System solutions for manufacturing large diameter pipelines

Pipelines connect the world – produced with system solutions from Schuler for large pipe manufacturing. They cover long distances: through unforgiving landscapes, hostile weather conditions and the most extreme environments. And they transport the things needed for living in today’s world: crude oil and natural gas, petrochemicals as well as drinking water. The global demand of large diameter pipes for transport pipelines is growing. Harsh environmental conditions and remote on-shore and off-shore locations are imposing demanding requirements on future pipeline projects. Low temperatures and high external pressures in deep water impose enormous strain on the pipes. At the same time, there is a trend towards higher internal pressures for greater transport capacity. NORTON, an abrasives manufacturer and leader in metal fabrication abrasive products for over 125 years, has introduced two new Norton Quick Trim Flap Discs for the metal fabricating industry. The SG Blaze ® R980P and TwinStar Quick Trim Flap Discs feature a new flexible, easily-trimmed plastic back plate, allowing full use of the flaps. The plastic backing can be easily trimmed back to expose the flaps for extended product life. This reduces materials costs by allowing 100 per cent of the abrasive material to be consumed. The Quick Trim Norton SG Blaze R980P Type 27 flap discs feature the latest-generation ceramic alumina abrasive grain and an improved supersize grinding aid to provide 50-200 per cent longer life than any flap disc on

Schuler presents system solutions for both longitudinally welded as well as large diameter spiral welded pipes. When it comes to manufacturing longitudinally welded large pipes, Schuler’s hydraulic presses apply two different methods: U-canning presses and O-presses find their use in system solutions for the UOE process, C-presses and J step forming presses offer system solutions for the step forming process. Schuler designs and implements turnkey production plants to manufacture large diameter spiral welded pipes. Schuler spiral pipe welding plants are designed in two different variations: In the online process, pipe forming is directly followed by submerged arc welding; whereas in the offline process it is followed by tack welding. Then, on stainless steel, cobalt, chrome, Inconel, titanium and other hard-to-grind materials that is currently available on the market. Blaze R980P Quick Trim flap discs offer the highest productivity and lowest total grinding cost. The advanced supersize grinding lubricant also provides faster and cooler cutting for improved part finish and integrity. Durable, Y-weight polyester flaps significantly improve product life, grain retention and fray resistance. Discs in 4 1 / 2 ", 5" and 7" inch sizes are also available with 5 / 8 "-11 hubs for quick disc changes and less downtime. Norton Quick Trim TwinStar Type 27 flap discs are engineered for light stock removal, blending and finishing all in one application. They offer excellent performance and efficiencies on mild

separate welding stands, the submerged arc welding is performed. In addition, Schuler offers manufacturing solutions for the production of lined pipes used for the transport of aggressive or sensitive liquids. Schuler supplies machines, production lines, dies, process know-how and services for the entire metal-working industry. Its clients include car manufacturers and their suppliers, as well as companies in the forging, household equipment and electrical industry. The company employs around 5,200 people and is represented by its own facilities and sales offices in forty nations around the world.

Higher-performance abrasive flaps are mounted on the new, easy-to-trim plastic back plate for full use of each flap.
