Hello Richard Sir,

Actually i had a doubt regarding pipe support friction and you had clarified the same and stressed on the point that Friction forces are likely to get vary through the lifetime of the piping.That is you emphasized on the point that the friction forces will increase after some years due to rust,dirt etc..

I have a small confusion over here, in one of the Technical papers it had been mentioned that the friction effect gets shaken off after long period of operation (this is discussed in the conclusion of the paper).Can you please throw some light on this.
