Description
Clamp connectors are ideally used in High Pressure and High Temperature flowline systems and offer considerable advantages as opposed to conventional flanges. They save size, weight, allow 360° orientation and minimize rig-up installation and maintenance downtime. Pressure energized metal-to-metal sealing provides leak free connections with a lower bolt torque and no elastomeric seals.
The EISSEN Clamp Connectors are designed for Sour Gas service and severe environments.
All EISSEN Clamp Connectors are compliant with ASME VIII-div.2 – appendix 4, PED 2014/68/EU and NACE MR01-75 standard and are fully interchangeable with other well-known brands available on the market.
