Q:The basic buret is a rubber tube is inlaid with a glass bead to replace glass piston. Why this burets cannot be used to install Potassium Permanganate solution?
The rubber tube can be Potassium Permanganate oxidation
Q:Three yuan ethylene propylene rubber hose, hydraulic oil and oil?
Finally, NBR (Ding Jing rubber), ACM (acrylate), FKM (FKM) can be non polar medium.
Q:Faucet hose connection problem
Ball valves can be made, but easy to leak. More than a few times to install a feeling, when the screw does not use brute force ah.
Q:What's the metal hose for fire fighting?
Fire hose is an important component of modern industrial equipment connecting pipelines. The metal hose is used as wire, cable, automatic instrument signal wire, cable protection tube and civil shower hose, specifications from 3mm to 150mm. Small caliber metal hose (inner diameter 3mm-25mm) is mainly used for precise optical ruler sensing line protection and industrial sensor line protection.
Q:How much is a gas hose a metre? At least 1 meters, 5 safe?
1, liquefied petroleum gas will soften the ordinary rubber tube, please use special rubber tube.2, often check and clean hose, found aging, cracking, burn, rat worm bite marks, should be replaced immediately. It is recommended that the hose be replaced in two years under normal conditions.3, gas hose length of not more than 2 meters, after passing the place is not allowed to have electrical appliances.4, hose do not close to the stove surface, so as not to be flame barbecue.5, the hose does not cross the wall, doors and windows.6, do not press or fold the hose, so as not to plug, affecting the continuous gas supply.At the interface, and appliance, 7 hose valve, please use the pipe truss, to prevent the shedding of leakage.
Q:What is the method of making large diameter rubber joint?
Rubber joint also known as shock absorber, shock absorber throat, the main function is to shock absorption, noise reduction, protection of the pipeline, compensation pipeline expansion, cold caused by displacement.Its structure: both ends are two carbon steel flanges, the middle is rubber shock absorption part.
Q:Is flexible rubber joint and telescopic device a kind of thing?
The utility model discloses a pipe expansion device, which is a connecting piece which is compensated by the size change caused by thermal expansion and cold contraction in the pipe connection. There are two kinds of pipe expander, one is rubber pipe telescopic device, and the other is metal pipe telescopic device.
Q:Flex rubber joint installation skills, what are the materials of rubber soft joint?
Flexible rubber joint is normal for medium temperature of 0-60 DEG C usually water medium such as oil, acid, high temperature and other corrosive and texture should be selected under the peace situation should be relatively Tenai data can not be blindly on rubber joint or universal.
Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.
The pressure of the aluminum pipe is relatively small. "Again, when the aluminum pipe is too soft, it is easy to be flattened.".. Rubber tubes will decay if they are used! Withstand pressure is also high!
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?
After so many years of consulting, you are the first to ask the hose through the wall. In real life, there are many hoses that go through walls.
