I-DIN 30670-1yinkqubo yokukhupha enemigangatho emithathu evelisa i-polyethylene (3LPE) upende phezu komphezulu we-longitudinal okanye spirally welded kunyeimibhobho yentsimbi engenamthungoukubakhusela ekuboleni.
Isetyenziswa kakhulu kwiinkqubo zemibhobho ezigqunywe okanye ezingaphantsi kwamanzi ukuze kuthuthwe ulwelo okanye iigesi.
Qaphela: I-DIN 30670 yahlulwe yangamacandelo amabini kuhlelo lwamva nje luka-2024 ngokuxhomekeke kwinkqubo yemveliso, oko kukuthi i-DIN 30670-1 igubungela ipayipi kunye neengubo ze-polyethylene ezikhutshwe kwi-wound, kwaye i-DIN 30670-2 igubungela iintlobo ezitshiziweyo kunye nezitshiziweyo ngelangatye.
Zahlulwe zibe ziintlobo ezimbini ngokobushushu boyilo, ezizeziuhlobo u-N kunye nohlobo u-S.
| Uhlobo | Ubushushu boyilo (°C) |
| N | -20 ukuya ku + 60 |
| S | -40 ukuya ku + 80 |
kwayeI-ISO 21809-1ihambelana neklasi A kunye neklasi B, ngokulandelelanayo.
Umaleko woku-1 Umaleko we-epoxy resin, umgubo we-epoxy resin kufuneka usetyenziswe.
Umaleko wesibini oncamathelayo, onokuba ngumgubo okanye ogqunywe ngaphandle.
Umaleko wesithathu Umaleko wePolyethylene, inkqubo yokukhupha iityhubhu, okanye inkqubo yokukhupha iingqiniba.
Ukukhupha ityhubhu:
Kule nkqubo, izinto ze-polyethylene zikhutshwa ngqo kwimo yetyhubhu eqhubekayo, ize ibekwe kwisokhethi kumbhobho wentsimbi.
Le ndlela idla ngokusetyenziswa kwiipayipi ezincinci kwaye iqinisekisa ukufana kunye nokuqhubeka kokwambathisa.
Ukukhupha umoya:
Kule nkqubo, i-polyethylene ikhutshwa ngendlela yestrip ize ibotshelelwe kumphezulu wombhobho wentsimbi.
Le ndlela ifanelekile kwiipayipi ezinkulu okanye ezingezizo ezisemgangathweni kwaye ivumela ukugqunywa okuguquguqukayo kwiipayipi ezinzima okanye ezinkulu.
Ngokuxhomekeke kwiimfuno ezithile zeprojekthi, umaleko owongezelelweyo wokhuselo loomatshini ungongezwa kwi-3LPE.
Izinto ezisetyenziswa rhoqo ziqukaikhonkrithi(jonga kwi-ISO 21809-5),iplastiki eqiniswe ngefayibha yeglasi, okanye i-samente mortar(jonga kwi-DN N 30340-1).
Ukuqinisekisa ukuba i-shear iqinile kakuhle, kuyimfuneko ukurhabaxa okanye ukucinezela umphezulu we-polyethylene.
Unyango olunjalo lunceda ukwandisa ukunamathelana phakathi komaleko okhuselo olongezelelweyo kunye noqweqwe lwe-polyethylene.
Ubukhulu Bomaleko we-Epoxy Resin
Ubuncinane i-80um.
Ubukhulu Bomaleko Oncamathelayo
Ubuncinane i-150um.
Ubukhulu obupheleleyo bokugquma
Ngokuxhomekeke kububanzi obuqhelekileyo bombhobho wentsimbi, ubukhulu bomaleko wokukhusela ukugqwala buya kwahluka.
Ngobukhulu obupheleleyo beleyara ye-3LPE, i-DIN 30670-1 yahlulahlula iiklasi ezintathu ukuze ihlangabezane neemfuno ezahlukeneyo zokwakha.n,v, kunye no-s.
Ibanga n: Kwiimeko eziqhelekileyo, ubukhulu be-grade n buhlala banele.
Kwizinto zokugquma ezenziwe nge-polyethylene, ubukhulu be-1 mm busetyenziswa ikakhulu ekukhuseleni ukugqwala, ngelixa ubukhulu obuseleyo busetyenziswa ukuphucula amandla okuthwala umthwalo womatshini womaleko okhuselayo.
Ibanga v: Ukuba umthwalo woomatshini uyanda (ukuthutha, ukugcinwa, ukubeka, umgangatho othile, iimfuno ezandisiweyo), ubukhulu obuncinci bokugquma kufuneka bunyuswe nge-0.7 mm, oko kukuthi v = n + 0.7 mm.
Amabanga: Ubukhulu obukhethekileyo bokugquma obungaphezulu kune-v bunokuvunyelwana ngabo ukuhlangabezana neemfuno zeprojekthi ethile, kwaye ubukhulu obunjalo bokugquma obulungiselelweyo buphawulwa njenge-Grade s.
I-150mm ± 20mm, i-engile ye-bevel yobukhulu be-coating ayifanele ibe ngaphezulu kwe-30°.
Iileya ze-epoxy kunye ne-adhesive mazisuswe ubuncinane kwi-80 mm ukusuka kwisiphelo sepayipi. Ileya ye-epoxy mayishiywe iphuma kwisiphelo sepayipi egqunywe yi-polyethylene ubuncinane ubuncinane kwi-10 mm.
Ukuze ubone ubude, linganisa ukusuka kumphezulu wengcambu yombhobho ukuya ekuqaleni kwesiphelo esinqumlekileyo somphezulu wokukhusela ukugqwala.
