What is the average lead time for production?

Lead times vary by season: Peak season takes 1-3 months, while off-season delivery is within 15 workdays to one month.

Is customization available for the pipe structure and dimensions?

Yes, we offer turnkey projects with customizable pipe structures (Steel Pipe-Polyurethane Foam-HDPE Casing), foaming thickness (30-100mm), and pipe diameters (100-2200mm).

What is the principle behind the foaming process?

The system uses a High-Pressure Air Type principle to inject polyurethane foaming material into the casing for efficient insulation layer creation.
