There are probably as many different Stainless steel pipe products on offer in the market as there are different uses for them – and with steel used in almost anything from construction to packaging, it’s hard to keep track of all the different types.
While steel manufacturers have different specs for steel and pipe on offer, there are some broad categorizations to help users make informed decisions.
Firstly, all steel and pipe are alloys in which iron is mixed with carbon and other elements. Steels are therefore described as mild, medium- or high-carbon steels, depending on the percentage carbon they contain. The higher the carbon content, the harder the steel will be.
Metals such as nickel and chromium can also be added to produce alloy steels, for example stainless steel, which is used in high-end, quality steel products. Galvanized steel is coated with zinc to prevent corrosion, for example for the use of roof sheeting.
Galvanized pipe is also mainly used in construction, while corrugated steel pipes will be used more often for drainage, sewer and transportation. Seamless pipe, made from high-quality steel, is used for steam boilers and pipelines.
Steel products can be divided into two groups – flat and long products. Flat steel is used in the manufacture of cars, electrical products, sheeting, coils and pipes. Long products, on the other hand, are mainly used in construction.
Steel and pipe buyers will also come across the terms hot rolled and cold rolled steel. This refers to the heat treatment given during the production process, and has an impact on the qualities of the product. Cold rolled products are normally harder and more brittle, while hot rolled steel and pipe will be softer.
In addition to the different qualities of steel and seamless pipe products, they are also available in a wide variety of different sizes and thicknesses.
