Having detailed knowledge about the dimensions is extremely important if you’re dealing with anything related to PVC. However, I admit that it is a challenging process, often confusing to the point you don’t even know what to do.

What is Pipe Scheduling? 

Scheduling is a process for determining the measurement of PVC pipes, and take note that it has nothing to do with the human concept of time management. Instead, scheduling is a fabrication plan utilized to determine a plumbing material’s wall thickness. In simple language, a pipe schedule is a fixed standard for how thick a pipe’s wall must be established on how large or wide the pipe is in diameter.

Hypothetically, a pipe schedule is a table with complex data that has been prefigured with standardized textbook values for pipes and fittings. For instance, manufacturers looking to produce 2″ Schedule 40 PVC pipe will know the exact thickness of the pipe wall categorized as a 2″; Schedule 40 PVC pipe.

On the surface, as the pipe schedule value increases, the pipe wall thickness also zips. The same phenomenon is noticeable in Sch 40 and 80 pipes. That means Schedule 80 pipes will always have thicker sidewalls than Schedule 40 pipes when utilized for a specific pipe size or diameter. The pipe’s wall thickness is the main criterion that changes and corresponds with the pipe’s consistently changing Inner diameter (ID). Therefore, pipe schedules usually don’t affect Nominal Pipe Size (NPS) and Outer Diameter (OD).

How to Apply Scheduling to Determine Pipe Sizes and Dimensions?

As established earlier, Pipe scheduling is more important than people give it credit for. It is utilized by construction and engineering firms, contractors, plumbing handlers, and installers. A pipe schedule is a fantastic way to understand the pipe’s suitability for its intended application. Professionals, while evaluating and estimating plumbing components and materials, will go for the pipe size and schedule rating that has been designed to meet or exceed the planned application’s demands.

In layman’s terms, Pipe scheduling is the key to determining which plumbing equipment is best for the job. To get the best results in plumbing situations, it is necessary to analyze and understand pipe thickness, pressure ratings, chemical suitability, and total costs. All these attributes are in line with pipe scheduling ratings.

FAQs 

Is Schedule 40 PVC pipe strong?

Ans. Schedule 40 PVC pipes are strong, rigid, and can handle good pressure, specifically in household applications. However, in applications where more pressure and heat are involved, Schedule 80 pipes will prove to be a better choice. In addition, most PVC pipes have a maximum pressure rating listed on them to make it easier for you.

Can you use Schedule 40 PVC for hot water?

Ans. The answer is no. As PVC is thermoplastic, at one point, it will degrade and break down after it is heated up. Shown the same thing in the above Sch 40 pipe dimensions table. It just so happens that the Schedule 40 pipe’s maximum handling temperature is 140 F°, around the same temperature when hot water reaches most homes.

Is PVC pipe cheap?

Ans. Yes, PVC pipe is quite cheap, and that’s perhaps its biggest advantage over any other thermoplastic material. However, the prices of specific pipes depend on various factors like thickness, pressure ratings, chemical suitability, etc.

Which Pipe is stronger, PVC or ABS? 

Ans. ABS pipes are stronger than PVC pipes in terms of brute strength and shock resistance. However, PVC steals the show for flexibility. ABS is a better fit for underground applications as it can handle extreme cold and warp if exposed to direct sunlight. For home applications, PVC is a better choice as it is soundproof and muffles the sound of water.

How long is a normal PVC pipe?

Ans. All the PVC pipes sold are within 10 to 20 feet long.

      If your use if specifically for housing needs, than Sch 40 will be just fine.
