Seal in the Savings with CoreSeal

A High‑Performance, Cost‑Effective Insulation System for Refrigeration & Industrial Applications

SEAL IN THE SAVINGS WITH CORESEAL

CoreSeal is a fully engineered refrigeration and industrial pipework insulation system

Developed by TPM and Technotherm Ltd. - leading suppliers of high‐quality pre‐insulated pipe and specialists in advanced Foam‐in‐Place (FIP) technology. This combined approach delivers a robust, long‐lasting, and highly efficient insulation solution that reduces installation time, improves system performance, and lowers overall project costs. CoreSeal is ideal for refrigeration plants, food production facilities, industrial cooling systems, cold storage infrastructure, and any environment where thermal integrity and vapour control are critical.

Why Choose Our Pre-Insulated Pipes?

Our pre-insulated pipe systems are meticulously designed to ensure optimal thermal efficiency and long-lasting durability for heating, cooling, and industrial.

Superior Insulation

Our pipes minimise heat loss and maximise energy savings.

Durable Construction

Robust HDPE outer casing and corrosion-resistant inner pipes.

Easy Installation

Designed for quick simple installation, reducing downtime.

Long-Term Reliability

Prevents condensation and ensures longitivety in harsh environments.

Coreseal is built on two core components working together: factory‐produced pre‐insulated pipes and a bespoke FIP injection system applied to all joints, bends, and fittings.

Our Pre-Insulated Pipe:

Manufactured under strict quality‐controlled conditions.
Available in a full range of carrier pipe materials: carbon steel, stainless steel, copper, HDPE, and more.
Outer casings available in HDPE, Alu‐Zinc spiral, or aluminium spiral depending on project needs.
Engineered for strength - capable of withstanding heavy handling, lifting, and movement during construction stages.
Highly resistant to puncture and mechanical damage, protecting the insulation core during installation.
Custom insulation mixes and casing configurations can be designed to meet exact temperature and system requirements.

Foam‑in‑Place (FIP) Injection System

Integrates seamlessly with the pre‐insulated pipe - creating a continuous insulation envelope.
Provides full thermal coverage on joints, bends, fittings, valve stations, and cooler penetrations.
Eliminates air gaps and weak points that commonly cause thermal bridging and condensation.
Pre‐made casings and rapid foam injection dramatically reduce time spent on site.
Ensures consistent density, adhesion, and insulation quality throughout the system.

Key Benefits of CoreSeal

No Need for High‐Density Pipe Supports The structural strength of the pre‐insulated casing eliminates the requirement for expensive high‐density supports across long pipe runs. Reduces material costs and simplifies installation.

Significant Reduction in On‐Site Labour Pre‐insulated lengths and FIP jointing streamline installation. A typical 1,000m industrial refrigeration project can save approximately 320+ man‐hours. Faster installation means shorter shutdowns and reduced disruption.

Durability & Long‐Term Asset Protection Dinitrol anti‐corrosion coating applied to carbon steel pipework for maximum longevity. Foil wrap applied to stainless steel to prevent chlorine corrosion on the pipework. All joints sealed using silicone sealant and Fosters 95‐44 mastic to ensure long‐term airtight performance. Pre‐insulated pipes are extremely robust, difficult to puncture, and maintain their structural integrity even in demanding construction environments.

Improved Thermal Efficiency & Lower Operating Costs FIP injection guarantees complete cavity fill and eliminates voids. Reduces thermal losses and enhances refrigeration plant efficiency. Minimises the risk of condensation, frost build‐up, and corrosion under insulation (CUI). Better insulation performance = lower running costs and increased system reliability. The 3D model below demonstrates how our Pre-Insulated Pipe System integrates perfectly with our Foam-in-Place solution to deliver a continuous, high-performance insulation system.

Additional Support Services

To complement the CoreSeal System, we also provide:

Fully engineered pipe support brackets and stands (design, manufacture, supply).

High‐density pipe supports for valve stations and specialist conditions.

Insulated pipe penetration sleeves for walls, roofs, and cold rooms.

Insulated valve cap covers, colour‐coded to customer specifications - a durable alternative to Armourflex bonnets.

Comprehensive thermal imaging surveys at project completion to confirm full system performance and identify any areas requiring fine‐tuning.

Post‐injection integrity checks - we will open and examine random sections to verify complete foam fill and confirm that every cavity is fully sealed.

CoreSeal FIP Process Overview

Precision-Engineered Insulation from Start to Finish

The CoreSeal Foam-In-Place (FIP) system delivers a fully sealed, high-performance insulation solution designed for refrigeration and process pipework. Each stage of the installation process is carefully controlled to ensure maximum thermal efficiency, structural integrity, and long-term protection against moisture ingress and corrosion. From pipe preparation through to final inspection, the CoreSeal system creates a dense, uniform insulation barrier that eliminates voids, protects critical pipework, and provides a durable outer casing suitable for demanding industrial environments.

Step 1

Pipe Surface Preparation

Carbon steel: cleaned and coated with anticorrosion layer.

Stainless steel: cleaned and wrapped with foil vapour barrier.

Step 4

Vapour Sealing

Silicone sealant applied to all joints.

Fosters 95‐44 mastic applied on termination points.

Step 2

Casing Installation

Casings fitted and mechanically secured to ensure strong structural integrity.

Step 5

End Caps & Terminations

Steel end caps installed and sealed for long‐term protection.

Step 3

Foam Injection

High‐performance foam injected into the cavity, expanding to fill all voids.

Curing ensures a dense, uniform insulation structure.

Step 6

Final Inspection

Verification of full foam coverage. Vapour integrity checks.

Confirmation of protective coatings and overall system quality.

Built for Performance. Designed for Longevity.
