Pupa kirihou whakakikoruatia ki waho PE
Waho PE hiato pani putorino kirihou, pania (hurihia) kirihou hiato paipa maitai kahore he here diameter, te matotoru o te paparanga ararewa e taea hoki te whiriwhiri arbitrarily, kia rite ki te waikura tikanga reo, whiriwhiri rerekē matotoru ararewa, roa taea hoki tae 6-12 mita;Ko te diameter nominal taua, pani (hurihia) kirihou hiato maitai putorino ararewa ko te tikanga i waenganui i 0.5-1mm, mata ngongo maeneene, he iti noa te whakarea waku, a he iti hoki te whakarea waku, he iti te mate wai i roto i te ngongo, he nui te rere o te tuku, ki te whakatutuki i te penapena kaha.I roto i nga tau tata nei, kua whakamahia whānuitia nga putorino maitai torino anti-corrosion i roto i te hanga supply wai me te waikeri, inu wai tohatoha pipelines engineering, mana ahi, mo te tino paipa paipa maitai putorino i mua i te whakamahi wera piauau piauau putorino maitai, maha hapori, hotels, Ko nga whare tari kei te whakamahi i nga putorino rino anticorrosive paura epoxy me nga taha e rua kua whakakikoruatia ki te kirihou ka whakamahia ki roto, ki waho hoki hei taonga paipa ahi, he ataahua tona ahua me te roa, Kua waiho hei hua nui mo nga umanga ka puta mai i te rautau 21.PE roto EP paninga kirihou maitai ngongo hoko ngaio o te paura pani kirihou ngongo maitai tāpiri mura mura me te whakarerekē epoxy kapia paura, he pai ake te ātete pāmahana o te paninga, i roto i te whakamahi wā-roa e kore e tahuna, e kore e ngohengohe.
Waho Pe Composite paninga Kirihou Pipe, Painga
Ko te kiriata peita o te paura epoxy anticorrosive ngongo maitai he uaua, he wai atete me te kore-paitini.He kaha te piri, he pai te piri i waenga i te kiriata peita me te kiriata peita.He pai te aukati i te waikura me te aukati wai, te whakamahi i nga rauemi mata anti-waikura pai, hei whakarite i tana mahi anti-waikura.He pai te kaha o te miihini, te kiriata uaua, te aukati abrasion me te awangawanga paanga.Te ihirangi totoka teitei, te kiriata matotoru.Ko te hanganga ngota o te putorino rino anticorrosive paura epoxy e whakaatuhia ana e nga roopu epoxy kaha i roto i te mekameka ngota, ka taea te tu ki te pito, waenganui, mowhiti ranei o te mekameka ngota.
Na te kaha o nga roopu epoxy i roto i te hanganga rapoi, ka taea e ratou te whakawhiti ki nga momo momo rongoa rongoa hei hanga i nga polymers korekore me te whakauru me te hanganga whatunga e toru-ara.Ko nga paninga paura thermosetting te nuinga e whakamahia ana i roto i nga whenua rereke: paninga paura epoxy, paninga paura epoxy phenolic, paninga paura polyester, paninga paura epoxy- polyester.I roto ia ratou, epoxy paura paninga ko te momo wawe o te tono, Ko hoki te hanga o nāianei o kirihou paura paninga, whakamahia whānuitia i roto i te tukanga rehu electrostatic, i roto i te paninga whakapaipai whai wāhi tino nui;Na te nui o te aukati waikura matū, ka whakamahia te paura paura epoxy phenolic mo te paninga anti-corrosion.
Ko nga Whakakikorua Paura Thermoplastic Ko te nuinga
Te paninga paura polyethylene, te paninga paura polyvinyl chloride, te paninga paura polypropylene, te paninga paura polyether chlorinated, te paninga paura nylon, te paninga paura polyphenylene sulfide, me etahi atu, he painga me nga ngoikoretanga o enei paninga paura thermoplastic.Ko nga kirihou thermosetting he pai ake te whakamaarama me te makuku na te iti o te taumaha ngota, ka kaha te piri ki te tinana ngongo i te wa e whakakikoruatia ana te ngongo maitai, a ka taea te hanga i te ngongo maitai whakakikorua kia whiwhi i te mata kiriata kirihou maeneene.Ko nga kirihou thermosetting e whakamahia ana ko: kapia epoxy, kapia phenolic, kapia amino me etahi atu.Ko te matotoru o te pakitara paninga kei waenganui i te 100 microns me te 500 microns, ko te tikanga 350 microns.
I waho PE hiato putorino kirihou pani, 1. Hauora, kore-paitini, kahore tauine, kahore tupuranga o microorganisms, whakarite te kounga o te wai 2. 3. Ko te tukanga tāuta he pakeke, watea, me te nohopuku, me te hononga ki te putorino piauau noa he he rite tonu.4. He pai te parenga huarere.5. pakitara paipa maeneene, whakapai ake i te pai o te kawe, te roa o te mahi.
Pupa kirihou whakakikoruatia ki waho PE, aratau Hononga:hononga miro: whakamahia te waea miro a-ringa, te miihini ringaringa waea hiko ranei hei tukatuka i te miro paipa, kia aro ki te whakamatao i te wa e tukatuka ana;Te hononga flange, te ine i runga i te waahi, te tuhi i te pipeline mapi tukatuka raina kotahi, te paninga tukatuka, te raima kirihou, ka haria ki te waahi whakaurunga;Ka taea te whakamahi i te putorino maitai me te paipa paipa kore whakakikoruatia, ka taea te whakamahi i roto i te mara, te whakapiri flange, te whakakotahi i te pipeline, katahi ka wetewetehia mo te paninga, te tukatuka kirihou raina, ka haria ki te waahi whakaurunga;Me pai ake nga taputapu paipa kirihou kua oti te whakakikoruatia;Ka pehia nga awaawa e te miihini hurihuri, a, ko nga awaawa kia rite ki nga paerewa e tika ana.
