The challenge
Being an innovator, introducing new technology to the market can be challenging. Especially if both your company and product are new – in a conservative market.

The challenging phases of marketing
First you need to create attention for your product and your company. Then interest for your product. Furthermore you need to make your potential client start evaluating and testing your product, and hopefully start purchasing your product.

A portfolio of «world’s first» technologies
The case for this article is the company PIPEOTECH. The company is the first baby of OTECHOS Technology Group, an innovative Norwegian company who has invented several patented & «world’s first» technologies the last few years. For instance the totally new CR Engine (250 bhp, 68 kg only, oil free), the new CR Compressor (as one of very few, awarded the EU Horizon 2020 Research & Innovation funding, Jan. 2016), the new CR Pump and CR Regenerator (CR = Centric Reciprocal), and last but not least, the product that PIPEOTECH is now marketing, the DeltaV-Seal – The World’s First Type Approved Gasket.

The Evaluation & Test phases – tested to the extreme

The product this article is about is a new sealing product, a gasket. A gasket is a simple «layer» used to seal between piping flanges, used in factories and facilities that transport anything in pipes, anything from gas, oil, steam, beverages and other products. Such a product has been on the market for ages, but a gasket is still a factory’s weakest link. They simply start leaking after time – which can have the most terrible consequences for employees and the environment.

This was a challenge that OTECHOS wanted to do something about and they invented the DeltaV-Seal, a metal gasket with extraordinary features, all embedded in what seems to be a simple piece of metal.

GE Healthcare’s 6 months long corrosion test
It is very interesting to see how industry majors are taking on the task to test the product, DeltaV-Seal.

GE Healthcare, the world’s largest producer of X-ray and MR contrast media, has a factory on the south-west coast of Norway, at Lista, where the factory is located just by the open sea. The location close by the salt ocean is a significant corrosion challenge on all equipment, and especially the gaskets. Traditional gaskets, which often are made of at least three different materials, are often the cause of corrosion problems due to the galvanic reaction with the materials in the piping flanges.

GE Healthcare took on the task very seriously, and started in October 2015 a six months long test period. The task was to test PIPEOTECH’s metal gasket and whether it would corrode after being exposed to salt water for a long period of time. The test ended in April 2016 and the test pipe was pulled out of the test tank. There was no corrosion on the 316L material of the DeltaV-Seal gasket after 6 months, and neither on the 316L flanges as consequence. On the same test pipe, there was a small, rust-free valve installed as well. The valved had started to corrode.

The gasket however was as clean as it was when it was installed, no corrosion at all, so the test was a success.

Test on LNG at minus 138°C
Another test that has been done was Intergas from Risør, Norway. Intergas delivers gas facilities including tanks and filling equipment to fill up LNG trucks. The challenge is that when you connect to the truck, it usually starts leaking when the temperature goes down to -138°C. The metal in the flanges and the gaskets contract and it starts leaking.

Intergas wanted to test DeltaV-Seal to see how it could handle the challenge of handling quick changes in temperature. They also wanted to test what our salesman said, that the DeltaV-Seal could seal at low torque, so they used about 50 % of the Statoil recommended torque, 50 Nm. The gasket was tested for two hours with absolutely no leakage, even at such a low torque. Intergas was impressed and today they deliver DeltaV-Seal together with their deliveries.

Intergas tested DeltaV-Seal with only 50 % torque on the bolts and at temperature of -138°C.

Becoming the world’s first

When developing the DeltaV-Seal, the inventors asked themselves. Why are everything else type approved, but not any gaskets?

OTECHOS took on the challenge, invited DnV GL and got the criterias for testing – the gasket to be installed on a pipe with flange, exposed it to 10 million vibrations and simoultaneously exposed the gasket for half a million pressure pulses from within.

OTECHOS did the test with DnV GL present the summer of 2015, which was finished with success, making the DeltaV-Seal the World’s First Type Approved Gasket.
