The construction of a new anticorrosion external coating line for large diameter pipes began at TMK’s Volzhsky subsidiary. The maximum capacity of the line is 650,000 tons of pipes annually. These new facilities will supplement the two existing anticorrosion external coating lines for large diameter pipes at Volzhsky.
The constructing line allows applying one- and two-layer FBE coatings; two- and three-layer PE coating and two- and three-layer polypropylene coating. The external coating extends pipelines life time of a minimum of 30 years.
This coating equipment technologically is designed to process pipes with up to 42 mm in wall thickness. Thus, the new coating line will match the capacity of a new longitudinal welded large diameter pipe facility also currently being built in Volzhsky. The works to install the complex should be finalized and operations of longitudinal welded large diameter pipes are planned to start in 3rd quarter 2008 followed by launching new section of an anticorrosion coating in 4th quarter 2008.
