LONG EXTRA+ joints are used for connecting one or two secondary pipelines on the primary pipeline, while primary pipeline can be already in exploitation or in the process of making like the secondary pipeline.
Depending on the number of secondary pipelines, and their position in relation to the primary pipeline, there are following joints:
– LONG EXTRA-P
– LONG EXTRA-P45
– LONG EXTRA-P/P
– LONG EXTRA-P/P45
– LONG EXTRA-P45/P45
LONG EXTRA+ joints replace certain fittings and E-pieces in installation, while the installation of joint is made without pipe cutting and, under specific conditions, without consumers being cut-off.
Basic advantages of using LONG EXTRA+ joints are represented in the fact that during the installation of secondary pipelines, pipe of the primary pipeline is not being cut, which makes forming the pipe connection, i.e. installation of joint, simple, fast and easy.
With the stated way of installation, every possibility for water power stroke is eliminated (because there is no pipe cutting during the installation of the joint, so there is no opportunity for air to enter the pipe and create conditions for water power stroke), and advantage of installation without turning off the water is that after the installation and commissioning of the pipeline there is no blurred water, nor are possible consumers cut-off during the installation.
LONG EXTRA+ joints are part of ARMAS SYSTEM.
