Recycling plastics, polyethylene, cellophane and their derivatives - it is not as expensive as troublesome, yielding a small income, especially in the early stages of development.In this connection, wherever you cast eyes, you will see scattered bags, bottles, different parts of household appliances.Though take anything from plastic does not.However, there is one area of production, where the use of this material brings a lot more benefits and requires almost no waste.We are talking about water and sanitary systems.Talk about polypropylene pipes sold under the trademarks "KORSIS" and "Pragma".
Purpose and scope
Polypropylene pipes designed for gravity passes industrial fluids, waste water and storm water, solving the problems of water supply and sewage output.With all these features successfully copes sewer "Pragma" and "KORSIS."Design features much easier to bookmark and operation of pipelines.They are used for both underground and outdoor (land) pads in different regions of the country in different climate latitudes.As the product of the company "Pragma" and tube "KORSIS" specifications, purpose, structure, and appearance (except for coloring) are almost identical, you can view them on a common example.
Key Features
Products is a two-layer pipe made by extrusion (compound layers) of polypropylene with various additives.The inner working layer is smooth, that prevents the formation of blockages.The outer corrugated layer is responsible for protection against mechanical damage during installation and transportation, as well as the earth pressure during operation.Trumpet "KORSIS" has the following specifications:
- diameter - from 110 mm to 1200 mm;
- depth bookmarks - from 1 to 15 m;
- operating pressure - 10 atmospheres;
- weight of one meter - from 1.2 kg to 50 kg;
- ring stiffness - 2-16 kN / m2.
Modifications corrugated pipe "KORSIS»
All pipes with a two-layer shaped wall "KORSIS" available painted in black on the outside pieces of a length of 6 and 12 meters.Inner color series "KORSIS-PRO" light blue.The product is characterized by high ring stiffness - 16 units (a measure of heart failure).This allows stacking a maximum depth of 15 meters.The indicator of heart failure as a function of diameter, wall thickness and structure in the pipes may be 2, 4, 6, 8, 10, 16 and 24 kN / m2.The lowest - a series of tubes IVF made from recycled material.
Pipes "KORSIS", technical specifications which are adapted specifically for exterior styling, produced a series of CBT (spiralnovitye).Exterior color - black, inside - white.A series of "iso-KORSIS" specially designed for operation at low temperatures.Another pipe "KORSIS 'specifications is the maximum increase (diameter, wall thickness, ring stiffness).It is marketed under the PLUS series.The diameter of such pipes - 2400 mm.Similar properties have a series of ARM and SVT.Always when choosing corrugated polypropylene pipes guided by the indicator ring stiffness.It is better to buy a series with improved performance.
Piping
As with any other construction of the pipeline, you must first dig a trench, then make a bed of sand.Only then is the pipe "KORSIS."Technical characteristics of this type of pipe arrangement requires not only a sand cushion, but also the entire body filling the pipe with fine sand.It is necessary for the construction of the corrugated outer layer.Thus, the entire load is distributed directly to the ribs.
to dock There are two types of installation: thimble and welding.Connecting via the clutch occurs as follows: first, one tube put on the sealing ring (depending on the diameter of the first or second slot).Then we sit down collar.Now the ring is worn on the second tube and insert it into the first clutch.
Technique joining by welding is no different from any other type of connection of polymer products.Pipes' KORSIS "large diameters are available with socket.Its length is from 97 to 433 mm.With welding machine heating tip and end with a bell, and then inserting them into each other, we have a strong and reliable joint.
advantage of corrugated pipes
On the merits of polypropylene corrugated pipes can talk a lot.Here, both the speed and ease of operation, and material savings plus human resources.Increased performance and compliance with environmental requirements are also pluses.But the main advantage of the pipe "KORSIS" - technical specifications, you can use it in unstable soils in permafrost conditions.A Double Arch form corrugated surface is capable of withstanding high loads in any adverse temperatures.
