Product details: cord rubber hose

1. Product structure:

It consists of an inner rubber layer, 1-2 layers of cord or synthetic fiber braided or wound reinforcement, and an outer rubber layer.

2. Product Features:

The rubber hose has the advantages of small outer diameter tolerance, excellent oil resistance, heat resistance, light weight, soft and durable body, etc. The minimum burst pressure of the hose is four times the working pressure.

3. Product use:

Fiber braided (or wound) rubber hose can be used for diesel engines to transport gasoline, kerosene, diesel oil and other mineral oils. It has excellent oil corrosion resistance and can transport oil below 100 °C. The ambient temperature of the rubber hose is not lower than -30°C; it is also suitable for other petroleum-based, oil-water emulsion liquids, compressed air and inert gas media.

4. Main products:

Fiber braided (or wound) special fuel hose for oil transportation and air fiber braided and wound air pressure special hose for air delivery. The design pressure is 10-15kg/C㎡, and the length of the braided hose is large, up to 100 meters.

6MM, 8MM, 10MM fiber braided steam hose, used to transport saturated steam (pressure 0.39MPa) or superheated water not higher than 150°C. 6MM, 8MM, 10MM oxygen (red appearance, pressure 1.47MPa), acetylene hose (black appearance, pressure 0.29MPa). 16MM CNC flame cutting machine rubber hose (pressure 2.45MPa), the rubber hose has high pressure, long service length, small bending radius, safe and reliable, and is used to transport oxygen, acetylene gas, and compressed air for 8.8M large-scale equipment; it can be customized according to requirements Rubber hoses of various pressure specifications, large-diameter tubes and special-shaped tubes, telescopic tubes, elbows, pure rubber hoses, fiber-wound sandblasting hoses, fiber-wound acid-base hoses, etc.

How to flang the corrosion-resistant PTFE tube

In the process of using corrosion-resistant PTFE tubes, for a wide range of applications, it is necessary to assemble and flanging the pipe fittings, so how to assemble and flanging?

When the corrosion-resistant PTFE pipe is assembled, an asbestos pad of appropriate thickness should be added to the interface to meet the overall size requirements after lining. The assembled seamless steel pipe should be sand blasted to remove the rust on the inner wall, and then the inner cavity of the pipe should be blown clean with compressed air. Insert the tetrafluoroethylene tubing into the steel pipe. If some tetrafluoroethylene tubes are not round and cannot be inserted, the tetrafluoroethylene tubes should be heated with hot water, steam or intermediate frequency heating furnace, and the heating temperature should not exceed 100 °C.

1. When cutting the PTFE tube, consider the length of the flanging. Generally, a length of 35-40 is reserved above the welding ring surface.
2. Before flanging, put an asbestos Bajin gasket on the tetrafluoroethylene pipe.
3. The flanging of the PTFE tube is carried out in two steps. The first step is to turn it into a bell mouth. The mold used for this flanging is a tapered cast aluminum part.
4. When flanging, use an oxygen-acetylene flame to heat the mold. Measure the mold temperature with a semiconductor surface thermometer. The mold temperature should not be too high, and the temperature should be controlled between 260°C and 280°C.
5. When flanging, slowly press down the heated conical mold. When the mold is pressed to the edge of the welding ring, do not press it again. At this time, use water to cool it. Remove the mold when it cools to the ambient temperature. .
6. The flanging in the second step makes the nozzle further plasticized. This time the mold is flat, and the heating method and temperature control of the mold are the same as the first step. After heating, the mold is slowly pressed down and completely flattened, then cooled with water to ambient temperature, and then the mold is removed.
