AS 2885.1 Gas And Liquid Pipeline Schedule

Calculate AS 2885.1 pipeline schedules for diameter, wall thickness, mass, weight, and stress.

For AS 2885.1, the fabrication tolerance is included in the design factor. The fabrication tolerance is not required provided that the tolerance is within the relevant specification.

Use the Result Table option to display schedule tables. Refer to the links below for other options.

CALCULATOR : AS 2885.1 Section 5.4.3 Pipeline Allowable Stress [FREE]   ±

Calculate pipeline allowable stress from specified minimum yield stress (SMYS) and design factor (AS 2885.1 section 5.4.3).

Use the Result Table option to display a table of SMYS and allowable stress versus material grade for the selected material schedule.

Tool Input

  • syutype : Line Pipe Stress Type
  • mattype : Material Type
    • SMYSu : User Defined Specified Minimum Yield Stress
  • dfactype : Allowable Stress Factor Type
    • Fdu : User Defined Allowable Stress Factor

Tool Output

  • Fd : Allowable Stress Factor
  • SMYS : Yield Stress
  • Sa : Allowable Stress
CALCULATOR : AS 2885.1 Pipeline Diameter And Wall Thickness Schedule [FREE]   ±

Calculate AS 2885.1 pipeline diameter and wall thickness.

The pressure design wall thickness is equal to the nominal wall thickness minus the corrosion allowance. The fabrication allowance is accounted for in the design factor (an additional fabrication allowance is required in some cases). Select the pipe schedule (NPS or ISO etc), pipe diameter and wall thickness, or use the user defined option. Use the Result Table option to display the pipe schedule with nominal wall thickness and pressure design wall thickness for the selected diameter.

Tool Input

  • schdtype : Line Pipe Schedule Type
  • diamtype : Line Pipe Diameter Type
    • ODu : User Defined Outside Diameter
    • IDu : User Defined Inside Diameter
  • wtntype : Wall Thickness Type
    • tnu : User Defined Wall Thickness
  • c : Wall Thickness Corrosion Allowance

Tool Output

  • ID : Nominal Inside Diameter
  • OD : Nominal Outside Diameter
  • OD/tn : Diameter Over Wall Thickness Ratio
  • tn : Nominal Wall Thickness
  • tp : Pressure Design Wall Thickness
CALCULATOR : AS 2885.1 Pipeline Mass Per Length And Total Mass Schedule [FREE]   ±

Calculate AS 2885.1 pipeline mass per length and total mass.

The total mass can be used to calculate pipe joint mass (from joint length), or total construction mass (from total length). Select the pipe schedule (NPS or ISO), pipe diameter and wall thickness, or use the user defined option. Use the Result Table option to display the pipe schedule with unit mass and total mass for the selected diameter.

Tool Input

  • schdtype : Schedule Type
  • diamtype : Diameter Type
    • ODu : User Defined Outside Diameter
    • IDu : User Defined Inside Diameter
  • wtntype : Wall Thickness Type
    • tnu : User Defined Wall Thickness
  • modptype : Material Property Type
    • ρpu : User Defined Pipe Density
  • L : Pipe Length

Tool Output

  • ρp : Pipe Density
  • ID : Nominal Inside Diameter
  • M : Pipe Total Mass
  • OD : Nominal Outside Diameter
  • OD/tn : Diameter Over Wall Thickness Ratio
  • m : Pipe Mass Per Length
  • tn : Nominal Wall Thickness
CALCULATOR : AS 2885.1 Pipeline Unit Weight Including Contents And Buoyancy (Multi Layer Pipe) [FREE]   ±

Calculate AS 2885.1 pipeline unit weight including contents and buoyancy for multi layer pipelines.

Calculate weight per length for dry empty, dry full, wet empty and wet full pipelines. Change the number of layers on the setup page. The external fluid density is not required for dry pipelines.

Tool Input
