Abs Duct For A Dryer

Being toll-efficient and relatively tardily to hold makes ABS an appealing pick for a dryer’second ductwork. If ABS were to meets the standards of the International Residential Code (IRC), it could live a potential option to metallic ducts.

As amongst any big appliance with a heat source, safe is beginning and first off. While really useful under different circumstances, ABS could try out to be a rattling unsafe option to metallic ductwork.

ABS is not permitted for purpose every bit dryer ducts. Dryer ducts accept to be made from metallic and take a flaming spread index below 200. ABS is a thermoplastic amongst a flame spread index between 200 too 275. Using ABS is extremely unsafe equally it promotes lint build-ups in addition to atmospheric condition ideal for the lint to catch alight.

Is Static Build-upwards a Problem amongst ABS?

Acrylonitrile Butadiene Styrene, or ABS for brusque, is a especial type of thermoplastic.

A large effect when assessing which materials are adept for ducting dryers is how prone they are to static construct-upward.

Dryer ducts carry and collect lint, which is highly flammable. Add to this the rut of the exhausted dryer air and you accept yourself a potentially dangerous set-upwardly.

If the material of the ducts generated static accuse readily, so not alone would lint collect much more easily, past the electrical accuse could make sparks together with set the lint on fire.

ABS has low electrical electrical conductivity. Oftentimes this textile is as well used as an electric insulator too protects wires. With that existence said, it’s unlikely that yous’d meet a static construct-upward job using ABS.

PVC is another common plastic cloth used for plumbing and ventilation. However, PVC pipes permit for static build-upward. This static construct-upwardly tin be real unsafe as it tin can atomic number 82 to fires from the ignition of the flammable dryer lint. As such, PVC is a prohibited dryer duct material.

Can ABS Withstand Dryer Temperatures?

Depending on the make and model of your dryer, the highest temperature it volition achieve is about 135 °F. ABS pipes or ducts tin withstand temperatures equally hot every bit near 180 °F, then ABS should be able to withstand the temperatures of your dryer.

While a plastic ABS duct could withstand the temperatures of well-nigh dryers, at that place’second all the same the potential for the plastic to melt inward certain areas exposed to higher oestrus. Not entirely would this ruin the ductwork merely also would lead to even more lint build-upward inwards the dips together with hollows created inward the melting plastic.

Dryer Ducting Must Be Metal

In Section M1502.4.1, the IRC states that dryer ducts must live constructed of metallic.

The IRC provides further details near the material (smoothen inner surface as well as a specific thickness), but fifty-fifty if ABS meets these requirements, the rattling fact that dryer ducts must be made from metallic agency that ABS is not an selection.

The argue behind these regulations for a dryer’second duct is primarily for safe. Metal does non have the same static construct-upwardly issues as plastic. A polish interior volition as well assistance to avoid the build-upward of lint.

The thickness of the metallic protects against the high temperatures of the dryer. While the minimum requirement is real thin, this nevertheless ensures that the integrity of the duct is maintained together with the heat isn’t existence transferred to areas outside the ductwork also much. Insulation tin too assistance amongst this.

ABS Flame Spread Index Is Too High

Flame spread index (FSI) is used to mensurate the surface burning characteristics of building material and indicates how good a fire volition spread in or on a certain fabric. As such, FSI is a rattling of import mensuration used to ensure safety inwards buildings.

For dryers, which combine oestrus and flammable material each time they are used, it is vital to adhere to the recommended FSI.

In Section M1601.i.1, the IRC states that duct systems will be constructed of material with an FSI no greater than 200. ABS has a FSI that tin can range from 200 to 275, which is some other footing on which it cannot live used equally dryer duct cloth.

ABS Cannot Be Used for Dryer Ducts

While many of the IRC’second requirements regarding a dryer’s ductwork are met by ABS ducts, they should non live used because not all the requirements are met.

Although you might be tempted to effort it because ABS is then cost-effective, y'all take to recollect that the rules are non merely in that location to brand your life hard or even but to standardize aspects of structure for easy regulation.

The prohibition of dryer duct materials like ABS is based on safety.

If y'all needed only one more reason to avoid ABS dryer ducts, consider the fact that they are relatively flexible, which mightiness become an result when it comes to installing backdraft dampers. Backdraft dampers are both mandatory according to the code and vital to foreclose rut loss through the dryer ducts together with common cold drafts coming through the dryer vents.
