EEW to supply 18 kilometers of SS pipes to Qatar using Outokumpu plates

It is reported that German pipe manufacturer Erndtebrücker Eisenwerk and Outokumpu have joined forces to supply 18 kilometer of LNG pipe for a dock loading facility Qatar Gas Berth 6 in Qatar Gas project. The delivery of the Qatar Gas Berth 6 pipes is scheduled for completion by mid summer of 2008.

Berth 6 is a new docking facility at Ras Laffan. To do its share of loading the Port’s projected 1,120,000 cubic meters of LNG per year, Berth 6 needs 18 kilometers of pipe running in several parallel lines between the storage tanks and loading points.

To manufacture the pipes at its Erndtebrück plant in Germany, EEW takes more than 4,600 tonnes of Outokumpu plate of grade 1.4301/1.4307 (304/304L) and 12.7mm thick plates. Outokumpu can produce this plate thickness both using the coil process and at its plate mills. In this case, EEW reaps benefit in production welding the pipes mainly from coil process plate, while producing a small volume of the pipes from quarto plates.

Pipe dimensions
1. 914.4mm x 12.7mm
2. 863.6mm x 7.92mm
3. 711.2mm x 12.7mm from quarto plate
4. 762mm x 12.7mm from quarto plate
18 kilometers of pipe, close to 16 kilometers from one size 914.4mm x 12.7mm

Pipe plate materials
1. 4591 tonnes of grade 1.4301/1.4307 (304/304L) CPP, 12.7mm thick
2. 42 tonnes of quarto plates of the same grade and thickness, 2.2m and 2.36m wide
Total 4633 tonnes

Mr James Heather sales director of EEW said “With Outokumpu, we have one partner for both CPP and quarto plates. We have been very successful together in subsea pipelines.”

Erndtebrücker Eisenwerk Group is a major producer of carbon steel SAW pipes and is the world’s largest producer of heavy wall large-diameter stainless steel SAW pipes.
