PE 파이프 are widely used in urban water supply and drainage, gas, telecommunications, and power industries. When designing and installing PE pipes, wall thickness is a crucial consideration to ensure their safety and reliability. This article will introduce the formula for calculating PE pipe wall thickness and its applications.
PE pipe wall thickness calculation formula
t = (P×D)/(2×S×F)
Where t is the pipe wall thickness in mm;
P is the internal pressure of the pipe in MPa;
D is the outer diameter of the pipe in mm;
S is the tensile strength of the material in MPa;
F is the safety factor, typically 1.5.
Application Example:
Suppose a PE 파이프 needs to be designed to transport water with an internal pressure of 0.6 MPa, an outer diameter of 110 mm, a tensile strength of 20 MPa, and a safety factor of 1.5. According to the above formula, the pipe wall thickness can be calculated as follows:
t = (0.6×110)/(2×20×1.5) ≈ 2.06 mm
Therefore, the wall thickness of this PE pipe should be 2.06 mm.
It is important to note that the above formula only applies to the design and calculation of PE pipes. Actual installation requires consideration of other factors, such as pipe support, connection methods, and ambient temperature. Furthermore, different types of PE pipe materials have different tensile strengths and safety factors; therefore, adjustments need to be made based on the specific circumstances when calculating the wall thickness.
결론
The PE pipe wall thickness calculation formula is an important reference for the design and installation of PE pipes. It helps engineers and technicians calculate the appropriate pipe wall thickness to ensure the safety and reliability of the pipeline. In practical applications, adjustments and optimizations are necessary based on specific circumstances to achieve the best design results.
