Plidco Weld + Ends
Standard PLIDCO® Weld+Ends® Couplings have a single row of clamping screws at each end. Where excessive end-pull loads are involved and welding is not feasible, additional rows of clamping screws can be provided or a PLIDCO ® Clamp+Ring may be used. Special installation instructions are necessary for thin wall applications. Contact PLIDCO® for details.
Available in standard sizes 1-1/2″ through 48″.
Special sizes, diameters, pressures and lengths available upon request.
Buna-N packing is standard.
Viton, Silicone and other packings available upon request.
Standard body materials:

– Marine epoxy paint for corrosion protection
– NACE MR0175/IS0 15156 compliant material
Pipe not anchored: A joint in which the pipe ends could move when subjected to internal or external forces, such as internal pressure, temperature expansion and contraction, underwater currents, ground movement or any combination thereof. The assigned Plidco® Weld+Ends® Pipe Not Anchored rating (as listed in chart) considers only static force created by the internal pressure. It does not consider any additional external forces such as temperature expansion and contraction, underwater currents, ground movement or any combination thereof. These additional external forces must be determined by the customer. If any of these forces cannot be restrained by customer proven techniques, a Plidco® Clamp+Ring must be used.
Anchored pipe: A joint in which the pipe ends would not move when subjected to the types of forces listed under Pipe Not Anchored. The Plidco® Weld+Ends® Anchored Pipe rating is the maximum pressure at which the pipeline can be operated. It assumes that the pipeline is suitably anchored by welding, by the use of an appropriately rated Plidco® Clamp+Ring or by other customer proven techniques.
