Common problems and solutions in fiberglass production  

Why do fiberglass pipes have stains?

The smoothness, cleanness and cleanliness of the surface of the fiberglass tube is the basis for its appearance. During production, stains, especially black oils, are sometimes found on fiberglass pipes. What causes a stain on a glass tube?

1.Emerging as a result of a previous process

2.Penetration of water, oil or other pollutants through spot steel pipes

3.Cross - colors

4. Dragging a floor contaminated with dust or other waste

5.The paint is unclean, with impurities or mixed with other colors

6.How to reduce stains on fiberglass pipes? Firstly, it is important to regularly clean and maintain the equipment. The process process is relatively complete, 5S cleaning work needs to be done. Secondly, strengthen quality control in the quality sector to avoid leakage of unwanted goods

二、What is the reason for the uneven color of fiberglass?

The process of producing fiberglass pipes is relatively simple and has several basic steps, including weaving, painting and gluing, packaging and storage. Why does this process result in uneven color in the fiberglass? Let's analyze it using a regular white fiberglass tube.

The reasons for the uneven color of fiberglass are as follows:

1.The dewaxing temperature is set incorrectly.

2.Dewaxing temperature is unstable

3.External cold air enters the dewaxing oven

4.Unusual weaving of casting pipes

Causes of insufficient pressure (stability) of fiberglass pipes

Fiberglass pipes can be divided into 1.2KV fiberglass pipes, 1.5KV fiberglass pipes, 2.5KV fiberglass pipes, 4KV fiberglass pipes and 7KV fiberglass casing pipes depending on their pressure class. Among them, 1.2 kV and 1.5 kV fiberglass pipes due to similar technology and pressure level have been standardized into 1.5 kV fiberglass casing pipes.

According to technical standards, the actual strength level of glass casing during production must be much higher than the rated stress value. For example, 1.5 kV fiberglass tubing can withstand pressures of about 2.5 kV. In industry standards, fiberglass tubes can sometimes have some extreme individual values, such as the actual voltage of a 1.5 kV fiberglass tube measured at a specific node is 1 kV. This is acceptable within industry standards and is not necessarily an unqualified product.

What are the reasons for insufficient pressure level (stable) when detecting poor quality fiberglass pipes?

1.Low paint concentration

2.Formation of bubbles

3.Crude rubber quality problems

4. Poor weaving of square tubes, excessive thinning and loosening

5. Errors in the work of employees
