You can find Schedule 40 steel pipes in galvanized or black steel varieties in hardware stores. ![]() Black steel pipe is not suitable for carrying drinking water because it rusts easily. Other possible uses include drain lines and heating pipes. You can find black pipe in heat exchangers as well, where it transports heating and cooling water. Black pipe is also used for fire sprinkler systems because of its strong resistance to heat. What is Black Steel Pipe?īlack steel pipe is used to transport water and natural gas from their sources to homes and businesses. The zinc added to galvanized pipe makes it more expensive than regular black steel pipe. This material also contains lead, which can taint drinking water. Flaking zinc can also cause a galvanized steel water pipe to burst. ![]() It can’t be used for gas lines because the zinc clogs the line when it begins to flake. It’s best reserved for large construction projects and has a lifespan of 40 years.ĭespite the zinc coating, galvanized pipe still corrodes faster than copper and PVC pipe. ![]() Galvanized pipe has many other uses besides water and sewer lines, including fences, railings, scaffolding, and farm irrigation systems. It’s also a suitable material for sewer plumbing. Galvanized pipe has been used as a water supply line material in homes and businesses for more than 30 years. The addition of zinc improves the pipe’s resistance to corrosion and mineral deposits, increasing its life expectancy. Galvanized pipe is a steel pipe coated with zinc. Schedule 10 is reserved for light-duty applications. If the pipes are exposed, or if there is a need to transport high-temperature or high-pressure water or gas, then Schedule 80 or Schedule 160 pipes may be required. This standard offers an ideal balance between cost, strength, and ease of installation. Schedule 40 is the most common pipe thickness used in construction work. These include Schedule 10, Schedule 40, Schedule 80, and Schedule 160. The American National Standards Institute has standardized pipe wall thicknesses for different applications.

Pipe, the SCH 40 wall thickness is 0.154-inches.Schedule 40 galvanized or black steel pipes are commonly used for gas and water lines, but that’s not all they can be used for. ForĪn NPS 1 pipe, an SCH 40 wall thickness is 0.133-inches, while for an NPS 2 Let’s take the same SCH 40 wall thickness as before. Larger the nominal diameter of the pipe, the thicker the wall becomes, even for ![]() With internal working pressure of 450 psi and an S value of 12,000:Īlteration of the wall thickness depending on the NPS (Nominal Pipe Size). Let’s have a look at an example of a pipe Internal working pressure od the pipe, while S signifies how much stress the Obtain the right pipe schedule for a given usage scenario: The best way to see the relationship between pipe size, schedules and wall thicknesses is simply to refer to a conversion chart (below): Image Credit: Metal Supermarkets The following equation can be used to The SCH 80 wall thickness, on the other hand, is the same as the previously used XS wall thickness for pipe sizes up to NPS 10. For NPS 12 or smaller pipes or pipes with outer diameter of around 12 inches, SCH 40 is the same wall thickness of the previously used value. In the past, only three pipe wall thicknesses were used, but these measurements are very vague and aren’t used today Today, fourteen pipe schedule numbers are used: SCH 5, SCH 5S, SCH 10, SCH 10S, SCH 20, SCH 30, SCH 40S, SCH 60, SCH 80, SCH 80S, SCH 100, SCH 120, SCH 140, and SCH 160.
