← Back to ABS PipeABS pipe is extruded from acrylonitrile butadiene styrene, a terpolymer of acrylonitrile, butadiene and styrene. The acrylonitrile fraction gives chemical and heat resistance, the butadiene fraction gives toughness and impact strength at low temperature, and the styrene fraction gives the rigid, smooth, easily machined surface that makes the pipe straightforward to cut and joint. The result is a rigid thermoplastic pipe that behaves like a light metal pipe on site but never rusts.
ABS piping is a long-established choice in drainage, soil and waste systems, and is also widely used in water and wastewater treatment plants, aeration headers, sampling lines, aquaculture and marine service, and chemical-duty piping where dilute acids, alkalis and salt solutions would attack metal. Because the material is electrically non-conductive and carries no free metal, it is immune to galvanic corrosion and needs no lining, coating or cathodic protection.
Nuoweisen supplies ABS pipe to order, together with the matching fitting range. Nominal size, outside diameter, wall thickness, pressure rating and colour are agreed in writing with the quotation, so the pipe you receive matches the duty you specified rather than a generic catalogue line.
The standard product is a solid-wall extruded pipe in uniform lengths, with a bore that stays smooth over the whole service life — low friction loss, no scale build-up and no tuberculation to reduce the flow area. Where a project calls for it, the pipe can be produced with a socket end formed for cement or ring-joint connection, or supplied as plain-ended pipe for site fabrication. Cellular-core and co-extruded constructions exist in the ABS piping family; if your specification requires one, state it on the enquiry and we will confirm availability before quoting.
Elbows, tees, couplings, reducers, sockets, caps and transition pieces are produced in the same material as the pipe, so the whole line has the same corrosion behaviour and the same thermal expansion. Fittings are confirmed item by item against the order; send a line list or an isometric and we will price it as a set.
ABS pipe is light enough for one or two people to handle at normal diameters, which shortens installation and reduces lifting equipment. Like all thermoplastics it expands and contracts with temperature change, so long straight runs should be designed with expansion provision and with supports that allow axial movement rather than clamping the pipe rigidly. Above-ground runs in prolonged direct sunlight should also be considered at the design stage, because long-term UV exposure is the one environmental factor that affects unpainted ABS.
The values below are typical published figures for ABS polymer. They describe the material family, not a guaranteed batch value, and they are not a substitute for the pipe data sheet issued with the quotation.
| Property | Typical value | Remark |
|---|---|---|
| Density | 1.04 – 1.07 g/cm³ | Roughly one-seventh the density of steel |
| Water absorption | ≤ 0.45 % at 23 °C | Low, so dimensions stay stable in wet service |
| Electrical behaviour | Non-conductive | No galvanic corrosion; no cathodic protection needed |
| Chemical behaviour | Resistant to water, wastewater, seawater, dilute acids and alkalis | Confirm concentrated or aggressive media with our team before ordering |
| Impact behaviour | Good impact strength retained at low temperature | A key reason ABS is chosen over rigid PVC in cold service |
| Service temperature | On request | Confirm the operating temperature range of the line |
| Pressure rating | On request | Confirm the working pressure and required safety factor |
ABS pipe is produced against several national and international systems — for example the ASTM drain, waste and vent series, EN 1455 for soil and waste, and the metric DIN series for industrial piping. The dimensional and pressure tables differ between them, so a size quoted as one nominal diameter is not automatically interchangeable with another system. We therefore quote dimensions against the standard and duty you specify rather than publishing a single generic table.

No dimensional, pressure or temperature figure is published on this page because ABS pipe is made to several different systems. Send the size, working pressure, temperature and medium and we will return a written figure that matches your specification.
To quote accurately we need the following. The more of it you can send, the faster the quotation and the smaller the risk of a mismatch on site.
This reference is compiled from published material data for ABS polymer and from general good practice for thermoplastic piping in water and wastewater service. Typical material values are given for guidance only; dimensional, pressure and temperature figures for the pipe we supply are issued in writing with the quotation and confirmed against the ordered specification. Where a figure on this page is not confirmed for your duty it is marked On request rather than estimated.
