What are the specifications and standards of hydraulic oil pipe joints?

After years of development, the hydraulic tubing in China has become very mature. Hydraulic oil pipes are mainly used for non corrosive or corrosive media such as oil, water and gas. With the increasing demand for such products in many fields, the publicity and promotion of such products are also the focus of businesses. The hydraulic pipe joint is a component in the hydraulic system that connects the high pressure oil pipe and the high pressure oil pipe.

Hydraulic couplings can also be divided into hydraulic hoses, high-pressure ball valves, quick couplings, ferrule couplings, welded couplings, high-pressure hoses, transition couplings, ferrule couplings, three-way couplings, etc. Hydraulic tubing is a special product. The key points to be paid attention to when promoting hydraulic tubing are the specifications and standards of hydraulic tubing joints. The specifications and standards of hydraulic tubing joints are often the focus of users’ attention. Because the impact force of hydraulic oil pipe burst suddenly is very large, it is not allowed to replace special joints with ordinary ones, because hydraulic ones can withstand a lot of pressure, and ordinary ones with a maximum of 0.5 air pressure are almost exhausted. The following is a brief introduction to the specifications and standards of hydraulic oil pipe joints:

1、 Flared type

1. Flared end straight pipe joint (GB/T 5625-2008);

2. Flared type taper thread straight pipe joint (GB/T 5626-2008);

3. Flared type taper thread long pipe joint (GB/T 5627-2008);

4. Flared type straight pipe joint (GB/T 5628-2008);

5. Flared type taper thread elbow (GB/T 5629-2008);

6. Flared elbow fittings (GB/T 5630-2008);

2、 Ferrule type

GB3737.1-83 Ferrule type straight pipe joint;

GB3737.2-83 Ferrule type straight connector body;

GB3733.1-83 Ferrule type end straight pipe joint;

GB3733.2-83 Ferrule type straight pipe connector;

GB3735.1-83 Ferrule end straight long pipe joint;

GB3735.2-83 Ferrule type straight long pipe connector;

GB3734.1-83 Ferrule type taper thread straight pipe joint;

GB3734.2-83 Ferrule type taper thread straight connector body;

GB3754.1-83 Ferrule type end butt joint straight pipe joint;

GB3754.2-83 ferrule end butt joint straight connector body;

GB3755.1-83 Ferrule type taper thread butt joint straight pipe joint;

GB3755.2-83 Ferrule type taper thread butt straight connector body;

JB/ZQ4401-97 Ferrule type taper pipe thread straight pipe joint;

JB/ZQ4402-97 Ferrule type taper pipe thread long pipe joint;

JB/ZQ4406-97 Ferrule type taper pipe thread butt joint straight pipe joint;

The above are the specifications and standards of the common hydraulic oil pipe interface, in addition to others. With the rapid development of the hydraulic pipe market in China, the application and R&D of related core production technologies will become the focus of the industry enterprises. Understanding the R&D trend, process equipment, technology application and trend of core technologies for hydraulic pipe production at home and abroad is crucial for enterprises to improve product technical specifications and market competitiveness. This not only deeply affects the future of hydraulic tubing, but also has a profound impact on the development of the entire hydraulic tubing industry in China. China is still a developing country, and there is still a certain gap between many technologies and developed countries. How to improve the competitiveness of our own products requires not only the efforts of several people, but also the wisdom of several generations.
