Description
Technical field
The utility model relates to composite pipe tubing field, particularly relates to the pipeline of a kind of groove 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, and make the purposes of steel-plastic composite pipe very extensive, your field such as conveying, work pipes for mining, water drinking tube, waste pipe of petroleum gas all relates to.
Although steel-plastic composite pipe superior performance, also there is shortcoming in it.Existing lining moulds groove steel-plastic composite pipe, when tubing two side pressure groove processing, and 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, provides the pipeline of a kind of groove steel-plastic composite pipe and formation thereof, and 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 groove steel-plastic composite pipe, near port, machine shaping has groove to the outer surface of described steel-plastic composite pipe, 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 expand swelling be bonded in steel-plastic composite pipe port, tubing pressure groove processing time, protect pipe material inner wall plastic layer from weighing wounded.After tubing construction is laid and installed, serve the effect of coated protection to pipe end, prevent sewage to infiltrate between inwall plastic layer and steel layer, solve the problem of rustiness that splits, improve pipeline working life.
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 expand extruding lining swell, note manometric numerical value, when force value reaches simultaneously, stop suppressing oiling, enter the dwell time, the dwell time reaches, and opens compression relief cock, expander retract exit, stainless steel lining just swelling be bonded on steel plastic compount tube opening;
(5) before lining bonding glue does not also solidify, pressure groove 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.
A kind of pipeline be made up of groove steel-plastic composite pipe, it comprises the groove steel-plastic composite pipe of inner liner stainless steel lining, groove pipe fitting and groove pipe fitting O-ring seal, described groove pipe fitting O-ring seal is placed in groove pipe fitting, described groove pipe fitting comprises two semi-rings relatively connected, and two steel-plastic composite pipes are fastenedly connected by screw bolt and nut by described two semi-rings.
Described groove pipe fitting seal ring forms T-shaped cavity, and the lower end of described T-shaped cavity is corresponding with the gap that two are connected between steel-plastic composite pipe.
The lower end of described T-shaped cavity is corresponding with the gap between two steel-plastic composite pipes, if when there is infiltration, water can only flow to T-shaped cavity from gap, can not flow to other place, strengthen sealing effect.
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 when carrying out pressure groove processing, 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.
