Abstract
The invention discloses a kind of lining plastic stainless steel tube manufacture method, the lining plastic stainless steel tube manufacture method is comprised the following steps：A, cleaning treatment is carried out to stainless steel pipe inner surface；B, coat hotmelt in plastics tube outer surface；C, plastic tube is embedded in steel pipe and seals two ends；D, to being passed through pressure saturated vapor in plastic tube and stainless steel tube outer surface heated.A kind of lining plastic stainless steel tube manufacture method of the present invention, by being passed through pressure saturated vapor in plastic tube and stainless steel tube outer surface being heated, stainless steel tube and plastic tube can be bonded quickly through hotmelt, and cause that plastic tube softens expansion in the presence of pressure saturated vapor and produces deformation, make it bigger more stable with the adhesion of stainless steel tube, so as to substantially increase lining plastic stainless steel tube performance and life-span.
Description
Technical field
The present invention relates to a kind of stainless steel tube manufacture method, more particularly to a kind of lining plastic stainless steel tube manufacture method.
Background technology
The classical production process of lining plastic stainless steel tube is to be combined together stainless steel tube and plastic tube extruding using drawing process, but it is weaker that it combines dynamics, after pipe bending or use time more long, gap is easily produced between stainless steel tube and plastic tube, so as to influence its performance.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of combination dynamics is good, long service life lining plastic stainless steel tube manufacture method.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of lining plastic stainless steel tube manufacture method, comprises the following steps：A, cleaning treatment is carried out to stainless steel pipe inner surface；B, coat hotmelt in plastics tube outer surface；C, plastic tube is embedded in steel pipe and seals two ends；D, to being passed through pressure saturated vapor in plastic tube and stainless steel tube outer surface heated.
Preferably, being cleaned to steel pipe internal-surface using alkaline defatting agent in the step A.
Preferably, hotmelt applied thickness is 0.3-0.5 millimeters in the step B.
Preferably, the saturated vapour pressure being passed through in the step D is 10-12MPa.
Preferably, being heated to stainless steel tube outer surface using plasma heater in the step D.
Compared with prior art, a kind of lining plastic stainless steel tube manufacture method of the present invention, by being passed through pressure saturated vapor in plastic tube and stainless steel tube outer surface being heated, stainless steel tube and plastic tube can be bonded quickly through hotmelt, and cause that plastic tube softens expansion in the presence of pressure saturated vapor and produces deformation, make it bigger more stable with the adhesion of stainless steel tube, so as to substantially increase lining plastic stainless steel tube performance and life-span.
