Connecting principle: insert the pipe into the pipe fitting, then extend the edge of the pipe fitting, a circle of argon arc welding connection, so that the pipe fitting self-melting into one;

Advantages and disadvantages :1. Reliable connection, is a reliable connection of all the connection modes, almost no maintenance; 2. 2. Low cost, compared with other connection methods, the cost of this kind of products is lower; 3. Complete specifications, this kind of pipe fittings complete specifications.

Viega profi-press

Connection principle: Use radial contraction external force (hydraulic clamp) to clamp the pipe fitting on the pipe, and through the O-ring sealing water, to achieve the connection effect.

Advantages and disadvantages: 1. Thin-walled pipe and pipe fitting, saving materials 2. Low connection strength (the connection strength of the interface is less than 1/3 of the strength of the pipe body)3. Pipe can not be removed 4 pipe port burr, flanged clean will damage the rubber ring, become the hidden danger of water leakage in the future.

Annulus pressure type

Connection principle: The radial contraction external force (hydraulic clamp) is used to clamp the pipe fitting on the pipe, and the water is sealed by the wide band rubber seal ring to achieve the connection effect.

Advantages and disadvantages: 1. Thin-walled pipe and pipe fitting can be realized and materials can be saved. 2. Due to the addition of a pressure pit, the connection strength is slightly better than that of the clamping type (the interface strength is still less than 1/2 of the pipe body strength). 4. Because the pressure pit is circular, the pipe is easy to rotate, affecting the sealing effect 5. The burr of the pipe end, the flange is not clean will damage the apron, become the hidden danger of water leakage in the future.
