Automatic Polyurethane Spray HDPE PE Wrapping Steel Pipe Thermal Insulation Machine

Automatic Polyurethane Spray HDPE PE Wrapping Steel Pipe Thermal Insulation Machine
Product Overview

Our professional PUR spray HDPE wrapping steel pipe thermal insulation production line is independently engineered by Huashida for manufacturing large-diameter pre-insulated steel pipes ranging from 508mm to 1620mm. This all-in-one polyurethane foam insulation pipe machine combines three core functional modules: steel pipe external shot blasting derusting unit, continuous polyurethane spray foaming system and HDPE strip wrapping production section for complete buried district heating pipe fabrication.

As premium patented thermal insulation pipe manufacturing equipment, the whole set owns multiple national utility patents, third-party Level 5 technology certification and Shandong Provincial First Set of Technical Equipment accreditation, complying with top domestic industrial standards for large diameter pre-insulated pipeline production.

Adopting continuous automatic PUR spray technology, this fully PLC-controlled pre-insulated steel pipe production line boosts overall output while cutting raw material and power wastage. It forms stable three-layer trinity composite structure (steel pipe + PU foam insulation + HDPE outer jacket) with high closed-cell foam rate and low water absorption. Finished eco-friendly low-carbon polyurethane insulated steel pipes hold consistent insulation performance for underground heating pipeline projects.
