Device for branch joint with an electric drive ST-UV-E

Purpose

■ branch joint into the existing process pipeline under product pressure
(transported medium) with preservation of tightness by tie-in

■ the tie-in process is carried out by cutting of a hole through
pre-welded to the pipe branch pipe with fl ange and a fl ange-mounted
gate valve (ball valve)

■ branch joint is carried out by an electric drive

Purpose area

■ repair and installation of pipelines for various purposes

■ the device is used in the fi eld environment, on industrial objects.
Climatic category NF1

■ ensures that there is no need for preliminary pipeline shutdown

Working environment in the pipeline

■ oil

■ gas

■ steam

■ water
