Internal lining pipe is made due to the use of polyketone (PK, Polyketides) material in the production method of the internal lining pipe of the application, because
This long-term safety temperature in use is 120 degrees Celsius.Therefore internal lining pipe will not be caused to fall off bulge, leads to accident.
According to the accompanying drawings to the detailed description of the specific embodiment of the application, those skilled in the art will be more
Above-mentioned and other purposes, the advantages and features of the application are illustrated.
Description of the drawings
Some specific embodiments of the application are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter.
Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that these
What attached drawing was not necessarily drawn to scale.In attached drawing：
Fig. 1 is the flow chart according to the production method of the internal lining pipe of the application one embodiment.
Specific implementation mode
Please refer to Fig. 1, in one embodiment of the application, the production method of internal lining pipe includes the following steps：S1：Pass through single spiral shell
Bar extruder makes polyketone internal lining pipe base material；S2：By isometrical compressor by the outer diameter of the polyketone internal lining pipe base material from first
Size compression obtains polyketone internal lining pipe semi-finished product to the second size；S3：The polyketone internal lining pipe semi-finished product are inserted into outer tube；And
S4：The polyketone internal lining pipe semi-finished product are heated, so that the outer wall of the polyketone internal lining pipe semi-finished product is close to the inner wall of the outer tube, obtains
Obtain polyketone internal lining pipe finished product.
For example, using polyketone as high molecular material, by the single screw extrusion machine of special designing, further through poling repeatedly
Composite testing, it is smoothly compound to polyketone internal lining pipe progress poling, it is final to determine that tube outer diameter is determined as 63.5mm, wall thickness 3mm.It is logical
A specific wheeled isometrical compressor mechanical is crossed, tube outer diameter is compressed to 60.5mm.After smoothly penetrating internal lining pipe, further through specific
Insulated building heat expansion process, make insulated building that 80 degrees Celsius of room temperature, tubing be kept to restore expansion by 3 hours outer diameters,
So that polyketone liner pipe outer wall and steel oil pipe is tightly bonded, bushing pipe is avoided to fall off, to metal oil under 150 degrees Celsius of temperature environment
After the polyketone bushing pipe flange processing at pipe both ends, a kind of fire resistant anticorrosive liner oil pipe is ultimately formed.In this application, the first ruler
Very little is 63.5 millimeters, and the second size is 60.5 millimeters, wall thickness is 3 millimeters, but is not limited thereto.In addition the temperature of heating process
It it is 80 degrees Celsius, heating time is 3 hours, and flange environment temperature is 150 degrees Celsius, is also not limited.Art technology
Personnel can change above-mentioned parameter according to actual demand.
In actual fabrication, if because the gel for generating air bubble type when polyketone raw material can cause to squeeze out containing moisture is existing
As needing that processing, 80 degrees Celsius of dryer settings temperature, drying time 4-8 hour is dried to raw material before extrusion.But it is dry
Dry temperature and drying time are not limited thereto.
In order to which polyketone internal lining pipe base material is more smoothly made, in one embodiment of the application, in particular process temperature
Under degree control, the polyethylene wax of addition 2% has reached and smoothly squeezes out in polyketone as additive and lubricant in polyketone raw material
The purpose of bushing pipe base material.
In one embodiment of the application, polyketone material extrusion screw rod is single screw rod, and overall length is divided into processing sections, compression section and metering
Section, there are mixing sections for full screw rod, make full flight screw.Screw design parameter：Draw ratio (L/D) 26 or more；Compression ratio (C/R)
2.5-3.0；Screw pitch：1D；The wide 0.1D of screw thread；Feeding section groove depth 0.15-0.2D；The segment length that feeds 7D；Compress segment length 14D；Meter
Measure segment length 7D.
Extrusion step and the temperature setting such as figure below of polyketone internal lining pipe base material are made by screw extruder：
| Temperature is set | 60-80 | 240 | 240 | 240 | 235 | 235 |
| Position | Feeding section 1 | Feeding section 2 | Compression section 1 | Compression section 2 | Metering section 1 | Metering section 2 |
Polyketone material is more sensitive to temperature, can aggravate hinge reaction at high temperature, or even will produce gel.The above processing
Temperature setting is the optimal process temperature summed up by numerous experiments, and when extrusion needs to control, and otherwise will appear raw material burning
Burnt phenomenon.
" flange " technique described herein refers on the planar section or curvature portion of blank, utilizes mold
Effect is allowed to be formed with the straight wall of certain angle or the forming method of flange along closing or not closed curved edge.Flange is
One kind of Sheet Metal Forming Technology.There are many type of flange, and sorting technique is also not quite similar.Wherein it can be divided into elongation type by deformation properties
Flange and compression-type flange.
Internal lining pipe is made due to the use of polyketone material in the production method of the internal lining pipe of the application, therefore long-term safety uses temperature
Degree is 120 degrees Celsius.Therefore internal lining pipe will not be caused to fall off bulge, leads to accident, it is resistance to has mended 90-120 degrees Celsius of pipe high temperature resistant
Corrode the blank of internal lining pipe.
The preferable specific implementation mode of the above, only the application, but the protection domain of the application is not limited thereto,
Any one skilled in the art is in the technical scope that the application discloses, the change or replacement that can be readily occurred in,
It should all cover within the protection domain of the application.Therefore, the protection domain of the application should be with scope of the claims
Subject to.
