REFRACTEC ENGINEERING PRIVATE LIMITED 
Precision Guniting for Demanding Refractory Needs
Refractec Engineering Private Limited specializes in castable lining by guniting, a highly efficient and reliable method of applying refractory materials in areas that are difficult to reach or have irregular surfaces. This technique is especially ideal for applications requiring rapid installation, minimum downtime, and enhanced mechanical strength. Guniting, also known as shotcreting, is a dry or semi-wet process in which refractory material is pneumatically conveyed and sprayed onto the target surface under high pressure.
Guniting is widely used in boilers, furnaces, chimneys, ducts, and large refractory zones where manual brickwork or casting is impractical. With its ability to form a continuous lining over complex geometries, the guniting method ensures consistent coverage without cold joints, even in high-wear or high-abrasion zones. This makes it particularly suitable for industries such as steel, cement, petrochemical, and power generation.
Advanced Guniting Equipment and Expertise
At Refractec Engineering Private Limited, we utilize state-of-the-art guniting machines capable of delivering precise material flow and controlled application rates. Our experienced nozzlemen are trained to maintain optimal distance, pressure, and angle to achieve a dense, uniform, and well-adhered lining. The process is fast, efficient, and ideal for emergency repairs or large-scale new installations.
Superior Bonding and Structural Integrity
Castable guniting ensures excellent mechanical bonding with the substrate and offers a dense, high-strength refractory surface. The absence of formwork allows for faster work cycles and easier access to hard-to-reach areas. Moreover, with reduced rebound loss and high compaction during spraying, the finished lining is free from porosity and well-suited for high thermal load conditions.
Flexible Material Selection for Versatile Applications
We offer a wide range of gunning-grade refractory castables—ranging from dense and abrasion-resistant formulations to lightweight insulating varieties. Each mix is chosen based on the operating environment, ensuring resistance to thermal shocks, slag attack, chemical corrosion, or high-temperature abrasion. The versatility of this method ensures long-term reliability and enhanced performance.
Guniting delivers rapid, seamless, and high-strength refractory linings for demanding industrial environments.
Our guniting technique ensures even layering on complex and vertical surfaces without the need for formwork. This not only speeds up the application but also reduces drying time, making it ideal for emergency repairs or fast-track shutdown projects.
Our guniting solutions bring a perfect blend of speed and precision, offering rapid application and long-term performance, especially in hard-to-reach and high-wear zones where precision matters most.
