Which material of rectangular pipe jacking mold has longer service life?

The rectangular pipe jacking mold is a tool used to produce cement products and is often used to manufacture drainage pipes with rectangular cross-sections. Material is an important consideration when selecting a rectangular pipe jacking mold. Molds made of different materials have different wear resistance, pressure resistance and corrosion resistance. These characteristics directly affect the service life of the mold. So, which material of rectangular pipe jacking mold has a longer service life?

Common rectangular pipe jacking mold materials include steel, cast iron, plastic, rubber, etc. The following will conduct a detailed analysis of the rectangular pipe jacking molds made of these materials, and compare their advantages and disadvantages, as well as the differences in service life.

First of all, steel is a common material for rectangular pipe jacking molds. Steel has excellent compression resistance and wear resistance, can withstand high pressure, and is not easily deformed. In addition, steel has good stability and can work normally in different temperature and humidity environments. Steel rectangular pipe jacking molds usually adopt precision processing technology, with smooth surface and precise dimensions, and can produce high-quality cement products. However, the disadvantage of steel is that it is prone to rust and requires enhanced protection in humid environments to extend its service life. In addition, the cost of steel is relatively high, which may cause certain investment pressure for mass-produced rectangular pipe jacking molds.

Second, cast iron is another common material for rectangular pipe jacking molds. Cast iron has good wear resistance and impact resistance, and can withstand high pressure. Compared with steel, the cost of cast iron is relatively low and the manufacturing process is relatively simple. However, cast iron molds are denser and heavier, making them inconvenient to transport and install. In addition, cast iron has poor corrosion resistance and is easily corroded by chemicals such as acids and alkalis, so protective measures need to be taken to extend its service life.

Third, plastic is a relatively common material for rectangular pipe jacking molds. Plastic molds are lightweight, easy to transport and install, and easy to use. At the same time, the manufacturing process of plastic molds is relatively simple and the cost is low. In addition, plastic has good corrosion resistance and is not easily corroded by chemicals such as acids and alkalis. However, plastic materials have relatively poor pressure resistance and wear resistance and are easily damaged by external forces. Therefore, the service life of plastic molds is relatively short and is generally suitable for low-frequency, small-scale production needs.

Rubber is a relatively special material for rectangular pipe jacking molds. Rubber molds have good wear resistance and impact resistance, and can withstand high pressure. Compared with other materials, rubber molds have better elasticity, are not easily deformed and are easy to install. In addition, the rubber material has good waterproof performance, which can effectively prevent cement slurry from leaking and improve the quality of the product. However, rubber materials have poor corrosion resistance and are easily corroded by chemicals such as acids and alkalis. Protective measures need to be strengthened to extend their service life.

In summary, rectangular pipe jacking molds made of different materials have their own advantages and disadvantages. Steel has excellent pressure resistance and wear resistance and has a long service life, but it needs to be rust-proofed. Cast iron has better wear resistance and impact resistance and is lower in cost, but its service life is affected by corrosion. Plastic molds are lightweight and low-cost, but have poor wear resistance and a relatively short service life. Rubber molds have good pressure resistance and wear resistance, and are easy to install, but have poor corrosion resistance. Therefore, according to specific production needs, choosing the appropriate material for the rectangular pipe jacking mold can better extend the service life and improve production efficiency.
