How to choose a material for sewer pipe production?
Before choosing a material for sewer pipe production, keep the following aspects in mind:
a. Corrosion resistance: Sewers transport wastewater, which contains gases such as hydrogen sulphide (H2S). When this gas comes into touch with moisture, it can turn into sulphuric acid. The development of acids can cause sewer pipe corrosion. As a result, choosing a corrosion-resistant material is critical for a pipe's long life.
b. Abrasion resistance: Sewage contains a lot of suspended materials, some of which are inorganic substances like sand or grit. Internal wear and tear of sewer pipes can be caused by these particles travelling at high speeds. This abrasion can diminish pipe thickness and reduce sewer hydraulic performance by roughening the internal surface.
c. Durability and strength: The sewer pipe should be able to withstand all of the forces that are expected to be applied to it. Sewers are subjected to significant external loads of backfill material and, if applicable, traffic loads. They are not exposed to water's internal pressure. A sufficient wall thickness of pipe or reinforcement is required to safely sustain external loads without failure. Furthermore, the material chosen should be long-lasting and resistant to natural weathering to ensure that the pipe lasts as long as possible.
d. Material weight: The sewage material chosen should have a lower specific weight, resulting in a lighter pipe. Handling and transporting the lightweight pipes is a breeze.
e.Imperviousness to avoid: Sewage seeps from the sewer into the surrounding area. The pipe material should be impervious.
f. Cost and economy: To make the sewerage scheme cost effective, sewer should be less expensive.
Materials for Sewers
1: Asbestos Cement Sewers: Asbestos fibres, silica, and cement are mixed together to make these. To act as reinforcement, asbestos fibres are extensively mixed with cement. These pipes are available in internal diameters ranging from 10 to 100 cm and lengths up to 4.0 metres.
2: Cast Iron Sewers: These pipes are more durable and can take more tensile, compressive, and bending pressures. These, however, are pricey. Outfall sewers, rising mains of pumping stations, and inverted syphons, where pipes are under pressure, are all made of cast iron pipes. These are also suited for sewers with a large volume of traffic, such as those beneath railways and motorways. They're utilised to carry people over piers in low-lying places. To avoid groundwater contamination, they create a 100 percent leak-proof sewer line. They have a lower corrosion resistance.
3. Plastic sewers (PVC pipes): Plastic is a relatively new material for sewer pipes. These are utilised in the house for internal drainage. These are utilised in drainage operations and come in sizes ranging from 75 to 315 mm exterior diameter. Internally, they have a smooth surface. Additional benefits include corrosion resistance, light weight pipe, cost-effective laying, jointing, and maintenance, tough and rigid pipe, and ease of production and transport of these pipes.
4. Lead Sewers: They're smooth and silky, and they can take on unusual shapes.This pipe has the potential to withstand sulphide corrosion, but it is highly expensive.
Sewer Pipes come in a variety of shapes
Sewers are circular pipelines that are placed below ground level and slope constantly towards the outfall. These are made to flow with the help of gravity. Other than circular shapes are sometimes employed. Sewers can also be made in the following shapes:
a. Sewer in the shape of an egg;
b. Sewer in the shape of a horseshoe;
c. Sewer with a parabolic shape;
d. Section with a semi-elliptical shape;
e. Section with a rectangular shape;
f. Section in the shape of a U;
g. Sewer with a semi-circular form;
h. Sewer with a basket handle.
