Q:Is the electric water heater well connected with the metal hose?

For electric water heater, now the industry is required to use PPR pipe to its inlet and outlet for welding, on the one hand, long service life, can effectively prevent the water heater inlet and outlet leakage;

Q:The rubber is sheathed on the metal cylinder. How can it be connected?

With the combination of metal rubber is coated with adhesive before production and rubber vulcanization shaping, you can use this temporary experiment 502 geliahao for glue or adhesive, but the disadvantages of this thing with winter is not strong, the metal surface must be clean

Q:What is the difference between plastic lined steel pipe and rubber lined steel pipe?

Difference1. processing technology:Rubber lined steel pipe generally adopts the manual adhesive, vulcanizing process (can also be cold bonding operation); plastic lining pipe generally adopts the heating equipment, the overall rotational (tight loose lining, lining, molding, molding) main process steps can be completed by means of equipment. Therefore, the production efficiency of the lining pipe is obviously higher than that of the lining rubber tube.2.: the physical properties of rubber lined pipe due to the inheritance of the excellent properties of rubber, the chemical corrosion and wear resistance, heat resistance is also very prominent, and the plastic lined pipe in addition to resistance to chemical corrosion and lining hose close to the outside, in the wear resistance, heat resistance and adhesive strength are not as lining hose.

Q:What are the types of metal hose couplings?

DGJ jointStructure and characteristics:DGJ self fixing metal hose joint, it can connect non threaded steel pipe or screw free equipment outlet and hose, and save the thread setting process;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 joint is self - fixing and is used to connect the metal hose to the non - threaded steel pipe or the screw - free equipment outlet;Suitable metal hose: JS, JSH, JSB, JSHG;Adaptation: steel thin steel wire pipe, black, tin pipe (water, gas);When choosing the DGJ self fixing metal hose joint, please pay attention to the specification and size of the connecting pipe hose.

Q:Method for inserting glass tube into rubber tube when assembling instrument

The sleeve method of different outer diameter glass tube should be determined according to the size of the outer diameter. If the outer diameter of the two tubes is not big, then the rubber tube with the same inner diameter can be connected. When connecting to the rubber sleeve in the larger outer diameter glass tube, the specific method, with a diameter from one end of the rubber tube of the same stick (such as chopsticks) inserted into the connection end to the rubber tube, rubber tube set in reverse, then the larger outer diameter glass tube against the wooden stick. The rubber hose forward turning sleeve on a glass tube, stick out.

Q:The engine cylinder head cover behind the drop rubber tube what reason (Xichai 490 engine) (note the valve chamber cover tube)

The valve chamber of the engine cylinder head cover counterclockwise with 8~10 open wrench counterclockwise unscrew rocker screw. Place the piston at the top dead center, turn the rocker head wire clockwise until the hand can not be moved, then back half a circle, then lock the nut.

Q:The difference between the rubber pipe and PE pipe

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, electric.

Q:The difference between hose and rubber tube

Latex tube is characterized by good elasticity, general tensile range of 6-9 times its own, back to stretch 100%. The rubber tube has the characteristics of oil resistance, acid and alkali resistance, heat resistance and pressure resistance, and attracts rubber pipes. It is mainly used in industry, mine, civil transportation and suction of liquids, gases and so on.Latex tube is generally used in hospitals, equipment factories, power plants, scientific research laboratories and other fields, but also related to bungee jumping, trampoline and other places of entertainment. Rubber tubes are mainly used in industry and agriculture. Latex tube is not resistant to oxidation and corrosion, and rubber tube has one of the characteristics, so its scope of application is more extensive.

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:Acid burette and how to distinguish the basic buret

Alkali: rubber tubes. Acids: glass tubes (remember: NaOH and glass reactions. So rubber)
