Only 3.5 kilometers of piping will be buried - the rest will be above ground. As Gothenburg is right on the coast, the air has high salt content, the second highest (C5) corrosion class. For this reason Annebergs Bygg & Anläggning and Infra Supply have chosen SSAB's concrete-encased pipes with PE coating.
“SSAB is the only one who offers this solution and we are very proud to be able to implement it here in Gothenburg. It also provides an extremely long life, which we value highly,” says Kristian Vevang.
An S355 grade steel is used in the project, which has higher strength than standard, and this allows the project to reduce some of its costs.
“Thanks to the strength, the pipes can hang freely over quite long distances and this means that we need less pipe support and fewer concrete foundations, which is cost-saving for us.”
The right quantities at the right time
Planning for the entire project is carried out month-by-month. Therefore, pipe orders from SSAB are also made on a monthly basis. In order for the project to be on schedule, SSAB needs to deliver the right amount of pipes at the right time.
“SSAB's delivery reliability means that we neither receive over nor under the consignment. That, together with their capacity and willingness to do what’s best for the project, makes them unique. They are very responsive to changes and are on their toes throughout the course of the project. They are one of the few companies that can live up to our requirements,” says Kristian Vevang.
“What I appreciate most about SSAB is the security – knowing that I have a solid partner. They stand by all their guarantees and commitments. We are very satisfied with the cooperation with them and I know that I will have a long relationship with SSAB in many projects to come.”
