Supplying and laying of stainless steel (SS) pipe of size 15/16mm OD is designed for high- pressure misting systems up to suitable depth below the ground level with trenching and backfilling, capable of handling operational pressures between 40 to 80 bar. Made from durable, corrosion-resistant stainless steel, this seamless pipe ensures reliable performance in demanding environments, such as outdoor cooling systems, greenhouses, and industrial misting applications. Its polished exterior prevents rust and scaling, while the precision-engineered wall thickness guarantees strength and safety under high pressure. Compatible with various high-pressure fittings, this pipe meets international standards like ASTM A269/A213, making it ideal for both residential and commercial misting installations, including supplying and fixing of all other suitable accessories for connection between steel pipe and nylon pipe, cutting, welding, testing & commissioning etc. as required. Road Cutting and repairing of the same for laying of pipe shall be done by the agency and nothing shall be paid extra for this.

Providing &Fixing of 19/mm suitable size high-pressure pipe Hyraulic Pipe 1/4 " R2 (on the exiting pole up to required height) is designed for applications requiring a pressure rating between 40 to 80 bar, making it ideal for use in misting systems, industrial automation, and other high- pressure environments. Constructed from durable, lightweight nylon, this pipe offers excellent flexibility, resistance to abrasion, and chemical stability, ensuring long-lasting performance under demanding conditions. Its smooth inner surface minimizes friction losses, promoting efficient fluid flow, while its tough outer layer withstands environmental factors like UV exposure and impact. Including supplying and fixing of all other suitable accessories for inter connection between nylon pipe misting nozzle, testing & commissioning etc. as required.
