The classification of metal joints is mainly based on their use, shape and connection mode. The following are some common categories of metal joints:
1. External threaded joints: this joint is mainly used for the local junction box and hose and other parts of the connection. It processes the threads outside the joint and connects with the threads inside the supporting parts, so as to realize the purpose of fastening and connection.
2. Internal threaded joint: corresponding to the external threaded joint, the internal threaded joint is threaded internally to connect with the external threaded components, such as the buckle connection between the cable pipe and hose.
3. Card sleeve joint: this kind of joint is mainly used for the connection of metal hose and stainless steel metal hose. It insta sleeve at the end of the steel pipe to achieve fast and firm connection, with the characteristics of convenient installation.
4. Plug connector: When the embedded pipe is dense and gap, the plug connector is particularly practical. It is mainly used to insert the inner diameter of the stainless steel pipe to realize the connection with other parts, which also has the advantages of convenient installation.
5. The diameter joint: in the case of the diameter of stainless steel pipe and metal hose is inconsistent, the diameter joint can play an important role. It can realize the size of the pipe diameter, to meet the connection needs of different calibers.
6. Welded joints: including butt joint, corner joint, welding joint and t-joint and other forms. These joints are connected together with two or more metal materials by welding, which has the characteristics of strong connection and good sealing, but the welding technical requirements are relatively high. In addition, there are other special types of metal joints, such as dkj clamp metal hose joints, dgj self-adjusting metal hose joints, 90-degree bending joints, y-joints, t-joints and stainless steel joints, which play their respective roles under different application scenarios and connection requirements. In general, the classification of metal joints is diverse, which joint to choose depends on the specific connection requirements, working conditions, and use environment.
