u2-Lok Twin Ferrule Fittings

DNV·GL certificated

About the successful certification of u2-Lok Twin Ferrule Fittings fittings by DNV · GL (Det Norske Veritas · Germanischer Lloyd), the Schwer Fittings GmbH was delighted. The very extensive type examination included the following tests: Combined pressure pulse and vibration test, repeated assembly, leak testing, vacuum testing, pull test and a burst resistance.

Own production:
The new u2 fittings are designed according to its own production facilities in Europe. The semi-finished products are mostly from EU countries. Both the quality and the current pressure tests are carried out exclusively in the company's headquarters in Denkingen.

The design largely allows vibrations and pressure pulses to be absorbed, without any fear of leackage. This design, technical manufacturing, and quality properties ensure twin ferrule fittings a wide range of applications in industry, laboratory, and ­measurement system areas.
The use of high quality stainless steel guarantees a long service free life, also in the chemical industry.
u2-Lok Twin Ferrule Fittings, from 316 stainless steel as standard, are supplied assembled and ready to use. Even under heavy vibration conditions couplings ­guarantee a safe operation at high pressure or ­vacuum.

 

This is achieved through 4 effective design details:

1. The back ferrule affords damping of tube circuit vibrations through a spring like action. Furthermore, it prevents a carry-over of tightening torque from the coupling nut to front ferrule.
2. The front ferrule circumferentially seals the surface between the tube and coupling. Due to the inner taper the front ferrule is pressed into the tube so that a pressure-tight impression is formed.
3. Silvering of the coupling nut thread prevents seizing of the stainless steel coupling. This allows multi-use of a coupling.
4. A deep pipe bore, and entry taper, guarantees accurate positioning and centring of the tube.

On request, parts can also be supplied from Hastelloy, Titanium and other highly alloyd materials. Material certification according DIN ISO 10204, ANSI etc., available on reques. Special tests and approvals possible, if required.
