Very professional team, easy to talk to. We had some specific size requirements and they nailed it. The TP304 stainless tube with aluminum fins works like a charm for heat dissipation. Thumbs up!

We checked a few before installation — wall thickness consistent, roundness good. Welded in without problems.
