Size to the heaviest regular course, not to finished vessel mass (same rule as API 650 sizing).<\/li>\n<li><strong>Minimum diameter is a real limit.<\/strong> HGZ-50\u2019s confirmed band starts at 800 mm. A 500 mm pipe is an HGZ-10 conversation (400\u20133,500 mm), not a \u201csmaller 50 t machine.\u201d<\/li>\n<li><strong>Self-aligning vs adjustable is a changeover choice, not a diameter choice.<\/strong> Use the existing adjustable-vs-self-aligning cluster for that decision.
