3-txheej polypropylene (3LPP) coated kab yeeb nkab

3LPE Coated Steel Yeeb Nkab, LossisPeb {- txheej polyethylene coated steel yeeb nkab, Yog hom corrosion - Resistant pipeline dav siv nyob rau hauv kev lag luam xws li roj, kev tsim tshuaj, thiab khoom siv dej.

 

Daim ntawv thov ntawm cov txheej:

Kev npaj saum npoo ntawm cov yeeb los ntawm sandblast tu (SSPC - sp10 / nace No.2 / iso 8501-1 sa {{4} 05 59 00)

Txuas ntxiv rau cov yeeb nkab cua sov fusion epoxy hmoov yuav tsum tau thov

Extruded nplaum yuav tsum tau thov dua cov yeeb nkab.

Thaum kawg extruded polypropylene (MDPP lossis HDPP) txheej yuav tsum tau thov dua cov nplaum txheej.

Tas nrho cov txheej tuab yog feem ntau <3.0 hli rau cov yeeb nkab dia <24 "thiab 3.3 hli rau cov yeeb nkab 32" & saum toj)

 

Image result for Three Layer Poly Ethylene/ Propylene (3LPE/ 3LPP) coating 3LPE/ 3LPP coating system is a multilayer coating composed of three functional components: a high performance fusion bonded epoxy (FBE), followed by a copolymer adhesive and an outer layer of Medium Density Polyethylene (MDPE) or High Density Polyethylene (HDPE), which provides protection against external corrosion. The codes and standards for 3LPE are ISO 21809-1, DIN 30670 or CAN/CSA Z245.21. Fusion Bonded Epoxy (FBE): First layer of FBE shall be 150 microns thick. Adhesive: Second layer of extruded co-polymer adhesive, 200 microns thick. Polyethylene (MDPE/HDPE): Third layer of extruded polyethylene (MDPE/HDPE) or polypropylene (MDPP/HDPP), 1.6 – 2.95 mm thick. Application of Coating: Surface preparation of pipe by blast cleaning, subsequent to pipe heating fusion epoxy powder shall be applied and after that extruded adhesive shall be applied over the pipe. Finally extruded polyethylene (MDPE or HDPE) layer shall be applied over the adhesive layer. Total coating thickness is generally < 3.0 mm for pipe dia < 24
