PIPE CONNECTIONS AND ACCESSORIES CONNECT PIPES BETTER, FASTER AND SAFER This stainless steel coupling offers numerous advantages in comparison to similar connecting elements. This is due to the fact that this coupling contains two special components that make it so unique. A patented seal prevents leaks and a specially shaped anchoring ring ensures a reliable and permanent connection. Thanks to the wide variety of types, it can be used as a connecting element between pipes made from diverse materials and with different external diameters.

TECHNICAL INFORMATION AND OVERVIEW PE 80 / PE 100 Pressure limitation The pressure limitation of PE pipes and fittings is expressed in SDR-grade (SDR = standard dimension ratio = ratio outside pipe diameter / pipe wall thickness). Decisive for this are the currently revised standards and proposed standards (prEN 1555, DIN 8074 [E] and DIN 8075 [E] considering the new design factor C (Calculation coefficient for PE-HD components = 1.25). Depending on the used PE-HD material the following pressure levels can result: Technical Documentation All information and contents are subject to change without...

The installation time includes: • Marking the half coupling width non both pipe ends • Correct alignment of the coupling • Tightening the bolts with a torque wrench Technical Documentation All information and contents are subject to change without liability, errors and changes reserved.

MISALIGNMENT PEWOCOUPLING pipe connections compensate angular offsets up to 2° (4°) in every direction. Easy installation. That does away with the need for complex alignment of the pipes. It is also possible to use pipes with an angular offset as a connecting element for dynamic angular offset movements, after installation, during operation of the pipe. Example: Ground subsidence Universal joint via 2 couplings Note: Pipe end spacing Cmax must always be complied with. AXIAL OFFSET PEWOCOUPLING pipe connections allow an axial offset. However, we recommend avoiding the parallel offset or modifying...

If line guides are a sufficient distance from the pipe joint, so that the pipe ends can be operated manually with a small force effort (approx. 500 N), the remaining offset will inevitably be kept small after tightening the coupling. In such applications, a slight inclination of the coupling on the pipe joint is to be expected. SUBSEQUENT INSTALLATION OF PIPE SECTIONS, MOULDED PARTS AND FITTINGS The simple transfer to pipes and the wide tolerance field of the pipe coupling make this an ideal component for subsequent installation of pipe sections, moulded parts or fittings in case of line modifications...

AXIAL MOVEMENTS / LENGTH CHANGES Temperature load changes on the pipeline system generate axial movements. Or tensile and compressive stresses, which have to be compensated by appropriate measures. • Compensates length changes in the pipes at temperature fluctuations • No abrasion of the sealing collar (milling in the seal) • Compensation space for the volume change in the sealing materials • Tension-free pipeline without additional elements (see above) PEWOCOUPLING pipe connections of type series PEWOFLEX and PEWOREP are able to compensate axial movements by straight pipe sections, depending...
