Compared with ordinary FRP pipes, the price of chemical FRP pipes is relatively expensive. Because it need to be made of special materials. So what are the factors that affect the price of chemical glass steel pipe? What should we pay attention to when purchasing?
Factors affecting the price of chemical glass steel pipe:
1.Material factors
We all know that most of the pipelines in the chemical industry need to be kept in a corrosive environment for a long time. This requires high corrosion resistance of the material, so an epoxy anticorrosion layer should made on the inner layer of the pipe wall. The high price of this material will affect the unit price of the entire tube;
2. labor cost
If we use epoxy resins to make all the pipes , the cost will stay on a relative high level. So we will switch to ordinary materials in the outer layer after comprehensive consideration. These common materials also have anti-corrosion properties. But they will also be corroded if they are left in a corrosive environment for a long time. However, the cost of this material is low, and the strength can meet the requirements of use, so the use of ordinary materials for the outer layer can help reduce costs. However, material switching will cause material waste and labor costs. Although it is still lower than the price of using full epoxy resin, this is also one of the factors that affect the price of chemical glass steel pipe.
Precautions for purchasing FRP pipes for chemical industry:
1.It is necessary to pay attention to whether the inner layer has an epoxy anti-corrosion layer, and it is necessary to know the thickness of the epoxy anti-corrosion layer. We generally require the manufacturer’s epoxy anti-corrosion layer to be no less than 2mm.
2. It is necessary to pay attention to whether there are anti-corrosion requirements during installation in the installation instructions. Generally, the factory manual will make an installation manual for the installation of glass steel pipe to guide the installation work of the construction party. This installation manual is particularly important for the guidance of anti-corrosion schemes.
3. The last point is the manufacturer’s warranty period for the product. The manufacturer’s quotation generally includes the cost of product quality assurance, and the price of chemical glass steel pipe includes after-sales costs, so the length of the warranty period depends on the manufacturer’s confidence in the product.
