What is Cellcore PVC?

There are different types of piping used, and one style commonly used is called 'Cellular-Core” PVC. This type of piping differs from solid PVC or ABS as it has a core built into the walls of the pipe. This makes the piping cheaper and lighter, but slightly less rigid than it's solid counterpart.

Correspondingly, what is Cellcore PVC pipe?

PVC Schedule 40 Foam Core Pipe is for drain, waste and vent purposes only. It is used in gravity fed waste elimination systems. It is for Non-Pressure systems where temperatures will not exceed 140 degrees F. PVC Schedule 40 Foam Core is lightweight, non-toxic and easy to install.

Subsequently, question is, what is solid core PVC? PVC Schedule 40 Pipe is dual marked and can be used in DWV and pressure applications. Gradual sloping fittings are used for DWV applications. Sharply angled pressure fittings must be used for pressure. It is easy to install and has better sound deadening qualities than PVC Schedule 40 Foam Core and ABS Foam Core.

In this regard, what is the difference between cellular and solid core PVC?

The inside and outside walls are solid PVC, while the inner core is cellular (or foamed) PVC, a material that includes tiny bubbles of entrained air. For pipe manufacturers, the main advantage of cellular-core PVC is lower cost, since it requires less resin to make than solid pipe.

What is the difference between PVC DWV and Schedule 40?

DWV parts look very similar to standard white schedule 40 PVC pipe and fittings. The only real difference is that DWV PVC is not made to handle pressurized uses like schedule 40 parts are. Instead, DWV pipe and fittings are made to handle a different class of uses – Drain, Waste, and Vent (hence the name DWV).

Which is stronger ABS or PVC?

Strengths & Weaknesses of Plastic Pipes

For example, PVC is more flexible, 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. PVC is thought to be better at muffling the sound of running water.

What is Cellcore?

225mm Cellcore HX S is a product specially designed to provide foundation protection from ground heave effects when installed under reinforced concrete floor slabs. It is consisted of specially moulded hexagonal cellular expended polystyrene, available in a number of different depths and grades.

What is foam core PVC pipe used for?

PVC Schedule 40 Foam Core pipe is for drain, waste and vent purposes only. It is used in gravity fed waste elimination systems. It is for non-pressure systems where temperatures will not exceed 140° F. PVC Schedule 40 Foam Core is lightweight, non-toxic and easy to install.

Can you bury foam core pipe?

Foam core is meant to be buried. It's not going to collapse but it isn't pressure rated. What it won't do is crack as easily when buried. It's made for drain waste and vent situations in place of ABS.

What is DWV pipe?

In modern plumbing, a drain-waste-vent (or DWV) is part of a system that allows air to enter a plumbing system to maintain proper air pressure to enable the removal of sewage and greywater from a dwelling. Waste is produced at fixtures such as toilets, sinks, and showers.

Why is the use of CPVC plumbing recommended over PVC piping in homes?

CPVC is stronger, more corrosion resistant, and more flexible than PVC. It also withstands higher temperatures than regular PVC. Most current Plumbing Codes will not allow PVC for hot water supply but will allow CPVC. PVC can be used in all Waste Water and Drain applications.

What is cell core pipe?

There are different types of piping used, and one style commonly used is called 'Cellular-Core” PVC. This type of piping differs from solid PVC or ABS as it has a core built into the walls of the pipe. This makes the piping cheaper and lighter, but slightly less rigid than it's solid counterpart.

What schedule is ABS pipe?

Uses & Applications

ABS pipe is sold in 10' and 20' lengths, plus 12' lengths in Canada. ABS pipe is available in solid-wall and cellular-core construction in Schedule 40 dimensions.

Is PVC allowed in return air plenum?

Fact: PVC should not be installed in a plenum. It is classified as a combustible material per ASTM E 136. Fact: Cast iron is a non-combustible product, which can be installed in a return air plenum.

Is PVC pipe flammable?

PVC is highly flammable, and when burned in waste heaps or in accidental fires, PVC off-gases toxic fumes, dioxins, and hazardous chlorine gas.

Is PVC fire rated?

PVC is a naturally fire resistant plastic, as it has 56.8% more chlorine than general-purpose plastics. For flexible PVC products, the plasticizers that add elasticity in most instances detract from its conflict to fire.

Can you bury cellular core PVC?

Flexible piping systems like ABS or PVC have less structural strength than rigid metallic piping systems, which is an important consideration when designing systems buried in unstable soil. Per the standard, cellular core pipe is not permitted to be used in this application due to its reduced pipe stiffness.

Can you use PVC in commercial buildings?

Plastic pipe can only be used in DWV systems in residential buildings up to five stories high. In commercial construction, plastic pipe is prohibited in all applications. However, unlike New York City and Chicago, it allows plastic pipe in commercial construction within the two-story limitation.

What is Schedule 40 PVC pipe?

PVC Schedule 40 Pipe. PVC Schedule 40 pipe is used for drainage and lower pressure water flow applications. Schedule 40 PVC pipe can handle up to 140 degrees F in temperature. Pipe lengths come in standard 10' or 20' sections.

What is plenum rated pipe?

Subject: Plastic Pipe in Return Plenum. PVC, like all plastics, is classified as a combustible material per ASTM E 136. PVC has low flame spread, but smoke developed ratings may be as high as 900, so PVC will not pass the 25/50 criteria of the ASTM E 84 test and may not be installed in plenum spaces.

How do I know if my PVC is schedule 40?

The wall thickness of a PVC pipe or fitting determines its schedule. The thickness also correlates with the amount of pounds per square inch (PSI) that the pipe or fitting can handle. Schedule 40 PVC is usually white in color and has thinner walls, thus can handle less pressure than it's counterpart.

Can CPVC be used in a plenum?

Also, CPVC plumbing pipe is safe for installation in return air plenums; however, the installation must be approved by the local jurisdiction. Even though CPVC is considered a combustible material it will not burn without a significant external flame source.
