Put Your Trust In Chemipetro Duplex And Flanges

January 15th, 2012

Chemipetro Limited is now the leader in the market when it comes to delivering duplex steel and flanges. We have achieved this through our unyielding commitment to quality across the board and a large part of this is due to us offering a 24 hour emergency breakdown service as standard.

Duplex stainless steels are so called because they have a microstructure made up of both austenite and ferrite in ratios between 40/60 and 50/50. This process gives the steel around twice the strength than other austenitic steel while also offering greater resistance to corrosive forces and the elements. The applications for this steel are numerous and widespread since it not only gives resistance to weather conditions and excessive temperatures but also stress cracking, corrosion and erosion as well as sulfide stress corrosion resistance.

This makes duplex steel the perfect high strength alternative to other austenitic steels. On top of this, the low thermal expansion and high heat conductivity also means that it has applications through welding and working. It means that here is a metal that is to a good degree malleable, but it is also strong and a cost-effective solution to your needs. This steel finds its uses in tubing and piping gas and oil as well as heat exchangers. It can carry various chemicals and chloride solutions through pressure vessels, tanks and pipes.

We also supply the highest quality flanges which can be fitted to various types of tubing to allow other connecting pipes.

The Amazing Qualities of Super Duplex

September 20th, 2011

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.

Chemipetro
We here at Chemipetro are one of the largest stockholders and manufacturers of super duplex pipes, fittings, fasteners and associated products in the United Kingdom. To view our extensive range of high-quality products in more detail, take some time to browse through the relevant pages here on our easy-to-use website.

Reap the Benefits of Duplex Pipe Fittings

June 21st, 2011

When you are selecting items to help you run your machinery, such as seamless steel tube and other such offerings, you no doubt want to get the most suitable offerings produced using the very best materials.

After all, there is no point in spending your hard-earned money on provisions that are in some way unsuitable.

Here at Chemipetro, we provide a vast array of products in a range of materials, including duplex stainless steel. Whether you are looking for pipes, weld fittings, fasteners or anything else, we might well have the perfect solution for you.

There are many advantages associated with items fashioned from this substance. For example, duplex grade stainless steel is around twice as strong as regular austenitic or ferritic steel. Meanwhile, because it contains less nickel and molybdenum than austenitic offerings it can often be cheaper.

Also, due to its added strength, less of the material has to be used, meaning structures can be thinner and lighter.

Of course, when it comes to seamless steel tube and other such offerings, you can choose from other materials too. By taking a look around our website and finding out a little more about the respective properties of the metals, you might be able to come to a decision concerning what you are seeking.

Also, you can always get in touch with our friendly and expert team by phone if you have any questions about the products we offer. This means you shouldn’t struggle to make the ideal selection for your company.

Why Choose Duplex or Super Duplex?

June 3rd, 2011

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.

Super Duplex Sets the Standards

May 6th, 2011

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.

What is Duplex Stainless Steel?

February 21st, 2011

There are very few people who have not heard of stainless steel. After all, many common items in homes, gardens and workplaces around the world are made from this material. Its properties have made it popular among manufactures and consumers alike.

Indeed, here at Chemipetro we use the substance in many of our products, such as flanges and pipe fittings.

However, unlike its more well known sibling, duplex stainless steel remains somewhat mysterious for many people.

This metal gets its name because it has a two-phase microstructure that consists of grains of ferritic and austenitic stainless steel.

It has a number of properties that make it attractive to manufacturers of flanges, pipe fittings and other such things. For example, it is around twice as strong as regular versions of the metal and it is also significantly tougher and more ductile.

As with other types of stainless steel, its corrosion resistance depends mainly on its specific composition.

Meanwhile, the duplex versions are very good at resisting corrosion cracking.

In terms of cost, it can be cheaper because of its lower alloying content and this is particularly the case during times of high alloy surcharges. Also, because of its enhanced strength, it is often possible to reduce the section thickness, meaning less of it needs to be used.

For this reason, both cost and weight savings can sometimes be achieved compared with other forms of stainless steel.

So, if you have not yet begun using products made from this metal, now may be a good time to start. To find out more about the products we offer, have a look at the relevant section of our website.
