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?: Br2 bromine gasBr2 bromine element at room temperature is dark brown liquid, soluble in water, 100g water can dissolve about 3G bromine. Highly volatile, toxic, steam strongly stimulate the eyes, mucous membranes and so on. The water solution is called bromine.

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: My company does high-quality rubber tube, all of the core method, and why use EPDM to do the inner tube, it is difficult to take off the core, please point out! What's the reason?: The core needs to be removed, and if it is too long, the mandrel can be divided into two sections and separated from the 2 sides

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: Which is safer for stainless steel bellows and rubber tubes for gas pipelines?: The stainless steel bellows and the quick fitting joint connection way mostly uses the end face seal, may avoid the thread seal to be lax strictly the leakage, compared with the traditional installment, its leakage probability will reduce greatly.

Q: Petroleum gas has a corrosive effect on ordinary rubber pipes and is easy to cause air leakage. So, what kind of hose must be used?: In order to remind people of the leakage of liquefied petroleum gas in a timely manner, the processing plant often mixes a small amount of foul odor mercaptan or thioether compounds into liquefied petroleum gas, which is the source of special odor.

Q: What kind of material is the rubber tube with acid, alkali and high temperature resistance made of?: Silicon rubber tube, also known as silicon rubber tube, ordinary silicon hose can withstand temperature of 250 degrees, high temperature resistant material of silicon hose can reach about 350 degrees. And its tear resistance and elasticity are very good. It is widely used in high temperature environment. If you don't understand, you can ask me

Q: What is the high and low pressure circuit of diesel engine?: Low pressure means the fuel tank to the big pump (directly driven by the engine). High pressure means the large pump to the injector

Q: Do you need a hose connection to connect the ventilation pipe to the exhaust fan? Under what circumstances? Under what circumstances?: The exhaust fan running noise and vibration is relatively large, the wind pipe made of sheet iron, the thin wall affected by the fan vibration will produce two times the noise, so the general air pipe to both sides of fan and soft joints, if no one in the floor or the condition of small diameter pipeline can not be added.
