Q: High pressure hose K type joints KJR32 and KJR31.5D what is the difference between ah, please give us a answer,: K type joint has the distinction between national standard and German standard. In general, 32 and 38 tubes are used more often. The joints used on 32 of the tubes are KJR32 and KJR31.5D. 38. The joints used on the tubes are KJR38 and KJR B40

Q: What is the function between the rubber pipe joint and the installing pipe?: The action of the rubber pipe joint on the installation of pipes:1. Small size, light weight, good elasticity, easy installation and maintenance.2. After installation, the transverse, axial and angular displacement of the pipe vibration can be absorbed. The pipe is not concentric and the flange is not parallel.3 、 after installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability.

Q: How can the rubber joint be classified according to the range of temperature?: A universal rubber flexible joint is suitable for use in water from -15 DEG C to 80 DEG C or in a variety of acid and alkaline solutions with concentrations below 10%.

Q: The difference between hose and rubber tube: Rubber tube: characteristics of rubber tube has 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. In fact, silicone hose is also a rubber tube, resistant to oil, heat.

Q: Is flexible rubber joint and telescopic device a kind of thing?: The utility model discloses a pipe expansion device, which is a connecting piece which is compensated by the size change caused by thermal expansion and cold contraction in the pipe connection. There are two kinds of pipe expander, one is rubber pipe telescopic device, and the other is metal pipe telescopic device.

Q: How to distinguish the true and false corrosion resistant rubber soft joint?: Method for distinguishing true and false corrosion resistant rubber soft joint:Put the rubber joint in the corrosive liquid which needs to pass. One day, 24h can see that the swelling ratio is not more than 5%!

Q: What's the difference between a vulcanized rubber tube and an intake manifold?: The inlet is the passage of air into the engine block, which leads to the cylinder. The valve is mainly composed of a channel designed on the cylinder head, and the inlet is controlled by an air inlet valve at the end of the air inlet

Q: What's the smell of petrol in the car and the trunk?! Especially after a long drive!: Some owners of the gas fuel to add too full, while refueling no leakage, but gasoline but follow the line and into the carbon canister in the tank, the steam release even a gasoline release out, if it is in air conditioning circulating state, the car will be able to smell the smell of gasoline.Solution: as long as the carbon canister inside the gasoline consumed, the excess carbon canister gasoline vapor through the engine negative pressure into the cylinder combustion, there will be no gasoline vapor overflow, and then open the window ventilation is.If you smell the smell of gasoline at the same time there is a pungent rubber flavor, it should be careful, there may be a harbinger of fire, you have to do a good job of checking and preventive measures in advance.

Q: What are the types of metal hose couplings?: DGJ jointStructure and characteristics:DGJ self fixing metal hose joint, it can connect non threaded steel pipe or screw free equipment outlet and hose, and save the thread setting process;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 joint is self - fixing and is used to connect the metal hose to the non - threaded steel pipe or the screw - free equipment outlet;Suitable metal hose: JS, JSH, JSB, JSHG;Adaptation: steel thin steel wire pipe, black, tin pipe (water, gas);When choosing the DGJ self fixing metal hose joint, please pay attention to the specification and size of the connecting pipe hose.

Q: What with the appropriate suction tube Dichotomanthes tube and rubber machine: The spiral tube called spiral steel tube or spiral welded pipe, the low carbon steel or low alloy structural steel strips in a helical line certain angle (called forming angle) rolled into a tube, then the tube welding seam made up, it can be used in narrow strip production of large diameter steel pipe spiral pipe is mainly used in oil.
