What is black pipe?

Black gas pipe, often referred to as black iron pipe, is a traditional material used for gas distribution in homes and buildings. It’s a rigid steel pipe with a black coating that protects it from corrosion. Black gas pipe has been widely used for decades in residential and commercial gas installations.

When would black pipe be preferred?

Outdoor Gas Lines: Black pipe is great to use when there is a need for durability and impact resistance.

Commercial Applications: Black pipe is also great to use when there is a need for strength and longevity.

Safety under fire conditions: If there is a need for a more fire-resistant material.

Advantages:

Durability

High Pressure Tolerance

Fire Resistance

Disadvantages:

Less Flexible for Tight Spaces

Corrosion Vulnerability

Higher Material Cost

What is CSST?

Corrugated stainless steel tubing (CSST) is a flexible material that is used for gas distribution in homes and buildings. It’s a newer alternative to traditional black iron pipe and is known for its ease of installation. The flexibility of CSST allows it to navigate through walls and around corners with fewer fittings.

When would CSST be preferred?

Retrofits and Remodels: Great for retrofitting gas lines in existing homes or during remodels due to flexibility, which allows it to be run through walls and tight spaces.

New Gas Line Installations in Residential Homes: It is often used for residential applications because it is easier and faster to install.

Advantages:

Fewer Fittings Needed

Corrosion Resistance

Cost Effective

Disadvantages:

Less Durable Under Impact

Lightning Vulnerability

Lower Pressure Tolerance

Special Installation Requirements
