Pipe Weight Charts

Although the standard provides formulas for calculations, they are still too cumbersome for everyday viewing use, so ASME B36.10M Table 1 provides detailed information including pipe nominal diameter, wall thickness, schedule grade, and the corresponding pipe weight in lb/ft or kg/m.

pipe weight chart-ASME B36.10M.pdf

ASME B36.10M Provides a nominal flat end weight based on the weight of the calculation method and is also based on the outer diameter (OD) and wall thickness (WT) of the steel pipe classification.

For a table of pipe weights for threads, check out the ASTM A53 threaded and coupled pipe weight chart (Table 2.3).

Selection of Wall Thickness of Steel Pipe

The choice of wall thickness depends mainly on the resistance to internal pressure under given conditions.
capacity should be based on specific values from the Boiler and Pressure Vessel Code, ASME B31 Pressure Piping Code, with the construction code as the construction specifications.

Definition of a Schedule Number

Schedule numbering system for pipe size and wall thickness combinations.

Schedule Number = 1000 (P/S)

P represents the design working pressure of the pipe, usually in psi (pounds per square inch)

S represents the minimum allowable stress of the pipe material at operating temperature, also in psi (pounds per square inch).

Schedule 40

Schedule 40 is a widely used wall thickness classification standard in piping engineering that specifies the standard wall thickness that a pipe of a certain outside diameter should have.

Advantages of Schedule 40

Medium Strength and Economy
Schedule 40 provides good strength and pressure resistance while maintaining a reasonable balance between cost and weight for most low and medium-pressure applications.

Wide range of compatibility
Many fittings and connections are designed based on Schedule 40 sizing standards, making this type of piping easy to integrate and install with other systems.

Standardized production
Due to its popularity, manufacturers are able to mass-produce Schedule 40 pipes and fittings, further reducing costs and increasing product availability.

Adaptable
Schedule 40 pipe is available in medium wall thicknesses for residential, commercial, and light industrial applications for a wide range of fluid systems, from water piping to gas distribution.

As a result, Schedule 40 has been adopted for its economy, compatibility, and applicability in a wide variety of piping systems, ranging from domestic water systems to industrial fluid transportation.

Schedule 80

Schedule 80 pipe is suitable for applications requiring higher pressure and abrasion resistance due to its reinforced properties.

Advantages of Schedule 80

Enhanced Pressure Resistance
Schedule 80 has a thicker pipe wall than Schedule 40, providing higher pressure resistance for high-pressure applications.

Corrosion and abrasion resistance
The thicker wall thickness allows Schedule 80 pipe to perform better in corrosive or abrasive environments, extending service life.

Suitable for harsh environments
This type of piping is commonly used in the chemical, oil, and gas industries, where piping can be exposed to extreme temperatures and chemicals.

High safety standards
Enhanced structural strength gives the Schedule 80 pipe an advantage in terms of safety, especially when subjected to high internal pressures.
