FRP Spray Pipe

Hebei Weitong FRP Co., Ltd.is a first-class fiberglass manufacturing and marketing enterprise in China, which is specialized in, , FRP Mold, , , , FRP Corrosion Protection, , , FRP Bridge Support, , , .

FRP Spray Pipe( ) has many advantages such as strong corrosion resistance, smooth inner surface, low energy consumption, long service life, convenient transportation and installation, no maintenance and low overall cost in petroleum, electric power, chemical industry, papermaking, etc. Urban water supply and drainage, factory sewage treatment, seawater desalination, gas transportation and other industries have achieved wide application. The FRP sprinkler pipe is made of resin and glass fiber and is made by special techniques.

The is usually manufactured by segmentation and sub-assembly during the manufacturing process for easy transportation. When installed on site, the winding and bonding process is used to connect the parts. At present, the connection between the slurry nozzle and the FRP spray pipe is basically changed from the previous flange connection to the winding bonding process.

The winding and bonding process has the advantages of high joint strength, low leakage, simple process, convenient construction and low cost. The specific dimensions of the glass fiber surface felt can be determined based on the actual pressure and diameter. Due to the high thermal expansion rate of FRP, it is required to measure, cut, assemble and bond at the same ambient temperature during construction. Pre-prepared glass fiber reinforced materials, resin mortar, sheet resin, surface resin and contact agent are required.

The outer surface structure of the winding part should be consistent with the outer surface of the pipe to ensure that the performance of the winding part is consistent with the overall performance of the pipe. In addition, in order to prevent the slurry from corroding the butt end face of the pipe, the butt joint needs to be filled with resin mortar, and the resin used for arranging the cement is required to be consistent with the pipe resin. The outermost layer can be waxed if necessary to prevent air from entering and slitting (cracking).

Before installation, dig a groove at the pipe joint position corresponding to the foundation so that the bottom of the whole pipe body is placed on the undisturbed soil or sand cushion layer and evenly stressed. FRP spray pipes can be transported with lower cost in transportation, fuel consumption and other expenses saving.

When installing, the medium and small diameter FRP spray pipes generally do not need heavy machinery, and some can even be manually transported to improve the installation speed.

After long-term use, the sludge in the pipe and the solidification of the rust will cause the original pipe diameter to become smaller, and the smooth discharge of the maximum discharge flow cannot be satisfied. The sediment at the bottom of the pipe always raises the downstream of the drainage pipe, causing the slope of the pipeline to decrease. The flow rate is gentle, the blockage of the FRP sprinkler pipe is multiplied, and the blow down function is interrupted at any time. Therefore, regular maintenance is required.
