Umbhobho weNtsimbi woMgangatho oPhakamileyo
Umbhobho weNtsimbi woMgangatho oPhakamileyo

(2) Ngokwenkqubo yokwenziwa, umbhobho odityanisiweyo unokwahlulwa ube ngumbhobho wentsimbi odityanisiweyo othe tye, umbhobho wentsimbi ojikelezayo, umbhobho wentsimbi odityanisiweyo, umbhobho wentsimbi odityanisiweyo kunye nombhobho odityanisiweyo wentsimbi wokwandisa.
Ngokwemilo, imibhobho yentsimbi inokwahlulwa ibe: umbhobho ojikelezayo, umbhobho wesikwere, umbhobho oxande, i-octagonal, i-hexagonal, i-D-shaped, i-pentagonal kunye neminye imibhobho yensimbi ekhethekileyo, icandelo elinzima lemibhobho yentsimbi, i-double concave steel pipes, i-petal emihlanu. imibhobho yentsimbi ye-quincunx, imibhobho yentsimbi ecolekileyo, imibhobho yentsimbi exonxiweyo, imibhobho yentsimbi yembewu yemelon, imibhobho yentsimbi yeconvex ephindwe kabini, njl.
Umbhobho wensimbi unokwahlulwa ube: umbhobho wentsimbi wemibhobho, umbhobho wentsimbi wezixhobo ezishushu, umbhobho wentsimbi kwishishini lomatshini, umbhobho wentsimbi wepetroleum kunye ne-geological drilling, umbhobho wentsimbi yesikhongozeli, umbhobho wentsimbi kushishino lweekhemikhali, umbhobho wentsimbi ngenjongo ekhethekileyo, njl. I-anti-corrosion classification yodonga lwangaphakathi: ukusonga ulwelo lwe-epoxy ukutyabeka ipn8710 anti-corrosion kunye ne-folding fusion ebond epoxy powder anti-corrosion.
Ulwahlulo lwe-anti-corrosion eludongeni lwangaphandle: ukugoqa i-2PE / 3PE i-anti-corrosion, i-pe-layer PE anti-corrosion kunye ne-epoxy coal asphalt anti-corrosion.Umgangatho ochasene nomhlwa: FBE epoxy powder anti-corrosion iya kuthobela SY / t0315-2005 iinkcukacha zobuchwephesha zomaleko omnye wodibaniso oludityaniswe ne-epoxy powder yangaphandle yokwaleka kombhobho wentsimbi, 2PE / 3PE anti-corrosion iya kuhambelana nomgangatho wobugcisa we-GB / t23257-2009 i-polyethylene yangaphandle yokugquma yombhobho wentsimbi engcwatyiweyo, umgangatho wokususa umhlwa we-anti-corrosion: ukuqhushumba kwesanti kumphezulu ongaphandle wombhobho wentsimbi kuya kufikelela ku-SA2 1/2 ngokweemfuno ze-GB / t8923-2008, kunye nobunzulu beenkozo ze-ankile ubuso bombhobho wensimbi iya kuba yi-40-100 μ m.
Izinto ezisisiseko zemibhobho yentsimbi echasene nomhlwa ziquka imibhobho ejikelezayo, imibhobho yomthungo ethe tye, imibhobho engenamthungo, njl.njl e-China, zisetyenziswa ngokubanzi kwiinkalo zobunjineli bemibhobho efana nokuhanjiswa kwamanzi omde, i-petroleum, ishishini lemichiza, igesi yendalo, ubushushu. , ukucocwa kogutyulo, umthombo wamanzi, ibhulorho, ubume bentsimbi, ukuhanjiswa kwamanzi olwandle kunye nokupakisha.
Ukongeza ekuphuculeni ubomi benkonzo yombhobho wensimbi ngokusebenzisa i-anti-corrosion, iphinda ibonakaliswe kule miba ilandelayo:
1. Hlanganisa amandla omatshini wombhobho wensimbi kunye nokumelana nokubola kweplastiki;
2. Udonga lwangaphandle olungaphandle lungaphezulu kwe-2.5mm, luxhathise ukukrala kunye nokungqubana;
3. I-coefficient ye-friction yodonga lwangaphakathi luncinci, i-0.0081-0.091, ukunciphisa ukusetyenziswa kwamandla;
4. Udonga lwangaphakathi luyahlangabezana nemigangatho yezempilo yesizwe;
5. Udonga lwangaphakathi luhamba kakuhle kwaye alulula ukukala, kunye nomsebenzi wokuzicoca.
