Enhanced data collection capabilities The McElroy DataLogger 6 offers expanded data collection capabilities and new features with a free software update that is now available. This pressure along with bead size recognised by the operator is the key to the correct heat soak.

Also included is the ability to retrieve joint reports that are stored in the McElroy Vault, regardless of which specific DataLogger device uploaded them to the account. This gives users the flexibility to keep one device on the machine doing the work and a second to capture as-built notes, pictures and coordinates when

Users have the ability to zoom into multiple portions of the graph, which makes it easier to confirm that the fusion was carried out properly during each stage of the process. The DataLogger 6 can now capture weather conditions in the field, which can affect the fusion process. The operator can input ambient temperature, pipe temperatures and basic weather conditions.

Version 1.09 includes built-in options to record fusion information from manually operated machines. Pipe fusion operators can easily gather important key elements that add to tracking and traceability efforts, including operator, equipment, material, location, pictures, notes and fusion standards. A new FusionGuide display makes it easier to interpret drag pressure.

Galfan in multi-year real-life corrosion test A real-life corrosion test has been conducted, in which SSAB’s Galfan out- performed competing coating materials in terms of its ability to resist corrosion. The test result showed that Galfan is up to 3.8 times more resistant to corrosion compared to other tested zinc based coatings. The test was conducted by the French Corrosion Institute in collaboration with Swerema KIMAB. materials resist corrosion,” said Thomas Pettersson at SSAB. “In the test – which covers a period of five and eight years – we were able confirm that Galfan was 2.8 times better than zinc alone and no less than 3.8 times better than zinc- magnesium.”

Atmospheric corrosivity is measured in different categories. In theNordic region, typical categories are C2 (urban and rural areas) and C3 (marine environment). At the marine environment testing grounds in Bohus-Malmön (C3), Sweden, test

panels have been outside for many years to clarify how different zinc-based coatings withstand weather in real-life conditions. The results differ from laboratory salt- spray tests, and the real-life tests give Galfan ZA 255 a victory. Galfan is a zinc-based coating used in a variety of segments and on different steel grades to extend the useful life of steel parts. Alternatively, traditional zinc coating can be replaced with a thinner Galfan coating, which offers better welding and forming properties.
