Wholesale China Duct Coupling Factory Quotes – Heavy Duty Flexible Coupling 1000Psi – DIKAI

Maximum Working Pressure • Accommodates pressures ranging from full vacuum (29.9 in Hg/760 mm Hg) up to 1000 psi/6894 kPa. • Working pressure dependent on material, wall thickness and size of pipe. Application • Joins standard roll grooved and cut grooved pipe, as well as grooved fittings, valves and accessories. • Provides a flexible pipe joint which allows for expansion, contraction and deflection. • Operating temperature dependent upon gasket and/or seal selection – see Section 3.0. • Exclusively for use with pipe and products which feature ends formed with the OGS groove profile (See section 7.0 for Reference Materials). Pipe Material • Carbon steel. • For use with stainless steel pipe, refer to publication 17.09 for pressure ratings and end loads.

General Notes: Maximum Working Pressure (CWP) listed is the maximum cold water pressure for general piping services tested to ASTM F1476 and or AWWA C606 methods. Figures listed are based on roll- or cut-grooved standard wall carbon steel pipe. For other pipe schedules or pipe materials, contact Shurjoint for additional information.  Max. End Load is calculated based on the maximum working pressure (CWP). Listed and or Approved Pressures are pressure ratings for fire protection systems, tested and approved by various approval bodies. Please always refer to the latest approval data posted on the Shurjoint website.  Field Joint Test: For one time only the system may be tested hydrostatically at 1½ times the maximum working pressure listed (AWWA C606 5.2.3). Warning: Piping systems must always be depressurized and drained before attempting disassembly and or removal of any components.  The 10 Year Limited Warranty applies to manufacturing defects only and does not cover severe service/temperature applications or wear parts. Shurjoint reserves the right to change specifications, designs and or standard without notice and without incurring any obligations.
