การติดตั้งข้อต่อถอดได้ใกล้วาล์ว

There is no universal position. The location should be selected according to the maintenance direction, piping layout, lifting access, flow arrangement, pipe anchors and approved project drawings. The joint must provide usable removal clearance, while the valve and pipeline remain independently supported.

No. A dismantling joint mainly provides controlled axial installation adjustment. It should not be used to force significantly misaligned, angled or non-parallel flanges into position.

Suitable flange gaskets are normally required between the valve, dismantling joint and pipeline flanges. Their material must match the medium, temperature, pressure and flange face. Confirm whether they are included in the ordered supply scope.

No. Valves, pipes and the joint must be properly supported by foundations, supports, hangers or lifting equipment. The dismantling joint should not be used as a load-bearing component.

Flange bolts connect the valve, joint and pipe flanges. Gland bolts compress the sealing ring around the telescopic section. Tie rods restrain the assembly and transmit approved axial forces. They have different functions and must be adjusted according to the product drawing.Flange bolts connect the valve, joint and pipe flanges.

Shut down and isolate the pipeline, fully depressurize and drain it, support the valve and adjacent pipe independently, and then release and collapse the joint according to the approved installation instructions. Never adjust or dismantle the joint under pressure.
