Hydraulic pipe joint can be divided into hydraulic hose, high-pressure ball valve, quick joint, jacketed pipe joint, welded pipe joint, high-pressure hose, transition pipe joint, jacketed pipe joint, three-way pipe joint, etc. Hydraulic tubing is a special product, the key points of its promotion need to focus on the hydraulic tubing joint specification standards, hydraulic tubing joint specification standards are often the focus of users. Because the impact force of the hydraulic oil pipe suddenly burst is very big, the special joint can not be replaced with ordinary, because the hydraulic pressure can bear a lot of pressure, ordinary up to 0.5 air pressure is already fast. The following xiaobian will simply introduce you to the hydraulic tubing joint specifications and standards:
First, flaring type
1. Flaring end straight pipe connector (GB/T 5625-2008);
2. Flared taper thread straight pipe joint (GB/T 5626-2008);
3. Flared taper thread long pipe joint (GB/T 5627-2008);
4. Flaring type straight pipe connector (GB/T 5628-2008);
5. Flared taper thread bending pipe joint (GB/T 5629-2008);
6. Flaring type bending pipe joint (GB/T 5630-2008);
