How Are Stainless Steel Pipe Fittings Connected?

There are many ways to connect stainless steel pipe fittings. The mainstream ones include clamping connection, ring connection, flange connection, welding connection, and tapered thread connection. Each has its pros and cons, and you need to find a suitable method based on the actual situation.

Clamping connection

The connection principle of this method is to use hydraulic pliers to clamp the stainless steel pipe fittings on the pipe, and at the same time use an O-ring to stop the water, so as to achieve the connection effect. Although this method is simple to operate, the pipe wall is very thin, the connection strength is as low as about one-third of the pipe body, and the pipe cannot be disassembled. If the burrs and burrs on the port of the stainless steel pipe are not cleaned, it is easy to damage the rubber ring and cause water leakage in the future.

Ring pressure connection

The principle of ring pressure connection is to use hydraulic pliers to clamp the stainless steel pipe fittings on the pipe, and use a wide rubber sealing ring to stop the water to achieve a good connection effect. Because this method has one more indentation than the clamping type, the strength of the connection is slightly stronger than the clamping type. In addition, because the indentation is circular, the pipe is easy to rotate, which will affect the overall sealing effect.

How Are Stainless Steel Pipe Fittings Connected

Flange connection

The principle of flange connection method is to tighten the bolts, use flange plates to connect the two pieces, and then use flat sealing plates to seal them to achieve the corresponding connection effect. The advantages are high connection strength, stable quality, and easy installation and disassembly. The disadvantage is that the cost of the flange is relatively high.

Solder connection

The principle of this connection is that the two connecting pieces are directly welded through a hot melt process to achieve the connection. Its advantage is high connection strength, but its disadvantage is that it is difficult to meet the welding gas protection standards for on-site welding joints. The welds are easy to rust, which will reduce the service life of the pipeline. The installation quality depends largely on the technical level of the welder, so Quality stability is not high.

Threaded connection

The principle of this connection is to directly tighten the stainless steel pipe fittings. Its advantages are easy disassembly, convenient and simple installation, reliable and stable quality, thin pipe wall and low cost. In addition, if the external threaded interface is wrapped with PTFE material tape, it requires force. If liquid material tape is used, it can basically ensure that the interface does not leak for a long time.
