Commercial advantages of CRA lined pipe

Mechanically lined pipes are cost attractive alternatives to the traditionally used Corrosion Resistant Alloy (CRA) pipes or metallurgically bonded clad pipes. This especially applies when it is combined with the reel-lay installation method for the following reasons:

l  Significantly lower procurement costs Faster delivery time  www.bobpipe.com

l  Availability of 12 m long joints, even for small outside diameter pipes, which may result in lower welding costs

l  Lined pipes not susceptible to Hydrogen Induced Stress Cracking (HISC)

l  Lower susceptibility to yield strength de-rating than some CRA pipes, at elevated temperature

l The patented novel design enables safe reel-lay at atmospheric pressure, hence there is no impact on normal reel-lay operations

Each lined pipe’s joint extremity is terminated by a seal overlay weld, which provides greater operational flexiblility during fabrication and in the offshore installation phase www.bobpipe.com
