•  Conventional flange design has not changed for over 100 years
--------------------------------------------------------------------------------------------------------------
•  Need for greater versatility - handling and bolting - for use where space is 
   restricted
--------------------------------------------------------------------------------------------------------------
•  The Techlok clamp connector has much quicker make-up and release times
--------------------------------------------------------------------------------------------------------------
•  Strength and integrity of a welded joint coupled with the versatility of a 
   mechanical joint
--------------------------------------------------------------------------------------------------------------
•  The Techlok Clamp Connector was developed as the high pressure,
    low weight, leak-free alternative to the ANSI flange

•  Reuseable metal to metal self energised sealring (look image below)

How our clamp connector worksThe heart of Techlok’s success is the energised seal. Techlok clamp connectors do not rely on the conventional flange’s gaskets and correctly tensioned bolting to maintain the integrity of the seal.
The four basic elements of the Techlok clamp connector are hubs, sealring, clamps and bolting. When bolting the assembly, the hubs are drawn together by the twin wedge action of the two clamp segments compressing on the seal ring to make the first-stage self-energising seal.
The applied bolting loads are transmitted to the clamps through almost 360º contact with the hubs. And as the bolts are transversely mounted they are almost completely isolated from the operating loads, resulting in a strong, reliable yet compact connection. In service the sealring becomes even more effective as internal pressure reinforces the metal-to-metal seal to the extent that its strength can normally exceed the burst pressure of the connected pipe.
