What are the features and advantages of HDPE corrugated pipe in Singapore municipal engineering? What knowledge do I need to know when purchasing HDPE corrugated pipes for Singapore? What is the customs commodity code for HDPE bellows?

HDPE double-wall corrugated pipe is a new type of lightweight pipe with polyethylene (HDPE) as raw material, processed by extrusion and special molding process, with smooth inner wall and closed corrugated outer wall. The double-wall corrugated pipe has beautiful appearance and special structure. It has the advantages of light weight, high strength, acid resistance, corrosion resistance, compression resistance, convenient construction, material saving, reliable connection, and not easy to leak. It is a green and environmentally friendly high-tech product. Therefore, in Singapore, HDPE double-wall corrugated pipes are widely used.

Product features of HDPE double wall corrugated pipe

In the Singapore market, HDPE double-wall corrugated pipes are widely used because of their good performance and environmental protection. In Singapore municipal engineering, the corrugated pipes used are basically this kind. So what are its specific characteristics?

  • HDPE double-wall corrugated pipe has unique structure, high strength, compression resistance and impact resistance.

  • The inner wall is smooth, the frictional resistance is small, and the overflow is large.

  • The HDPE double-wall corrugated pipe is easy to connect, the joint is well sealed, and there is no leakage.

  • Light weight, fast construction and cost reduction.

  • The buried service life is more than 50 years.

  • Polyethylene is a hydrocarbon polymer, the molecule is non-polar, and it is resistant to acid and alkali corrosion.

  • The raw materials are green and environmentally friendly materials, non-toxic, non-corrosive, non-scaling, and can be recycled and reused.

  • HDPE double-wall corrugated pipe has a wide operating temperature range, the pipeline will not break in the environment of -10 °C, and the maximum temperature of the conveying medium is 40 °C.



HDPE double wall corrugated pipe is widely used

Because the inner wall is smooth, the resistance of the fluid is small, and the flow rate is naturally large when the resistance is small. Moreover, because of the characteristics of the material, its weight is also very light, and it is also very convenient for handling, installation and construction, and it is resistant to corrosion and aging, and has strong adaptability. .

HDPE double-wall corrugated pipes are applied to the drainage and ventilation pipes of mines and buildings, and the drainage and ventilation are very smooth;

HDPE double-wall corrugated pipes are used in Singapore municipal engineering, underground drainage and sewage pipes in residential quarters. Because of the low resistance of the pipe wall, sewage and rainwater can pass through quickly, increasing the drainage volume and preventing the city from being submerged by water;

HDPE double-wall corrugated pipes are applied to farmland irrigation and water supply and drainage. There is a lot of sediment in farmland, water conservancy projects, and drainage. If the pipe wall is easy to accumulate sediment, then the pipe is easily blocked and affects the drainage effect;

HDPE double-wall corrugated pipes are applied to the drainage pipes of sewage treatment plants and garbage treatment plants;

HDPE double-wall corrugated pipes are applied to chemical ventilation pipes and chemical and mine transportation pipes for fluids;

HDPE double-wall corrugated pipes are applied to the overall processing of pipeline inspection wells and expressway pre-buried pipelines;

HDPE double-wall corrugated pipes are applied to high-voltage cables, post and telecommunication cable protection sleeves, etc.

In the entire drainage system in Singapore, HDPE double-wall corrugated pipes are often seen. If you are in Singapore and are considering purchasing HDPE double wall corrugated pipe, then our corrugated pipe products will meet your needs.

What you need to know when purchasing HDPE double wall corrugated pipe

HDPE double-wall corrugated pipe and HDPE hollow winding pipe are different, and their prices are also different for different processes. If you need to purchase HDPE double-wall corrugated pipe in Singapore, you should also know the relevant knowledge.

1. The production process is different.

HDPE double-wall corrugated pipe is made of two concentric pipes with smooth inner wall and corrugated outer wall in the extrusion molding process, and the production process of embryo, one-time extrusion welding, extruded polyethylene (HDPE) hollow winding pipe is based on high Density polyethylene (HDPE) is used as raw material, which is wound and welded into a rectangular shape.

2, the price is different.

The price of hollow wound pipes with the same specifications and ring stiffness is higher than that of HDPE double-wall corrugated pipes. The production process of HDPE double-wall corrugated pipe and HDPE hollow winding pipe is different, and the utilization rate of raw materials is also different. When producing pipes with the same pipe diameter and the same ring stiffness, the utilization rate of raw materials is high during the extrusion process, that is, the hollow wound pipe requires more materials, and the production cost is relatively high, so the price is also high.

3, the caliber is different.

The production process of HDPE double-wall corrugated pipe is an extrusion molding process, and the die size of the equipment is the same as the diameter of the pipe. Therefore, if a large-diameter HDPE double-wall corrugated pipe is to be produced, the mechanical equipment of a large mold is used. The research and development costs are high, and currently only the largest diameter double-wall corrugated pipe can be produced in China, up to DN1200mm. HDPE hollow winding pipes are produced in a diameter range of 300-2200mm and a length of 6-10 meters.

4. The ring stiffness is different.

HDPE double-wall corrugated pipe ring stiffness is SN4, SN8, SN10, SN12.5 four grades, HDPE hollow wall winding pipe ring stiffness can reach SN8, SN10, SN12.5, SN16 four grades.

5, the connection method is different.

The HDPE hollow winding pipe is connected by a hot melt tape, and the interface is heated and welded. The connection method is more complicated, and the connection cost is slightly higher than that of the double-wall corrugated pipe. The HDPE double-wall corrugated pipe mainly adopts socket connection and is sealed by rubber sealing ring. This connection method is easy to install and the installation cost is relatively low.

How many meters is a HDPE double-wall corrugated pipe?

The length of a corrugated pipe is long or short, 4 meters, 6 meters, but the basic effective length is 6 meters, especially a double-wall corrugated pipe of hdpe, its length is set to 6 meters. But there are many specifications, mainly referring to its outer diameter of 200 mm, 250 mm, 300 mm, 400 mm. Slightly larger ones can reach 500mm, 600mm and 800mm, but are basically produced in six-meter lengths. If this length does not meet the requirements, you can choose to customize the HDPE double-wall corrugated pipe.

We understand the Singapore market, and our products are also market-tested premium products. The length of one HDPE corrugated pipe is the basic information. Our HDPE corrugated pipe factory will provide customized solutions to meet your municipal engineering needs.

Double-wall corrugated pipe for Singapore drainage system

  • If hdpe double-wall corrugated pipes are selected in Singapore municipal engineering, they have strong compressive ability because of their higher molecular weight and better mechanical properties. For example, PE resin has relatively strong tensile strength, but poor pressure resistance and complicated connections, so it is not suitable for use as a hydraulic pipe material.

  • Another advantage of hdpe corrugated pipe in Singapore drainage system is that it has a very smooth inner wall, which results in a higher flow rate and is not easily clogged by water. Moreover, after the product is connected in place, the interface seal is very good, has a certain degree of corrosion resistance, and is not easy to produce dirt, thus avoiding secondary pollution.

  • Double-wall corrugated pipe is known as a kind of green environmental protection pipe, which has a long service life and can be used for more than 50 years when buried in the ground. This has been widely recognized in Singapore, which is famous for its environmental protection.

The customs commodity Hs code for HDPE corrugated pipe bellows is 39173100
