Corrugated Pipe and Fittings

Corrugated pipes used for many years in the leading European countries, the US and Japan; having a high compressive strength and are serrated outer tube having rounded appearance. EN 13476-1 and DIN 16961-16566 made according to standard corrugated pipe production along with developing technologies in all new projects now being used intensively. Corrugated pipes  usually are used to transport the waste water and sewage is one of the biggest reasons for preferring the high strength and economy. Rib system on the outer surface of the corrugated pipe is used to improve resistance to external pressure pipe. Referring to other plastic pipes chemical resistance is one of the most important characteristics of corrugated tubes, our pipe is resistant to abrasion and high chemical resistance.

Corrugated Pipe Application Area:

• Infrastructure application
• In the irrigation system
• Sewer lines and residential connections
• Rainwater
• Industrial Applications
• Drainage systems
• Treatment plants
• Gravity is used in water transport system.

Characteristics of Corrugated Pipe

Corrugated Pipes; high strength due to the high rib strength, the corrosion resistance due to polyethylene, the full sealing, 50-year life, wear-resistant organic composition, smooth inner surface, easily transportable and are pipes laid in a short time.

If we examine substances;

• Corrugated Pipe Provides excellent resistance to high resistance abrasion and chemicals.
• Thanks to exterior design and ribs which are resistant to heavy loads. Corrugated Pipe Impact is a tube with the highest strength against load and ground movement.
• Liquefaction of the soil beneath the underground water pipes, known in history against the resulting strain and stress is the strength of the pipe.
• Corrugated pipes are lightweight, easily transportable because of this structure is no need for special equipment and manpower, with up to a certain diameter.
• Corrugated Pipe it has an Easy bonding method, they are conjugating the vet to muffle the gasket sealing sleeve.
• It has a sealing up to 0.5 bar pressure.
• Corrugated Pipe provides repair and maintenance.
• Interior surfaces can be produced in any color.
• Polyethylene corrugated pipes feature should fulfill its function for many years without being affected by environmental conditions.Polyethylene is one of the most important feature; Corrugated pipe land is flexible to move even against earthquakes. They remain wear is dominant against chemical raw material. Friction losses are minimized and will not corrode. It is economical; transportation, labor and time savings due to years of life can continue to seamlessly Corrugated pipes have been an economical and indispensable option.

 Advantages of Corrugated Pipes:

Corrugated Pipe of fabricaton and spiral wound structure because it provides more durable and high quality production. Due to the smooth flow rate for the high corrugated pipes allows the transmission fluid in the smaller pipe diameter.

• Also because of its low coefficient of friction does not create sediment and debris in the corrugated Pipe.
• Crack and impact resistance is excellent.
• Has the shape of multiple coupling facilitates project.
• On-site due to the presence of carbon black are not affected by UV rays.
• Consolidation project implementation will be done in place.
• Inner part made up for the production of polyethylene and shows high resistance to abrasion.
• Because its high strength it is Easy to carry ,laid quickly, Maintenance, transport, labor and installation are economical. Operating costs are low. Other corrugated pipe laying in the cost of the lowest.

Sealing of joints:

Corrugated Pipe trunking operation is done in two ways, as we will explain them below.

These are: Muffle the binding process with the welded or gasketed. System structure of the joints should not leak.

Sealing issue is actually a very important issue that needs to be deducted and should be the top priority for us.

Because the leak takes place will be interfering in our place under water leaking sewage pipes and will begin to disappear from our underground wealth.

 Corrugated Pipe Raw Material and Specifications:

Sewer pipes is a product produced from polypropylene and polyethylene materials within the Polyolefin group. Produced up to Ø450 mm diameter corrugated pipe; polyethylene and polypropylene manufactured from raw materials, coiled corrugated pipe are manufactured from polyethylene. More is preferred because the same wall thickness polypropylene ring strength value is higher. The rolling method with Ø500 mm and pipe diameter are produced on. Divided into three main groups according to their percent Polyethylene density and crystalline structure;

• Low density polyethylene raw material (LDPE)
• Medium density polyethylene raw materials (MDPE)
• High density polyethylene raw materials (HDPE)

High density polyethylene is most closely chemically pure polyethylene. HDPE has very good chemical resistance to many chemicals and solvents.

The most preferred that the products associated with detailed information about Polyethylene HDPE Pipe and Fittings page, RAW MATERIAL OF POLYETHYLENE find all the details about the polyethylene under PIPE title and the formation of high performance compared to other raw materials species in their field and as the economy as due to the long lasting strength until you can find a detailed information about the duration.

1st type : Polypropylene homopolymer: molecules produced from propylene and ethylene are no contributions. Therefore, due to the soft bag with soft polypropylene homopolymer used in the production of materials such as plastic bags.

2nd type: Bloco Polypropylene Copolymer: Ethylene contribution of (3%), are raw materials. Mukavvemet the temperature of the raw materials is used in the production of the plastic pipe for use only in cold water lines is lower.

3rd type: Polypropylene Random Copolymer: Again, that is a raw material ethylene contribution. The amount of ethylene is between 3-7%. 4 Application areas are places where there is high pressure and temperature values much higher. All details relating to polypropylene raw material propylene molecule derived from substances naphte end obtain larger molecules by adding end so obtained by polymerization of a white material, the formation of the information regards the time until the use PPRC Pipe and the Fittings page “polypropylene feedstock and PROPERTIES “you will find under.

Corrugated Pipe Handling and Transportation

Corrugated pipe is lightweight and easy to be moved at the same time be resistant to shocks to most important cases in transportation and warehousing. Therefore there is no leakage during transportation and storage to the process is not mentioned. Putting because it is intertwined with the light can be storage and shipping.

Other Of potential problems to live in one of the pipes in the storage area cleaning is important Corrugated Pipes. Sharp stones and should be free of rocks in the stock area.

In -Shipping tool should not still be kept clean and sharp stones and hard objects. During the transport process it should not be covered with hard objects. Corrugated pipes as the sun’s rays should be kept in an low and maintained environment  even in areas covered possible. Possible to make long-term storage in such an environment.

Corrugated Pipe in a completely closed environment and warm weather should not be kept for longer term. Be careful not to muffle the bell on the part of the pipe during storage. Stacking because they are flammable raw materials should be observed while performing safety regulations. Shipping time increased with altitude during installation tool especially made excessive stretching should be avoided while connecting to damage the pipe. Which will be held in the transport and construction equipment should not be used suspension rope sharp.

If the installation is done with folklift if your feet should be kept high. Should not be hit hardly.

Pipes should not be riged while transferring it from one place to other. Infact it should be rolled on the ground so that it does not get affected.

Corrugated Pipe Trench Cross Section

Trench Width: Paying attention to soil conditions in the area size is required to compress the assembly and filler material is sufficient. Standard for Corrugated Pipe trench widths are set forth in the table below.

A free flow non-pressure sewer system is concerned. However, they are exposed to external loads for laying underground. Corrugated pipes are designed to withstand such loads respectively. Therefore, the influence of external loads such as ground and traffic loads gains importance.

Some rules to be followed in laying pipes under the soil made the waste water sewerage system implementation is concerned.

Corrugated pipes and fittings excavated channel in order to give many years of trouble-free service held in underground applications; channel around the filling pipe must be made of compression in layers not to be poor. In particular to be filled with the filler pipe gold it is very important.

If the filling process is best done properly, traffic and soil load of pipe from the pipe partially fill transfered, it performs during the life of the mission smoothly. Due to space compression will occur if the pipe is well done, exposure to crash risk can not be transferred to other forces that may occur on the load.

 Corrugated Pipes Joining Methods:

The methods used in the bonding process of the corrugated pipe:

– Muffle Sealed

– Sealed Sleeve

– Electrofusion Welding is Method.

Sealing method, by fitting the groove on the outer surface of pipe joints is a method by treating the appropriate inserts.

 Electrofusion Welding Method:

According to the diameter and length of each different, some will be merged with the pipe made of polyethylene tape coated with EF and EF is implemented using copper wire welding machine. Centering on the inside with a piece of pipe to be made in fixing the merge process is ready to EFE sources. Belt use EF to clean the surface of the pipes will be welded later before proceeding with the winding process is performed and the ribs are fixed to the pipe and coupling place between them via a special apparatus.

After allowed to cool EF supply corrugated pipe. With regard to sealing the welded manually required machine from the pipe inner surface. Thus, the seal is eliminated danger. Another important note regarding the EF welding; The settings of the EF welding machine according to the pipe diameter. Thus, the seal is eliminated danger. Another important note regarding the EF welding; The settings of the EF welding machine according to the pipe diameter. This coupling method is normally used in making corrugated pipe used even at 4 bar under pressure of 0.5 bar. Thus, the increase in pressure encountered in rainfall has turned into flood without damage from leaking pipes and welds will continue to work.
