Q:Could you tell me the maximum pressure that the hose can bear?
Production process with pressure hose hose to withstand the enhancement layer material has a great relationship with the enhancement layer, the enhancement layer of the same level, generally the larger diameter bearing capacity is small, the enhancement layer is cloth or steel wire line and the enhancement layer is also different. Select the hose you want according to your requirements. The hose pressure is 4 times the normal pressure
Q:What do you mean by "DN" on hydraulic hose?
Hydraulic hose is mainly composed of liquid synthetic rubber, inner rubber layer, middle rubber layer, multi-layer reinforced layer and weather resistant synthetic rubber outer layer. The utility model is mainly used for hydraulic support and oil field development of a mine, and is suitable for engineering, construction, hoisting, transportation and automation hydraulic system to transport medium and water base fluid with certain pressure and temperature.
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 does the letter of the high-pressure tubing connector mean?
The high-pressure tubing is part of high-pressure oil pipe, tubing requirements needs to bear certain pressure and fatigue strength, ensure the sealing requirements of pipeline, mainly in high pressure injection diesel engine high pressure oil pipe for car, high pressure injection and direct injection gasoline engine, oil required under the engine running in the process.
Q:How to identify the quality of rubber pipes for sewage treatment?
A tubular rubber product used to transport gases, liquids, slurries, or granular material. It is composed of inner and outer rubber layer and skeleton layer. The material of skeleton layer can be made of cotton fiber, various synthetic fiber, carbon fiber or asbestos, steel wire and so on.
Q:What's the cause of a default like a general rubber product?
Rubber aging is a common problem of rubber products, and aging is mainly due to internal structure or component is easy to aging due to weakness, such as unsaturated double bond, branched, carbonyl, hydroxyl and so on; at the end, the main external or environmental factors are sunlight, oxygen, ozone, heat, water and mechanical stress force, high energy radiation, electricity, industrial gas, water, salt fog, fungi, bacteria, insects etc..
Q:Aging of natural gas pipeline
1, when in use, should always pay attention to the color of the fire. Orange flames indicate incomplete combustion of gas, and in this case carbon monoxide is released. The fire can be adjusted by adjusting the air door at the bottom of the stove, and the flame is blue.2, soup or water, containers should not be overfilled, nor unattended, so as to avoid the fire was spilled soup, water and water leakage.3, in a stew or soup, some people love the flame was very small, this can easily lead to leakage or incomplete combustion. Therefore, in the use of gas stoves, the fire can not be too small.Between the 4, and gas appliance hose inlet connector to connect closely, preferably with a pipe clip.5, in the same room, strictly prohibit the simultaneous use of two kinds of fire sources.6, the family is best equipped with dry powder fire extinguishers, so as to be prepared.
Q:How do I get the hose for the gas cooker?
Stainless steel bellows, stainless steel bellows, with a service life of ten years. The outside of the tube is covered with a layer of yellow plastic. All the inside are made of stainless steel. The ends of the pipe are connected with the mouth. There is also a black rubber piece, which is connected with the valve. After the tightening, the rubber sheet will expand and prevent the depression. Some live in a building or a cottage residents, plastic hose home is often a mouse or other insect bite, the use of stainless steel tube after it will not happen.
Q:Plastic metal hose connector model specification, who knows?
Package type plastic hose is many, the most common is the DPJ thread joint, DPN joint, DKJ card connector, DGJ self fixed joints, Glenn joints, fittings
Q:High pressure hose K type joints KJR32 and KJR31.5D what is the difference between ah, please give us a answer,
K type joint has the distinction between national standard and German standard. In general, 32 and 38 tubes are used more often. The joints used on 32 of the tubes are KJR32 and KJR31.5D. 38. The joints used on the tubes are KJR38 and KJR B40
