Advantages of Welded Steel Pipe

Advantages of Welded Steel Pipe Structural welded steel pipe can be used for a wide range of mechanical applications. Its close tolerances, good finish, and dense structure make it ideal for parts such as structural support and parts, frames, trailer beds and trailer components, structural components and supports for buildings, bridges, and highways, transportation, machine parts and a wide range of applications in industrial, construction, automotive, appliance and agricultural industries.  Welded steel pipes are generally more cost effective than the equivalent seamless alternative. They are more available both from distributor and mill stocks and from a mill production lead time perspective. With longer lead times SMLS pipes can be exposed to unknown alloying price extras that can fluctuate substantially, thus it can be difficult to plan and predict the true costs for the material. Therefore in addition to faster delivery times for ERW, there is the added advantage of low...

Advantages of Galvanized Seamless Steel Pipe

Advantages of Galvanized Seamless Steel Pipe Galvanized seamless steel pipe is a kind of steel pipe with a anti-corrosion zinc coating.

About micro-and macro-cell corrosion cell corrosion

About micro-and macro-cell corrosion cell corrosion We now have a clue about seamless steel pipes types corrosion’s types per former article. We mention that the form of thick-walled seamless pipe corrosion is divided into micro-and macro-cell corrosion cell corrosion of two categories. Then what are micro-and macro-cell corrosion cell corrosion? The so-called micro-cell corrosion is only a few millimeters or even refers to a few microns away from the anode and cathode are composed of micro-cell function caused by pipe corrosion. The shape feature is very uniform, it is also known as uniform corrosion. As the micro-anode and cathode micro very close distance, so the micro-cell corrosion rate does not depend on the soil resistivity, only on the micro-micro-anode and cathode electrode process. Micro-cell corrosion of buried thick-walled seamless tube of less harmful. Tianjin Xinyue Steel Group have over 30 years experience on  seamless steel pipe , as we already know what ar...
