Requipments of PS Distribution Loop

Plastic or fiberglass pipes and fittings are often used in water treatment projects and reverse osmosis projects. In the case of bonding, the quality and bonding strength of the adhesive must be guaranteed. The constructor is required to construct in strict accordance with the bonding process to ensure that the bonding has been cured and reaches the predetermined strength before installation. The pipe fittings such as tee and elbow connected to the pipeline should be shaped and molded by the manufacturer in cooperation with the equipment supplied.

Plastic, glass fiber reinforced plastic pipes and fittings should be used indoors and cannot be used for a long time under the hot sun. To avoid aging deterioration. The spacing between the plastic and glass fiber reinforced plastic pipe supports and hangers should meet the design requirements to avoid vertical bending deformation after being filled with medium. When using metal clamps, there should be rubber cushions. FRP pipes connected with flanges should be prevented from deforming due to uneven stress. In the process of laying pipes of different materials, steel pipes should be laid first, followed by glass steel pipes, and finally plastic pipes. Do not drill holes in fiberglass pipes.

Rubber-lined pipes should be checked for electric spark leakage before installation, and should not be in contact with solvents that can dissolve rubber during use. All flanges should be carefully inspected and subjected to strict water pressure (1.25 times the working pressure) test. Installed rubber-lined pipes must not be welded or drilled.

Pipelines used for conveying acid and alkali should not be laid overhead, and flanges and valves where people walk must have protective covers or shielding plates. Concentrated acid and alkali delivery pipes should be as long as possible to reduce joints.
