300um FBE Coated API5L X42 Seamless Line Pipe
Standard: API5L PSL1
Coating: CAN CSA Z245 20-2010 FBE 300um
Size: OD273.1mm*WT 9.27mm/Others
FBE coating materials is a thermosetting material. it is consisit of solid epoxy resin,Curing agent and various additives by mixing,grinding.when performing,steel tube was heated to 220-230℃,then by electrostatic adsorption method ,FBE powder is sprayed on the surface of the pipe,heated and cooled melt adhesive curing ,Single-layer FBE coating thickness is about 300-500um,DPS(double layer FBE)thickness was controlled in 450-1000um.
FBE coating has the properties of excellent adhesive strength,high insulation resistance,oil stress,anti-aging,anti-cathode stripping,anti high temperature,resistance to bacteria and samll cathode protection current(only1-5uA/m2,and etc.but there are also poor performances against mechanical impact ,high water absorption and other shortages.
Our FBE/DPS coating perform the standards as per Y/T0315,CAN/CSA Z245.20,AWWA C213,Q/CNPC38.etc
Use: Widely used in land,underwater pipeline anticorrosion.
