Q:The basic buret is a rubber tube is inlaid with a glass bead to replace glass piston. Why this burets cannot be used to install Potassium Permanganate solution?

The rubber tube can be Potassium Permanganate oxidation

Q:What is the difference between the precast beam of the bridge and the method of pulling out the rubber tube after pouring the concrete? What's the difference between design and calculation?

Construction process, in order to avoid concrete into bellows, influence later wear steel strand, construction units generally use PVC and other rubber tube into bellows, in order to double insurance, don't let concrete into. Its length is certainly larger than the length of bellows (750mm at one end for easy operation)

Q:How to prevent leakage of rubber joint check valve?

Is an integral structure, one hundred percent high quality elastic rubber material, built-in reinforcing fibers, except hooped external stainless steel hoop, its interior does not contain any metal accessories, will not rust corrosion, and wear resistance strong, no mechanical failure worries, no maintenance. Because it is used in butyl rubber, so that the wear resistance is particularly strong with the traditional water pressure automatic opening and closing are very safe and reliable, no noise, no need of manual operation, so no need to maintain his application scope is wide.

Q:What is the essential difference between rubber expansion joint and rubber joint?

Nothing different.The metal bellows joint and the rubber soft joint have their respective advantages.Under normal working conditions, there is no problem with rubber soft fittings.If the temperature of the pipe medium is high, the pressure is large and the corrosion is strong, the metal bellows expansion joint must be chosen in this case.

Q:The main features of Linatex rubber tube or what are the characteristics?

The main characteristics are excellent wear resistance, high impact resistance, high pressure resistance

Q:Between the two flanges in the middle of the rubber tube, what is the name of the connection?

The product is mainly composed of inner and outer rubber layer, cord fabric and steel wire ring. It is formed by vulcanizing with metal flange at high temperature and high pressure

Q:What is negative pressure rubber shock proof joint? Is vacuum piping available?

Negative pressure resistant rubber shock joint is simple product requirements than the general negative pressure resistant rubber joint rubber joint is much higher, simply can't stand the pressure, for example the pipe diameter is 0.1kg pressure, rubber tube will suck flat, so with the outward pressure pipeline is completely different, negative pressure, diameter must be increase the pressure guide tube, negative pressure diversion tube also is what we usually say is a carbon steel pipe in the shock absorber rubber hose diameter, but joint diameter than the original diameter, the pressure guide tube, shock absorber rubber hose will not be sucked flat, so that the original vibration isolation and shock proof box the expansion effect is not affected, only the affected joint is slightly smaller diameter.

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:Standard for implementation of type KXT-1 rubber joints

This product can reduce vibration and noise, and can be compensated by thermal expansion and cold contraction due to temperature changes. It is widely used in various piping systems. Rubber joint manufacturing standard CB-T 965-95 CJT208-2005 to take over the compensation rubber flexible rubber joint CJT 3013.1-1993 KST flexible rubber joint

Q:Why does Br2 corrode rubber tubes?

Br2 bromine gasBr2 bromine element at room temperature is dark brown liquid, soluble in water, 100g water can dissolve about 3G bromine. Highly volatile, toxic, steam strongly stimulate the eyes, mucous membranes and so on. The water solution is called bromine.
