Sampling heat-tracing composite pipeline capable of automatically resetting after bending and manufacturing method thereof

Abstract

The invention discloses a sampling heat-tracing composite pipeline capable of automatically resetting after bending and a manufacturing method thereof, and particularly relates to the field of sampling tools. The sampling heat-tracing composite pipeline comprises an outer sheath, double-sided aluminum foil, glass fibers, a nanometer fireproof layer and a PTFE pipe, wherein the PTFE pipe is sequentially sleeved with the sheath, the double-sided aluminum foil, the glass fibers and the nanometer fireproof layer, anti-bending mechanisms are arranged on the surface of the outer sheath, and the anti-bending mechanisms are fixedly connected. The sampling heat-tracing composite pipeline has the beneficial effects that the anti-bending mechanisms are arranged, spacer bushes in the anti-bending mechanisms are fixedly connected through memory metal strips, then in the spacer bush bending process, the memory metal strips can automatically return to the original positions after being not stressed, and therefore the bent positions are automatically reset; and anti-bending grooves are formed in and spiral supporting pieces are arranged on the surfaces of the spacer bushes, so that the bending resistance of the spacer bushes can be greatly enhanced, and the sampling heat-tracing composite pipeline is prevented from being easily bent.

Description

technical field [0001] The invention relates to the field of sampling tools, in particular to a curved automatic reset sampling heating composite pipeline and a manufacturing method thereof. Background technique [0002] Sampling and heating composite pipeline is mainly used for monitoring and controlling system to collect sample gas (liquid), and transport gas from sampling place (such as chimney, engine, heat tracing sampling probe joint) to analysis and measuring instrument (mass spectrometer, gas chromatograph) etc.), widely used in petroleum, chemical, electric power, metallurgy, coking, environmental protection and other industries. [0003] In the prior art, most of the traditional sampling and heat-tracing composite pipelines do not have a memory function, that is, they cannot return to their original positions after being bent again, and the existing sampling and heat-tracing composite pipelines are easy to bend, which may easily cause damage to internal components....
