DIGITALISATION OF THE DANISH DISTRICT HEATING SECTOR
CASE CATALOGUE 2023
“THE WELDMASTER PORTAL IMEETS OUR HIGH EXPECTATIONS FOR EACH JOINT INSTALLATION. AS AN ISO 55001 CERTIFIED COMPANY, IT’S IMPORTANT TO US TO MAINTAIN AND EXTEND THE LONG OPERATIONAL LIFE OF OUR DISTRIBUTION SYSTEM, AS THIS REDUCES OUR MAINTENANCE COSTS AND LOWERS HEATING COSTS FOR THE CONSUMER.”
TOMMY H. HERMANN, MAINTENANCE MANAGER, TVIS
Solution The welding process has become as automated as possible at TVIS thanks to the LOGSTOR WeldMaster portal and its traceable documentation on all fitted joints. A 2D barcode on the weld joint is scanned using a PDA or a mobile phone. The correct welding machine settings for the specific joint are then automatically transferred to Weld- Master. The PDA or the mobile phone notifies the operator via LOG- STOR Connect whether the joint installation is approved or not approved.
or their mobile phone that the following have been com- pleted during the joint installation: checks and inspection of the alarm system, leakage tests, test of foam moulding, and visual check of the final joint installation.
LOGSTOR Connect files image documentation of each joint installation and each weld is automatically numbered.
Results Weld data is automatically uploaded, and TVIS, the contrac- tor and the advisor, can access the documentation once it has been registered with a licence. This means that docu- mentation for each joint installation can always be retrieved, and that TVIS can ensure each joint in their new district heating distribution network has been installed and docu- mented correctly. TVIS also avoids the additional expense of repairing poorly installed joints during the lifetime of the distribution network.
The joint is re-welded if it is not approved, and the difference between the approved and not approved weld is registered.
Operators then use Logstor Connect to certify via the PDA

INFORMATION
Challenge TVIS, the district heating company located on the east coast of Jutland, wanted to check, manage and digitalise its monitoring of weldings in its pipe system before the pipes are covered to ensure that the weld joint has been installed
correctly. The company also wanted to file documentation of correct installation of weld joints in the transmission system. The objective was to achieve a longer life span for pipes without unnecessary repairs on bad welds.
