Product description

The socket weld flange has a bored recess that accepts the pipe, which is then fillet-welded on the outside. No beveling or precise alignment is required, making it ideal for small-bore high-pressure lines such as instrument tubing, steam tracing, hydraulic systems and small-diameter process piping.

Key features

No beveling or alignment needed - the fastest option for small-bore piping
The socket shoulder keeps the bore flush for low flow resistance
First choice for high-pressure lines DN50 and below
Low welding distortion, ideal for instrument and precision lines

SW Class 150 – 2500
