It is in conformity with the internationalstandard DIN-EN 857 2SC. Tube : Oil resistant synthetic rubber .Reinforcement :two high tensile steel wire layers 2 w .Cover : Abrasion and weather resistantsynthetic rubber. It is widely applied to the application with the temperatureranging from -40℃to 100℃.
- Q:The small hose attached to the grease gun is coarse or fine at the joint
- For sealing, according to the maze principle, the smaller the pitch, the number of threads, that is, the more layers, the better the sealing effect, not easy to leak oil, significantly better than the rental thread.
- Q:Diameter 127mm steel pipe, and diameter 127mm rubber hose how to connect?
- A metal ring is sheathed inside the rubber tube, and the rubber tube with the metal ring is sheathed into the metal tube so that they can come into close contact with each other. In brief, the metal collar and the steel pipe hold the rubber tube in the center. I wonder if you understand. The outer diameter of the metal ring is about 111~119mm. It's hard to say how specific it is.
- Q:What are the gas hoses?
- The stainless steel is expensive, 40 yuan set.The rubber is cheap, 10 yuan a set.Where do you come from? I don't know. In our Shanghai gas, this price includes the labor cost of the installation to you. In other words, fix it directly for you.
- 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?
- The principle of communicating devices can be explained by liquid pressure. If the same liquid is contained in a U glass tube, a small liquid AB is conceived at the center of the bottom of the communicating device. If the liquid is stationary, it does not flow. The pressure of the liquid in the left tube toward the right side of the liquid AB must be equal to the pressure of the liquid in the right tube toward the left of the liquid AB. Because in the communicating vessel is filled with a liquid, the same two liquid column density, according to the formula of P= P GH liquid pressure that only when both sides is equal to the height of liquid column, the liquid column is equal to the pressure on both sides of the liquid film AB. Therefore, in the case of no flow of liquid, the liquid level in each vessel of the communicating device shall be kept flat. (ideal model method) the connecting device is characterized in that the liquid level in each container is flat only when the same liquid is contained in the container. If the container is tilted, the liquid in each container is about to begin to flow. One end of the liquid column flows to the lower end of the liquid column and stops flowing until the liquid level in each container is normal. As with rubber tube two glass tubes connected together in container with a liquid, which will be a fixed tube, the other tube up and down or tilt, can see the two tube level in stationary phase remained flat. The connecting device is provided with the same liquid, but the pressure on the liquid surface is unequal, and the pressure difference of the liquid surface is equal to the pressure difference produced by the liquid level difference of the two container of the communicating device.
- Q:What happened to the soft rubber flat?
- A slightly heated or pressurized medium will return to its original condition.
- Q:What are the properties of stainless steel metal hose materials?
- The stainless steel metal hose is made up of corrugated pipe, stainless steel braid net and two ends joint.
- Q:Rubber soft joint, what brand of good, the best price is more reasonable. Don't say anything expensive.
- The rubber joints produced throughout the country have the longest history in Shanghai, and have the characteristics of the type and sales volume of Gongyi city. They have been sold in the plumbing market all over the country
- Q:What are the types of metal hose couplings?
- DKJ jointStructure and characteristics:The DKJ card sleeve type metal hose joint can connect the steel pipe without the screw and the hose, and save the thread setting process, just screw the screw in;The metal joint is made of zinc alloy. The surface is zinc plated, sanded or chrome plated. The structure is compact and the strength is high. The steel pipe and the metal hose are connected reliably, and the appearance is beautiful;The metal fittings are jacketed to connect the metal hose to the non threaded steel tube;Suitable metal hose: JS, JSH, JSB, JSHG;Adaptation: steel thin steel wire pipe, black, tin pipe (water, gas);When choosing DKJ card type metal joint, please pay attention to the specification and size of the connecting pipe hose.
- Q:Is flexible rubber joint and telescopic device a kind of thing?
- The main features of metal pipe telescopic device are telescopic, large compensation and high temperatureUnder great pressure.And flexible rubber joint is a product!
- Q:What material is the rubber joint used in the desulfurization pipeline? What's the difference?
- If you choose the ordinary material or other special materials, it will inevitably be broken. Because of the different materials of rubber joints, the application environment is different.
