History, Uses, and Physical Characteristics of Steel PipeSteel pipe has been used for water lines in the United States since the early 1850s (Elliot 1922). The pipe was first manufactured by rolling steel sheets or plates into shape and riveting the seams. This method of fabrication continued with improve-ments into the 1930s.

What is a steel pipe pile?

After driving the steel pipe to required depth, the steel pipe is filled with concrete of standard specification. In this type of pipe piles, a conical element either made of steel or cast iron is attached to the open bottom by means of welding. This is the conical shoe.See all results for this questionWhat is a disc steel pipe?The disc steel pipe has an arrangement similar to the screw piles, where it has cast iron disc attached to the bottom. The pile sinks into the soil while penetration. So, to facilitate the water jetting process a hole is made at the bottom. These types of piles can be employed in soft or sandy soil.See all results for this questionWELDING OF STAINLESS STEELS AND OTHER JOINING Committee of Stainless Steel Producers, American Iron and Steel Institute.

Preheating can be critical to welding success

Induction heating is considered a very safe option for preheat and postweld heat treatment (PWHT) and is commonly used for pipe welding. It also offers benefits for other part geometries, including flat plates for structural steel applications, as well as for shrink-fit applications.
