Neeka Tubes has built a strong reputation as a reliable manufacturer of Stainless Steel Impulse Tubing. We serve some of the most demanding industries in the world. This tubing is designed for high-pressure and high-temperature situations ensuring that fluids and gases are transported accurately. The Seamless Construction ensures that the inside surface and walls are smooth and strong which lowers the risk of leaks and pressure drops in sensitive systems. It is an important part of control and instrumentation systems that helps them work smoothly and well.
Our stainless steel impulse tubing comes in different sizes, diameters, and wall thicknesses. It is made from strong and long-lasting stainless steel. Tubing is available in both seamless and welded types. It meets the standards set by ASTM, ASME and ISO. It is checked for pressure, temperature strength, and overall strength, which makes it perfect for important industrial uses.
