Product Overview
The HF‑HPM‑1A1B‑PipeInsulation is a high‑pressure PU foaming system for annular pipeline insulation, delivering rigid, void‑free foam with accurate proportioning and eco‑friendly cleaning.
This high‑pressure polyurethane foaming machine is specially designed for thermal insulation of pipelines used in HVAC systems, water supply and drainage, chemical processing, and thermal energy transportation. It supports both direct‑burial pipelines and prefabricated insulation layer pouring, meeting the core requirements of sealed insulation, full filling without gaps, and long‑term corrosion protection. The system features independent temperature‑controlled tanks (100L/150L optional) with circulation stirring, a high‑speed mixing head (8000‑14000 r/min) operating at 10‑18 MPa pressure, and a PLC‑based control system with multi‑formula storage. The annular pouring design ensures full circumferential filling with no voids, while the rigid foam structure bonds firmly to the pipe surface, enhancing the integrity and durability of the insulation layer. The machine is designed for convenient mobility, suitable for both on‑site pipeline construction and factory‑based prefabrication. Its automatic air purge cleaning system is solvent‑free and environmentally friendly, minimizing downtime and chemical waste. With stable and accurate proportioning (A:B = 100:100‑130), the machine delivers uniform insulation layer thickness and high construction consistency across long production runs.
Production Workflow
Material Preparation
Load polyol and isocyanate into temperature‑controlled tanks (100L or 150L), set to 20‑45°C with circulation stirring.
Recipe Selection & Ratio Setting
Choose stored formula on PLC touch screen; set A:B ratio (100:100‑130) and pouring rate (80‑1500 g/s) per pipe diameter and insulation thickness.
Annular High‑Pressure Pouring
Position mixing head around pipe; inject PU foam at 10‑18 MPa and 8000‑14000 r/min, ensuring full circumferential fill with no gaps.
Curing & Air Purge Cleaning
Allow foam to cure and bond to pipe surface; trigger automatic air purge cleaning to prepare head for next pour without solvents.
