Properties

Property

Description

Name

Element identifier. When checked, displays in 3D view.

Get properties from matching pipe

Import properties from adjacent pipe element.

Calculate weight automatically

Automatically calculate tee weight based on torus volume using adjoining pipe wall thickness.

Material

Material selection from materials database

Weight

Tee weight (including flanges) excluding insulation and fluid content. Enter nominal weight without overload factors. PASS/START-PROF automatically calculates fluid and insulation weights with appropriate overload factors from adjoining pipes.

Longitudinal Weld Joint Efficiency Factor, E

Longitudinal weld joint efficiency factor. More information...

Manufacturing technology

For ASME B31.1, ASME B31.3, and DL/T 5366-2014, seamless pipe uses Wl=1.0. Electric-welded pipe uses Wl from database. More information...

When using GOST 32388-2013, material properties are retrieved from different databases based on pipe type (seamless or welded).

Header wall thickness, tn

Header wall thickness used for section modulus (Z) calculations.

Header and branch SIF

io - out-plane SIF, ii - in-plane SIF, it - torsion SIF, ia - axial stress intensification factors

Header and branch flexibility factors

ko - out-plane, ki - in-plane, kt - torsion, ka - axial flexibility factors. Zero value indicates rigid connection.

PASS/START-PROF creates custom expansion joints on branch and header pipes with specified flexibilities:

PASS/START-PROF tee object model:

Internal tee model used for analysis. Header and branch pipes have different wall thickness than connected pipes. Flexible springs model header (2) or branch (1) flexibility when using ASME B31J. Rigid element eliminates branch element (3) "dummy" flexibility.
