HDPE Poly Pipe and HDPE Pipe Suppliers in Saudi Arabia

HDPE poly pipe is our company's main product, which is produced by the production line of Haili factory. At present, HDPE poly pipe is mainly exported to the Middle East and Southeast Asia, and most of the customers are local agents or suppliers. Haili's factory has been built for many years, and the production efficiency is also very high. We can accept customized products, as long as you send us the parameters of the products you need, we will produce products with the highest efficiency, and we must guarantee product quality.

HDPE poly pipe is closely related to municipal engineering. This article will also introduce methods for improving the construction quality of municipal water supply and drainage.

How to make HDPE poly pipe?

To make pipe lengths, HDPE resin is heated and extruded through a die, which determines the diameter of the pipeline. The wall thickness of the pipe is determined by a combination of the size of the die, the speed of the screw, and the speed of the haul-off tractor. Polyethylene pipe is usually black in color due to the addition of 3-5% of carbon black being added to the clear polyethylene material. The addition of carbon black creates a product that is UV light resistant. Other colors are available but are less common. Colored or striped HDPE pipe is usually 90-95% black material, with just a colored skin or stripe on the outside 5%. Find more hdpe poly pipes HDPE Pipe Suppliers in Saudi Arabia.

HDPE Poly Pipe with Blue stripes

A different die is used for a striped HDPE pipe, which has small channels that the colored material runs through, just before it is pushed through the die. This means the stripes are formed as an integral part of the pipe and are not likely to separate from the main pipe body. Co-extruded, or co-ex HDPE pipe, has a second extrusion screw that adds an extra skin of color around the black HDPE pipe, this allows the pipe to be colored on the outside, for the identification or thermal cooling requirements.

Discussion on the method of improving the construction quality of municipal water supply and drainage

Water supply and drainage engineering is the foundation and key to the normal operation of urban functions, and it is also the main premise and foundation of urbanization development. The quality of drainage pipeline engineering is the main way to affect the urban drainage function and urban use function, and it also affects the main basis for the rational and orderly development of urban traffic problems. It is also a direct way of urban environmental protection and urban safety. Therefore, in construction It is necessary to reasonably and effectively guarantee the construction quality, and carry out comprehensive control in combination with scientific management methods.

Pipe installation -selection and inspection of pipe materials

Pipes and major fittings are provided by selected qualified manufacturers. After the pipes enter the site, the material engineer of the construction party will verify the quality of the products. When the visual inspection cannot ensure the quality of the pipe, carry out internal and external pressure tests. The pipes entering the site must be products that have passed the batch inspection of professional laboratories and obtained inspection reports.

Pipe Installation - Downpipe  

After the cushion flat foundation is accepted, it can be installed when it reaches a certain strength. During construction, remove the sludge, debris and accumulated water on the surface of the foundation before piping, and check the center position and elevation of the elevation model. The pipes flow from downstream to upstream. The lower tube is manually matched with a truck crane above 8 t. When laying pipes, hang down the pipe joints stably, use a chain hoist to move the pipes to the interface of the pipe arrangement, arrange and place them manually, adjust the elevation and axis of the pipe joints, and make the pipes connect smoothly.

Completion acceptance stage

1. Closed water test

1.1 Inspection work before the closed water test Check that the appearance quality of the pipeline and the well is qualified; the pipeline is not backfilled and there is no water in the trench; except for the reserved water inlet and outlet pipes, all reserved holes are sealed and impermeable; both ends of the pipeline are blocked The bearing capacity has been calculated and is greater than the resultant force of water pressure.

1.2 Method of closed water test

The closed water test of the drainage pipeline should be carried out in sections from upstream to downstream. After the test in the upstream section is completed, water can be poured into the downstream section to save water. The test pipe section shall be separated according to the well spacing, and the well test shall be carried out by the construction engineer for every 3 well sections. When the design water head upstream of the test section does not exceed the inner wall of the pipe roof, the test water head shall be calculated by adding 2m to the inner wall of the pipe roof upstream of the test section.

1.3 Backfilling trenches and restoring pavement

The backfilling of the trench should be carried out in a balanced manner from both sides of the pipeline. There should be no accumulated water in the trench, and humus, garbage and silt should not be used for backfilling. The backfill soil should not contain broken bricks, stones, concrete fragments and hard soil blocks larger than 10mm . After backfilling, all construction grounds shall be restored quickly and carefully, and their compactness shall be measured and recorded.

Conclusion

In the current process of municipal engineering construction, the construction quality of water supply and drainage and the operation mode of the city are fully utilized to ensure that the application of urban functions can be based on the application of water supply and drainage projects, and its application methods and application models are strictly managed and controlled. And it can provide timely guarantee for the road problems that are easy to appear in the city and the safety problems during the flood season. Therefore, only by strengthening the quality control and management of each link in the construction can we ensure timely and reasonable control of various quality problems during the construction process.HDPE Pipe Suppliers
