The importance of well-crafted fittings
May 26th, 2019
As an established supplier of tube fittings in the Australian and New Zealand markets for over 27 years now, Ultibend has become known as the benchmark for quality tube fittings. However, not all fittings in the market measure up to that level. There can be several faults that significantly increase the difficulty and cost of install. We thought we should point out some of the key differences for you to look out for.
Wall Thickness
AS1528.3, +/- 10% = 0.16mm on 1.6mm tube
How does this affect installing?
A consistent wall thickness makes welding a lot easier as weld penetration remains the same, matchup is more straight forward and install times are reduced. Also, orbital welders will work more efficiently when using bends with consistent wall thickness.
Bend Angle

How does this affect installing?
Under and overbent fittings can cause the pipeline to wander off square when welded in. If working to a pre-drawn design, the actual fittings may not match the drawings. This can lead to quality assurance issues, increased project costs, and time delays.

Cut Face Squareness
Cut face squareness can be measured in up to three different ways
Cut square face to face
Cut Square off plane
Cut square face to straight
I can honestly say I have never had any problems when welding Ultibends and have had many tested on-site, with excellent results.
