Structure:
Working steel tube - skid layer drag reduction, reflector, organic - inorganic layer layer - polyethylene outer protection pipe (or glass fiber reinforced plastic protection layer)
Scope of application:
Medium pressure temperature < 350 ℃ < 16 mpa
Main advantages:
Structural design is reasonable, with high temperature, heat preservation effect is good, all the weight is lighter steel set of steel, can be used for aerial pipeline network, also can be used in the directly buried, engineering cost relatively cheap steel bushing.
