IHDPE Pipe: ufakelo wezandla zabo, ingakumbi ufakelo kunye nemiyalelo

Imibhobho polyethylene ezi ubhetyebhetye ngenxa iimpawu ebalaseleyo mbandela. Iya isanda ezisetyenziswa kubomi bemihla ngemihla na umbhobho iHDPE. Ufakelo kungenziwa ngezandla zabo, ukuba benze zonke yimithetho. Akudingi izakhono ezizodwa.

iimpawu ezibonakalayo

Imfuneko kakhulu umbhobho iHDPE ebangelwe kwizinga eliphezulu impahla:

• lobushushu lomqolo - -50 ⁰ C ukuya +60 ⁰ C;
• ukumelana esidi obrak eendaba;
• luthambe eliphezulu namandla;
• conductivity thermal elisezantsi;
• Polyethylene ayilo umbexeshi yangoku yombane.

Ukusetyenziswa kwemibhobho

Ekhaya okanye cottage kwemibhobho iHDPE zenziwa:

• ugutyulo yamanzi;
• ubonelelo lwamanzi;
• igesi ukuya ekhaya;
• intambo emzileni zikagesi.

Ukukhethwa ngemibhobho

Kuba umbhobho kwimibhobho yamanzi aselwayo ukufumana enedayamitha elingagqithanga-60 mm kunye Ebubanzini bodonga ka-4 mm. Kufuneka zenzelwe kuxinzelelo abayisebenzisayo ulwelo kule nkqubo lingaphantsi kwe-1 MPA. Inzuzo na ukungabikho ngesinyithi kunye incasa yamanzi. Ukuba kufuneka kuxhotyiswe unikezelo ngamanzi ashushu, kubalulekile ukwazi ukuba xa amaqondo obushushu 80 ⁰ C polyethylene yenza naphezu ngakumbi ukhulisa uqala ukunyibilika. Kule uxhulumaniso kufuneka zikhethwe, PE80 kwibakala. Kuba imibhobho yamanzi ashushu ukuze zibhalwe okanye PE-RT PN20, bona ukumelana ukufudumeza ukuya 110 ⁰ C. To oku iimeko zokuphila kwanele.

Ukuba ukwahlula njengogwali ngenxa sonikezelo lwamanzi kunye noxinzelelo-free. Kuba kweemeko eziqhelekileyo zokusebenza zithathwa nomjelo bay m 25 ubuncinane 2 mm udonga ubukhulu. Ukuba umgca eziphambili osebnza phantsi koxinzelelo elungileyo kwaye ububanzi mkhulu kuno-25 mm, ithinjiwe iKiriyatayim njengento impompo kumbhobho intshi. Kuyo nayiphi na imeko, ukususwa kufuneka icandelo incinane umbane lulonke.

Iindlela ngemibhobho HDPE

Phambi ufakelo, ukukhetha indlela uxhulumano, olunokuba ngolu hlobo lulandelayo:

1. Yesiko - electrofusion okanye lempundu welding. Umchiza afunyenwe amandla efanayo naleyo kumbhobho ngokwayo.
2. indlela Yahlula - umsi, ucinezelo kunye uqhagamshelo esisangqa. iinkqubo eziyi- ezinjalo ndawonye lula kwaye ngabunye, kunokwenzeka ukuba alungise okanye ufakelo kwiindawo tight. Ukuxhumana zenziwa nge yaphukayo.

indlela Indibaniselwano kukhethiwe kuxhomekeke zinto zilandelayo:

• pipe ngobubanzi;
• uhlobo ukusebenza: free-flow, uxinzelelo, iingcingo ezihamab phantsi;
• ukusetyenziswa okufanelekileyo kwezivalo izinto ezahlukeneyo kwaye ngobubanzi ezahlukeneyo;
• isabelo lula;
• ubukho kwezixhobo welding.

Eside kakhulu afunyenwe welding kunye noqhagamshelo flanged. Emkhonweni threaded ngetywina ukumelana ntshikilelo. Ukufakelwa kwemibhobho iHDPE sonikezelo lwamanzi kunye nezilinganisi ucinezelo idla ngokwenziwa emiyezweni home kweenkqubo zokunkcenkceshela.

Umdibaniso olubuthathaka kakhulu - ukuvuleka. Zisetyenziswa kuphela imibhobho ezingezo-uxinzelelo ngaphandle xa uxhulumaniso welding.

izixhobo ucinezelo for njengogwali HDPE: ukuyinyusa

Kuba imibhobho iHDPE kusetyenziswa izixhobo ikakhulu zeplastiki, kodwa kukwakho ezahlukeneyo ophumelelayo ngentsimbi, intsimbi, ubhedu, nezobhedu. Ahluke kuyilo kwaye omthuqwa, azinamsonto, ngoqhagamshelo cofa. Kuba Imibhobho yeplastiki ziya kukhethwa kusetyenziswa izixhobo ucinezelo, apho nitrogen lwenziwa nokubotshwa isangqa ekwahlulweni iplastiki eqinileyo kunye ngeenotshi uphawu - retaining amakhonkco uphawu.

Njengezinye izixhobo kokuxhuma, izifakelelo ucinezelo ezo iintlobo ezininzi:

• coupling - yoqhagamshelo zemibhobho ubukhulu ngokulinganayo ngakulo;
• lenguqu - ngokuba nokubopha iziphelo kwemibhobho, le ngobubanzi zazo ezahlukeneyo (inguqulelo 'metal-PE ");
• esokuqala engile - lwenziwa kubume twist 45-120 ^0;
• Tees, osibonayo - ukudala amasebe;
• isinxibelelanisi - isixhobo loqhakamshelwano umbhobho ukuya umbhobho;
• plug - ngokuba livale eziphelweni umbhobho.

Phambi zomzila unikezelo lwamanzi kufuneka kuqala uzobe umzobo zonke izixhobo zayo lwezivalo. Kumbhobho eyandisiweyo ithande ukuba aliqhawule ukuze kukhuselwe nge okubamba okanye licinezelwe ibe karhulumente eyandisiweyo iintsuku-2.

Ukuba ikhethiwe zokufaka yofakelo Umbhobho iHDPE wayedla kunye nezilinganisi ucinezelo.

1. I-pipe lisikwa yobungakanani wacela isixhobo esisodwa. Ungasebenzisa hacksaw rhoqo, kodwa ekupheleni elifanayo tyaba kwaye lisuswe Isipha.
2. Hole elungelelaniswe Skena njengoko ukwakheka kwalo elimbhoxo akwamkelekanga. chamfer lwangaphandle ekupheleni.
3. kakuhle umzimba efanelekileyo liqhagamshelene nelembande, ukuze kungabikho monakalo irabha ezitywine. kuya kuba lula Ukutyala ukuba yokunyakamisa kuhlangana khona.
4. Izandla liqiniswe Union nut. Ungasebenzisa isitshixo ukubonelela unxulumano eziyimfuneko ukuze yobunzima.
5. Ukuze le nkqubo umbhobho yesibini ngokuphindaphindiweyo.

izixhobo Udibaniso ucinezelo esetyenziswa lula, xa ufakelo kwemibhobho iHDPE kweli lizwe. Le nkqubo kulula ukuba bahlanganise entwasahlobo kwi sayithi kwaye ukuncothula ekwindla.

unxibelelwano Plug-in kwiindawo tight ayenziwa. Kukho elula ukusebenzisa iwelding kunye isifudumezi eyakhelwe-ngaphakathi. pipe Ixhume kufaneleka 2, nalapho luvuliwe, kwaye zokufudumeza kwenzeka welding ukwenza indibano-sifuba. Ixabiso iphezulu isixhobo, kodwa ndlela iphumelela kwaye isoloko isetyenziswa.

Nangona nokwenzeka sichitha e lwezilinganisi ucinezelo kufuneka indawo irabha ezitywine xa ufaka. Oku kuya kuqinisekisa ukuthembeka eliphezulu design.

uqhagamshelo esisangqa

Xa pipe iHDPE efakiweyo obandayo ukuba ububanzi 40 mm bhetele kwenziwa flanges yesinyithi. Ukuze wenze oku, Wayixakaxa ngohlangothi umbhobho mgawuli kwindawo efanelekileyo ubeko ogqityiweyo. Emva koko ofunwa sleeve yeplastiki ngeeplanga, bayimisa flanges yesinyithi. Enye indlela ukubutha esisangqa kumbhobho ucinezelo ukuze kukhuselwe Polymer inxenye kakuhle entlanganweni. Emva koko, lo esisangqa esiqhelekileyo, encamathele yi izikhonkwane kunye nezitshixo neqhekeza efanayo zixhonywe ekupheleni kombhobho ngentsimbi ye.

uqhagamshelo Flanged kuvumela kwemithambo, nabalawuli, iivelufa kunye nemibhobho phakathi kwabo.

ukuxhumana nge welding

Kanye njengokuba iimveliso yesinyithi kufuneka omthuqwa umbhobho iHDPE. imveliso ngoncedo nezixhobo ezizodwa kunye zokufudumeza yombane joint yoFakelo izandla.

1. Wahlahla isiphambuka, kwaye ulungiselela izixhobo ukuwelda.
2. Misela iparameters welding.
3. Xa le mibhobho ishukunyiswa ezisisigxina amabamba umatshini ukuwelda kunye nendawo. Iziphelo zoomatshini phambili.
4. Izifudumezi zifakwa phakathi iityhubhu, ekuthe mmandla zaphela.
5. Iziphelo yengcinezelo kwanciphisa iya kuhlala injalo de zokupholisa.
6. Imibhobho acatshulwe kwi-umboniso.

Ufakelo kubiza Imibhobho iHDPE yi welding ixhomekeke ubukhulu, kodwa ixabiso lika 63 mm kunye ngexabiso elifanayo idla malunga 200 engange. ehlanganyelwayo.

Xa kusetyenziswa coupling zombane iindleko ufakelo ziyafana kuba iwelding umhlana; kodwa ixabiso lakhe liphezulu. Ngenxa yoko, iindleko zemveliso omkhulu.

iimvavanyo hydraulic

Operability umbhobho wamanzi aqokelelweyo ikhangelwe ngokuzalisa ngamanzi ngenxa 2 h. Emva koko, uxinzelelo kule nkqubo kuvuswa kwaye egcinelwe imiz-30. Yombhobho ke kuhlolwa ukuvuza.

Xa umsebenzi karhulumente le nkqubo rhoqo. Xa babehlanganisene kakuhle kuya kusebenza ixesha elide ngokwaneleyo.

Iimpazamo ngexesha imibhobho ibandla HDPE

1. Kubalulekile ukuthatha ingqalelo ukwanda yomgama kombhobho kwimiphumo lobushushu. Ukuba uyilibale, imibhobho ngaphakathi kwamandla ngaphezulu kunesiqhelo, leyo kunciphisa ubomi inkonzo yabo.
2. enkulu kakhulu umgama phakathi anchorages ubangela unokukhawuleza conduit ekhokelela ukusilela yayo kwexesha.
3. Imibhobho kuhlangana kuphela usambathisa.
4. Ukuze ayakhekanga phezu komhlaba condensate, lusidla imijelo yamanzi ashushu okanye abandayo zigqunyiwe.
5. Xa wayemenza ofanelekayo zezikhali ukuba ipipi ukuya stop wangena. Xa ukhulula nut ukuba ekupheleni, yaye emva koko ngokuqinileyo zidudulelwe ityhubhu isinxibelelanisi, oko unako ukungena kakhulu ngokwaneleyo. Xa ufakelo yenziwe imibhobho iHDPE ngezandla zakhe kweli lizwe ngenxa iinkqubo zokunkcenkceshela, ezivuzayo azikho ziyingozi, kodwa ayamkelekanga ukuba ubonelelo lwamanzi zasekhaya. Enoba neziphumo kwiimeko zombini kuyimfuneko ukwenza unxulumano tight.
6. Over-ukuqinisa iadaptha, esa entshabalalweni okanye n'ekiweebwayo pads iindawo ufakelo.

isiphelo

Xa ifakiwe umbhobho iHDPE, hlangana kwenziwa ikakhulu yi welding okanye ucinezelo izixhobo. Ngokuxhomekeke kwimithetho yocwangciso Uxhulumaniso kuba ekhaya yaye elide iminyaka emininzi.
