Buttweld Fittings Elbows (90,45 & L80 )

Buttweld Fittings Elbows (90,45 & L80 )

We manufacture of butt weld pipe fittings to meet diverse material specification. The function of a elbow is to change direction or flow in a piping system. By default, there are 5 opportunities, the 45°, 90° and 180° elbows, all three in the “long radius” version, and in addition the 90° and 180° elbows both in the “short radius” version.
