The data of Brinell hardness measurement is accurate and stable, and it is suitable for detecting unquenched seamless steel pipes, cast iron steel pipes, non-ferrous metals or light and soft bearing alloy steel pipes.
Read moreCold rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, as well as carbon thin-walled steel pipes and alloy thin-walled steel pipes.
Read moreThe strength of thick-walled spiral steel pipes is generally higher than that of large-diameter straight seam steel pipes.
Read moreSeamless steel pipe penetration testing has simple principles, flexible methods, and strong adaptability. It can detect surface opening defects in any direction at one time.
Read moreThe characteristics of plastic-coated composite steel pipe: It not only has the strength of steel pipe, but also has the advantages of plastic pipe corrosion resistance, wear resistance, and low fluid resistance. It is a new type of water supply and anticorrosion pipeline.
Read moreLarge-diameter steel pipes are pickled using an acid solution to remove oxide scale and rust on the surface of steel, called pickling. Acids for pickling include sulfuric acid, hydrochloric acid, phosphoric acid and mixed acids.
