High-Pressure PU Foaming Machine for Pipeline Thermal Insulation

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.

The HF-HPM-1A1B-PipeInsulation is a high-pressure PU dispensing reference for configured pipe-insulation applications. Material conditioning, circulation, metering, mixing-head design and pouring fixtures are selected for the formulation, pipe geometry and insulation thickness. Mixing pressure and metering output are confirmed on the quotation and equipment drawing; the source mechanical-head rotational speed is not treated as a verified high-pressure mixing-head parameter. Cavity filling, foam quality, adhesion and insulation performance require representative trials and agreed finished-part inspection.

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 the configured dispensing head and pouring fixture for the pipe geometry. Confirm pressure, output, filling pattern and material reaction through representative trials.

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.

Precision parameters for reliable pipeline foam insulation

Technical Specifications

Specifications are based on standard configurations at ambient conditions. Tank sizes and pouring rates can be customized for specific pipe diameters and insulation requirements.

Why Choose Our Pipeline Insulation Foaming System

Key Advantages

Six engineering benefits that ensure void‑free, uniform, and durable polyurethane insulation for pipelines in HVAC, water, chemical, and thermal applications.

Configured Annular Pouring

Pouring fixtures and dispensing settings are selected for the pipe geometry; finished-foam filling and adhesion are verified by trials and inspection.

High‑Speed High‑Pressure Mixing

Mixing head operates at 8000‑14000 r/min and 10‑18 MPa, producing uniform rigid foam with fine cell structure and strong adhesion to pipe surfaces.

Stable & Accurate Proportioning

Closed‑loop metering with ≤±0.3% accuracy ensures consistent A:B ratio (100:100‑130), resulting in uniform insulation thickness and high construction quality.

Solvent‑Free Air Purge Cleaning

Automatic air purge cleaning system eliminates the need for chemical solvents, reducing environmental impact, simplifying maintenance, and lowering operating costs.

Versatile for Site & Factory Use

Compact and mobile design supports both on‑site pipeline construction and factory‑based prefabrication, adapting to different project requirements with ease.

Intelligent PLC Control

Touch screen with multi‑formula storage enables quick recipe recall and one‑click switching, with full data traceability for batch quality control.

Frequently Asked Questions

What pipe diameters can this machine accommodate?
The machine supports a wide range of pipe diameters through adjustable pouring rate (80‑1500 g/s) and interchangeable mold/positioning fixtures. For very large or small diameters, custom tooling can be provided to ensure optimal annular filling.
How does the machine ensure uniform insulation layer thickness?
Metering accuracy, pressure and mixing-head configuration must be confirmed for the selected model and formulation. The source brief combines a high-pressure value with a mechanical-head speed; these should not be treated as one verified configuration until the equipment drawing is checked. Wall thickness is validated through tooling, dispensing trials and finished-part inspection.
Is the machine suitable for on‑site pipeline construction?
Yes, the machine is designed with mobility in mind. Its compact footprint and wheels allow easy transport and positioning at construction sites. It can be powered from standard site electrical supplies and operated directly on the trench or pipe rack.
How does the air purge cleaning system work without solvents?
After each pour, the system uses high‑pressure air to purge residual material from the mixing head and nozzle. This mechanical cleaning method is both environmentally friendly and cost‑effective, eliminating the need for solvent storage and disposal, while reducing maintenance time.
Can this machine handle both rigid and flexible foam formulations?
The HF‑HPM‑1A1B‑PipeInsulation is primarily designed for rigid polyurethane foam systems used in thermal insulation. However, with appropriate recipe adjustments and ratio settings (100:100‑130), it can accommodate certain semi‑rigid formulations. We recommend consulting our engineering team for specific material compatibility.
