Dismantling Joint
A flanged dismantling joint for setting installation length and creating removal clearance at an equipment interface. Select PN10, PN16 or PN25 and confirm the current drawing for the chosen size.
Product overview
The adjustable flanged assembly helps set installation length and create removal clearance for equipment installation and maintenance. Confirm the available adjustment and installation requirements from the selected current drawing.
Pressure options
PN10 and PN16 have separate dimension columns and flange drilling. PN25 has its own drawing and dimension table.
The adjustment is for installation and removal. Do not assume continuous movement in service or one adjustment distance across all sizes.

PN16 Dismantling Joint — size and flange selection
For a PN16 Dismantling Joint, select the required DN from the PN16 rows in the readable dimension table. Check the PN16 flange drilling, bolt dimensions and installation length against the matching drawing; do not substitute a PN10 or PN25 row. Use “Enquire about PN16” to send the pressure configuration with your request.
Catalogue dimensions
Source: AQUAFITTING English catalogue 2023, pages 6–7. Dimension symbols follow the corresponding source drawing. Confirm the selected configuration and current dimensions before ordering. PN10, PN16 and PN25 configurations are separate. Bolt length and L2 are transcribed separately as printed; confirm both on the selected current drawing. Use the pressure-specific document and enquiry route.

Product FAQs
How do the pressure configurations differ?
PN10 and PN16 use separate columns in the original dimension table. PN25 has its own technical drawing and dimension table. Confirm flange drilling and the current drawing for the selected size.
Can the joint accommodate continuous movement in service?
The adjustment is for installation and removal. Do not assume continuous movement in service or one adjustment distance across all sizes.
What should I include in an enquiry?
State the nominal size (DN), both flange interfaces and drilling, available installation space, service conditions, quantity and destination. Confirm the current drawing revision before quotation.
How do I select a Dismantling Joint PN16?
For a PN16 Dismantling Joint, select the required DN from the PN16 rows in the readable dimension table. Check the PN16 flange drilling, bolt dimensions and installation length against the matching drawing; do not substitute a PN10 or PN25 row. Use “Enquire about PN16” to send the pressure configuration with your request.
