What is the difference between Schedule 40 and Schedule 80 electrical PVC?

What is the difference between Schedule 40 and Schedule 80 electrical PVC?

Schedule 40 PVC conduit is cheaper and has a larger inside diameter, so it’s easier to pull wires through it. The plastic on Schedule 80 is thicker, but the conduit has the same outside diameter as 40, so the inside diameter is smaller.

What schedule is rigid PVC?

Schedule 40 and 80 rigid PVC conduit fittings are used ex- posed, encased in concrete, concealed in walls and in direct burial applications.

Can Schedule 40 PVC be used above ground?

Schedule 40 PVC Conduit is used in walls, floors and ceilings in accordance with NEC 352. According to NEC 352 it can also be buried directly into the earth, encased in concrete, and used in areas exposed to direct sunlight. It is not designed for use above ground or in walls, floors or ceilings.

Can you mix Schedule 80 and Schedule 40 PVC?

As mentioned earlier, both schedule 80 and schedule 40 PVC pipe have the exact same outside diameter. This is possible because schedule 80’s extra wall thickness is on the inside of the pipe. This means schedule 40 and 80 pipe do fit together and can be used together if necessary.

What is Schedule 80 pipe used for?

Schedule 80 PVC pipe is used for industrial and higher pressure water flow applications. Schedule 80 PVC pipe can handle 140 degrees F in temperature. The pipe comes in standard 10′ or 20′ sections and is available in plain end or belled end so no coupling is needed for installation.

Is Schedule 40 PVC rigid?

Schedule 40 PVC pipe is strong, rigid, and can handle pressure applications.

What is the difference between Schedule 40 and Schedule 80?

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). This makes it ideal for industrial and chemical applications.

Can you run PVC conduit outside?

Schedule 80 pipe can be connected to structure above ground since you said it was listed sunlight resistant, so that is an option.

What is the difference between white PVC and GREY PVC?

Grey PVC is used as electrical conduit and is better suited for sunlight resistance. The fittings for this type of pipe are made to pull wires into and not intended for containing pressured fluids. White is for plumbing applications. Both use the same solvents and glues.
