Liners and Resins
In the pipe renovation industry, resins and liners are critical components used with UV curing equipment to repair and reinforce aging or damaged pipelines. This innovative technology ensures efficient, durable, and environmentally friendly solutions for a variety of applications, from residential to industrial settings.
Introduction to Liners & Resins
In the pipe renovation industry, resins and liners are critical components used with UV curing equipment to repair and reinforce aging or damaged pipelines. This innovative technology ensures efficient, durable, and environmentally friendly solutions for a variety of applications, from residential to industrial settings.
Types of Liners
There are various types of liners designed for different curing methods, such as UV or all cure methods. Felt liners are available in two options: one for UV curing, suitable for up to 12”/300mm, and another for all cure methods, which can accommodate sizes up to 110”/2750mm.
These liners offer multiple options to fit a range of job requirements. Invertible fiberglass and hybrid liners provide better light penetration and also offer several options to meet different needs. GFRP liners, which start at 6” and up, are pulled into place using a winch rather than an air compressor. Air is then used to inflate the liner once it is properly positioned.
Types of Resins
There is a variety of UV LED resins compatible with Sewertronics equipment. Compatibility of UV LED resins with Sewertronics equipment resides in the existence of initiators that react in the presence of our UV radiation wavelength of 400 nm. The liner and resin selected also needs to be compatible with one another along with the system you are using.
Different types of UV LED resins exist currently in the market, each of which presents certain particularities regarding curing speeds, bonding to the pipe, chemical behaviour and others.
The most common resins used with felt liners are VE (Vynil Ester) and derivatives such as MA (methacrylate) always styrene-free. An unsaturated polyester resin with styrene (UP) is typically used for GRP liners.
UV Curing Technology
UV curing technology plays a vital role in the pipe renovation process.
The key benefits include:
Speed: UV curing significantly reduces curing times compared to traditional methods, allowing for faster project completion and minimal disruption.
Efficiency: The UV light initiates an exothermic reaction that cures the epoxy resin evenly and thoroughly, ensuring a high-quality, durable repair.
Safety: UV curing produces less heat and no harmful emissions, making it a safer option for both workers and the environment.
Precision: The controlled application of UV light allows for precise curing, ensuring optimal performance of the resin and liner.
Epoxy resins and liners, combined with UV curing technology, provide a powerful solution for the pipe renovation industry. These materials and methods ensure efficient, durable, and eco-friendly repairs, extending the lifespan of pipelines and enhancing their performance. Whether dealing with residential plumbing or large-scale industrial pipelines, the right combination of epoxy resin and liner can meet the specific demands of any project.
