FRP sand sandy pipes can be used for water transmission, sewage, ventilation, and medium transmission. Because of the wide application and large amount of use, many manufacturers prevail. However, customers are easy to approach the misunderstanding of prices when buying. Only explain the specifications with the business personnel, that is, the size of the pipe diameter, the other ring rigidity, burial depth, thickness, corrosion resistance, etc., all are not mentioned.
In fact, when buying a glass reinforcement sand sandwich pipe, you need to pay attention to the following aspects:
1. The size of the pipe diameter: There are many types of pipe diameter of the glass fiber reinforced fiber reinforcement pipeline. The diameter of the glass reinforcement pipe pipes produced by our company has the specifications of the DN100-DN4000. What about the trail, you have to figure it out. Although the inner and outer diameter is only a problem with a thick wall, the price is different.
2. Thickness (ring rigidity): The thickness directly affects the price and the rings of the ring. Generally, the thickness of the glass reinforcement sand sandwich pipeline is 4-10mm, and the specific thickness is determined according to the requirements of the use.
3. Corrosion resistance: The sand reinforcement sand sandwich pipeline has the characteristics of corrosion resistance. Of course, it is only ordinary acid and alkali. If it is required to be resistant to strong acid and alkali, the ethylene resin is required. The ordinary 196 resin cannot meet the requirements.
4. Buried depth (pressure/load): Generally, the deep burial depth is about 1 meter. The deeper the buried, the greater the need to be buried.
