Types of Gas Piping

Steel, black iron, PVC, HDPE, copper, and polyvinyl chloride are the most often used materials to create gas piping. Before installing any of these items, make sure to check with your local utility to find out what is permitted in your region as certain utilities prohibit some of these products.

• Corrugated Stainless Steel Tubing
• Galvanized Steel
• Black Iron
• PVC
• HDPE
• Copper

Corrugated Stainless Steel Tubing

Corrugated stainless steel tubing is adaptable and simple to install, and it works well in confined spaces and in places where there is a significant risk of natural disasters. Flexible corrugated stainless steel tubes can eventually crack, despite the fact that their elasticity might limit the damage. Only use this material for gas piping within buildings.

Galvanized Steel

Gas pipes made from galvanized steel are energy efficient and durable. Used for both interior and exterior gas lines, galvanized steel pipes are ideal for water supply lines. This material is often found in older homes and isn’t used in new constructions today because it’s labor-intensive compared to other materials.

Black Iron

Black iron is the most common material used to make gas pipes, both inside, and outsides. The material is strong, heat resistant, and can fit together to form a strong seal. Over time, however, black iron can corrode and its sealant can depreciate. If your gas pipes are made of black iron, consider hiring a professional for routine maintenance.

PVC

PVC gas pipes work well for underground exterior gas lines because they’re durable and resistant to corrosion. PVC pipes are an inexpensive solution, but some locations don’t allow them as they can break during the installation process.

HDPE

HDPE pipes are ideal for subterranean external lines, just like PVC pipes. Although these flexible, low-cost plastic pipes are susceptible to damage from subsurface objects like pebbles and tree roots.

Copper

Given that certain localities forbid them, copper gas pipes have just a few applications. Copper pipes must adhere to severe code requirements because their projected lifespan is only 20 years.
