Dow Europe GmbH has announced recently that it will take part in AMI's 2nd International Conference Pipeline Coating 2010, an event that focuses on technology and market developments in the global pipeline protection industry.
During the 3 day conference, to be held on February 1st 2010 to February 3rd 2010 in Vienna, Dow will introduce its new offer to the steel pipe coating industry with a presentation entitled "A High Density Polyethylene and Grafted Adhesive Solution for Steel Pipe Coating". It will be held by Dr Olaf Henschke, technical leader for steel pipe coating on February 3rd 2010.
Mr Dragan Visekruna market manager at Dow for pipe applications in Europe, the Middle East, India and Africa said that "Dow will demonstrate its advanced solutions for pipeline protection, and introduce its new offer to the steel pipe coating industry: the recently launched top-coat and adhesive polyolefin materials for three-layer steel pipe coating systems."
He added that "DOW HDPE 12110G, a black high density polyethylene top coat material, and AMPLIFY GR 320 Functional Polymer, a grafted adhesive resin will contribute to the long term corrosion protection of oil and gas pipelines."
The DOW HDPE 12110G / AMPLIFY GR 320 system in combination with different fusion bonded epoxy materials demonstrated in industrial trials that they meet stringent performance requirements for coating large diameter steel pipes. Reference projects indicate a good long-term performance of the Dow HDPE 12110G / AMPLIFY GR 320 system that exceeds the requirements of DIN 30670 and of other national and customer standards.
A three layer steel pipe coating system comprised of DOW HDPE 12110G and AMPLIFY GR 320, together with an FBE bonded directly on the steel pipe, can help deliver good coating performance for the lifetime of oil and gas pipelines while also offering excellent processability on conventional pipe coating lines.
As a top coat material, DOW HDPE 12110G in a three layer steel pipe coating system offers excellent environmental stress crack resistance (ESCR), excellent physical properties and easy processing. AMPLIFY GR 320, Dow's adhesive, offers excellent adhesion to both the FBE and top-coat layers in a three-layer coating system, in addition to easy processing, mechanical strength at high and low temperatures, good temperature resistance and low water absorption.
The key objective of steel pipe coating is to prevent or minimize the possibility of pipeline corrosion as a result of extreme external conditions, mechanical impacts or degradation by heat or UV irradiation. To help meet this performance requirement, critical parameters for polyolefin materials used in three layer steel pipe coating systems are excellent adhesion and adhesion retention, durability, crack resistance and long term stability, together with low levels of built in stress during the coating process.
