Polyurethane insulation pipes have good insulation materials and should have low thermal conductivity; It does not deteriorate when exposed to moisture, has good heat resistance, does not corrode metals, is lightweight with many voids; Has a certain mechanical strength and will not be damaged when subjected to external forces; Due to its ease of processing and low cost, today the editor will explain to you the calculation method for its load-bearing capacity.

1： Calculation method for calculating the compressive strength of polyurethane insulation pipes based on their outer diameter specifications and wall thickness (different materials of steel pipes have different tensile strengths)

Pressure=(wall thickness * 2 * tensile strength of steel pipe material)/(outer diameter * coefficient)

2： Calculation method for wall thickness of seamless steel pipe based on its outer diameter and bearing pressure:

Wall thickness=(pressure * outer diameter * coefficient)/(2 * tensile strength of steel pipe material)

3： Method for expressing the pressure coefficient of steel pipes:

Pressure P<7Mpa, coefficient S=8

7<steel pipe pressure P<17.5 coefficient S=6

Pressure P>17.5 coefficient S=4

Formula for calculating the weight of polyurethane insulation pipe support

Outer diameter: D, wall thickness: s; length: m; weight: kg.

Formula: (D-S) * s * 0.02466 * m=kg
