Specifications

The specification screen is only available if MetaPiping is active on your license.

MetaPiping lets you create specifications = predefined choice of piping elements and properties dedicated to a particular project.

It brings together a variety of information :

• Calculation code and edition
• Library of materials
• Library of piping elements

Click the + button to add a new specification or click the - button to remove an unused one.

ATTENTION, do not remove specification used in one or more projects otherwise the projects may not open properly.

1. Header

Properties :

• Units - Metric or USA
• Code - See Codes for more information
• Edition - See Codes for more information
• Max design temperature - °C or °F
• Max design pressure - N/mm² or psi
• Material library - See Materials for more information
• Piping library - See Piping for more information

ATTENTION, a specification has UNITS, so only libraries of materials and piping elements with the same UNITS can be connected.

ATTENTION, when starting a new project, be sure to select a specification that will be compatible with the Units, Code and Edition of the project and do not change these 3 properties during design.

2. Elements

To create a specification, just click to + button and select several pipe sizes :

MetaPiping fills automatically the tables and let you make some choices.

2.1 Pipes

For each size, define the schedule and the material. A pipe knows now its section and its material :

Select then the node connections of the pipe between :

• None
• Butt weld - flush
• Butt weld - as welded
• Fillet weld
• Full fillet weld
• Threaded
• Brazed

Based on this property, define the mismatch or the fillet length [mm or in].

Select then the Long weld type of the pipe between :

• None
• Butt weld flush
• Butt weld as welded

Based on this property, define the Long weld mismatch [mm or in].

Other properties :

Property	Unit Metric	Unit USA	Default
Linear mass + insulation	kg/m	lb/ft	Linear mass of the pipe
Insulation thickness	mm	in	0
External corrosion	mm	in	0
Internal erosion	mm	in	0
Bend thickness	mm	in	Thickness of the pipe

2.2 Bends

MetaPiping automatically fills the table with the corresponding information :

Property	Unit Metric	Unit USA
Long radius	m	ft
Small radius	m	ft
Mass	ton	kips

To know the UNIT of a property, just let the mouse over the property name.

2.3 Reducers

MetaPiping automatically fills the table with the corresponding information :

Fill the Angle property.

Property	Unit Metric	Unit USA	Note
Length	m	ft
Mass	ton	kips
Angle	°	°	Class 1 only

To know the UNIT of a property, just let the mouse over the property name.

2.4 Tees

MetaPiping automatically fills the table with the corresponding informations :

For each combination, you can define the type of tee :

• Branch connection
• WeldingTee
• Non Standard
• Fabricated
• Sweepolet flush weld
• Sweepolet as welded
• Weldolet
• Extruded weldingTee
• Welded-in contour insert
• Branch welded-on fitting
• Lateral connection
• Partial penetration branch connection

Based on the type, some other properties must be filled :

Property	Description	Unit Metric	Unit USA
L1	Length of reinforcement	mm	in
R2	Branch-to-run fillet radius	mm	in
TN	Branch connections and lateral connections CONSTANT thickness	mm	in
Y	Branch connections and lateral connections VARIABLE thickness	mm	in
Thickness type	Variable or constant	-	-
RE	Pad or saddle outer radius for reinforced fabricated tees	mm	in
RX	Transition radius	mm	in
PD	Pad thickness for reinforced fabricated tees	mm	in
Collector length	Half length of the header of welding tees	m	ft
Branch length	Branch length of welding tees	m	ft
Mass	Mass of the tee	ton	kips

2.5 Flanges

MetaPiping automatically fills the table with the corresponding information :

For each size, select the Nominal pressure (Rating) and select the predefined type of flange :

• Welding neck
• Slip-on
• Lap joint
• Threaded
• Socket welding
• Blind

The predefined properties will be shown.
