Steel Tubes and Pipes what are the main differences Pipes are usually made of carbon steel or low alloy steel. Tubes instead are made of mild steel, aluminum, brass, copper, chrome, stainless steel, etc. The difference in materials is also a reason for the difference in the cost and applications. Some widely used steel pipe standards or piping classes are: The API range now ISO 3183. E.g.:
Galvanized steel can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements. It has been used used for water-supply pipes or as a strong tubing for outdoor applications. Advantage of galvanized spiral pipe welding process.

Pre-welding of welded steel pipe and its treatmentThe common problems of pre-welding of welded steel tubes, such as erroneous edges, directly lead to the degradation of welded steel tubes or waste materials. Therefore, pre-welding must strictly control the wrong side. When the entire or most of the welded blanks have the wrong edges, the difference is generally due to:
