Q: What do you mean by "DN" on hydraulic hose?: DN stands for nominal diameter. The standard diameter after standardization, the midpoint between the inner diameter and the outer diameter, in units mm.

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: What is a rubber core pulling method?: Hose core pulling for broken line and curve type pore channels, in addition to leaving the grouting hole and exhaust hole should also set the urinary bleeding hole, hole curve (line) to stay in the top hole, with the method of grouting hole.

Q: What is a hose valve?: [hose valve features]1, abrasion resistance, corrosion resistance, frost resistance, sealing performance, and only the replacement of rubber sets, that is, as good as new, the valve body can be used permanently, life expectancy is 4-6 times the ordinary valve.2, sealing special good: both ends of the hose with rubber flange, when the valve and pipe connection, no need to seal the gasket, thereby eliminating the running, risk, drip, leakage and other undesirable phenomena.3, good cold resistant performance: the fluid flow in the flexible hose, thereby eliminating fluid crystallization caused by evil shell cracking.4, scientific and reasonable structure, simple operation and flexible, convenient maintenance, maintenance, as long as the replacement hose, valve and other institutions can be used for a long time, thereby improving the service life of the valve, greatly saves the production cost of the user, in line with value engineering.5, the valve structure is simple, is the only non leakage valve, capable of a variety of medium concentrations of acid and any concentration of alkali salt solution, can transport pulp, dry and wet powder, as well as crystal object medium.6, different media can choose different rubber formula hose, to meet the needs of different users.

Q: Hose connector JB1885-77 what is the standard?: GB A flat joint core series hose assembly standard.

Q: What are the main differences between stainless steel flexible joint and rubber soft joint?: Stainless steel soft joint and rubber flexible joint are used as flexible components to absorb vibration and noise.

Q: What are the pipes in the air conditioner?: General automotive air conditioning work principle: compressor exhaust, condenser, liquid storage dryer, expansion valve, evaporator, compressor suctionEach of the arrows (except the expansion valve to the evaporator) represents an air conditioning line. Some of them are rubber tubes and some are made of metal tubes.

Q: Is the installation of submersible pumps mandatory for the installation of flexible rubber joints?: Deep well submersible pump must be equipped with steel pipe, water pipe.Submersible submersible pump, such as submersible sewage pump, according to the use of requirements, consider whether to install the flange connection form, Song River rubber soft joint, so it is not necessary.

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.
