How do the installation time costs typically compare between flanged ductile iron pipe?

Several key factors lead to increased installation time costs for flanged ductile iron pipe, they include:

• The extensive preparation needed for ductile iron pipe ends, which includes cutting, chamfering, and deburring aids in ensuring a proper seal at the flanged connections.
• This additional preparatory step results in an elongated installation timeframe.

• Accurate flange alignment is critical for flanged ductile iron pipe connections. This may need specialized tools and extra time for the correct positioning and securing of the flanges.
• Misalignment could result in leaks or other issues, making this a process more time-consuming than simpler pipe connections.

• Flanged ductile iron pipe connections need a specific bolt tightening sequence along with accurate torque values to form a reliable seal.
• Ensuring and achieving the correct bolt tension lengthens the installation process.

• Selecting and installing the right gasket material for the flanged connection is an essential step that requires extra time and attention.
• Improper gasket installation can compromise the joint’s integrity.

• Depending on the gasket or sealant type used, there could be a necessary curing or drying period post-installation enabling the materials to set fully.
• This could prolong the overall installation process.

• The use of particular tools and equipment, like flange alignment clamps, torque wrenches, and chain wrenches, increases the installation process duration as workers learn their proper usage.

• The required higher level of expertise and training for flanged ductile iron pipe installation, as opposed to simpler pipe connections, could result in longer installation durations, especially for less seasoned crews.
