Corrosion protection of coated carbon steel pipes

the provision of the white water canoe centre. The company recommends protecting pipe joints with its range of Canusa heat shrink sleeves. The heat activated/ PE wraps for corrosion protection of all types of jointing method are quick to install, as there is no need to prime or profile the pipe. Carbon steel pipeline installations can also be cathodically protected if low resistivity soils are present. Welded steel pipes, being electrically connected, are very simply and cheaply protected by sacrificial anode or other cathodic protection systems. Once in the ground, a coated carbon steel water pipeline will provide an extended service life. Combined with cathodic protection, the water utility has a secure, well-protected asset. FT Pipeline Systems offers a complete range of steel water pipes and fittings in an extensive range of diameters and joint types, along with field joint protection sleeves. FT Pipeline Systems Ltd – UK Website: www.ftpipelinesystems.co.uk All machining units are directly driven by servomotors and are designed for high torques and high performance. In order to realise several machining steps, the units are built with integrated water-cooled motor spindles and high- performance facing head technology. The machine has automatic tool changing systems on both sides for 12 or 20 tools (HSK A63 or HSK A100). Typical applications are OD and ID turning, facing, tapping, bevelling, threading, grooving, chamfering and boring, in particular for welding end preparation and manufacturing of cylinders, pipes and tubes.

three-layer blue polyethylene according to DIN 30670. Pipe and fitting surfaces are prepared by blasting and heating prior to the application of fusion bonded epoxy (to 150 microns), adhesive (to 100 microns), and extruded, heat-bonded polyethylene. The properties of the three-layer coating are based on the adhesion between the layers. This provides protection from impact and indentation, as well as corrosion protection. FT Pipeline Systems supplied pipes and pipe fittings to a variety of different projects in preparation for the London Olympics in 2012. Steel was chosen over alternative materials by a number of contractors due to the difficult ground issues prevalent in the East London area. Ranging from 80 to 1,200mm diameter, all the pipes and fittings supplied complied with DWI regulations and were coated with the three-layer PE, allowing them to be installed in brownfield sites. Projects included the infrastructure of the Olympic Park in Stratford, East London, the water mains replacement at Finsbury Park, and

STEEL water pipes have been the choice for many pipeline sites across the UK. Some of the benefits associated with steel include pressure ratings, no thrust blocks, longer lengths, flexibility, variety of end connections, and epoxy or cement mortar internal linings. However, the over-riding benefit to the water industry of steel pipes supplied by FT Pipeline Systems lies in the corrosion protection provided by the

Double head CNC end-working THE flexible end-working of tubes and pipes is crucial for the production process in the automotive, petrochemical (oil and gas), ship and offshore industries, and particularly in industrial domains involving technology. All components are aligned in order to realise high accuracy over the length. The end-working concept comprises a fixed workpiece and revolving tools.

the manufacturing of hydraulic cylinders and piston rods. Arla’s new EMXSC-2 is a CNC-controlled end- working machine for the double sided machining of workpieces with a maximum OD of 275mm and a maximum length of 2,500mm. The machine concept is based on a solid frame with two precise machining units including a concentric work-holding
