “kwii-poly pipe” kunye “ne-HDPE pipe” kwiingcaphuno nakwii-datasheets. Oku kudala ukungaqiniseki, okukwenza ukhathazeke ukuba uthelekisa iimveliso ezifanelekileyo okanye uphoswa ziinkcukacha ezibalulekileyo.

Akukho mahluko ekusebenzeni. Igama elithi “Poly pipe” ligama eliqhelekileyo nelingekho sesikweni elisetyenziswa kwishishini le-HDPE (High-Density Polyethylene). Xa umntu okwishishini lemisebenzi yamanzi esithi “poly pipe,” uthetha nge-HDPE pipe esetyenziselwa ukusetyenziswa koxinzelelo olufana namanzi kunye neepayipi zegesi.

Bendikwi-video call nomsasazi omtsha eSurabaya, kwaye wayesoloko ebuza ngamaxabiso ethu “e-poly pipe” xa ethelekiswa namaxabiso ethu “e-HDPE”. Ndayimisa incoko ndaza ndachaza ukuba ziyafana. Ubuso bakhe babonisa ukukhululeka kwangoko. Wayecinga ukuba uphoswa yinto yobugcisa. Eli linqaku eliqhelekileyo lokudideka. Igama elithi “Poly” ligama nje elilula ukulithetha, ngelixa elithi “HDPE” ligama lobunjineli elithile. Cinga ngalo ngolu hlobo: ungacela “iCoke,” kodwa imveliso ngokwayo yiCoca-Cola. Ngayo nayiphi na injongo yobungcali, sithetha ngeHDPE, kwaye ngesiqhelo sibanga lePE100.

Ngaba ungayisebenzisa i-PVC fittings kwipayipi ye-HDPE?

Unenqwaba yezinto ezifakelwa kwi-PVC kunye nombhobho we-HDPE ofuna uqhagamshelo. Ukusebenzisa oko unako kuya kuba lula kwaye kungabizi kakhulu, kodwa ngaba kukhuselekile okanye kunokwenzeka?

Hayi, awunakusebenzisa izixhobo zePVC eziqhelekileyo kumbhobho weHDPE. Ezi zinto azihambelani ngokweekhemikhali kwaye zifuna iindlela ezahlukeneyo zokudibanisa. Ukuzama ukuncamathisela isixhobo sePVC kumbhobho weHDPE kuya kudala ijoyinti eqinisekisiweyo ukuba ayisebenzi phantsi koxinzelelo.

Le yingxaki ebalulekileyo yokhuseleko nokuthembeka. I-PVC kunye ne-HDPE ziintsapho ezimbini ezahlukeneyo zeplastiki. Izixhobo ze-PVC zidityaniswe kusetyenziswa isamente ye-solvent, uhlobo lweglue yekhemikhali. I-solvent isebenza ngokuthambisa umphezulu wombhobho we-PVC ngeekhemikhali kunye nokudibanisa, okuzivumela ukuba zidityaniswe njengoko i-solvent iphela. I-HDPE, kwelinye icala, yi-polyolefin. Inomphezulu onjenge-wax, ongenamanzi apho iglu okanye isamente ye-solvent inokudibana khona ngokufanelekileyo. Ukuba uzama ukuyincamathisela, ubuya kudala isitywino esibuthathaka, sexeshana esiza kuqhekeka ngokukhawuleza nje ukuba umgca ucinezelwe. Eyona ndlela ichanekileyo yokuqhagamshela inkqubo ye-PVC kwinkqubo ye-HDPE kukusebenzisa i-transition fitting ekhethekileyo, efana ne-iadaptha yeflangekwicala ngalinye lidityaniswe ngebholiti, okanye ikhonkco elithile lokucinezela elenzelwe ukuhlanganisa izinto ezimbini ezahlukeneyo.

Ngaba uyayincamathisela ipayipi yeHDPE?

Kufuneka udibanise iziqwenga ezibini zombhobho we-HDPE. Nge-PVC, inkqubo ilula: sebenzisa i-primer kunye neglu. Oku kukukhokelela ekubeni uzibuze ukuba ingaba kukho iglu efanayo na kumbhobho we-HDPE.

Hayi, awuze usebenzise iglu kumbhobho we-HDPE. Indlela eyenziwe ngayo i-HDPE ngokwekhemikhali yenza kube nzima ukuba iglu idale iqhina elihlala lihleli, eliqinileyo. Eyona ndlela ifanelekileyo yokudibanisa i-HDPE kukusebenzisa i-thermal heat fusion, enyibilikisa iplastiki ngokwayo ukuze yenze i-joint.

Isizathu sokuba ungakwazi ukuncamathisela i-HDPE kungenxa yesayensi yayo yezinto eziphathekayo. I-HDPE ine-ukumelana okuphezulu kakhulu kwiikhemikhali kunye nezinyibilikisi, enye yeenzuzo zayo eziphambili. Le mpawu inye ithetha ukuba izincamathelisi zeekhemikhali, njengesamente ye-solvent esetyenziselwa i-PVC, azisebenzi. Azinakukwazi “ukuluma” kumphezulu weplastiki ukuze zenze i-weld. Ukuzama ukufumana “iglu” ye-HDPE yimpazamo eqhelekileyo kumaqela amatsha kwizinto. Indlela echanekileyo neyodwa eyamkelekileyo kushishino yokwenza i-joint esisigxina, yolwakhiwo kukudibanisa ubushushu. Le nkqubo isebenzisa isixhobo sokufudumeza esikhethekileyo ukunyibilikisa imiphezulu yemibhobho okanye izixhobo ezidityanisiweyo. Nje ukuba zikwimeko yokunyibilika, ziyatyhalwa kunye kwaye zibanjwe phantsi koxinzelelo. Njengoko iplastiki iphola, idibana ibe yinxalenye enye engenamthungo. I-joint ephumayo ayisiyonto nje yokutywina; yi-weld epheleleyo enamandla, okanye enamandla ngakumbi, kunepayipi yokuqala.

Yeyiphi indlela engcono yokujoyina i-HDPE?

Ukwazi ukuba awunakusebenzisa iglu, kufuneka uqonde indlela efanelekileyo yobungcali. Ukukhetha indlela efanelekileyo kubalulekile ukuqinisekisa ukuba umbhobho wakho uqinile, awuvuzi, kwaye uya kuhlala amashumi eminyaka.

Eyona ndlela ilungileyo yokujoyina i-HDPE kukusebenzisa i-heat fusion. Le nkqubo idala i-joint ehlala ihleli, i-monolithic joint eqinileyo njengombhobho ngokwawo. Iindlela ezimbini eziphambili zeziukuhlanganiswa kweempundukwiipayipi ezinkulu kunyeukuhlanganiswa kwesokhethikwiipayipi ezincinci kunye nezixhobo.

Ukuxubana kobushushu ngumgangatho ogqwesileyo we-HDPE kuba kususa eyona ndawo ixhaphakileyo yokusilela kuyo nayiphi na ipayipi: ijoyinti. Endaweni yokuxhomekeka kwizinto ezahlukeneyo ezifana ne-gasket okanye iglu, ijika iziphelo ezibini zibe yinto enye eqinileyo. Indlela ethile ixhomekeke kubungakanani bepayipi.

Ukuhlanganiswa Kweempundu

1. Iziphelo ezimbini zemibhobho zibotshelelwe kumatshini oqinisekisa ukulungelelana okugqibeleleyo.
2. Isixhobo sokusika esikhethekileyo sijonge iziphelo, nto leyo esenza zicoceke ngokugqibeleleyo kwaye zilingane.
3. Ipleyiti yeheater elawulwa bubushushu ibekwa phakathi kweziphelo, izinyibilikise kubunzulu obuthile.
4. Ipleyiti yeheater iyasuswa, kwaye iziphelo ezinyibilikisiweyo zicinezelwe kunye phantsi koxinzelelo olulawulwayo, nto leyo eyenza i-weld.

I-Socket Fusion

1. Isixhobo sokufudumeza esineentloko zendoda nezebhinqa ezifanayo sifudumeza umphandle wombhobho kunye nongaphakathi wombhobho ngaxeshanye.
2. Nje ukuba ifudunyezwe, isixhobo siyasuswa, kwaye umbhobho utyhalelwa ngoko nangoko kwisokethi yesixhobo sokufaka.
3. Ezi nxalenye zigcinwa ixesha elifutshane lokupholisa, nto leyo evumela ukuba iiplastiki zidibane ngokusisigxina.

Ingakanani ixesha lokuphila kombhobho we-HDPE?

Wenza utyalo-mali olukhulu kwiziseko zakho zophuhliso. Kufuneka uqiniseke ukuba izinto ozikhethileyo aziyi kufuna ukulungiswa okanye ukutshintshwa okubiza kakhulu kwiminyaka embalwa nje.

Umbhobho we-HDPE unobomi boyilo oluhlala ixesha elide lweminyaka engama-50, kodwa uqikelelo kunye nezifundo zehlabathi lokwenyani zibonisa ukuba unokuphila iminyaka eli-100 nangaphezulu. Ukuqina kwawo kuvela ekuchaseni kwawo okumangalisayo kokugqwala, ukuhlaselwa ngamakhemikhali, kunye nokudinwa komzimba, okuqinisekisa iindleko eziphantsi kakhulu zobunini.

Ubomi obude bepayipi ye-HDPE ayisiyonto nje ibango; yimiphumo yeempawu zayo eziphambili zezinto. Oku kwenza ukuba ibe lutyalo-mali olunobulumko kakhulu lwexesha elide, oluyinto ephambili kuvavanyo lwanoma yimuphi umphathi wokuthenga. Kukho izizathu ezahlukeneyo zokuba ihlale ixesha elide kangaka:

• Ayisebenzi ngokwekhemikhali:I-HDPE ayigqwali okanye ayidli njengemibhobho yesinyithi. Ikwamelana kakhulu neekhemikhali, ii-asidi, kunye nee-alkalis ezifumaneka emhlabeni nasemanzini, ngoko ke udonga lombhobho alunakonakala ngokuhamba kwexesha.
• Ayikwazi ukudinwa:I-HDPE yinto eguquguqukayo. Oku kuyivumela ukuba ikwazi ukufunxa ngokukhuselekileyo uxinzelelo oluphezulu, ukungcangcazela, kunye nokuhamba komhlaba okunokubangela ukuba imibhobho eqinileyo efana ne-PVC okanye intsimbi iqhekeke ize ingasebenzi.
• Ayikwazi ukurhawuzelelwa:Le nto iqinile kakhulu kwaye ibambelela kakuhle kwizinto ezirhabaxa ezinokuthi zigeleze ngaphakathi kumbhobho, njengesanti okanye ulwelo, oluqheleke kwezinye iindawo zamanzi.
• Amalunga Angavuziyo:Njengoko besixoxile, amalungu adityaniswe nobushushu aqinile njengombhobho. Oku kuphelisa ukulahleka kwamanzi kumalungu avuzayo, nto leyo eyingxaki enkulu yexesha elide kwiinkqubo ezindala ezisebenzisa amalungu anegesi okanye i-bell-and-spigot.

Isiphelo

I-Poly pipe sisiteketiso nje se-HDPE. Yinto egqwesileyo edityaniswe nokuxubana kobushushu, hayi iglu, enika ubomi benkonzo obufikelela kwiminyaka eli-100 nangaphezulu.
