UNIVERSAL joints made by ARMAS are universal joints for pipe failures whichconnect pipes made from either same or different material.
These joints are used for repairs of pipeline failures when a pipe rupture is of such a length that cutting off pipe and inserting a new piece of pipe is necessary.
UNIVERSAL joints are divided into two generations based on their constructive solution: first (I) and second (II).
Second generation UNIVERSAL joints are upgraded version of first generation UNIVERSAL joints, with all the positive features and advantages of the first generation joints, but with larger installation lengths and much wider range of diameter which is covered by one joint, i.e. they are completely universal.
Because of the stated, UNIVERSAL II generation joints are being dominantly used in the nominal diameter range of DN50 to DN300 due to the fact that they are completely universal and cover all pipe types of the same nominal diameter, even the non-calibrated diameter of asbestos-cement pipes, type D, which is a rarity.
For the nominal diameter range of DN350 upwards UNIVERSAL I generation joints are still being mostly used because they have a lower mass due to their shorter installation lengths, which is an advantage in terms of cost and easy handling during installation, especially because with the increase in nominal pipe diameter there is less importance in universality of the joint (although these joints still cover a wide range of outer pipe dimensions for each nominal diameter).
Additional advantage of using UNIVERSAL I joints is that in cases of very limited installation space damages on pipelines can be resolved by using just one joint in such way that only a small part of the pipe is being cut off, in sufficient size to enable inserting parts of the joints through (one half of the joint goes on each side of the opening) and then, by simply connecting inserted parts, the installation and repair is complete.
