High Quality Shaped Straight Pipe

Shaped straight pipe
PTFE liner tight straight pipe and pipe fittings
Manufacturing process: the first number of PTFE membrane around the mold, then wire (phi) 0.5 1 mm by spiral winding on the PTFE film, outside the wire winding again after several layers of PTFE membrane, the last in the furnace for sintering forming. In this process of PTFE lining tube and inner surface is smooth, The outer wall due to the volume of steel wire and its elastic force, form a spiral line. Will it lining into the steel pipe and the PTFE liner tube outer wall and the gap between the steel tube wall filling filling resin (residual air discharge). This kind of resin filled with steel tube tightly stick together. At the same time, it can be tightly wrapped in spiral PTFE liner outside walls, filling resin after curing, has formed the lining and the outer wall corrugated occlusion of spiral corrugated. The combination of this structure, similar to the nuts and bolts. On one hand it can make the heat bilges cold shrink of PTFE lining effective restriction and compensation; On the other hand, the use of the rigidity of the steel wire obviously improve the ability of PTFE lining resistance to negative pressure.
Size specifications: DN25 ~ 200 mm
Working temperature: - 50 ~ + 230 ?
Pressure of work: 0.5 ~ 1.6 Mpa
PTFE push (squeeze) pressure pipe line straight tube
Manufacturing process: first, using imported PTFE, PFA, FEP, PVDF powder, push (squeeze) pressure into the pipe, then it forcibly dragged into the seamless steel tube (liner diameter slightly larger than 1.5 2 mm steel pipe diameter), the formation of no clearance lining.
 In order to eliminate stress, put it in the oven, heating temperature 230 ?, make it adapt to used in the temperature under 230 ?. At the same time, push (squeeze) pressure tube axial tensile strength is better than coil tube obviously. This pipe has ideal positive and negative pressure resistance ability.
Size specifications: DN25 ~ 300 mm
Temperature: 100 ~ + 230 ?
Role stress: 0.09 ~ 1.6 Mpa
The pipe fittings with fluorine plastic (PFA, FEP, PVDF, PTFE) as raw material, by moulding forming, 3-7 mm, the thickness of the lining has good ability of resistance to positive and negative pressure.
Size specifications: DN25 ~ 500 mm
Using pressure: 0.09 ~ + 1.6 MPa
Temperature: 100 ~ + 230 ? (PFA) - 100 ~ + 200 ? (FEP) - 100 ~ + 200 ? (PVDF)
At present, the domestic push (squeeze) pressure the diameter 300 mm diameter of PTFE tube, PTFE lined pipe of wire wrapped the ideal size is only 200 mm. To solve the DN25-500 - mm liner straight pipe and pipe fittings of positive and negative pressure resistance problem, we adopt the following lining process; The PTFE liner, According to a certain distance setting outsourcing PTFE metal support ring (6) - 16 mm, wall made of corrugated, on the one hand, fixed support ring; On the other hand make the heat bilges cold shrink of PTFE lining better compensation, make the pipe has good ability of resistance to positive and negative pressure.
Menstruation specifications: DN25 ~ 500 mm
Temperature: 100 ~ + 230 ?
Using pressure: 0.09 ~ + 1.6 MPa
