Loader brake tubing&jointt function: connect the Air Booster Pump, Air Brake Valve , Oil-water Separation Combined Valve For Loader, Loader Brake Clamp, etc., different models, joint form, size is different
The difference between type C and type H hydraulic tubing joint
First, the opening degree of type C and type H hydraulic tubing joint is different
1, hydraulic tubing joint C type: hydraulic tubing joint C type is 60 degrees bell mouth;
2, hydraulic tubing joint H type: hydraulic tubing joint H type is 24 degrees cone.
Two, the use of hydraulic tubing joint C type and H type is different
1. Hydraulic tubing joint TYPE C: hydraulic tubing joint type C is used to connect with flaring type pipe joint;
2. Hydraulic tubing joint H type: hydraulic tubing joint H type is used for o-ring sealing joint.
Type of hydraulic pipe joint
Welding type pipe joint
Use nozzles to weld pipes. O-ring end seal is used between the joint body and the nozzle. Simple structure, easy to manufacture, good sealing, the accuracy of the pipe size is not high. High quality welding requirements, inconvenient assembly and disassembly. Working pressure up to 31.5mpa, working temperature -25 ~ 80℃, suitable for oil as the medium of pipeline system.
Two, card sleeve type pipe joint
Using the clamping sleeve deformation stuck pipe and seal, advanced structure, good performance, light weight, small volume, easy to use, widely used in hydraulic system. The working pressure can be up to 31.5mpa, requiring high precision of pipe size, cold-drawn steel pipe is required. The accuracy of the sleeve is also high. Suitable for oil, gas and general corrosive medium pipeline system.
Three, flaring type pipe joint
Use the pipe end flaring for sealing, no other seals. Simple structure, suitable for connecting thin-wall pipe fittings. Also suitable for oil, gas medium for low pressure pipeline system.
Type C has a 60 degree bell mouth and Type H has a 24 degree cone.
1. Hydraulic oil is the hydraulic medium used by the hydraulic system using liquid pressure. It plays the role of energy transfer, anti-wear, system lubrication, corrosion prevention, rust prevention and cooling in the hydraulic system.
2, for the hydraulic oil, first of all should satisfy hydraulic equipment in working temperature and the temperature of the liquid viscosity requirements, as a result of the lubricating oil viscosity changes directly related to the hydraulic action, transmission efficiency and transmission accuracy, also requires oil viscosity-temperature properties and shear stability should meet the diverse needs of different USES the proposed.
3, there are many kinds of hydraulic oil, classification methods are different, for a long time, used to classify by use, but also according to oil type, chemical composition or flammability classification. These classification methods only reflect the income of oil products, but they are not systematic, and it is difficult to understand the relationship and development of oil products.

Recently, it was learned from Anshan Iron and Steel Group Co., Ltd. that in early July, Angang signed a production contract with the user for the transportation of liquefied ethylene gas (LEG) marine 5% nickel steel plate, marking a substantial step for Anshan Steel to open up the LEG marine 5% nickel steel plate market. .
In recent years, China is accelerating the construction of large-scale ethylene projects of 8-10 million tons. The demand for 5% nickel steel for low-temperature materials required for production, processing, storage, transportation and transportation of ethylene has increased year by year. Due to the difficulty of production technology, there are no manufacturers in China that can produce this kind of steel, and all rely on imports. Therefore, the research and development of 5% nickel steel is of great significance to promote the technological progress of the metallurgical industry and promote the development of the energy industry.
At the beginning of 2008, Anshan Iron and Steel Co., Ltd. began to develop 5% nickel steel based on the successful development of 9% nickel steel. After two years of laboratory research, Angang has mastered the appropriate chemical composition range, production process and its structural changes of the steel, and formed a technical scheme for industrial trial production. At the beginning of the year, Anshan Iron and Steel successfully carried out the industrial trial production of 5% nickel steel "converter + continuous casting", and rolled out 6-60mm steel plates of different thickness specifications. After testing, the performance of the steel plate reached the level of similar foreign products, filling the domestic gap. For marine steel, it is only through the classification society that it can enter the shipboard production market. The 5% nickel steel of 6-60mm thickness specification produced by Anshan Iron and Steel Co., Ltd. has passed the certification of the classification societies of Norway, Britain, China and Germany, which indicates that the production of 5% nickel in Anshan Iron and Steel has reached the international advanced level.
Anshan Steel successfully developed LEG marine special steel plate
