ABS and PVC Pipe Fittings Explained

ABS as well as PVC piping are employed within the construction industry. ABS in addition to PVC are generally 2 kinds of plastic-based pipes in addition to fixtures employed in the building industry. Each variety is used throughout limited-pressure applications for example DWV (drain, vent and waste) as well as sewer lines. ABS and PVC styles have got consistent internal areas which are perfect for unimpeded circulation, and also the pipes’ durability as well as substance level of resistance assures much-needed longevity with regard to sewer line installs. The actual pipes can easily endure many years of withering with no sings of deterioration, corrosion or even decay or other kinds of materials degradation.


The actual primary substance within ABS piping along with fixtures is known as a thermoplastic material referred to as acrylonitrile butadiene styrene, or just ABS abbreviated. The pipes possess a foam core, and then the edge of every part of pipe must be fixed under one inch for it to keep resistant against significant pressure. PVC piping, also referred to as CPVC, is constructed from a thermoplastic substance referred to as chlorinated poly-vinyl chloride. The primary structural distinction between both varieties is the fact that ABS as a substance is much more adaptive compared to PVC, and may deform underneath exposure to the sun.


ABS piping is thoroughly employed in DWV purposes, and over ten billion ft of the product has been placed by constructors within commercial and residential constructions. ABS is employed both in ground and also above-ground applications, and may even be mounted outdoors, provided the piping fulfil specified factors. Depending on regional restrictions, outdoor use may need the piping to consist of colours to avoid it from uv radiation or even to be brushed with a water-based latex paint.


PVC piping is best suited to be able to dispense water throughout a variety of temperature ranges. In room temps, the piping possess a four hundred psi pressure rating, at 180 F, pressure rating is actually 100 psi. PVC piping is resistance against most typical residential chemical compounds, and considering that the material doesn’t aid combustion and can’t burn without having a fuel source, it’s employed as an option to conventional steel and copper-based piping within sprinkler installs.

Equally ABS and PVC pipe varieties will be required by regulating bodies to include actual markings on the body. Whether or not the pipes are cut in fairly modest sections, the marks have to be plainly noticeable on the finish; a number of local restrictions require the markings to be present every five feet of pipe span. Together with the manufacturers brand and also trademark, the markings consist of details about compliance to standards, dimensions, variety of resin as well as schedule number. Marks regarding pressure ratings will be incorporated into PVC piping however is absent within ABS piping, whilst a DWV name is incorporated within ABS piping yet omitted within PVC pipes.

The installation of ABS piping is easier when compared with installing PVC pipes, since the former is a one-step procedure whilst the latter consists of two steps. Within PVC set up, a purple primer has to be put on prior to gluing together every joint, if not they will likely split apart in time. Making use of purple primer can be an involved and also tiresome procedure since the substance is extremely viscous and can very easily spread, making the piping appear less than professional. An additional problem with PVC installation is the fact that joint parts have to be held together for five to ten seconds immediately after putting on glue, or else the joints will probably be unfastened; within ABS installation, the actual adhesive functions immediately and therefore the joint doesn’t have to be held together.
