Non-adjustable pipe elbows

About non-adjustable pipe elbows

A fixed elbow joins two Ø42.4 mm tube sections at a defined angle – 90° or 135°. It has no moving parts, so it does not work loose over time.

It is also the cleaner choice visually: the transition is even, with no visible adjustment point.

The Strofix range covers weld-on elbows, and flush, round and rounded versions, in satin, polished and raw.

AISI 316 is available for some versions – for coastal sites and pool surrounds.

The choice depends on angle, shape, mounting method and whether the elbow sits at hand height.

How to choose a fixed pipe elbow

1. Angle: 90° or 135°

90° suits rectangular terraces and balconies.

135° is for chamfered corners and polygonal plans. Two 135° elbows together give the same turn as one 90°, but with a chamfered corner – a common terrace solution.

2. Shape: flush, round or rounded

The flush elbow makes a sharp transition and is the least noticeable.

Round and rounded elbows make a flowing transition. If the elbow is on a handrail at hand height, choose the rounded one – a sharp transition is felt every time.

3. Glued-in or weld-on

A glued-in flush elbow goes into the tube ends and is fixed with adhesive – no welding and no finish to restore on site.

The weld-on elbow is welded between the tube ends and becomes almost invisible once the seam is dressed. It is also supplied raw, since the finish has to be restored anyway.

4. When fixed is the wrong choice

On stairs and irregular plans. There the real angle differs from the nominal one, and a fixed elbow would force the tube together under stress.

Forced assembly leaves permanent stress in welds and fixings. In that case choose the adjustable version.
