Raw Materials
The SS 316H billets are chosen due to their high resistance to corrosion and the high temperature.
SS 316H Seamless Pipes are a premium product of Silver Tubes that is intended to suit the demands of various industries such as petrochemical, oil and gas, automobile, hydrocarbon, paper, sugar mills and boiler manufacturing. The pipes are made out of one piece of raw material, which makes them seamlessly constructed without any welding. The shape of the pipe is created by using a precise die that stipulates the inner and outer diameter and the pipe is cut to the size that the client requires. The lack of it makes it unnecessary to employ any welding repair, thereby preventing the necessity of the welding integrity test or further heat treatment, which makes 316H seamless pipes very dependable when it comes to critical industrial applications.
V 316H Smooth Pipes are known to be strong and durable and with a high resistance to corrosion. They are made of high-quality 316H SS, which can resist high pressure and high temperatures and their high content of carbon makes them tough even in the coldest of temperatures. These pipeline are suited in the transportation of liquids and gases in pipelines where hygiene and safety are critical concerns. All the pipes are well tested, labelled and stored in plastic wraps individually and then safely packed and labeled to be delivered safely. SS 316H seamless pipes are used in long-lasting, reliable, and clean piping solutions as their superior mechanical properties and anti-rust allow it to serve the industries that require such long piping designs.
