Victaulic AGS Rigid Coupling For Stainless Steel Pipe Style W89

Kami stok dan jual Victaulic AGS Rigid Coupling For Stainless Steel Pipe Style W89 Jakarta Indonesia.

This rigid coupling greatly reduces linear and angular movement at valve connections and other points where rigidity is required. The Style W89 is suitable for use where the corrosion resistant properties of stainless steel are not required for the external environment. Working pressures shown are for Schedule 10S stainless steel pipe AGS roll grooved in accordance with Victaulic specifications. AGS Rigid Coupling with AGS Vic-Ring STYLE W89 - Rigid Coupling Style W89 AGS ( Advanced Groove Systems) couplings for AGS Vic-Ring systems are designed with ductile iron housings for higher pressure piping systems. The wedge-shaped coupling housing keys fully engage the patented AGS grooves on the ring to provide a rigid joint. To achieve this rigidity, it is necessary to torque the nuts to the values shown in the torque requirements table on page 4. Style W89 AGS is used on valve connections and other joints where rigidity is required. The couplings are galvanized and provided with plated bolts and nuts and FlushSeal gaskets for a variety of services. Please specify gasket grade when ordering. Refer to publication 05.01 for gasket services ratings. Style W89 AGS couplings on Vic-Rings are designed for pressures up to 700 psi/ 4850 kPa on standard wall carbon steel or heavier pipe for 12 – 14" / 300 – 350 mm systems, and up to 580 psi/ 4000 kPa for 16 – 22" / 400 – 550 mm piping systems and fit pipe that meet API 5L pipe end dimensions. AGS Vic-Rings can be manufactured to meet most pipe specifications. Contact Victaulic for details. NOTE: Couplings used for AGS Vic-Ring systems are one size larger than the pipe.
