Introduction, advantages and disadvantages of hydraulic pipeline standards

I have learned the relevant knowledge of hydraulic hoses introduced by Bian Xiao in the last issue, and I believe everyone has a certain understanding of building materials knowledge in this area. So today, Bian Xiao will introduce a building material that is more widely used than hydraulic hoses, that is, hydraulic pipes. With the rapid development of hydraulic pipe market, hydraulic pipe has become a research hotspot of enterprises in the industry. Today, let's learn more about its related standards, advantages and disadvantages through an article!

What is a hydraulic pipe?

Hydraulic pipe is called hydraulic pipe because it is a kind of pipe used to transmit hydraulic pressure, and it is divided into hard pipe and flexible pipe, in which the hard pipe is mainly seamless steel pipe, while the flexible pipe is made of layered steel wire mesh and rubber. Flexible pipes are often used in parts that need to be bent and changed in the working environment, while rigid pipes have strict standards. We can choose the diameters of different hard pipes and hoses according to the flow rate of the conveying medium, and we can also choose the pressure grade of the pipeline according to the pressure of the hydraulic pipeline.

Hydraulic pipeline standard

Standard of hydraulic rigid pipe: Seamless steel pipe for fluid shall conform to the national standard GB8 163-99, and high-pressure seamless steel pipe for fertilizer equipment shall adopt the standard GB6479- 1999. YB69 1-70 standard should be adopted for the special hydraulic pipe for petroleum drill collars. As for hydraulic hoses, they are mainly divided into three types of implementation standards. The first type is d in, SAE, ISO, GB/T standards that are often used in trade, and the second type is DIN? Hmm? 853、SAE？ J5 17、GB/T？ 3683-20 1 1, ISO 1436 and other types. Finally, the hydraulic hose is wrapped around DIN? Hmm? 856、SAE？ J5 17 and other types.

Advantages and disadvantages of hydraulic pipeline

Advantages of hydraulic pipeline

The biggest advantage of hydraulic pipe is that it is more flexible and convenient than electric rotation and mechanical rotation. It is not only light in weight, but also very small in size and very convenient to operate. Secondly, it can automatically realize overload protection, stepless speed regulation in a wide range, and the reaction speed is also considerable.

Shortcomings of hydraulic pipeline

Because the hydraulic pipe has large fluid flow resistance and leakage when it is used, the efficiency can be said to be very low. We must handle it properly manually to ensure that the leak will not pollute the site. If not handled properly, it may cause fire or other accidents. Secondly, the components of hydraulic pipes are more expensive to manufacture than ordinary components because of their higher accuracy.

The above is the standard knowledge about hydraulic pipeline introduced by Bian Xiao. When buying hydraulic pipes, the safety of the workplace must be fully considered to prevent accidents.
