Product application: Heating supply,cooling supply, anti-corrosion in the field of crude oil delivery, insulation pipeline engineering. medium temperature: ≤120℃ (Accidental peak＜140℃). medium pressure: ≤2.5MPa. laying mode: It is mainly used for direct laying, as well as for trench or overhead laying pipeline.
The mechanical properties of the outer protection pipe are improved. The thickness of the outer protection pipe is reduced. the water absorption of the insulation layer is reduced. The percentage of close area of the insulation layer is improved. The axis eccentricity of insulation pipe is reduced. The uniformity of insulation layer density is improved. The compression strength of the insulation layer is improved. The thermal conductivity of the insulation layer is reduced and the energy loss is reduced.
