  Advantages and Performance of Hot-Dip Galvanized Square Tubes

  The production and application of galvanized square tubes have gradually established corresponding methods after many years of social experience. Cold-dip galvanized tubes have gradually withdrawn from the stage of application due to product shortcomings. Hot-dip galvanized steel pipes are made by reacting molten metal with iron substrate to form an aluminum alloy layer, so that the substrate and the coating are closely bonded. Hot-dip galvanizing is to first pickle and passivate the square steel pipe. In order to remove the impurities on the surface of the square steel pipe, after pickling and passivation, it is cleaned in an ammonium chloride or magnesium chloride solution or a mixed solution of ammonium chloride and magnesium chloride, and then sent to the hot-dip galvanizing tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

  Mild Steel Pipes: Specifications, Features & Applications

  Mild Steel Pipe (MS Pipe) is manufactured using low carbon steel (less than 0.25%). Due to the low carbon content, the steel pipe does not harden and is easy to work with. Since mild steel pipe is made of low carbon steel, it can be easily welded and formed into pipes and tubes of various shapes and sizes. These pipes are mainly used in industries and engineering applications where corrosive fluids are used. In addition, MS pipes are also used in drinking water supply, i.e., pipes, fire protection, and HVAC (heating, ventilation, and air conditioning). Mild steel does not corrode because its surface is coated with paint, varnish, and other metals, which makes it durable and can work in very harsh conditions. In addition, mild steel pipes can also withstand certain temperatures.

  Analysis of eight surface defects of seamless steel pipe

  In today’s industrial landscape, where steel materials are used extensively, seamless steel pipes have become essential components in sectors such as oil and gas, chemical processing, power boilers, machinery manufacturing, automotive, and aerospace. Their advantages—high strength, excellent pressure resistance, and the absence of weld seams on both inner and outer walls—make them particularly suitable for high-performance and high-pressure applications. However, unlike ERW (Electric Resistance Welded) pipes or SSAW (Spiral Submerged Arc Welded) pipes, which may face different types of welding-related flaws, seamless pipes are particularly prone to surface defects formed during hot rolling or cold drawing processes.Surface quality plays a critical role in performance and post-processing operations. This article provides a comprehensive analysis of eight common surface defects in seamless steel pipes, their causes, and the corresponding preventive measures—insights that also offer valuable references for manufacturers of drill pipes and other tubular products.​
