Sab nraum 3LPE Txheej DIN 30670 Sab hauv FBE Txheej
Product Description
Cangzhou Spiral Steel Pipes Group Co., Ltd muaj 4 kab ntau lawm ntawm anticorrosion & thermal rwb thaiv tsev los ua 3LPE txheej thiab FBE txheej.Qhov siab tshaj plaws sab nraud txoj kab uas hla tuaj yeem yog 2600mm.
Cov coatings yog tsim rau kev tiv thaiv ntawm faus los yog submerged steel kav ntawm tsim kub ntawm -40 ℃ to +80 ℃.
Cov txheej txheem tam sim no qhia txog qhov yuav tsum tau ua rau cov txheej txheem uas siv rau cov kav hlau welded thiab fittings siv rau kev tsim cov kav dej rau kev xa cov kua lossis cov pa roj.
Kev siv tus qauv no ua kom ntseeg tau tias PE txheej muab kev tiv thaiv txaus tiv thaiv cov khoom siv thermal thiab tshuaj lom neeg thaum lub sijhawm ua haujlwm, thauj, khaws cia thiab teeb tsa.
Extruded coatings muaj peb txheej: ib qho epoxy resin primer, ib tug PE nplaum thiab ib tug extruded polyethylene txheej txheej.Cov epoxy resin primer yog siv los ua hmoov.Cov nplaum tuaj yeem siv los ua hmoov los yog extrusion.Rau extruded coatings ib tug sib txawv yog ua los ntawm lub tes tsho extrusion thiab daim ntawv extrusion.Sintered polyethylene txheej yog ib qho los yog ntau txheej txheej.Cov hmoov polyethylene yog fused mus rau lub preheated tivthaiv kom txog rau thaum lub thickness ntawm lub siab xav tau mus txog.
Epoxy resin primer
Lub epoxy resin primer yuav tsum tau siv rau hauv cov hmoov hmoov.Qhov tsawg kawg nkaus txheej thickness yog 60μm.
PE nplaum
Cov nplaum PE tuaj yeem siv rau hauv cov hmoov nplej los yog extruded.Qhov tsawg kawg nkaus txheej thickness yog 140μm.Lub tev lub zog yuav tsum tau sib txawv nyob ntawm seb cov nplaum tau siv los ua hmoov los yog extruded.
Polyethylene txheej
Polyethylene txheej yog siv los ntawm sintering los yog los ntawm lub tes tsho los yog daim ntawv extrusion.Cov txheej yuav tsum tau txias tom qab daim ntawv thov kom tsis txhob plam deformation thaum thauj.Nyob ntawm seb qhov loj me me, muaj qhov sib txawv yam tsawg kawg nkaus rau cov txheej txheem tag nrho cov tuab.Nyob rau hauv cov ntaub ntawv ntawm cov neeg kho tshuab loads lub minimu txheej thickness yuav tsum tau nce los ntawm 0.7 hli.txheej txheej tsawg kawg nkaus yog muab rau hauv cov lus 3 hauv qab no.
