Sealing of Joints

Hdpe 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 pipes 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 twin wall corrugated pipe 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 Pipes 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 rigid 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.
D < 200 to 600 mm 
200 < D < 600 to D+400 mm. 
600 < D < 1200 to D+500 mm.

Information about the picture shown above:

Upper class: Uncompressed landfill. (Excluding Road Crossings)
LAYER SHIRT         : Free from hard objects, compressed soil.
LAYER PILLOW: Compacted sand.
Hustler: The distance between the upper elevations of the pipe and the ground (mm) (maximum of 50 cm. Should be)
b: Trench Width (mm)
Y: Cushion layer height (mm)
DN: Pipe outside diameter (mm)
A free flow non-pressure sewer system is concerned. However, they are exposed to external loads for laying underground. Hdpe 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 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.

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 pipes. 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 drain 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.
