Description

Double-wall pipe for power ship

Technical Field

The utility model relates to a double-wall pipe for a power ship.

Background

The double-wall pipe has light weight and is an ideal choice for transportation and welding construction of power ships. In stressed construction and construction, the advantages of double-wall pipelines are more remarkable under severe conditions. The friction coefficient of the double-wall corrugated pipe is small, and the flow is large. The flow rate of the double-wall corrugated pipe is larger than that of other pipes with the same pipe diameter under the condition of the same pipe diameter.

The double-wall pipe used by the current power ship is simple in structure, and the poor conditions such as deformation and rupture often occur under long-time work, so that the operation safety of the ship body is affected.
