Flangeseal: An Excellent Option for Protecting Flanges from Corrosion

 Flangeseal: An Excellent Option for Protecting Flanges from Corrosion

Flanges play a crucial role in connecting pipes and ensuring the integrity of industrial systems. However, these vital components are susceptible to corrosion, which can compromise their performance and lead to costly repairs. To prevent this issue, a reliable solution is needed, and Flangeseal emerges as an excellent option for protecting flanges from corrosion while offering easy installation.

One of the key advantages of Flangeseal is its backing with integrated fiberglass reinforcement. This feature gives the product toughness and long-lasting durability, allowing it to withstand harsh environments and demanding conditions. Additionally, the high recovery capacity of Flangeseal, combined with its impressive 65% shrinkage ratio, enables it to conform to high transitions smoothly. This versatility reduces inventory and logistics costs, making it a cost-effective choice for protecting flanges.

The mechanical resistance backing of Flangeseal is another noteworthy feature. It is designed to resist abrasion, impact, and penetration, providing reliable protection for flanges against various forms of damage. Moreover, the sealant used in Flangeseal is specially formulated to ensure a strong bond and a tight seal to virtually any substrate. This ensures that the seal remains intact, even when exposed to a wide range of temperatures, maintaining its elasticity and sealing characteristics over time.

One of the standout features of Flangeseal is its self-healing effect. The sealing adhesive has the ability to automatically flow and repair minor mechanical damages. This capability not only enhances the longevity of the product but also saves money by reducing the need for frequent maintenance or replacement. Additionally, Flangeseal does not require a primer, eliminating the need for drying time and making the application process quick and easy.

Installation of Flangeseal is made even more convenient by its zipper closure system. This system simplifies and accelerates the installation process, ensuring a secure fit around the flanges. Moreover, Flangeseal does not require any special equipment for installation, making it accessible to a wide range of users. This not only saves time but also keeps installation costs low.

The excellent performance of Flangeseal is further supported by its impressive properties. The bursting strength of the backing, tested according to DIN 30672, is measured at 3500 N, demonstrating its ability to withstand significant pressure. The adhesive's softening point, tested per ASTM E-28, is 92°C (198°F), indicating its high-temperature resistance. Additionally, the shear strength and peel strength of the adhesive, tested according to EN12068, are 8 N/cm² and 9 N/cm, respectively, confirming its strong bonding capabilities.

Flangeseal is a heat shrinkable corrosion protection sleeve specifically developed for installation on flanges or mechanical couplings that are already in place. It consists of two layers: a visco-elastic sealant and a fiberglass-reinforced, radiation cross-linked, polyethylene backing. The product comes in pre-cut sleeves with a zipper closure system, allowing for fast and simple installation. Additionally, each kit includes a corrugated cardboard sheet to keep the flange nuts and bolts clean, facilitating easy re-entry and disassembly when necessary.

The installation process of Flangeseal is straightforward. After cleaning and preparing the pipe surface and flange, the corrugated cardboard sheet is wrapped around the flange to be sealed. The heat-shrinkable sleeve is then positioned centrally over the flange and closed using the zipper closure. As the sleeve is heated above 125°C (257°F), it shrinks tightly around the substrate. During the recovery process, the adhesive softens and flows, forming a tight bond. The bond strength further develops during cool down and remains fully intact upon completion of the installation process.
