Welded vs. seamless steel pipe American Piping ProductsJul 02, 2018 · Welded pipe starts out as a long, coiled ribbon of steel called a skelp. The skelp is cut to the desired length, resulting in a flat rectangular sheet. The width of that sheets shorter ends will become the pipes outside circumference, a value that can be used to calculate its eventual outside diameter.

V&M has developed WB 36 steel (15 NiCuMoNb5-6-4) for high pressure piping of boiler feed water system. It is designed to compete against the carbon manganese pipes. It is a low alloy steel with 1.1 % Ni and 0.7 % Cu. Addition of copper increases the strength level.
What are the causes of folds and - Welded Steel PipeFolds and internal cracks in medium and low pressure boiler tubes are the most common forms of defects. Internal folds and internal cracks may be distributed along the entire length of the steel pipe, or located only at both ends or part of the length. When rolling alloy steel pipes, inward folding is particularly easy to occur, and rolling general carbon steel pipes sometimes occur.
