Q:How to detect the reliability of rubber hose

Bending test: after bending the hose to a certain extent, measure the minimum outside diameter of the bending part and the ratio of the outside diameter before bending, the passing capacity of the steel ball and the bending force when the tube is pressurized.

Q:How to replace natural gas hose? Steps?

Turn off the gas main valve, that is, the gas cooker switch;Unscrew the ends of the hose;Hose removal;Replace the new hose;Reopen the valve.

Q:How to make sure the rubber hose will not be worn off?

The sole judgment is as follows at the end of the rubber bottom or tendon tendon end methods: look at the color, color is usually translucent, while the rubber bottom is not.

Q:How to install the water hose and do you use the tape? Or direct installation?

The pipeline key fixed: if it is not fixed, at the disengaged joint under the action of water pressure, or joint fixed point is the best, because only the most effective joint will be fixed, hard tube and building reliable fixed connection, can guarantee the normal use of the time to extend the hose.

Q:What do you mean by "DN" on hydraulic hose?

Hydraulic hose temperature: -40 ~ 120 DEG C, product specification range: DN2.5mm ~ DN305mm.

Q:How do I get the hose for the gas cooker?

Clean the stove inlet, then hose joints and joints into the stove over the red, with a pipe clamp or hose clamp hoop.

Q:Why should liquefied petroleum gas use strong rubber hose and liner?

These gases on the rubber has a certain corrosion, swelling (not resistant to oil will speed up swelling), aging effect, liquefied petroleum, so choose rubber seal to consider oil resistance, corrosion resistance, swelling. Petroleum gas is corrosive to ordinary rubber pipes and gaskets and easy to cause air leakage. Therefore, it is necessary to use rubber pipes and gaskets with strong oil resistance.

Q:What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?

Siphon principle: that is the principle of connected devices, plus in a closed container, the pressure on the liquid, everywhere equal. The siphon is filled with water, there is no gas, the water level of the water inlet is high, and the water outlet is closed with palm or other objects. The pressure is equal everywhere. When all are arranged, the water outlet is opened, although the atmospheric pressure on both sides is equal, the water level at the water inlet end is high and the pressure is large, and the water inflow is continuously flowed out of the water outlet.

Q:The difference between the rubber pipe and PE pipe?

Rubber tube, this product is a rubber tube products, with oil, acid, alkali, heat, pressure and other characteristics of the transmission and attract rubber hose. Most rubber tubes are non-toxic and environmentally friendly, but some of the higher demand oil and gas pipes add flame retardants to the rubber material. The flame retardants contain toxic and harmful substances which can have a slight effect on the human body and the atmosphere. Rubber tube and characteristics; physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties. Apply to supporting electrical appliances, electronics, furniture, equipment, toys, hardware, medical equipment, sporting goods, audio, lighting, machinery, automobiles, motorcycles, ships, aviation, and other fields.

Q:Natural gas can be connected to a gas cooker. Can rubber tube be used?

No, it's not safe. To purchase national standards products with 3C certification.
