Title:
STEAM TRACING PIPE END PROTECTION SLEEVE
Document Type and Number:
WIPO Patent Application WO/2019/019507
Kind Code:
A1
Abstract:
A steam tracing pipe end protection sleeve, comprising a carrying pipe sleeve (1) made of a first metal material capable of welding and a steam pipe sleeve (2) made of a second metal material capable of welding. The steam pipe sleeve (2) protrudes on the periphery of the carrying pipe sleeve (1); the steam pipe sleeve (2) communicates with the carrying pipe sleeve (1); the diameter of the steam pipe sleeve (2) is less than that of the carrying pipe sleeve (1). When the steam tracing pipe end protection sleeve is mounted at the end of a steam tracing pipe, the steam pipe sleeve has a rigid positioning effect on a steam pipe, so that the influence on a sealing effect due to the vibration or shaking of the steam pipe can be avoided, so as to prevent seawater, rainwater, etc. from infiltrating the interior of an insulating layer, thereby preventing the shortening of the service life of the steam tracing pipe caused by the corrosion of the steam tracing pipe.
