The thermal hardness of carbon steel pipes decreases significantly when the working temperature exceeds 200 degrees, leading to poor wear resistance. Additionally, carbon steel pipes have low hardenability.Carbon steel pipes also have some disadvantages. For example, compared with stainless steel pipes, carbon steel pipes have slightly worse co...

To calculate the weight of a steel tube, use this formula:Weight = π × [(Outer Diameter / 2)² − (Outer Diameter / 2 − Wall Thickness)²] × Length × Density of SteelThe density depends on the steel type:Mild steel: 7.88 g/cm³Carbon steel: 7.84 g/cm³Stainless steel: 8.03 g/cm³This formula gives the theoretical weight based on uniform wall thicknes...

The most common method of connecting carbon steel pipes is through welded connections. These connections can be made using various methods, including electric welding, gas welding, and submerged arc welding. Manual arc welding and gas shielded welding are commonly used in electric welding. ...

Carbon steel pipe processing refers to the process of processing raw steel into specified specifications and sizes. Carbon steel pipe is a commonly used industrial pipe. Due to the different characteristics and uses of carbon steel pipes, the processing technology will also be different. Generally speaking, the processing technology of carbon steel pipes...

Hot-rolled steel pipes have an outer diameter ranging from 32mm to 630mm and a wall thickness of 2.5mm to 75mm. Cold-drawn steel pipes, on the other hand, have an outer diameter ranging from 5mm to 200mm and a wall thickness of 2.5mm to 12mm. Seamless steel...

The structural strength of steel pipes depends on factors such as the material type (such as carbon steel, stainless steel, high-strength steel), the manufacturing process (seamless, welded pipe), and whether it is a composite structure (such as steel tube concrete). In high-rise buildings and bridges, by pouring concrete into the steel pipe to...

Structural pipes are categorized in various ways based on material, standards, and performance grades, depending on their application scenarios and performance requirements. For example, they can be classified by standards such as GB/T 8162 and ASTM A53; by manufacturing process, they can be divided into hot-rolled, cold-drawn, and cold-rolled ...
