Direct buried insulation pipe life

The lifespan of the directly buried thermal insulation tube and the high temperature prefabricated direct buried thermal insulation tube can reach more than 50 years, which is 3 to 4 times higher than the traditional trench installation and overhead laying. Straight-buried insulation pipe life The direct-buried insulation pipe is tightly bonded to the steel pipe skin due to the rigid polyurethane foam insulation layer, which insulates the infiltration of air and water and can play an outstanding anti-corrosion effect. Together, its foaming holes are closed and have low water absorption. High-density polyethylene housings and FRP housings offer outstanding corrosion protection, insulation and mechanical properties. Therefore, the working steel pipe outer skin is hardly corroded by the outside air and water. Only the internal water quality of the pipeline is well treated. According to foreign materials, the service life of the high-temperature prefabricated direct-buried insulation pipe can reach more than 50 years, which is 3~4 times higher than the traditional trench installation and overhead laying.

The direct buried heating pipeline does not need to build a huge trench. It only needs to bury the thermal insulation pipe underground, thus greatly reducing the project land occupation, reducing the excavation volume of the earth by about 50%, and reducing the civil construction and concrete volume by 90%. Together, the insulation pipe processing and the on-site trenching are carried out in parallel, and only the on-site joints can shorten the construction period by more than 50%.

Peristaltic Dosing Pumps

Peristaltic Dosing Pumps Characteristic :

1 Clean and pollution-free: fluid only passes through and touches the Peristaltic Pump hose.

2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
