Austenitic stainless steels are the most commonly used in piping systems. These are designated by the suffix L.” Stainless steels are susceptible to stress corrosion cracking and so exposure to chloride compounds should be avoided. Stainless steel piping is used whenever iron dissolution cannot be tolerated.
For example, a welding discontinuity only a few centimeters long can reduce the strength of the pipe by a factor of 5 and lead to disastrous failure 2. With a tube inventory covering all the size range up to outside diameter 2500 mm and wall thicknesses up to 50 mm, we are able to satisfy most of your tube requirements in a wide range of steel grades. Since the beginning of the year we have implemented our stock with the full range of welded tubes from Ø 219 to Ø 508 mm according to the following specs:
As manufacturing processes have evolved and become more complex, steel buyers’ options have expanded to suit many unique needs across a variety of industries. Piping industry professionals can become better buyers by examining the types of steel available today and understanding why some steels make great pipe and others do not. According to the American Iron and Steel Institute (AISI), ferrous material is designated as carbon steel when its core makeup is specified to include no more than 1.65 percent manganese, 0.60 percent silicon and 0.60 percent copper and when no minimum content is specified for other alloying elements.
Because it contains relatively few alloying elements and in low concentrations, carbon steel pipe is relatively inexpensive. The oil & gas and power generation industries often favor alloy pipe due to its toughness. There’s no one combination of iron and alloying elements that makes stainless steel what it is. Instead, stainless steel refers to the fact that products made from it do not rust.
These alloys work together to interact with oxygen in water and air to quickly form a thin but strong film over the steel that prevents further corrosion. Due to its aesthetic appeal, stainless steel is often chosen if pipe must be visible in public or professional settings. Sometimes called super-alloys, tool steels are not well-suited for piping products.
For another, the amount of alloying elements present in tool steels make them harder to form into piping products.
