Some common problems with fiberglass pipes, an article will take you to understand

Recently, many clients have inquired about how to choose fiberglass pipes. Next, I will introduce the selection of fiberglass pipes to everyone:

Fiberglass reinforced plastic props have the characteristics of strong corrosion resistance, internal and external lubrication, low energy consumption for transportation, and long service life. They are widely used in industries such as petroleum, electricity, chemical industry, papermaking, urban water supply and drainage, factory sewage treatment, seawater desalination, and gas transportation. Service life (over 50 years), convenient transportation and installation, low protection cost, and low cost.

The following is an analysis of common problems with fiberglass steel pipes

1、 Post curing issues

The main reason for blistering after curing is that the evaporation of glue is too high, the rolling temperature is low, the rolling speed is fast, and the glue evaporation is too late to evaporate, resulting in residues in the pipe. When the pipe is heated and solidified, the residual evaporation is heated and expanded, increasing the evaporation of residual water in the pipe. It will cause bubbles in the pipes.

Solution: control evaporation, properly increase rolling temperature and reduce rolling speed. The reason for tube wrinkling after solidification is high rubber content. Solution: properly reduce rubber content of rubber cloth and reduce rolling temperature.

2、 Reasons for layering of fiberglass steel pipes:

1. The adhesive tape is too old; The amount of adhesive tape is too small or uneven; 3. The temperature of the hot roller is too low, the resin does not melt well, and the adhesive tape cannot stick well to the core; 4. Low tension of adhesive tape; 5. Excessive use of oil release agent can contaminate the core fabric. Solution: 1. The adhesive content and soluble resin content of the adhesive tape should meet the quality requirements; The temperature of the hot roller should be increased to make the adhesive tape soft and sticky through the hot roller, making the pipe core firmly bonded; 3. Adjust the tension of the adhesive tape; 4. There is no need to use degreasing agents or reduce their dosage.

3、 Inner wall blistering

The main reason is that the guiding head cloth is not close to the core.

Solution: During operation, it should be noted that the guiding head cloth should be firmly attached to the pipe core.
