Q: Latex tube, rubber tube, silicone tube, which three of the best tightness?: Ding Ji rubber: usually used as a silicone hose material used, in general, the sealing ability of silicone hose is better than the rubber hose. So, in life or in the industry need to seal the tube will take into account the silicone hose.

Q: What is a rubber core pulling method?: The hose shall be filled with water or gas at a pressure of 0.5 0.8N / mm before pouring concrete. At this point, the hose diameter can be increased by about 3mm. When pouring concrete, the vibrating bar should not touch the hose, and should check the pressure of the water meter regularly. If there is any change, the pressure must be filled.Smoke tube longer than tube core pulling slightly later. Before the pipe is pumped, the water is lowered and the pipe section is reduced, and the pipe can be drawn away from the concrete. The order of pumping is usually first, then first, then first, then straight.

Q: What are the categories of hose?: According to the compression status: pressure hose; suction hose; pressure suction hose (drain suction hose)

Q: What's the rubber sleeve of the expander?: Expansion rubber flexible joint, installation of the flange sleeve telescopic device.

Q: Three yuan ethylene propylene rubber tube covered with nylon PA66, what glue can not afford the layer?: The engine parts including inlet system and fuel system, such as engine cylinder cover, solar term door, air filter machine shell, vehicle air horn, automotive air conditioning hose, a cooling fan and a casing, a water inlet pipe, brake oil tank cover and irrigation, etc..

Q: Petroleum gas has a corrosive effect on ordinary rubber pipes and is easy to cause air leakage. So, what kind of hose must be used?: 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.

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: Do the rubber joint and Y filter need flange connection?: Rubber hose joints are usually externally threaded, and type Y filters are internally threaded and are directly connected to the same caliber.Flange connection also has ah, according to demand

Q: In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?: Silicone hose is relatively soft, flexible, and looks better than other rubber tube gloss, color is mostly red, blue, translucent and other colors.

Q: How can the tightness of rubber tube and metal pipe joint be ensured?: See how much your pipe diameter, diameter is around 10%, the metal pipe is inserted into the 2-3 rubber tube diameters, almost, don't worry, coupled with a hose clamp.
