The heavy structural bed accommodates wall thicknesses from 3.0 up to 12.7 mm.<\/p>\n<p><strong>Q: What are the maximum overall dimensions and weight limits for packed bundles?<\/strong>\nA: Hexagonal bundles can span up to 1,100 mm in width and 1,000 mm in height. Square or rectangular packs reach up to 950 mm in width by 800 mm in height. Maximum tube length is 16 m, with bundle weights supported up to 13,000 kg.<\/p>\n<p><strong>Q: How does the system prevent surface damage on sensitive, coated, or high-finish pipes?<\/strong>\nA: Conveyor rolls and lateral guide arms are coated with vulcanized polyurethane or ultra-high-molecular-weight polyethylene (UHMW-PE). Infeed transfer relies on electro-permanent magnetic Chuck beams or servo-controlled lowering arms that eliminate free-fall drop impacts.<\/p>\n<p><strong>Q: Can the line run mixed production of round, square, and rectangular tubing?<\/strong>\nA: Yes. The PLC memory stores multiple recipe profiles. The V-bed forming geometry adjusts automatically via motor-driven positioning screws, switching from hexagonal nesting for round tubes to flat-bottom configurations for square and rectangular profiles without physical tooling teardown.<\/p>\n<hr \/>\n<h2 id=\"next-step\">System Sizing &amp; Project Consultation<\/h2>\n<p>Fhopepack custom-engineers complete tube bundle handling and strapping lines tailored to factory footprints and mill speeds:<\/p>\n<ol>\n<li><strong>Submit Facility Layout &amp; Product Mix:<\/strong> Send your mill layout, tube dimensions (OD, wall, lengths), bundle configurations, and mill line speeds to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive 48-Hour Technical Proposal:<\/strong> Our mechanical applications team will deliver a comprehensive proposal including cycle-time simulations, footprint dimensions, and equipment bill-of-materials within 48 hours.<\/li>\n<li><strong>Engineering Site Survey &amp; Interface Review:<\/strong> Our systems engineers evaluate existing run-out tables, bay crane clearances, and utility hookups to confirm seamless physical and electrical integration.<\/li>\n<\/ol>\n<hr \/>\n<h2 id=\"related-reading\">Related Reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-Steel-Tube-Packing-Line\/automatic-packing-line-for-steel-tube-bundle.html\">Automatic Packing Line for Steel Tube Bundle and Profile<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Automatic-Steel-Tube-Packing-Line\/Automatic-steel-pipe-bundle-packing-line.html\">Automatic Steel Pipe Bundling and Packing Line Solutions<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/steel-tube-packing-machine.html\">Heavy-Duty Automatic Steel Tube Strapping Systems<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/how-we-achieved-remote-commissioning-of-a-full-steel-coil-packing-line\/\">Field Commissioning Case Study: Slit Coil and Long-Bar Handling Systems<\/a><\/li>\n<\/ul>\n<hr \/>\n<h2 id=\"sources\">Sources &amp; References<\/h2>\n<ul>\n<li>Line Technical Architecture &amp; Operating Parameters: <a href=\"https:\/\/www.fhopepack.com\/Automatic-Steel-Tube-Packing-Line\/automatic-packing-line-for-steel-tube-bundle.html\">Fhopepack Tube &amp; Profile Bundling Systems<\/a><\/li>\n<li>Industrial Packaging Machine Safety: <a href=\"https:\/\/www.iso.org\/standard\/51528.html\">ISO 12100:2010 Safety of Machinery<\/a><\/li>\n<li>Specific Packaging Machine Guarding: <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014 Safety Requirements<\/a><\/li>\n<li>Video Demonstration &amp; Motion Reference: <a href=\"https:\/\/www.youtube.com\/watch?v=placeholder_tube_bundling\">Fhopepack Tube Handling Operations on YouTube<\/a><\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-05<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary A high-capacity steel tube bundle packing line automates the end-of-line cycle from the mill run-out table to finished storage.
