Super duplex stainless steel was first developed for use in the sulphite paper industry in Sweden over 70 years ago. Today it is recognised as being an improvement on duplex stainless steel because its higher alloy content provides it with increased resistance levels to the potentially destructive effects of pitting, crevice and stress corrosion and cracking. In addition, it is also significantly stronger than normal stainless steel and duplex stainless steel.
Physical properties
Super duplex’s amazing physical properties allow it to resist corrosion fatigue, enjoy higher thermal conductivity and experience low coefficients of thermal expansion to a far greater degree than austentic stainless steels. Furthermore, tests have also shown that super duplex has high energy absorption, high strength, very effective resistance to sulphide stress corrosion and is ideal for welding. In addition, the high chromium levels present in super duplex stainless steel makes it far more resistant to acid chlorides and caustic solutions than other stainless steels. Naturally, this helps to make it the ideal solution for the most strenuous environments. In fact, these robust properties make it a very real replacement option for nickel based steels or 300 grade stainless alloys.

Pipes fail for all kinds of reasons. Simple weakness is the first and most obvious. If the pipe material just isn’t strong enough to take the weight of the soil above it and account for slow movement over time, it will break or crack. Super duplex pipes are good choices if there is any reason to fear this kind of failure.
Super duplex is a type of construction rather than a material. Pipes can be made from a variety of different things depending on the intended purpose. Most types of metal piping can rust or otherwise decay quite quickly, except for lead (very soft and also poisonous) and stainless steel. We stock seamless stainless steel pipe, which is one of the best types available.
Sometimes pipes fail not because they too weak or too old, but because of subsidence, invasion by large tree roots, freezing water, high gas pressure, or through some other kind of disturbance. If one corner of a pipe connection is moving and the other is fixed, there may be a great deal of strain on the pipe and it may eventually break. It’s not unknown for pipe failure to be a sign of something deeper going wrong at foundation level.
Failure can almost always be avoided by installing a high quality product like seamless stainless steel pipe, and making sure the conditions around the pipe are stable. If you are in any doubt about the best kind of pipe for a particular job, you can always get in touch. Our experts will be only too happy to help.

As a leading global supplier of super duplex and related alloy products, we keep our ear to the ground for industry news, particularly when it makes its way into the public arena. In July 2011 it was reported by news website wboy.com, that American Electric Power’s Mountaineer and Mitchell power plants (located in West Virginia, US) had both suffered internal corrosion due to a supposedly non-corrosive alloy corroding within the scrubbers (desulphurisation chambers) of the power plants.
According to an American Electric Power spokesperson the problem caused no serious damage and presented no likelihood of a catastrophic event. A task force was set up to investigate the issue and find a solution. Liners were finally added to the scrubbers and no further degradation has been reported. According to recent findings, a similar type of corrosion has been found within scrubbers produced by several other manufacturers.
Super duplex and related steel alloys are a speciality here at Chemipetro. Of course, our expert engineers are adept at creating small components like socket head cap screws etc, but a conundrum like terminal scrubber corrosion certainly peaks their interest!
We believe that shoddy standards and a “make-do” attitude could be behind scrubber performance issues. Our project management style is, of course, to keep costs down, but NEVER at the expense of safety and product performance.
If you’d like more information on any of our products – from couplings to socket head cap screws – get in touch today and together we’ll find a 100% reliable solution.

At Chemipetro, we have become one of the biggest suppliers of pipe fittings and seamless steel tube to the oil and gas industry around the world because we have built up a reputation for high quality products that will stand the test of time.
Testing is naturally an important part of making sure that components such as stud bolts, pipe flanges and seamless steel tubing are up to the wear and tear that will be put upon them.
We employ a highly-qualified team of quality testing engineers, researchers and mechanical operators who operate under a quality management system approved to BS EN ISO 9001 by Lloyds Register Quality Assurance.
For our customers who require special confidence that the products they are buying are particularly robust and safe, we also offer a number of special testing services.
These range from a Hydrogen Induced Cracking Inspection to check the effects of hydrogen on, for example, stud bolts, to a liquid penetrant inspection.
This costs relatively little money and can detect defects in seamless steel tubing that are not apparent to the naked eye. Our Magnet Particle Inspection can also detect surface flaws in stainless steel-type materials – we recommend duplex and super duplex stainless steels in many products because of their high strength and low corrosion levels.
Finally, Ultrasonic Inspection offers one of the most effective non-destructive methods of product testing, detecting even subtle internal damage. For further information, ask our advisers – they are waiting to help you.

If you are seeking a particularly strong grade of stainless steel, a recommended material is duplex grade stainless steel.
Duplex is around twice as strong as normal steel, known as ferritic or austenitic, and also has a resistance to corrosion that ranks alongside certain austenitic steels. However, it contains less molybdenum and nickel and is therefore cheaper.
Duplex, because of its light weight and reduced section thicknesses, finds many uses, particularly in the gas and oil industry. It is also popular with companies working in high chloride or marine environments, and is suitable – in a variety called lean duplex – for storing ethanol.
Around 70 years ago, scientists in Scandinavia developed super duplex stainless steels to be used in the sulphite paper business. Super duplex has an extremely high tensile strength, and can beat ordinary steels in corrosion resistance by a long chalk.
Super duplex’s low thermal expansion rates make it suitable for components that undergo heat changes, such as heat exchangers and cooling pipes.
At Chemipetro Ltd, duplex and super duplex are among the materials we use extensively – we are among largest stockholders and manufacturers of flanges, pipe, pipe fittings, fasteners and associated products in duplex, super duplex and high nickel alloys.
As experts in this field, we can advise on the correct products and materials for your project, and also provide everything you need to get the job done. Our website is packed with detailed information, and we pride ourselves on maintaining the most exemplary of standards.

As a leading worldwide industrial supplier of super duplex stainless steel, our researchers and engineering teams are more than encyclopaedic on the properties, functions and common uses of super duplex. But what are the benefits, in simple terms?
Qualities
Super duplex stainless steel embodies remarkable strength, resistance to crevice corrosion and pitting/stress cracking, workability, high thermal conductivity, high energy absorption, low thermal expansion, and resistance to sulphide stress corrosion in a single material. This makes it ideal for use in the production of mechanical and structural components.
Make-Up
The inherent make-up of the duplex family of stainless steels covers a range of qualities in terms of corrosion resistance that depends upon their alloy content. They are roughly twice as strong as austenitic or ferritic steels. Super duplex is formed from a mixed microstructure of almost equal fractions of austenite and ferrite, rather making it the best-in-class of the duplex family. Exemplary corrosion performance makes the duplex family – in particular super duplex – ideally suited to application in the marine industries.
Industrial Applications
Super duplex stainless steel pipes contending materials to the post financially thanks to its higher yield strength (savings are possible through reduced weight etc.) Super duplex is often the material of choice in the marine and fossil fuel industries. A few examples include heat exchangers in desalination plants, high strength resistant wiring, mining pipes for the transport of fossil fuels, and chemical oil tanks.
The duplex stainless steel family has seen success across the industrial board thanks to a potent combination of desirable qualities and cost effectiveness.

When purchasing seamless pipes, there are often different material choices. Here the materials available from Chemipetro, and what the benefits are of each individual type.
Some of the duplex stainless steel products from Chemipetro include tubing, seamless and welded pipes, fittings, flanges, pressure fittings and fasteners. Seamless and welded pipes in duplex stainless steel range from one half inch up to 60 inches. Some of the benefits of duplex are high strength, less expensive than austenitic stainless steel, low thermal expansion, and resistance to pitting, stress corrosion, cracking, and other issues.
Another choice for pipes are those made from super duplex stainless steel. Super duplex is a highly alloyed, high performance version of the duplex material. Chemipetro also offers pipes in this material from one inch up to 60 inches. The same benefits apply as those of the duplex, but this material is even stronger.
6% Moly, also known as 6MO, is another material used for pipes and other products like fittings, flanges, and fasteners. One of the major benefits of seamless pipes made from this material is that they are very highly resistant to stress corrosion and cracking from chloride. They are also fifty percent stronger than certain austenitic stainless steel pipes.
Titanium is also a good choice for materials. Titanium is very strong, and lightweight. Another benefit of this particular material is that it offers the opportunity for “cold bending,” where difficult or complex bends need to be made—with no need for fittings or flanges.
