An Alloy Steel Seamless Pipe's working pressure capability is around 20% higher than a welded pipe, similar to most alloys. As a result, the use of a seamless pipe is justified in applications that require a higher working pressure. The cost is substantially more than a welded pipe, despite the fact that it is stronger. Alloy Steel Seamless Pipes & Tubes are utilised in applications that demand moderate corrosion resistance, as well as good durability and a low cost.
