Q: What is the function between the rubber pipe joint and the installing pipe?: The action of the rubber pipe joint on the installation of pipes:1. Small size, light weight, good elasticity, easy installation and maintenance.2. After installation, the transverse, axial and angular displacement of the pipe vibration can be absorbed. The pipe is not concentric and the flange is not parallel.3 、 after installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability.

Q: Is the electric water heater well connected with the metal hose?: On the other hand, the utility model can effectively avoid the frequent switch of the water heater power switch because of the two grounding. Therefore, the metal pipe connection does not meet the safety and installation specifications.

Q: Difference between non-standard rubber joint and national standard rubber joint: GB and non standard. GB type rubber joint refers to the material selection and production in accordance with the relevant 02S404 or 02S312 standards of the Ministry of construction, and has strict requirements on flange thickness, flange thickness, diameter and thickness.

Q: What is the essential difference between natural rubber and three yuan ethylene propylene rubber?: The main use of natural rubber natural rubber because of its insulation, plasticity, water vapor barrier, tensile and wear characteristics of strong elasticity and good, widely used in industry, agriculture, national defense, traffic, transportation, machinery manufacturing, medical and health fields and daily life, such as transportation with the tire industry; with the transport belt, transmission belt, sealing rings; medical gloves, transfusion tube; used in the daily life of the shoes, raincoats, warm water bag are rubber as the main raw materials manufacturing, defense on the use of aircraft, artillery, tanks, and cutting-edge technology in the field of rockets, satellites, spacecraft, space shuttle requires a large amount of rubber parts.

Q: Is flexible rubber joint and telescopic device a kind of thing?: The main features of metal pipe telescopic device are telescopic, large compensation and high temperatureUnder great pressure.And flexible rubber joint is a product!

Q: What are the materials used in rubber joints? What are their advantages?: Ordinary air, compressed air, water, sea water, hot water, weak acid, strong alkali, temperature between -20 ~ +115, such as the media with ordinary natural glue can

Q: How can I remove all the flavor on the rubber hose?: After the hot water is directly boiled, wrap it directly with transparent glue

Q: What are the properties of stainless steel metal hose materials?: The stainless steel metal hose is made up of corrugated pipe, stainless steel braid net and two ends joint.

Q: Three yuan ethylene propylene rubber joint (high temperature resistant rubber joint) can withstand high temperature: Because three yuan ethylene propylene rubber does not bear oil, the mechanical strength is low, the price is expensive, therefore it is not suitable to make the oil resistant sealing product.

Q: The pipe of the gas water heater is buried in the wall. It is made of nylon tube and rubber tube. Is it possible to use rubber tube?: With respect to the through wall gas safety management regulations, it is clear that hoses can not be used through walls.
