Description
Technical field
The utility model belongs to pressure piping field, especially a kind of corrosion protection pressure lining pipe.
Background technique
In the industries such as heavy chemical industry, chemical fertilizer, petroleum and petrochemical industry, smelting iron and steel, carry the occasion of corrosive fluid medium, metal tube is because can be corroded and cannot use; Therefore in this kind of occasion, usually need to use fluoroplastics lining pipe, and there is following shortcoming in existing fluoroplastics lining pipe: 1. existing fluoroplastics lining pipe because of installation can cause install wafer type butterfly valve can not open completely, special-purpose cushion loop device must be bought in addition coordinate and could use, improve purchase cost; 2. existing fluoroplastics lining pipe carries out two ends flange because adopting pushing PTFE plastic tube, not resistance to high vacuum, non-refractory and working life short; 3. existing fluoroplastics lining pipe carries out two end flange face flange again after adopting pushing PTFE plastic tube to draw in steel shell, the impact of expanding with heat and contract with cold can not be resisted, when temperature changes suddenly, because PTFE plastics are different with the cold and hot swelling system of steel, angular rotation of flange place, PTFE plastic pipe two ends is easily pulled off; Therefore should improve prior art.
Summary of the invention
For the problems referred to above, the utility model aims to provide a kind of resistance to high vacuum, high temperature resistant, cost is low and the corrosion protection pressure lining pipe of long service life.
For realizing this technical purpose, the utility model provides following technological scheme:
A kind of corrosion protection pressure lining pipe, be made up of steel tube, steel wire, flange and PTFE backing layer, the inwall of described steel tube is provided with steel wire, and the import and export of described steel tube is equipped with flange, and described PTFE backing layer is made up of flow-passing surface material.
As further program of the utility model: described steel tube is steel skeleton, and steel tube is made up of carbon steel or quality carbon steel material.
As further program of the utility model: described steel wire is for strengthening steel skeleton, and described steel wire is made up of carbon steel material, and steel wire adopts diamond structure.
As further program of the utility model: described flange is made up of carbon steel material, and flange adopts flared type forge piece of step type structure.
As further program of the utility model: described PTFE backing layer adopts mould pressing technology to make by PTFE powder, and PTFE backing layer and steel wire melt as a whole.
Compared with prior art, the beneficial effects of the utility model are: do structure is improved to form flared type forge piece of step type structure to entrance end flange on protofluorine plastic lining pipe, corrosion protection pressure lining pipe import and export is increased also, and fillet is excessive, thus the butterfly valve when installing butterfly valve on flange port can be opened and closed arbitrarily, special gasket ring need not be increased, reduce user's purchase cost; Protofluorine plastic lining pipe improves backing layer, backing layer adopts PTFE stamping of powder (equipressure) lining forming technique, enhancing steel wire is welded with at steel pipe inner wall, when PTFE powder is shaping in steel wire embedding plant PTFE powder layer, after sintering, steel wire and plastic melting are integrated.The utility model not only can resistance to high positive pressure, resistance to vacuum, high temperature resistant, corrosion-resistant effectively, and long service life, structure are simple, practical, in use can eliminate the impact of expanding with heat and contract with cold and bringing.
Accompanying drawing explanation
