The most common materials used to make gas pipes are steel, black iron, polyvinyl chloride (PVC), high-density polyethylene (HDPE) and copper. PVC pipes will work well for natural gas lines and water supply. They are usually available in 10 foot and 20 foot sizes, and come in different diameters. The size ranges from ½ inch to 6 inch to choose one depending on the purpose.
If you want to fix PVC pipes, you will need solvent cement, primer or a pressure fitting. However, you will have to remember not to install PVC pipes where sunlight flows directly. When exposed to hot water or direct sunlight, PVC can be damaged. If you use it for natural gas, make sure it flows through a cold or dark area.
Remember that these pipes must be installed by professionals who know the work. They usually come in lengths from 2 inches to 10 feet and have a diameter of ¼ inch to 2 inches. Many people use a black pipe to transfer natural gas to the house from the outside. People have been using copper pipes for years to transfer hot and cold water.
These tubes range in length and are usually between 2 and 10 inches in size. Each dimension from ½ to 1 inch ensures that water and gas flow easily. Steel pipes can be used on the ground as long as corrosion due to the environment and transport gas is not a problem. Steel and copper tubes are the most commonly used materials in the interior of buildings.
Copper pipes used in gas systems must be L or K type and approved for gas. Yellow brass pipes may be approved for indoor installations. Aluminum tubes should not be used on the ground. Aluminum is not approved in all jurisdictions.
Ductile iron pipes may be approved in some jurisdictions for underground work. Water and gas require piping to supply residential homes and businesses. Gas supplies energy to stoves, water heaters, ovens and other devices. The two most common types of steel pipes used to transport water and gas are black pipes and galvanized pipes.
Confusion is common among homeowners, and even some professionals, as to where to use these steel pipes and under what circumstances. In my experience, both types of pipes work well, and the IRC and the National Combustible Gas Code allow both, along with stainless steel corrugated tubing (CSST) and copper tubing (with some limitations) to be used for natural gas distribution pipelines. The pipes upstream of the gas meter and the meter itself are usually the responsibility of the gas company. But natural gas is much cleaner than it was 40 years ago, and almost all fuel gas goes through a sulfur recovery unit before entering the distribution system today.
