常见问题
?Why are dismantling joints used in water treatment plants?
They provide controlled axial adjustment during installation and create clearance for removing valves, pumps, meters and other flanged equipment during maintenance. Restrained designs can also transmit approved axial forces through the tie rods.
?Is a dismantling joint the same as an expansion joint?
No. A dismantling joint is mainly used for installation adjustment, equipment removal and restrained connection. A product intended for continuous thermal or operational movement must be selected separately.
?Should the dismantling joint be installed upstream or downstream of a valve?
The location depends on valve construction, removal direction, flow, lifting access, pipe supports and the approved layout. A downstream position is common in some arrangements, but it is not a universal requirement.
?Can a dismantling joint support the weight of a valve or pipeline?
No. Valves, pumps, meters and adjacent piping require independent foundations, supports or lifting arrangements. The dismantling joint should not be used as a load-bearing support.
?Which seal material should be used for potable water?
The base elastomer name alone is not sufficient. The specific compound, operating conditions and potable-water documentation required by the target project must be confirmed.
?What information is required for a dismantling-joint quotation?
Provide the nominal size, face-to-face length, medium, temperature, pressure, flange standard, equipment drawing, body and seal materials, coating, supports, removal direction, documentation requirements and quantity.
