AZ150 is a designation for a specific metallic coating applied to steel, primarily composed of an aluminum-zinc alloy. The “150” signifies a nominal coating mass of 150 grams per square meter (g/m²), distributed over both surfaces of the steel sheet. This coating significantly enhances the steel’s resistance to atmospheric corrosion, offering a balanced combination of […]

ASTM A36 steel is one of the most widely used carbon structural steels in construction and industrial applications. It is a low-carbon steel known for its good strength, formability, and excellent weldability, making it a versatile and economical choice for a variety of projects. Key Mechanical Properties ASTM A36 steel plate is characterized by the

Galvalume and Galvanized are two popular types of metallic-coated sheet steel designed to prevent corrosion. While both serve a similar purpose, they differ significantly in their coating composition, performance characteristics, and ideal applications. Coating Composition Galvanized steel is coated with a layer of nearly 100% zinc. This is typically applied through a hot-dip galvanizing process,

Understanding LSAW Pipes LSAW (Longitudinal Submerged Arc Welded) pipes are a type of steel pipe manufactured by forming steel plates into a cylindrical shape and then welding the longitudinal seam using the submerged arc welding (SAW) process. The term “longitudinal” signifies that the weld seam runs parallel to the pipe’s length. This method is distinct

AZ150 coating is a specific type of aluminum-zinc alloy coating applied to steel sheets, such as those that might be produced by specialists like Shanxi Luokaiwei Steel Company, to provide superior corrosion protection. The “AZ” signifies the aluminum and zinc composition, while “150” indicates the minimum coating mass of 150 grams per square meter (g/m²),

Understanding Pressure Vessel Quality (PVQ) Steel Pressure Vessel Quality (PVQ) steel refers to a range of carbon and alloy steel plates specifically designed for use in the fabrication of welded pressure vessels, boilers, and other equipment intended to operate under pressure. These steels are engineered to withstand internal or external pressure at various temperatures, ensuring

Submerged Arc Welded (SAW) pipes are a significant category of steel pipes manufactured through the submerged arc welding process. This technique involves creating an arc between a continuously fed electrode and the workpiece. The weld area is shielded by a blanket of granular fusible flux, which melts to protect the molten weld pool from atmospheric

OCTG stands for Oil Country Tubular Goods. It is a collective term for a family of rolled steel products used in the oil and gas exploration and production industry. These products are critical for drilling wells and bringing hydrocarbons to the surface. Key Types of OCTG The primary components included under the OCTG umbrella are:

Hollow Structural Sections (HSS) are metal profiles with a hollow tubular cross-section. Typically produced in circular (CHS), square (SHS), or rectangular (RHS) shapes, HSS offers significant structural advantages in various engineering and construction applications. Manufacturing and Key Properties HSS tubes are commonly manufactured through electric resistance welding (ERW) from flat steel strips that are progressively

ASME SA 387 Grade 12 is a chromium-molybdenum alloy steel plate intended primarily for welded boilers and pressure vessels designed for service at elevated temperatures. This material offers excellent heat resistance and anti-corrosion properties due to its specific alloying elements. Key Characteristics and Standards SA 387 Gr 12 is standardized under ASME SA387 and ASTM
