PRESSING CONNECTIONS

Today there is a set of ways to connect or repair the pipeline: welding, flange connection, a threaded connection or mechanical connection by means of couplings.

One of leaders in mechanical connection (pic. 1) of pipelines is the Straub Werke AG firm (Switzerland Vangs). In the field of pipe connections the firm works more than 40 years and thanks to continuous work on improvement of the production the Straub Werke AG firm possesses the fullest production program of products for mechanical connection of pipes and shaped products and holds conventionally a leading position in the area. Pipe connections of Straub find applications in such areas of the industry as chemical, oil and gas, power, water supply, high-rise / tunneling, shipbuilding, mechanical engineering. In practice installation of Straub couplings happens very quickly, simply and reliably: the compact element needs to be aligned in a zone of a joint of pipes and to twirl bolts. All types of Straub couplings can be divided into two main types conditionally: Grip (rigid axial coupling, is carried out by a special anchor ring) and Flex (the flexible axial coupling demanding additional points of fixing on the pipeline). On the basis of these two types there are eight types of couplings for various applications and repair collars. Heat supply – a new line of couplings and clamps STRAUB through the use of the seal of EPDM, capable of withstanding the peak load up to 135°.
