• All of the Aysan corrugated pipes are self-muffed and they help save time, labor and gasket, and at the same time they decrease the risk of leaking out % 50 in comparison with pipes which are connected with muffs.
• External layer of Aysan corrugated pipesare produced from black colored material which is resistant UV lights and impacts.
• Their resistance against to outer loads is very superior.
• Thanks to their low weight,they are easy to be transported and to be used.
• They are easy to be dispatched and to be stocked.
• Their installation, their repair and their maintenance is very simple.
• They are more economical than equivalent products.
• They help work without any wastage.
• They are resistant against chemicals.
• They are not affected by conditions of nature and atmosphere.
• Self-muffed pipes can be connected each other without need of any attachments.

• Wire, wire rope, chain or rope made of artificial fibers should not be used while the pipes are loaded on vehicles, transferred or unloaded from one vehicle to another.
• Pipes should not be lifted abruptly, loading or unloading should be done by throwing or dropping.
• In case of necessity, it should be lowered carefully on soft cushions such as old truck tires, and should not be lowered on hard floors with stones or gravel.
• Corrugated pipes should not be dragged during loading and unloading, as they are more prone to abrasion and scratching.
• Nails, pointed protrusions, etc. on the floors where pipes will be placed in vehicles. should not exist.
• The ends of the pipes must be protected so that they are not damaged by impacts and impacts.
• Appropriate vehicles (forklifts, tow trucks, etc.) should be used for the areas where the pipes will be loaded.
• Pipes should not be transported by rolling or dragging.

• Pipes brought to the storage area should be carefully examined, if there is damage to the pipe, that part should be cut.
• Corrugated pipes can be stored open top. however, pipes that will be exposed to sunlight for a long time should be stored covered in order not to be damaged.
• Pipes should be stored on soft ground, flat ground or preferably on horizontal racks made of timber.
• Pipes placed on top of each other should be stacked in such a way that their bells are not damaged and remain free or axially in opposite directions.
• Stacking height will not exceed 2.5 meters and max. It should not exceed 2% reduction.
• Measures must be taken to prevent water, soil, mud and dirt from entering the pipes during storage. If such contamination cannot be prevented, the pipes must be cleaned before they are installed.

There is a non-pressurized gravity (free) flow in sewage systems. But since they are laid underground, they are exposed to external loads. For this reason, the effect of external loads such as soil and traffic load becomes very important. Corrugated pipes are designed to be resistant to such loads.

There are some laying rules that must be followed in pipe applications made under the ground in waste water sewage systems. In order for the corrugated pipes and fittings to serve for many years without any problems, in underground applications made by digging the channel, compaction should be made layer by layer so that there is no weak area around the pipes while the channel is being filled.

Özellikle boru altının dolgu malzemesi ile doldurulması çok önemlidir. Dolgu işlemi şartnameye uygun şekilde iyice sıkıştırılarak yapıldığı takdirde, boruya gelen trafik ve toprak yükü kısmen dolguya aktarılacağından boru ömrü boyunca görevini sorunsuzca yerine getirir. Sıkıştırma iyi yapılmadığı taktirde oluşacak boşluklardan dolayı boru, maruz kaldığı yükü, üstündeki diğer kuvvetlere aktaramayacağı için çökme riski oluşabilir.

Dolgu Malzemesi: 0 ila 20 mm çaplı tanelerden oluşan ve en fazla %20 nem ihtiva eden sıkıştırılmaya uygun malzeme kullanılmalıdır.

• Pipes should be placed in a trench 50 cm wider than the pipe diameter, depending on the diameter to be applied.
• The trench floor should not be uneven, except for the slope to be applied, and there should be no coarse stones or gravel on the ground.
• Pipes placed on the ground should have equal margins and liner should be made with fine sand.
• The top cover layer to be applied on the pipe is min. It should be 30 cm. The top cover layer should be fine soft sand.
• The sand used in the liner should be suitable for compaction, containing 20% ​​moisture.
• Pipe top level should be at least 100 cm depending on the traffic load to be applied. After the top cover layer, it should be completed as natural fill and soil surface, respectively.
• Wrong liner, cushion layer and top filling should be done carefully and correctly as it will cause problems such as collapse and breakage in the pipe during use.
• Gaskets used in pipe joints are always the second gasket socket on the socket for Aysan Plastik production. For Ø400mm corrugated and above diameters, the first gap is the gasket slot, the second wider gap is the gasket gap. Therefore, for Ø400mm corrugated and above diameters; gaskets must be installed in the third space on the socket.
• Concentrated chemicals (acid, base) that will corrode the pipe or hot water exceeding 80°C should not be passed through the pipe. The material should be used.
