PIPEOTECH AS provides a revolutionary, new sealing technology for pipe connections used in a variety of industries worldwide.

PIPEOTECH is a subsidiary of OTECHOS AS, located on the south coast of Norway. OTECHOS is a technology company, developing various highly advanced technologies to be launched in the near future.

OTECHOS is an offspring of the successful entrepreneurs who realized Quickflange, a company established in 2004, who in 2010 won the Norwegian NHO innovation prize for their revolutionary cold weld technology designed for pipe flanges.



Sealing leakage between flanges is a well-known problem in all industries using pipes and flanges. Studies show that sealings between flanges frequently appear to be the weakest part of a piping connection. Leakages may often cause loss of production and productivity, and as a result, significantly higher costs.




PIPEOTECH has developed a new metallic sealing technology, DeltaV-Seal™, the world’s first type approved and patented gasket.  – certified and type approved by DNV GL in 2015.


  • DNV GL type approved
  • ASME & DIN/EN standards
  • An all metal, one piece gasket. In equal material or a galvanic compatible material to the flange itself. Galvanic corrosion eliminated.
  • One universal gasket, applicable for a full variety of liquids and gases
  • Easy and cost effective storage and logistics
  • Leak proof – metal to metal multiple sealing. One primary, two secondary.
  • Seals damages to the pipe flanges (tested up to 0,3 mm)
  • Solid, metal to metal sealing. Less torque and no retightening of the bolts necessary
  • Fire safe, withstands as much heat as the flange connection itself. Blow out resistant
  • Leakage & burst / vibration & pressure tests approved by DNV GL in 2015
  • High mechanical stress and vibration resistant
  • No fragmentation, easy flange face cleaning
  • Long lifetime – low lifecycle cost
