Name

Element identifier. Enable to display in 3D view.

Length

Overall length including adjoining flanges (face-to-face dimension)

Weight

Pump weight including flanges. Excludes insulation and fluid content.

Standard weight without overload factors. Fluid and insulation weights apply overload factors from connected pipes.

Material

Material selection from materials database

Manufacturing Technology

Seamless pipe uses Wl=1.0 for ASME B31.1, B31.3, DL/T 5366-2014.

Electric-welded pipe Wl values from database. Details...

GOST 32388-2013 uses different material databases for seamless/welded pipe types.

Temperature

Pump operating temperature.

Adjust per operation mode. View all mode values using button.

Allowable Exceed Factor

API 610 default: 2.0

Other codes default: 1.4. Adjust per manufacturer specifications.

Allowable Loads Verification

Vertical in-line pumps with unanchored supports may use twice the Table 5 allowable values for side nozzles.

For exceeded nozzle loads, apply API 610 Annex F evaluation methods.
