In the spotlight: Ecoseal
From time to time, pipe systems may suffer from leaks or damage such as corrosion. This is an unfortunate side-effect of age, time, movement and disruptive ground works. The priority in this situation is to seal the pipe joints as quickly and efficiently as possible to prevent any disruption to the supply chain.
Ecoseal was originally developed in the 1990s as an alternative to anaerobic leak sealing solutions and encapsulant products. Things have changed since then, but at the time, the anaerobic products available were acid-based and relied upon contact between the product and the metal pipes for the chemical reaction to take place.
Although this indicated that the repair process had begun, it also caused toxic fumes to be released leading to health problems for the engineers and technicians that used them. This problem was compounded by the fact the repairs took place in small, enclosed and poorly ventilated spaces.
Enter Ecoseal, a two-part polyurethane resin (not an anaerobic solution). As a two-part resin, the chemical reaction takes place in the static mixer when the two parts meet and combine to form the resin. This can then be injected into a range of leaking joints in need of repair or maintenance.
Ecoseal remains one of our best-selling products to date and has stood the test of time. It is approved to Gas Industry Standard (GIS) LC25, which is designed for external sealant injection systems for joint repair on metallic distribution pipes operating at pressures of 2 bar or less.
Overtime, Ecoseal has developed into the product it is today. There are now three varieties, each of which is a different viscosity, so it can be applied to a range of leaking joints.
- Ecoseal Red (Thick) has the viscosity of molasses once the mixing process begins. This enables the product to flow slowly ensuring a complete seal when used on mechanical joints with large internal cavities to fill such as screwed gland and bolted variations.
- Ecoseal Yellow (Thin) has a lower viscosity than Ecoseal Red and is comparable to an emulsion paint when the mixing process begins. This allows the product to flow more freely in tight spaces within the joint.
- Ecoseal Green is our Ultra-Thin variant and has the viscosity of water. Green Ecoseal is ideal for lead yarn joints or similar applications where a very low viscosity liquid is required to ‘search’ for the smallest of leak paths.
Features and benefits:
There are multiple benefits to using Ecoseal over anaerobic products, including the fact that Ecoseal creates an elastic-like seal around the joint instantly without the need for steel clamps or fabric encapsulation kits. It is environmentally friendly due to the chemicals used, it will wash off clothes if spilt and the user will suffer no harmful side-effects after using Ecoseal.
Once cured, Ecoseal is waterproof and flexible allowing for pipe movement, which lengthens the life of pipes in areas with excessive ground vibration or movement. It is designed to last for up to 50 years and is easily applied when injected correctly.
