Q: Can the copper tube of GREE air conditioner be changed into rubber tube?: Unless they are specially made for air, rubber tubes for general industrial and domestic use shall not be used for connecting air conditioners. Because the refrigerant to plastic and other polymer compounds will play "swelling" role, make it soft, expansion and foaming, will make plastic and other polymer materials more easily aging and decomposition. In addition, the refrigerant pipe is not suitable for the environment of high temperature, low temperature and high pressure, and plastic pipes can not be used.

Q: How to determine the parker381 hose joint?: More knowledge extension: PARKER hose assembly pioneered the use of rubber stripping (No-Skive) do not withhold technology, to avoid the damage caused by removing the plastic hose, the maximum prolong its service life. PARKER KBG hose connector realize the skiving integration design, profile design of sleeve internal special pre withhold is the key to reliable connection. No stripping rubber hose, rubber stripping not withhold joints, without withholding equipment adjustment, a perfect combination of PARKER hose assembly.

Q: Is there a tolerance standard for rubber tubes in length?: Generally speaking, the requirements of diameter and wall thickness are more stringent.The diameter is usually the inner diameter of the hose.Generally speaking, the length is not high, and the unwritten rule for foreigners is "+ 2~3mm".

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: How to install the water hose and do you use the tape? Or direct installation?: The pipeline key fixed: if it is not fixed, at the disengaged joint under the action of water pressure, or joint fixed point is the best, because only the most effective joint will be fixed, hard tube and building reliable fixed connection, can guarantee the normal use of the time to extend the hose.

Q: What kind of material is the rubber tube with acid, alkali and high temperature resistance made of?: To acid, but also high temperature resistant material, only silica gel can do. Silica gel has a high temperature resistant material, can be used at 300 degrees high temperature for a long time, instant high temperature can reach 350 degrees. It's Jiao Jiao in the rubber hose.

Q: Why should the water stop strip be joined by heat instead of superposition?: Thermal connection is the safest and most reliable method of joint treatment, but it has certain requirements for technology.

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: Automotive applications of rubber hose: EPDM three yuan ethylene propylene rubber is used in automobile water pipe series. Such as radiators, hoses, air conditioning pipes, etc.. There are some higher performance materials, such as AEM, acrylate, high temperature and so on.

Q: Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons: Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage.
