Dismantling Joint

2 main types of dismantling joints, in type A (100% restrained) & type B (50% restrained).

Features (Type A):

• Counters the impact of expansion (up to 5 mm) 
• Ensures safety during movements of bridges, chambers and pump stations. 
• Offers a 3° angular deflection
• Allows linking of mis-aligned pipes and equipment
• Body / end ring:
  • Fabricated rolled steel grade S275JR according to EN 10025-1:2004.
  • Other grade or materials are also available upon request.
• Stud/ hexagon bolt, nuts and washers:
  • Hot dip galvanized to EN 1461:2009.
  • Optional: Stainless steel grade 304 and 316.
• Gasket / Sealing Ring:
  • Ethylene Propylene (EPDM) to MS672(1999) or EN 681-1:1996 (Table 2 – ‘WA’/’WC’).
• Standard Corrosion Protection:
  • FBE – Fusion bonded epoxy powder coating internally and externally at 250μ min. thickness (up to DN1600), cold applied epoxy coating (>DN1600)

Features (Type B):

• Dismantling Joint can compensate for differences in flange to flange distance.
• Type B dismantling joints require less number of tie bars and flange holes, allowing easy installation of pipelines. Moreover, the tie bars act as flange joining bolts themselves, allowing a further simplified and swift installation without compromising on security, resistance and pressure rating of the system.
• Body / clamping ring / end ring:
  • Fabricated rolled steel grade S275JR according to EN 10025-1:2004.
  • Other grade or materials are also available upon request.
• Stud/ hexagon bolt, nuts and washers:
  • Hot dip galvanized to EN ISO 1461:2009
  • Optional: Stainless steel grade 304 and 316
• Gasket / Sealing Ring:
  • Ethylene Propylene (EPDM) to MS672(1999) or EN 681-1:1996 (Table 2 – ‘WA’/’WC’)
• Standard Corrosion Protection:
  • FBE – Fusion bonded epoxy powder coating internally and externally at 250μ min. thickness (up to DN1600), cold applied epoxy coating (>DN1600)
