Double Wall Corrugated Pipe Compares Steel Belt Reinforced Corrugated Pipe

Among the municipal drainage sewage pipes, there are relatively many Double Wall Corrugated Pipe and Steel Belt Reinforced Corrugated Pipe. So what is the difference between these two pipes?

1. Ring stiffness

The ring stiffness of the Double Wall Corrugated Pipe is SN4 and SN8; while the ring stiffness of the Steel Belt Reinforced Corrugated Pipe is SN8, SN10, SN12.5, SN16; the latter embedded in the latter Its competitive advantage is even more obvious. Although the ring stiffness of the Double Wall Corrugated Pipe is slightly weaker, the good ringgit performance also makes it a place in the market.

2. Production caliber

Double Wall Corrugated Pipe is generally DN200-DN800mm, and the diameter of Steel Belt Reinforced Corrugated Pipe can produce DN300-DN3000mm.

3. Raw materials and production technology

There are many PE raw materials for squeezing and forming of Double Wall Corrugated Pipe. The molding process is mainly formed by pipes. The pipes are cut off and expanded. The use of raw materials is a native material recycled in the market, so the price is relatively cheap. The Steel Belt Reinforced Corrugated Pipe is based on high -density polyethylene as the basis, and the steel belt that are coated with the surface shaped as the waveform as the waveform as the main support structure. Uniform, and the cost is reduced as the caliber increases, and the cost -effectiveness in similar pipes is high.

4. Price difference

The increase in production technology has made the production cost of Steel Belt Reinforced Corrugated Pipe higher than that of Double Wall Corrugated Pipe, but with the continuous research and development and improvement of the process, it is only slightly higher. Two products with slightly different prices have a common advantage in price, compared to other similar pipes, such as metal ripples.

5. Different application fields

It is also because of the strength, that is, the different rings, the application field of the two has a certain difference. For example, the highway drainage project that can be applied by Steel Belt Reinforced Corrugated Pipe, and many of the Double Wall Corrugated Pipe are not suitable for construction.

6. Different burial depth

The Double Wall Corrugated Pipe is distinguished from S1 and S2 according to different strengths, and S2 is stronger than S1. The depth of the S2 level is only two and a half meters, which is far less than the Steel Belt Reinforced Corrugated Pipe. It can be buried to 6-7 meters. It is several times that of Double Wall Corrugated Pipe.

7. Different connection methods

The connection method of the Double Wall Corrugated Pipe is single, limited to the inheritance type, the effect of closed water is poor, and it is easy to leak water. Steel Belt Reinforced Corrugated Pipe is commonly used in electrical tropical, hot shrinkage, jug connection, hot -melt welding, or combined connection.
