What's the difference between black and yellow polyurethane insulating steel pipes

There are black and yellow polyurethane insulating steel tube shell. What's the difference between them? Let's introduce them above.

The construction of yellow jacket insulation pipe includes task steel pipe layer, polyurethane insulation layer and high density polyethylene maintenance layer. One of the inner layers is covered by black or yellow polyethylene plastic materials prefabricated to a certain wall thickness. Black jacket insulation pipe is called black jacket insulation pipe, yellow jacket insulation pipe is called yellow jacket insulation pipe. Its function is to maintain the polyurethane insulation layer from the destruction of mechanical hard objects, and the second is anti-corrosion and waterproof. High density polyethylene polyurethane foamed insulation steel pipe execution: SY/T114-2000 and SY/T115-2001 specification.

Everyone knows that in polyurethane thermal insulation steel pipe, the secondary types of steel pipe are spiral steel pipe and seamless steel pipe. When should these two kinds of steel pipe be used in detail?

Spiral steel pipe is a kind of welded steel pipe, which is not strong enough to bear pressure. It is mostly used as a water conveyance pipeline.

Seamless steel pipes are used for large pressure bearing capacity; seamless steel pipes are those without welds, which can be used as steam pipes and oil and natural gas pipelines.
