Q: How to make a rubber tube requires flow: Rubber pipes are made of high pressure rubber hose and low pressure rubber hose.Low pressure rubber hose is made of inner rubber, cloth, winding (cloth, winding layer number), outer rubber. High temperature processing and vulcanization.

Q: Why should the high pressure hydraulic tube peel off the outer skin?: There are two reasons for stripping. One is that the inner diameter of the sleeve is the standard series, and that the outer diameter of the hose is not suitable, so it must be peeled. Two, after stripping, the sleeve can be directly pressed on the steel wire layer. The connection is reliable, and it is not easy to pull out.Whether or not to peel the rubber depends on the fit between the hose and the sleeve. Not every rubber hose is to be stripped.

Q: How to prevent leakage of rubber joint check valve?: As the valve body is particularly flexible, to ensure maximum resistance to back pressure at the same time to minimize water head, and some only one centimeter water head can be opened, so that the valve emissions and back resistance to achieve a perfect unity.

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

Q: Will the electric water heater be well connected with metal hose or hose?: For electric water heater, now the industry is required to use PPR pipe to its inlet and outlet for welding, on the one hand, long service life, can effectively prevent the water heater inlet and outlet leakage;

Q: Is the rubber pipe joint installed in the middle of the pipe and pump for shock absorption?: According to the pumping station environment, the noise source is not close to the pump house for sound insulation treatment, the noise of the pumping room will be taken sound absorption / sound insulation treatment, doors and windows should do sound insulation treatment, and so on.

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: How should we distinguish between the silicone hose and the rubber tube?: Silicone hose is relatively soft, flexible, and looks better than other rubber tube gloss, color is mostly red, blue, translucent and other colors. Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black.

Q: The rubber is sheathed on the metal cylinder. How can it be connected?: With the combination of metal rubber is coated with adhesive before production and rubber vulcanization shaping, you can use this temporary experiment 502 geliahao for glue or adhesive, but the disadvantages of this thing with winter is not strong, the metal surface must be clean

Q: What with the appropriate suction tube Dichotomanthes tube and rubber machine: The bellows are extruded by the extruder, and the winding tubes are wound in circles
