What is Alloy Steel Pipes & Tubes?

Alloy Steel Pipes find their application in scenarios that demand moderate corrosion resistance, excellent durability, and cost-effectiveness. In simple terms, alloy pipes are preferred over carbon steel pipes in areas where the latter may fall short. Alloy steels can be categorized into two classes: high alloys and low alloy steels. Low alloy steels have an alloying content below 5%, while high alloy steels range from 5% to approximately 50% alloying content. Similar to most alloys, Alloy Steel Seamless Pipes exhibit a working pressure capacity approximately 20% higher than welded pipes. Therefore, in applications requiring elevated working pressures, the use of seamless pipes is justified. Although stronger than welded pipes, seamless pipes come at a higher cost. Additionally, welded products pose a higher risk of intergranular corrosion in the heat-affected weld zone. One noticeable difference between an Alloy Steel Welded Pipe and a seamless product is the presence of a visible latitudinal seam along the length of the pipe. However, with technological advancements today, the seam on an Alloy Steel ERW Pipe can be significantly reduced through surface treatment, rendering it nearly invisible to the human eye.

What is Alloy Steel Seamless Pipes & Tubes?

Alloy Steel Seamless Pipes & Tubes are commonly employed in applications that demand moderate corrosion resistance, along with good durability and cost-effectiveness. The High Temperature Alloy Steel Boiler Pipe is typically utilized in scenarios where the ambient temperature reaches 500°C. For instance, in drilling rigs, hollow and thin-walled Alloy Steel Drill Pipes must withstand pressure differentials occurring both inside and outside these Alloy Steel Seamless Pipes. Products made of alloy steel outperform those made of carbon steel. While they are less expensive than stainless steel grades, they exhibit superior corrosion resistance compared to carbon steel pipes, albeit inferior to stainless steels.
