What is the difference between PVC schedule 40 and PVC 80?
There are two common types of PVC pipe - schedule 40 PVC and schedule 80 PVC. Schedule 40 PVC is usually white in color and schedule 80 is usually a dark gray (they can also be found in other colors). Their most important difference, though, is in their design. Schedule 80 pipe is designed with a thicker wall.
What is Schedule 40 black pipe?

What is meant by Schedule 40 pipe?
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. What Does Nominal Pipe Size Mean?
What is the difference between schedule 40 and 80?
The major difference between schedule 40 and schedule 80 pipe is the wall thickness, inside diameter, and their weight. Schedule 80 will have a greater wall thickness, a smaller inside diameter and a higher weight than Schedule 40 pipe at a given nominal pipe size. Of course, all of these numbers will vary based on the nominal pipe size. There are also many other pipe schedule numbers as well.
Which PVC pipe is rigid?

PVC is produced in two general forms: a rigid or unplasticized polymer (RPVC or uPVC), and the second as a flexible plastic. In its base form, PVC is characterized by its rigid yet brittle structure.
What's the difference between Schedule 40 PVC and regular PVC?
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).

Schedule 40 pipe refers to the nominal wall thickness, not the grade. Therefore, the chemical composition of a pipe schedule is not necessarily uniform. However, schedule 40 pipe is made from low-carbon steel, usually grade A53 steel pipe.
How do you make PVC pipe flexible?
You can bend PVC pipes by applying heat to the part where you want the bend to go. PVC is what scientists call an amorphous polymer, which means the particles that make up its structure are not arranged in fixed arrays. Applying heat to the PVC, therefore, softens it up and makes it easier to bend.

What is the difference between PVC and rigid PVC?
The most notable difference is this: flexible PVC compounds have plasticiser added to them, while rigid ones have little to none. This plasticizer makes the PVC resin more flexible, which means it's soft and supple in comparison. You'll see these “rubbery” characteristics in the likes of garden hosepipes.
