Cold-resistant and heat-resistant cold and hot dual-purpose stainless steel composite pipe

Abstract

The invention provides a cold-resistant and heat-resistant cold and hot dual-purpose stainless steel composite pipe, and relates to the technical field of stainless steel composite pipes. The cold-resistant and heat-resistant cold and hot dual-purpose stainless steel composite pipe comprises an inner pipe, the outer surface of the inner pipe is fixedly connected with a plurality of evenly-distributed spaced circular rings, the outer side walls of the spaced circular rings are sleeved with an outer pipe, and a first semicircular block is arranged on the rear side of the outer side wall of the outer pipe; a second semicircular block is arranged on the front side of the outer side wall of the outer pipe, clamping blocks are fixedly connected to the top and the bottom of the side, close to the second semicircular block, of the first semicircular block, and the gap between the inner pipe and the outer pipe is conveniently guaranteed by arranging the multiple spaced circular rings, the outer pipe, a heat preservation layer, the first semicircular block and the second semicircular block; and meanwhile, the heat preservation layer is arranged, heat preservation is achieved to a certain degree through the gaps and the heat preservation layer, and then cold resistance and heat resistance of the inner pipe are achieved.

Description

technical field [0001] The invention relates to the technical field of stainless steel composite pipes, in particular to a cold and heat resistant dual-purpose stainless steel composite pipe. Background technique [0002] The stainless steel composite pipe has high technical content, precise equipment, advanced technology and stable product quality, and is automatically controlled by computer. The product has the characteristics of luxurious and beautiful appearance of pure stainless steel and high strength of ordinary carbon steel pipes. Its price is lower than that of pure stainless steel pipes, and it is a substitute for expensive stainless steel structural decorative pipes. [0003] The existing stainless steel composite pipe usually has only one layer, but due to the characteristics of the metal when the existing stainless steel composite pipe is used, the thermal conductivity of the composite pipe is good and the cold resistance is poor. When carrying out hot water tra...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing stainless steel composite pipes in the prior art have good thermal conductivity and poor cold resistance due to the characteristics of the metal when they are in use. When carrying out hot water transportation, it is easy to cause personnel scald, or when the external temperature is low, the water in the composite pipe is easy to freeze, which will cause the problem of blockage of the composite pipe, and a cold and heat resistant stainless steel composite pipe for cold and heat is proposed.
