A critical purpose of this color code for solid wall pipe and conduit is to identify the intended end-use application of fuel gas (methane or propane) piping. This color code provides standardization for solid yellow or black with yellow stripe plastic pipe used in fuel gas applications.
Simply so, what do the different colors of PVC pipe mean?
Blue: Potable Water| White: Irrigation and Water. Green: Sewer. Purple: Reclaimed Water.
One may also ask, what is the difference between PVC and HDPE? Both are strong and durable, but their strengths vary and they have different applications. PVC is heavier and stronger while HDPE is harder and more abrasion and heat resistant. 5. HDPE pipes are found to be able to dampen and absorb shock waves minimizing surges that can affect the system while PVC cannot.
Keeping this in view, what is gray PVC pipe used for?
Polyvinyl Chloride (PVC) — Another material popular for the modern plumbing system pipe, PVC is a white or grey pipe used for high-pressure water, most commonly the main supply line into the house. It isn’t as flexible as PEX, making it less appropriate for smaller interior spaces.
Is it OK to use PVC pipe for hot water?
It is fine to use PVC on your cold water inlet to the hot water heater. But the hot water lines going OUT of the heater should be CPVC. This is why. PVC begins to leach vinyl chloride at temperatures nearing 140 degrees.

What does Schedule 40 mean?
Nominal Pipe Size. Specific pipe is identified by pipe diameter and another non-dimensional number for wall thickness referred to as the Schedule (Sched. or Sch., for example – “2-inch diameter pipe, Schedule 40”).
What is the difference between white PVC and GREY PVC?
However, the kinds of fittings sold for each differs. White PVC pipe fittings tend to be small with tight curves, good for flowing water. Grey PVC pipe fittings tend to be large with broad curves several centimeters in length, good for pushing wire through. Grey PVC fittings often can’t hold pressure.
What color is PVC?
The color of PVC pipe is traditionally white or dark gray, with a technical description of the pipe printed on the side. PVC is available in both rigid form (commonly used in construction and piping applications) and flexible form (found in electrical cable insulation).
Which PVC pipe is strongest?
Schedule 80 pipe is designed with a thicker wall. This means the pipe is thicker and stronger, and as a result it can handle higher pressures. You are probably most familiar with schedule 40 PVC pipe.
What is the difference between green and white PVC?
The green sewer drain pipe is used for the final underground run from a house to the municipal sewer or septic tank. It is PVC, but a lighter weight than white Schedule 40 DWV (Drain-Waste-Vent) pipe. The pipe is intended for gravity-feed waste drain systems and not designed to be pressurized.
What do pipe colors mean?
ANSI/ASME A13. 1 Pipe Color Code Standards Explained. Green with White Lettering – Using a green label with white lettering means that the pipe contains potable water. It could be used for cooling, feeding boilers, or even going to drinking fountains or sinks.
Which is stronger ABS or PVC?
PVC is more flexible than ABS, but ABS is stronger and more shock resistant. ABS is better at handling severely cold temperatures, but it can warp with exposure to direct sunlight. For this reason, ABS can sometimes be the most cost-effective choice even when the pipes themselves are more expensive than PVC.
What color is PVC sewer pipe?
PVC: This white or cream-colored pipe is the most commonly used pipe for drain lines. It’s strong, untouchable by chemicals, and seems to last forever!
Can I use plumbing PVC for electrical?
Electrical PVC is not intended to be exposed to high pressure, as in water lines, and is not rated for use with high-pressure air. Conversely, plumbing PVC should not be used for electrical conduit applications as it does not handle ultraviolet radiation well, and is of reduced rigidity.
Which is stronger PVC Schedule 40 or 80?
Both schedule 40 and 80 PVC are used widely around the world. Each one has its benefits in different applications. Schedule 40 pipe has thinner walls, so it is best for applications involving relatively low water pressure. Schedule 80 pipe has thicker walls and is able to withstand higher PSI (pounds per square inch).
Can you use white PVC for electrical?
Since, in the listings, white plumbing PVC is NOT listed as an electrical raceway, it is not suitable for use as one.
Can I use GREY PVC for water?
Gray conduit is not rated for pressure pipe applications and may not be suitable for potable water use. Stabilizers and other ingredients used in conduit PVC may be toxic; conduit PVC is not held to the same drinking water standards as NSF marked pipe and should not be used in potable water systems.
What is gray plastic water pipe called?
Polybutylene (PB) pipe is a gray plastic tubing that was commonly used as a water-supply plumbing pipe in the years between 1978 and 1995, at which time it was discontinued due to reports of pipes rupturing and causing water damage.
Does CPVC become brittle?
As CPVC ages, it becomes increasingly brittle and can crack or shatter with the slightest impact. Breakdown and deterioration of CPVC pipes can be accelerated by hot outdoor temperatures and by chlorinated water delivery from public utilities.
What’s the difference between electrical PVC and plumbing PVC?
As far as the standards are concerned, there is a difference. “Electrical” PVC supposedly has stiffeners (to give it strength ) and is sunlight resistant. “Plumbing” PVC relies, in part, on the water inside for strength, and is not expected to be exposed to sunlight.
What are the different types of PVC?
Generally, there is Plain PVC, CPVC, UPVC, PVC-U, PVC-M, PVC-O, and Lead Reinforced PVC; which is being phased out due to health concerns. PVC-O, -M, and -O deal with wall thickness. There are also different Pipe Schedules of PVC Pipe; (40, 80, etc.)
What is the difference between PVC and uPVC?
There is only one difference between PVC and uPVC and that is that PVC contains BPA and phthalates, which are two plasticizers that make it more flexible. The “u” in uPVC stands for “unplasticized,” and because it doesn’t have these extra materials, uPVC is often called rigid plastic.
Which is better PVC or HDPE?
HDPE is a softer, more bendable plastic, making HDPE pipe more suitable for lower pressure, tight bending radius situations. On the other hand, PVC is a much stronger and stiffer material, which is why PVC pipes are more widely used for direct burial and trenchless installations.
Is HDPE more expensive than PVC?
In some instances, PVC material can be glued or seamed under water, while HDPE cannot be. On the other hand, HDPE is more able to withstand and dampen (mitigate) shock waves than PVC. While PVC is a heavier and stronger material, HDPE is harder and more heat and abrasion resistant.
