[MW:13453] RE: 13452] 3LPE coating

Dear Wajeed,

 

Just of interest, is it require 3LPE coating (Including Fusion Bond Epoxy(FBE) on  SS 304?

 

Shall I know the application? Who is the manufacturer doing this job (for 3” dia means very small in dia)? Is the manufacturer is having the setup for 3LPE for 3” dia?

 

Further preheating to 400 is not required for 3LPE – (1^st layer – FBE) just 180 – 200 Deg is sufficient, and

further 3LPE will be done while pipe is on rotation mode so longitudinal deflection chances are less and in 3LPE improper coating chances are very less, -

 but only doubt on the manufacturer about the expertise for doing of 3” dia

 

 

Thanks and Regards................?

Dear Experts

 

Pipe 3” wall thickness 3.05mm

Material SS 304

 

I wanted to coat external coating of 3 layer polyethylene by heating the pipe with 400 deg centigrade

 

1.       Please let me know due to less wall thickness of pipe is there any longitudinal deflection while rolling the pipe

2.       Is there any improper coating due to temp variation from super heater to coating die

 

In case yes, please let me know the solution for the same and please suggest related other coating which must comply the 3 layer polyethylene coating

 

 

Regards

Wajeed Ahmed
