Line List User Guide

What is Line List?

Line List is your master database of all piping lines in the project. Every pipe, from small drain lines to major process lines, has specific requirements for materials, testing, and construction. This module stores all that critical information.

Getting Started

To access Line List:

1. Login to the system
2. Click on Manufacturing in the main menu
3. Select Line list from the submenu

Understanding Line Data

What's in a Line Record?

Each line contains:

• Line Number: Unique identifier (like 1001-P-6"-CS-150)
• Service: What flows through the pipe (steam, water, oil, etc.)
• Design Conditions: Pressure and temperature requirements
• Material Specification: What the pipe is made of
• Testing Requirements: NDT percentages and pressure test info
• Special Requirements: Insulation, painting, tracing

Line Number Format

Typical format: XXXX-Y-Z"-MM-RRR

• XXXX: Line number (1001, 2505, etc.)
• Y: Service code (P=Process, U=Utility, etc.)
• Z": Nominal pipe size (6", 12", etc.)
• MM: Material code (CS=Carbon Steel, SS=Stainless, etc.)
• RRR: Pressure rating (150, 300, 600, etc.)

Pressure Testing

Hydrostatic Test:

• Acceptance Criteria: No leaks, no permanent deformation

Pneumatic Test:

• Test Pressure: Lower than hydrostatic
• Test Medium: Air or inert gas
• Safety Requirements: Extra precautions needed
• When Used: When water testing not practical

Special Requirements

Insulation and Tracing

Heat Tracing:

• Type: Electric or steam tracing
• Temperature: Maintain temperature
• Coverage: Full line or partial
• Controls: Temperature monitoring

Insulation:

• Type: Mineral wool, foam, etc.
• Thickness: Based on service temperature
• Weather Protection: Aluminum cladding
• Fire Rating: Special fire protection

Painting and Coatings

External Coating:

• Primer: Base coat specification
• Finish Coat: Top coat color and type
• Special Coatings: Chemical resistant, high temp
• Touch-up: Field painting requirements

Internal Coating:

• When Required: Corrosive services
• Type: Epoxy, phenolic, etc.
• Application: Before or after installation
• Quality Control: Holiday testing
