Q:Faucet hose connection problem: The buried water pipe is outside the wire, you can use the inner home angle valve. When installing, pay attention to the rubber ring in the metal hose. The gasket should be put away. It is better to buy the transparent rubber ring and the metal hose of that kind of gasket, and pay attention to the length.

Q:What are the types of metal hose couplings?: DKJ jointStructure and characteristics:The DKJ card sleeve type metal hose joint can connect the steel pipe without the screw and the hose, and save the thread setting process, just screw the screw in;The metal joint is made of zinc alloy. The surface is zinc plated, sanded or chrome plated. The structure is compact and the strength is high. The steel pipe and the metal hose are connected reliably, and the appearance is beautiful;The metal fittings are jacketed to connect the metal hose to the non threaded steel tube;Suitable metal hose: JS, JSH, JSB, JSHG;Adaptation: steel thin steel wire pipe, black, tin pipe (water, gas);When choosing DKJ card type metal joint, please pay attention to the specification and size of the connecting pipe hose.

Q:Carbon dioxide gas shielded welding torch wire feed hose joint, that steel wire can not be drawn out, how to solve it, with welding?: Some of the torch wire feeding hose can not be replaced, it is fixed dead, such as Xiong Gu, Lincoln's self shielded flux cored wire, welding torch.

Q:Acid burette and how to distinguish the basic buret: Alkali: rubber tubes. Acids: glass tubes (remember: NaOH and glass reactions. So rubber)

Q:How much is a gas hose a metre? At least 1 meters, 5 safe?: General 10 or so can be, the length of 1 meters to 1.5 meters can be, too short, unsafe, it makes sense.

Q:What is negative pressure rubber shock proof joint? Is vacuum piping available?: With high pressure, good elasticity, large displacement, balance pipe deviation, absorbing vibration and noise reduction effect, convenient installation, but also can greatly reduce the noise and vibration of the pipeline system, which can solve all kinds of line interface displacement fundamentally, axial expansion and concentricity problems, mainly installed in the pump inlet the vacuum pump inlet, or large, can solve the 100% rubber joint suction flat phenomenon.

Q:Why does Br2 corrode rubber tubes?: Bromine elements need to be sealed with water to prevent steam escaping and harm the human body. Oxidizing, there are a variety of variable valency, under normal temperature and weak water reaction, generating hydrobromic acid and bromate. Heating increases the speed of reaction. Hydrobromide is a strong acid with an acid stronger than that of hydrogen chloride. Bromine is commonly used in organic synthesis.

Q:Hose connector JB1885-77 what is the standard?: The reason of high pressure hose joint leakage are the following: "a" ring aging or deformation caused by leakage; the "C" ring assembly is not in place, the two plane connection or "C" uneven pressure ring is cut caused by leakage; "a" ring without compaction, the elastic deformation caused by leakage; the "C" ring spigot groove deep caused leakage. In this regard, the need to re select the same diameter and thick section "C" ring, can also be provided with a sealing plane rabbet groove of cutting or grinding, in order to reduce the rabbet groove depth, the "C" ring has enough elastic deformation (compression should be between 0.35-0.65mm).

Q:The gas water heater uses metal pipes and rubber pipes: Gas water heater using metal pipe, good heat resistance, no aging!

Q:Three yuan ethylene propylene rubber hose, hydraulic oil and oil?: First of all, three yuan ethylene propylene rubber is non-polar, oil is non-polar, as for hydraulic oil well, there are many kinds of polar hydraulic oil and non-polar hydraulic oil.
