Q: Between the two flanges in the middle of the rubber pipe, what is the name of the connection?: Rubber flexible joint is also called rubber flexible joint, flexible rubber joint, flexible rubber joint, rubber shock absorber and so on.

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?: Corrugated pipe is included in the design of the amount of engineering, the role is: reserved strand space. Its length is calculated when the work length of the steel strand.

Q: How can I keep the rubber tube for stethoscope?: First of all, why would the stethoscope sound by the hollow box head, the heart beat (vibration) into the vibration of the hollow box leaves, (also caused by internal air vibration), thus forming the sound of the heart.

Q: Can the rubber hose for the LPG cooker and gas cooker be general?: The characteristics of the 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.

Q: How do the rubber tubes fit into the galvanized pipe?: If the rubber tube is outside the galvanized pipe, when the rubber is ordered, the inside diameter shall be greater than the outer diameter of the galvanized pipe. If the rubber tube is inside the galvanized pipe, when the rubber is ordered, the outer diameter of the rubber pipe will be galvanized and the inner diameter of the galvanized pipe will be inside

Q: Which is better for binding files with rubber tubes and cotton threads?: X rubber hose and rubber band type light aging fast, not suitable for long-term preservation, cotton is afraid of water and insects

Q: Why should liquefied petroleum gas use strong rubber hose and liner?: In order to remind people of the leakage of liquefied petroleum gas in a timely manner, the processing plant often mixes a small amount of foul odor mercaptan or thioether compounds into liquefied petroleum gas, which is the source of special odor.

Q: What's the rubber sleeve of the expander?: The expansion device is also called expansion joint, expansion joint, compensator and expansion joint. The expansion device is divided into steel telescopic device, rubber telescopic device and stainless steel telescopic device according to the material. Expansion device capable of axial expansion in a certain range, the offset can overcome different axial pipe butt within a certain angle and produce, installation and convenient disassembly pipeline valve greatly, in the pipeline to allow expansion in free expansion, once over its largest expansion amount rise to limit, to ensure the safe operation of pipeline the. Mainly for the protection of the safe operation of the pipeline, has the following functions: compensating absorption pipeline axial and transverse and angular deformation; absorption equipment vibration, reduce the vibration on the impact of pipeline equipment; deformation of the pipeline, absorb seismic subsidence.

Q: What is the rubber sleeve flange connection sleeve?: Ram direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle valve flange. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.

Q: The difference between the rubber pipe and PE pipe?: The appearance of the native HDPE is milky white and is somewhat translucent in the narrow cross section. PE has excellent properties that are resistant to most life and industrial chemicals. PE pipe welding, butt welding of PE pipeline, the method provides the highest reliability and the diameter of the range and pressure process: the end of the heating tube, using a tool called mirror contact pressure and temperature under the definition of "". The ends are contacted rapidly and remain under pressure during cooling. A medium density polyethylene pipe and PE pipe with high density polyethylene pipe. Divided into SDR11 and SDR17.6 series according to the wall thickness. The former is suitable for transporting gaseous artificial gas, natural gas and liquefied petroleum gas. The latter is mainly used to transport natural gas.
