Alloy pipe VS carbon steel seamless steel pipe

Alloy seamless steel pipe is a kind of seamless steel pipe, and its performance is much higher than that of general seamless steel pipe, because this kind of steel pipe contains more Cr, and its high temperature resistance, low temperature resistance and corrosion resistance are unmatched by other seamless steel pipes, so alloy pipes are widely used in petroleum, chemical, electric power, boiler and other industries. Carbon steel seamless steel pipes are used to manufacture annular parts, which can improve material utilization, simplify manufacturing processes, save materials and processing time, such as rolling bearing rings, jack sleeves, etc., which are currently widely made of steel pipes.

Applications of ASTM A252 Piling Pipe

ASTM A252 Grade 1 Piling Pipes are commonly used for large diameters and structural applications such as building and bridge construction. The large diameter helps to evenly distribute the weight of the structure, while the high-quality materials used in the pipes ensure that they can withstand the elements. Moreover, the sturdy construction of these pipes makes them ideal for use in areas prone to earthquakes or other natural disasters. Therefore, ASTM A252 Grade 1 Piling Pipes are an essential component of many large construction projects.

What Are High-Pressure Boiler Tubes?

High-pressure boiler tubes are a type of boiler tube and belong to the category of seamless steel tubes. The manufacturing method is the same as that of seamless tubes, but there are strict requirements on the type of steel used to manufacture steel tubes. High-pressure boiler tubes are often in high temperature and high pressure conditions during use. Under the action of high-temperature flue gas and water vapor, the tubes will oxidize and corrode. The steel tubes are required to have high endurance strength, high resistance to oxidation and corrosion, and good structural stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high-pressure boilers.

How to Identify Inferior SSAW Steel Pipes

SSAW steel pipes, also known as Spiral Submerged Arc Welded (SSAW) pipes, are widely used in construction, oil and gas, and water transportation industries. They are made by rolling low-carbon or low-alloy steel strips into tube blanks at a specific spiral angle and then welding the seams. While SSAW pipes are known for their ability to produce large-diameter pipes with narrower strips, the market is flooded with fake and inferior products. In this guide, we’ll show you how to identify inferior SSAW steel pipes and avoid costly mistakes.
