Q: Rubber tube in the production process need to wrap cloth, in order to finalize the design, I want to know what cloth is winding cloth, what is the specification, please god!: Widely used in rubber, special rubber, high pressure steel tube; the standard for mud suction hose, hose, hose winding wire; suitable for thick rubber rollers, rubber fender and some rubber expansion force; and the roller for thick water cloth curing wire reinforcement can not reach the the required hardness.

Q: The principle of the common bicycle valve: An elastic thin edge hose is placed below to form the whole of the core. In fact, it is a one-way valve. When inflating the bicycle tyre, the compressed air in the air pump enters the valve core from the hollow part, and the elastic rubber tube is top, and the air enters the tyre.

Q: What are the types of cable metal hose connections?: It is mainly used for connecting the box and hose in place. Open the box in the box and plug into the joint. The external thread joint is fixed with the lock.

Q: What's the cause of a default like a general rubber product?: Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.

Q: Which is safer for stainless steel bellows and rubber tubes for gas pipelines?: Stainless steel bellows, quick fitting joint, good strength. Hose connections are end face seals, greatly improving the reliability of the seal, and some gasket material using PTFE, and its life can be consistent with the tube body, can reduce the number of maintenance or replacement.

Q: The maximum number of joints for a rubber hose is no more than: Shower hose, shower hose, two joints are nominal diameter of: 1/2 inch (4 thiophene) cylindrical pipe thread. Standard component. Hot and cold bath: take a bath with hot water before going to bed every day. The temperature of the water is within the limits of the body's tolerance. After washing, sleep in hot water for 15 minutes. After bathing was out of a sweat, after 3~4 minutes, and then into a basin of cold water or cold shower. Note that the hot and cold bath must be "hot before cold."".

Q: What is the rubber sleeve flange connection sleeve?: Rubber flexible joint flange connection sleeve flange gate valve quota.

Q: Is the rubber pipe joint installed in the middle of the pipe and pump for shock absorption?: Control the noise produced by parts of machinery, equipment, and equipment. The pump foundation of the new pump house should adopt heavy weight to prevent vibration from producing noise. Vibration isolation should be set up with rubber vibration isolating pads to reduce vibration noise. Each pump unit shall be provided with a foundation to prevent resonance. Use "soft" connection as far as possible in the suction pipe and pressure pipe of the pump. Periodic maintenance problems, such as packing leakage, equipment parts loose, serious wear and tear of equipment parts, mechanical vibration and so on, should be repaired in time, thereby reducing noise.

Q: Do the rubber joint and Y filter need flange connection?: To look at the general caliber, less than DN50 also has threaded connection type (i.e., thread), but flange type is more reliable.

Q: M40 and M50, and then the hose is 2 "what does the box connection mean?": M40 and M50 are the specifications of the teeth, but you do not specify the spacing of the teeth.
