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.

ABS piping was the earliest pipes to become accepted for use with regard to waste materials, drain pipes, and also ventilation systems. ABS piping is excellent to implement because they’re inexpensive and simple to make use of as well as handle, nevertheless in a period of time ABS piping will become fragile and also breakable. Numerous residential areas do not really permit the usage of ABS piping, therefore before you decide to place ABS examine the plumbing code within your local community.

ABS Pipe installation instructions

Items You will Require:

  • ABS pipe
  • ABS fixtures
  • cleaning agent
  • paint primer
  • cement
  • dauber
  • pipe cutter
  • hacksaw or miter saw and box
  • deburring tool

Cut the pipe to the length you need it to be. Work with the deburring tool in order to eliminate any kind of burrs and or rough areas upon the pipe. Do Not Work with Sand paper. Applying sand paper is certainly a typical error several people make, sand paper has a tendency to shave off part of the pipe creating the caliber slighter. This may produce gaps whenever attempting to join up the piping leading to unnecessary leaks.

Work with the cleaning agent, and then the primer, lastly apply cement on each of the connecter pieces, and on the end of the ABS pipe which you are just about to connect. Promptly but very carefully slip the pipe directly into the connector piece and then twist the piping a 1 / 4 turn and then support for thirty seconds to get the cement to dry out.

Thoroughly clean any dirt or surplus cement with a cloth.

Is there a distinction between DWI authorised and WRAS authorised (Water Regulations Advisory Scheme approved) items, and when is it required?

The main requirements required for pipework to be fitted and also in accordance in the united kingdom is the Drinking Water Inspectorate (DWI approved) that’s legal requirement of every distribution and also water treatment pipework, which includes ABS and also PVC pipe along with fittings and also for systems which are given the task of carrying potable water over the stop cock the device must be entirely WRAS (Water Regulations Advisory Scheme) accredited, once again it is required for all ABS and PVC pipe and fixtures.

What’s the shelf-life of Industrial Water Equipments solvent cements, and also what products could it be used in combination with?

Solvent cement is only able to be applied on certain kinds of plastic pipe systems, included in this are both ABS pipe and fittings and also PVC pipe and fittings, however not Industrial Water Equipments clamp saddles or compression fittings. Another type of solvent cement is required for ABS pipe and fittings and PVC pipe and fittings, each of which can be purchased from Industrial Water Equipment. Tins are labeled with a bare minimum shelf-life of two years. Assessments have demonstrated zero degeneration on unopened tins following several years storage, however it hasn’t been possible to ascertain a maximum limit. The actual cements don’t encounter any kind of unseen variations, therefore if the viscosity is OK, the cement will be functional.

What insulating material am i able to make use of on ABS pipework and fittings?

Proper care has to be considered whenever specifying insulating material intended for plastic pipework systems, this is especially significant whenever insulating ABS pipework and fittings. Industrial Water Equipment advises that mineral wool varieties including ‘Rockwool’, Class 1 HT Armaflex or even Phenolic foam types such as ‘Koolphen’ are appropriate, and many types of others really should be avoided except if Industrial Water Equipments technical department has granted prior acceptance.

Am I Able To joint ABS pipework and fittings to PVC-U pipework?

It’s not encouraged to joint 2 unique plastic-type pipework models by way of solvent cementing, however it can be achieved, so long as the ABS pipework and fittings and the PVC pipework and fittings are well suited for the application. Joints have to be created totally in agreement with recommendations. PVC-U solvent cement should be used.

Exactly what pipework method would you suggest with regard to low heat range applications?

ABS pipework stays ductile at temperature ranges as little as -40ºC and it is perfectly suitable for low temperature purposes.

Is it plausible to tap into a live ABS pipework or PVC-U pipework?

Sadly, squeeze off technology formulated for PE mains can’t be applied to ABS pipework or PVC-U pipework. Pipe freezing may happen. You will find in spite of this, specialists who concentrate on this particular work.

Is there a lowest/highest ambient heat range in which I’m able to effectively create solvent weld joint on either ABS or PVC pipework?

Temperatures are not crucial so long as surfaces of the plastic pipework as well as fittings are maintained dry and clean. Even so, for under zero temperature ranges, you need to permit supplemental curing time, because the evaporation rate from the solvent is going to be slowed up.

Can we test out the installation of ABS and PVC pipework and fittings?

Following installing and then permitting the correct drying times, the recommended approach to testing would be to load the pipework (comprising either ABS and PVC pipework and fittings) with water making certain no air pockets reside, and execute a hydrostatic pressure test approximately 1.5 times maximum working pressure or rated pressure of the ABS or PVC system. The actual plastic pipework will be left pressurised for any time period not exceeding beyond one hour.

Could the solvent cement jointing procedure result in toxins inside the pipework? Which could subsequently pass in to the substance the pipework contains?

We’re able to concur that solvent cement jointing (whether with ABS or PVC systems) doesn’t generate toxins within the pipework or conveyed fluid. The actual solvent part of the cement is built to ‘melt’ the pipework surfaces and permit straightforward set up of components, after which it evaporates away totally to leave a completely cold welded joint. IWE’s solvent cements as well as associated products have already been tested and approved for usage with cold potable water systems by WRAS (Water Regulations Advisory Scheme) and may be viewed as fully WRAS approved.

PVC pipe is typically offered in fractional and also ” dimensions, and also according to class, displayed as schedule, example, the majority of potable water pipe is schedule 40. Typical sizes of PVC pipe range from 3/8 ” to 24 ” diameter, and also from DWV (drain, waste, vent) that may be compared to schedule 20, to schedule 80, the heaviest standard generally used. Generally, the greater the schedule number, the thicker the actual walls of the pipe will be, and therefore, the more rigid the actual pipe is going to be.

Schedule 20 or DWV is usually employed for non pressurised or lower pressure plumbing purposes, and is normally the least rigid piping. It is typically employed for irrigation methods, sanitary water flow and drainage as well as venting within building plumbing, and also for building assignments in which overall flexibility is much more essential when compared with structural sturdiness.

Schedule 40 is the normal class domestic plumbing pipe for household as well as industrial potable water services. It offers a burst strength status of around 160 PSI at 72 deg. It will be firmer when compared with schedule 20, and far more suited regarding rigid construction tasks.

Schedule 80 is the heaviest standard PVC pipe class, and is employed regarding applications where by robustness is crucial. The most typical use in construction regarding schedule 80 pipe is within subterranean electrical conduits. It is extremely stiff, and also is appropriate regarding rigid frameworks.

Specialised classes consist of C900, employed for water mains in which pressure may possibly be more than 150 psi, CPVC, that is graded for increased temperatures (also known as hot water pipe), and also cell-core, which has an comparable wall thickness as its counterpart schedule piping however are lighter in weight as well as less costly.

1/2” Plumbing Grade PVC pipe is very adaptable, however is lacking in sturdiness. 1/2” PVC pipe may kink whenever bent. This performs well for light constructions, however will not perform well with respect to anything which requires something to be attached.

3/4” Plumbing Grade PVC pipe is extremely flexible, perfect for just about any kind of task which calls for overall flexibility, particularly green houses, pet agility hoops in addition to various other curved frames. it is also beneficial when elasticity is needed within a project, because it will spring back again to it’s initial shape.

1” Plumbing Grade PVC pipe is marginally flexible, however still relatively rigid. 1” PVC pipe is suitable if a touch of swing is desired within a project, however still demands a strong construction.

1-1/4” Plumbing Grade PVC pipe is the best size with regard to extremely rigid, light-weight assignments. 1-1/4” PVC is ideal for framework. It still provides some modest mobility.

1-1/2” Plumbing Grade PVC pipe is close to as inflexible as any project might demand, besides from using 2” PVC pipe. 1-1/2” is relatively weighty and also can be challenging to work with

2” Plumbing Grade PVC pipe is as strong a pvc pipe as a person may ever require, and also will carry a great volume of weight devoid of bending. It is incredibly heavy and also fairly expensive in relation to other PVC pipe sizes. Even so if your project is demanding an excellent foundation, 2” is ideal.
