How much is a set of cast iron drain pipes - PVC drain pipe**.
Cast iron drain pipe and PVC drain pipe are two common drainage pipe materials, which are widely used in construction projects. In the market, cast iron drain pipes and PVC drain pipes** vary depending on the model, specification, quality, and other factors. This article will introduce the cast iron drain pipe and PVC drain pipe respectively, and ** their characteristics and application range.
1. Cast iron drain pipe**.
Cast iron drain pipe is a traditional drainage pipe material, which has the advantages of high strength, corrosion resistance, and long life. The first grade of cast iron drain pipe varies according to different specifications and manufacturers, generally ranging from tens of yuan to several hundred yuan.
The common specifications of cast iron drain pipes are DN50, DN100, DN150, etc., which are suitable for the drainage system of various construction projects, such as roofs, balconies, basements, etc.
The cast iron drain pipe is relatively high, but its excellent properties make it the preferred material for some high-end construction projects. At the same time, the installation and maintenance cost of cast iron drain pipe is also relatively low, which can save some construction costs.
2. PVC drain pipe**.
PVC drain pipe is a new type of drainage pipe material, which has the advantages of lightweight, corrosion resistance, and low cost. The ** of PVC drain pipe is generally ranging from a few yuan to dozens of yuan, which is more close to the people than the cast iron drain pipe. The common specifications of PVC drainage pipes are DN40, DN50, DN75, etc., which are suitable for the drainage system of various ordinary construction projects.
Although the PVC drain pipe is lower, its performance is also relatively poor. For example, the compressive strength and durability of PVC drain pipes are not as good as those of cast iron drain pipes, and they are easily damaged by external factors. Therefore, when choosing a PVC drain pipe, you need to pay attention to its quality and use occasion.
In short, cast iron drain pipe and PVC drain pipe have their own characteristics and application range. The selection needs to be based on factors such as engineering requirements, budget and performance requirements. If a high-quality and long-life drainage system is required, cast iron drain pipes can be selected; If you need a low-cost and lightweight drainage system, you can choose a PVC drain pipe.
