Description
Technical field
The utility model relates to composite pipe tubing field, particularly relates to the pipeline of a kind of outside thread steel-plastic composite pipe and formation thereof.
Background technique
Steel-plastic composite pipe is a kind of emerging composite pipe tubing, can be divided into steel strip reinforced steel-plastic composite pipe, seamless steel pipe strengthens steel-plastic composite pipe, hole pattern steel band steel-plastic composite pipe and steel wire mesh frame steel-plastic composite pipe according to the structure of tubing.At present popular is on the market steel strip reinforced steel-plastic composite pipe, this tubing mesosphere is that high-carbon steel band docks the steel belt layer be welded by cans, internal layer is high density polyethylene (HDPE), skin is zinc coat, this tubing not only corrosion-resistant, non-corrosive, not incrustation, clean nontoxic, and load performance is superior, the life-span is long.According to test, the working life of steel-plastic composite pipe is more than three times of common Coating Steel Pipe, makes the purposes of steel-plastic composite pipe very extensive, and your conveying of oil, rock gas, the various field of work pipes for mining, water drinking tube, waste pipe etc. all relate to.
Although steel-plastic composite pipe superior performance, also there is shortcoming in it.Existing lining moulds outside thread steel-plastic composite pipe, carries out outside thread add man-hour at tubing two ends, easily pipe in damage plastic cement.In actual applications, according to demand each section of tubing cut is coupled together, outside but the section of tubing is easily exposed to, after Long-Time Service, the infiltration of liquid very easily makes the division of inner plastic and breaks, stainless steel lining is oxidized then, corrosion, greatly reduces the working life of pipeline.Therefore be necessary that the port to tubing carries out the process of intensity enhancing, anti-corrosion.
Model utility content
In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art, the pipeline providing a kind of outside thread steel-plastic composite pipe and be made up of it, the utility model effectively prevents pipe end plastic layer to be separated with steel pipe layer, improves the working life of tubing.
In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize:
A kind of outside thread steel-plastic composite pipe, near port, machine shaping has outside thread to the outer surface of described steel-plastic composite pipe, it is characterized in that, described steel plastic compount tube opening is embedded with stainless steel lining, the described outer surface of stainless steel lining and the internal surface of steel-plastic composite pipe are close to mutually, one end of described stainless steel lining is provided with flange, and described flange is close to the port surface of steel-plastic composite pipe.
Stainless steel lining expands swelling and is bonded in steel-plastic composite pipe port, carrying out outside thread and adds man-hour, protecting pipe material inner wall plastic layer from weighing wounded at tubing.After installation is laid in tubing construction, serve the effect of coated protection to pipe end, prevent sewage to infiltrate between inwall plastic layer and steel layer, the problem that solving splits gets rusty, improves the working life of pipeline.
When stainless steel lining cover is embedded steel-plastic composite pipe port, use expansion holding tool and lining is expanded, expand holding tool and comprise by the interconnective hydraulic hand-pump of hydraulic oil pipe and expander.Lining expands concrete step:
(1) choose stainless steel lining according to the specification of steel-plastic composite pipe tubing, the external diameter of stainless steel lining is slightly less than normal than the internal diameter of steel-plastic composite pipe, and namely stainless steel lining just can embed pipe end manually and don't easily drop as the best;
(2) pipe end inwall is wiped clean, equating port burr, overall for stainless steel lining appearance is filled bonding glue, then lining is filled in pipe end, and clap and put in place, shed unnecessary glue;
(3) expander expanding holding tool is filled in the stainless steel lining at pipe end place, make pipe end face, lining flange and expander three mutually compress and put in place, and keep concentric parallel;
(4) hydraulic hand-pump is operated, oiling is suppressed to expander inside, expander expands extruding lining and swells, and notes pressure gauge numerical value, when force value reaches simultaneously, stop suppressing oiling, enter the dwell time, the dwell time reaches, and opens compression relief cock, expand holding tool retract exit, stainless steel lining just swelling be bonded on steel plastic compount tube opening;
(5) before lining bonding glue does not also solidify, outside thread processing is carried out.
Preferably, described flange complete steel-plastics covered composite pipe port surface.
Adhesive layer is provided with between described stainless steel lining and steel-plastic composite pipe.
Adhesive layer is the structure after adhesive glue water cure, and adhesive layer improves the bond effect of lining and plastic layer, effectively prevents in the gap of seeping water between inflow lining and plastic layer.
The pipeline be made up of outside thread steel-plastic composite pipe, it comprises the outside thread steel-plastic composite pipe of inner liner stainless steel lining and straight-through internal thread tube piece, and described straight-through internal thread tube piece is for connecting two outside thread steel-plastic composite pipes.
Compared with prior art, the utility model has following beneficial effect:
(1) steel-plastic composite pipe port inner wall is close to completely by stainless steel lining, then carries out outside thread and add man-hour, effectively prevents coming off and being separated of internal layer plastic layer;
(2) the complete coated tubing port surface of the flange of stainless steel lining, seeps water after preventing Long-Time Service and washes away being separated of the plastic layer that causes and steel layer to port surface;
(3) good connecting effect between the steel-plastic composite pipe of inner liner stainless steel lining, long service life.
