Tubes run out on a roller table, a chain deck moves them sideways, and a yellow forming station gathers them layer by layer into a tight hexagonal bundle ready for strapping.

61 tubes for 5 per side in the worked example.<\/p>\n<p>Q: Can it make square bundles?\nA: Yes. We set the former for hexagonal, square or round bundles per your yard.<\/p>\n<p>Q: Can you build this configuration?\nA: Yes. We build equivalent tube bundle forming lines matched to your mill speed, bundle shape and strapping.<\/p>\n<p>Q: What comes after forming?\nA: The formed bundle goes on to strapping, then to the yard.<\/p>\n<p>Q: Which standards apply?\nA: For CE markets, ISO 12100 and EN 415-10.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We match a tube bundle forming line in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with tube sizes, lengths, tubes per bundle and mill speed, to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong> with the machine data and layout.<\/li>\n<li><strong>Book a site survey<\/strong> so we confirm the mill run-out layout.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-steel-pipe-bundling-and-strapping-machine\/\">Steel Tube Bundle Strapping with a Travelling Head<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/how-to-steel-pipe-bundle-strapping-with-timber-blocker-insert\/\">Steel Tube Bundle Strapping with Timber Blocks<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/technical-breakdown-32mm-heavy-duty-steel-tube-bundle-strapping-machine-with-buckle\/\">Steel Tube Bundle Strapping Machine with Seal Joint<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Steel-tube-strapping-machine\/\">Steel tube strapping machines<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Machine content: FHOPE engineering team, 2026-10-10<\/li>\n<li>Clip: <a href=\"https:\/\/www.youtube.com\/watch?v=Yjt3lNZYKzc\">the video on YouTube<\/a><\/li>\n<li>Tubes per bundle: our worked example, illustrative values<\/li>\n<li>Standards scope: ISO 12100:2010; <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<li>Proposal timing: approved house CTA (proposal within 48 hours)<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-10<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary This clip shows a steel tube bundle forming line at the end of a tube mill.
