The characteristics of our solar connecting pipe
Healthy and Safe:
As a connection between solar collector panel and thermal insulation tank, pipeline are usually placed in an outdoor environment and exposed to the weather. UK Willie solar energy connectors made of stainless steel 304 can work perfectly at the ambient temperature ranged from-70 degrees to 120 degrees without precipitation of harmful substances. The PVC coating of outer pipe can prevent Willie pipes from sun exposure and rain erosion, which improves their corrosion and ageing resistance.
Hygienic and Efficient
As the heat exchange pipeline in the thermal insulation tank, the pipeline made of stainless steel 304 of UK Willie can ensure the product characteristics of the hygienic level and the hygienic standards of household water supply.
The stainless steel is not rusty in warm water for a long time with the heat conduction coefficient of up to 0.039cal/COM. S. ° C, and fully meets the needs of heat exchange pipes.
Unique Structure and Technology
More importantly, due to the unique processing technology of Willie pipeline products, in the whole piping system, the inner pipe wall has a spiral structure. Because of fluid mechanics principles, the water flow in pipelines is actually a mixture of two streams. The middle straightway water flow and spiral turbulent flow make pipelines, which run hot water for a long time, unable to produce scaling and other polluting substances. This ensures the cleanness inside pipelines and further improves the hygienic quality of water sources, while saving the cost of cleaning the inner pipeline wall.
The Most Efficient, Safe and High-Quality Connection:
Threaded connection: Threaded connection is the most mature way of pipeline connection, which is reliable with simple structure of pipe fittings, but the connection has high requirements on pipes and the wall thickness of pipe fittings.
After constructor are familiar with our loose joint approach, the probability of construction mistakes and leakage will be greatly reduced by reducing the construction time as well as the number of connectors which is 50% less than that of traditional pipelines so as to enhance the project quality of the whole system.
