The stainless steel industrial fluid pipes supplied by GNEE have long service life and low maintenance cost. They have low failure rate and water leakage rate. They are hygienic and free of impurities. The inside of the pipe is smooth and scale-free, and the resistance to conveying liquid is low. They can withstand erosion at flow rates up to 30m/s.
