Material pipe pressure and gravity sewers

Material pipe pressure and gravity sewer

Driving apartment building sewage is quite simple: the natural flow on the non-pressure pipes to the main collector and pumping sewage powerful pumps to collection points and recovery.Otvodnaja sewerage system of a private house is built on the same principle.But there are some nuances.

With a small amount of wastewater big difference in choosing the material of the pipeline with natural and forced runoff there.Well, if your site is on a slope, then distributing non-pressure sewage pipes and septic tank installation space uniquely determined.If drains have to drive to the collector under pressure, installing a reinforced pressure valve becomes inevitable.Choosing the material.

1. Cast iron pipes .Details of the characteristics of these products you can find on our site.In an urban setting - more classic for cottage construction - too expensive, inconvenient to install and operate.At the same mechanical properties for pressure pipe systems in these best.
2. PVC pipes for sewerage pressure .Lite version of the economy - the class.Pros: fast installation, which can be done with his own hands, a wide assortment of fittings, low price.However, even in depressurised embodiment PVC pipes have a whole bunch of flaws.Low plasticity, heat resistance and brittleness of the material can lead to cracking of PVC products in seasonal strains of soil;rubber seals fittings and joints lose their elasticity, and need to be replaced quickly.Find and fix leaks are very troublesome.
3. reinforced concrete and asbestos cement .These materials are used in the private housing construction is extremely rare.The cross sections of the pipe and the weight suitable for collectors and pressurized sewer main high-pressure systems, and in suburban areas, they will look ridiculous.

Pressure sewer pipes made of polyethylene

PE high and low pressure appeared in piping systems for different purposes are relatively recent, but is gaining construction markets.The reasons lie on the surface:

• high ductility, mechanical shear stability;
• corrosion and hydraulic resistance almost like iron;
• low proportion (1 rm PE100 diameter 40 mm and weighs 0.5 kg), easy to install the sewer discharge circuit is the same as that of PVC pipe;
• reasonable price: meter pipe 11-16 atm d = 50 on average costs 54 rubles;
• comprehensive assortment of fittings, allowing fans breeding scheme of any complexity.

wall thickness of PE100 pressure sewer pipes ranging in the range of 3-70 mm, that gravity performance even excessively, but guarantees a long (up to 30 years) service life of complex wastewater, so the choice between PVC and polyethylene, we recommend to do for the benefit oflatter.

Double layer corrugated pipes for non-pressure sewage

next step in the development of technology for producing light, reliable and easy-to-install piping components.Profiling the outer bypass has reduced the consumption of materials of plastic products, simultaneously raising the ring stiffness.Sandwich of molded corrugated outer and inner layer with excellent hydraulic properties ideal for storm drains and natural household.Add the impact strength, low coefficient of thermal expansion, high tensile strength and get an almost perfect design.

Mounted such pipes in two ways:

• through special couplings and O-rings;
• by butt welding.

Our recommendation: to design and arrangement of the sewage system in your home, read the technical characteristics of pressure and gravity pipes, submitted by manufacturers.
