Step-by-Step Guide to Installing Aerogel Blankets for Pipeline Insulation in Harsh Environments

Back when I first started shipping aerogel blankets from our Hebei setup, a lot of clients—especially those in petrochem pipelines—would ping me with the same question: "How do we install this stuff without messing up?" It's fair; aerogel's thin and flexible, but get the fit wrong, and you lose that ultra-low thermal edge. Over the years, we've honed a straightforward process from factory tests to on-site jobs in places like Gujarat's refineries, where temps swing from scorching days to chilly nights. Here's how we do it, step by step, to lock in performance and save you headaches.

First off, prep is everything. Unroll the blanket in a clean, dry spot—avoid dusty yards if you can. Measure your pipe: add 10-15% overlap for seams to prevent bridging. We use blankets cut to 1m x 1.5m rolls, but trim with a sharp utility knife on a flat board. Pro tip: mark with chalk, not pen, to keep it clean. Check the surface too—wipe off rust or oil, per ISO 12944 standards for corrosion protection. In one Australian solar project we supplied, skipping this led to a redo; don't learn the hard way.

Next, wrapping: Start at one end, align the blanket snug but not stretched—aerogel hates compression over 10%. For straight pipes, spiral wrap with 50mm overlap; on bends, fan out the material to avoid wrinkles. Secure with stainless steel bands every 300mm, or high-temp adhesive tape if it's under 200°C. We've seen great results with 3M's VHB tape in lab tests, holding firm without residue. If it's a high-vibe setup like offshore rigs, add wire ties for extra grip.

Layering comes in if you need thicker insulation—stack two blankets with staggered seams to block cold spots. In a European passive house retrofit we heard about, this doubled efficiency without bulking up. Finally, test: Use an IR camera to scan for hot spots post-install. Aim for under 5% variance in surface temp, as per ASTM C1045 guidelines. If gaps show, patch with aerogel powder filler.

This method's cut install time by 20% in our trials, and clients report 30-40% less energy loss versus traditional wool. Got a tricky pipe run? Shoot us details—we've tweaked for everything from subzero storage tanks to desert lines. What's your toughest install challenge been?
