Plumbing Hanger Load Calculator

Inventory actual independent hanger tributary lengths and filled/attached mass gravity loads; not equal support allocation, anchor force, seismic certification or rod selection.

Description

Hanger gravity load combines filled-pipe mass over a tributary length with attached mass.

Hanger gravity load combines filled-pipe mass over a tributary length with attached mass. Each hanger needs its own assigned inventory.1

The returned values include Modeled hanger gravity loads n, Combined modeled hanger gravity load n. The How section below explains the calculation, input rules and interpretation.

When to use Plumbing Hanger Load Calculator

Use Plumbing Hanger Load Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No equal load distribution, rod selection, anchor or seismic certification is supplied.

Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.

How to use Plumbing Hanger Load Calculator and understand its results

  1. Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
  2. Enter observedTributaryPipeLengthsM, measuredFilledPipeMassKgM, independentlyObservedAttachedMassKg, callerGravityMetersSecondSquared using the field table and calculation rules, then run the tool.
  3. Read modeledHangerGravityLoadsN, combinedModeledHangerGravityLoadN. The explanation below defines the units, signs, ordering and any flags or placeholder values.
  4. If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Enter aligned nonempty nonnegative lengths, filled kg/m and attached kg, plus positive gravity. Return hanger loads and their total in newtons.

load_i=(tributaryLength_i×filledLinearMass_i+attachedMass_i)×gravity

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Limitations and assumptions

No equal load distribution, rod selection, anchor or seismic certification is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Plumbing Pipe Weight Filled Calculator: Filled-pipe mass combines dry linear mass and retained fluid inventory. Heterogeneous segments require their own volume and fill fraction. For a complementary task, use Plumbing Hanger Rod Size Calculator: Hanger-rod selection needs verified assembly capacity at matched conditions. Comparing demand with allowable load leaves the capacity margin explicit.
