What Is The Pressure on Galvanized Seamless Pipes?

With the continuous improvement of building quality and industrial standards, the durability and safety requirements of pipeline systems are also getting higher and higher. The galvanized seamless pipe is gradually becoming an ideal choice for fire protection, air conditioning, circulating water systems, and gas transportation due to their excellent corrosion resistance and outstanding pressure bearing capacity. The following will deeply analyze the calculation method and key influencing factors of the pressure on galvanized seamless pipes to help you make wise decisions in engineering material selection and system design.

What is galvanized seamless pipe

Galvanized seamless pipes are seamless pipes processed by hot-dip galvanizing. After being covered with a thick zinc layer, their corrosion resistance is significantly improved and their service life is extended. Compared with other seamless pipes, galvanized seamless pipes perform better in harsh environments.

Calculation method for pressure on galvanized seamless pipes

Generally speaking, the pressure on galvanized seamless pipes can be calculated using a specific formula. This formula takes into account factors such as the wall thickness, outer diameter, tensile strength of the steel pipe material, and safety factor of the seamless pipe. The formula is:

“Pressure = (Wall Thickness × 2 × Tensile Strength of Steel Pipe Material) / (Outer Diameter × Coefficient)”

(Wherein, the safety factor is selected according to the pressure range to ensure the safety of the seamless pipe when it is under pressure.)

The specific pressure to be borne needs to be determined according to the actual situation. For example, a 20# seamless steel pipe with an outer diameter of 114mm and a wall thickness of 12mm can withstand a pressure of 14.39MPa under the condition of a safety factor of 6. However, its pressure resistance is not constant, but is affected by many factors.

Factors affecting the pressure resistance of galvanized seamless pipes

1. Wall thickness

Wall thickness is one of the key factors affecting the pressure resistance of galvanized seamless pipes. Generally speaking, the thicker the wall, the stronger the pressure resistance of galvanized seamless pipes.

2. Outer diameter

The outer diameter also has a certain influence on the pressure resistance of galvanized seamless pipes. Under the same wall thickness and material conditions, galvanized seamless pipes with smaller outer diameters tend to have higher pressure resistance.

3. Tensile strength of steel pipe material

Steel pipes of different materials have different tensile strengths, which affects the pressure bearing capacity of galvanized seamless pipes. The higher the tensile strength of the material, the stronger the pressure bearing capacity of the galvanized seamless pipe made of it. Seamless pipes of different materials such as mild steel tube and carbon steel pipe have different pressure bearing capacities due to different material properties.

4. Safety factor

The safety factor is a factor introduced to ensure that the seamless pipe has sufficient safety when under pressure. Selecting a suitable safety factor according to the pressure range can ensure the reliability of the seamless pipe in practical applications.

Summary

In summary, the pressure bearing capacity of galvanized seamless pipes is not a fixed value, but is affected by many factors. In practical applications, it is necessary to select the appropriate seamless pipe specifications and safety factors according to the specific situation to ensure its pressure bearing capacity and safety.
