🔥 Pipe insulation · Foaming molding · Seamless fitting
Our pipe insulation polyurethane injection machine is suitable for injecting PU foam into the pre-set outer protective pipe to achieve an integrated foaming solution with high-strength bonding and excellent thermal insulation performance.

⚙️ Equipment advantages:
✅ Two-component high-pressure foaming system, uniform mixing
✅ Supports multi-nozzle/multi-diameter size adjustment
✅ Process parameters such as ratio, injection volume, temperature, etc. can be set
✅ Suitable for PE, HDPE, spiral steel pipe, straight seam steel pipe and other sheaths
✅ The insulation core layer is firmly bonded to the sheath and is not easy to fall off

📍 Widely used: regional heating, oil and gas transportation, industrial thermal systems, hot and cold water insulation pipes, etc.
