Stainless Steel Pipes & Applications
There are several products like seamless pipes, welded pipes and flanges to choose from. So, it can be a difficult task to select which one suits your requirements and is also value for money. Each pipe has their own properties that gives itself unique use in respective industries. Hence, it becomes inevitable to understand their characteristics and how they can be applied to various industries.
Types of Stainless Steel Pipes
A seamless pipe is a pipe without a seam or a weld-joint. A solid round steel billet is heated at high temperatures to make the Seamless Steel pipes. These billets are pushed or pulled over a form to shape it into a hollow pipe which is then released through a die and mandrel combination to reduce the outside diameter and expand the inner diameter as per the requirements.
Due to its flexible nature, welded pipes can be used in virtually every industry. However, they perform better with respect to corrosion resistance than performing under withstanding pressure. These pipes are far more cost-effective because of the lightweight nature of the welded pipes and the materials used inside. These characteristics make welded pipes the best value for money.
Industries that use Stainless Steel Seamless Pipes
Oil and Gas – Technology is a key player in the oil and gas industry. Over the past couple of years, the need for corrosion-resistant piping has increased by a huge extent. For use at deeper levels, more pressure is placed at the duplex and super duplex stainless steel pipes. Under such harsh conditions, it is important to have sturdy pipes as the pipes can easily burst and become unusable for deeper depths if the pipes are not corrosion resistant.
Nuclear Power – It is not an easy task to obtain usable energy from atomic nuclei. The job of nuclear reactors is to heat water and produce steam which is then used to spin turbines that provide us energy. Due to the cooling requirements, most of these reactors are placed near the sea coast. In order to cool down these reactors, much of the water pumped in them is from the sea and it needs to be corrosive resistant to seawater. Stainless Steel Pipes can defend very well against corrosion from seawater and hence, they are more qualified and considered important in nuclear power industry.
LNG – LNG stands for Liquefied Natural gas. It is a gas which is temporarily converted to liquid form for easy transportation as its volume is greatly reduced for convenience and cheaper transportation. In some cases, transporting fuel via pipelines isn’t attainable and definitely not worth the cost, that is why it’s instead transported via a liquid type in refrigerant ocean vessels and road tankers. As such, it’s necessary to possess the correct piping that gives safe and economical LNG transport to deliver fossil fuel to components of the country or world that are difficult to reach.
Industries that use Stainless Steel Welded Pipes
Stainless steel is taken into account to be one amongst the foremost exceptional inventions within the history of humankind. Stainless-steel stands aside from the remainder of the metals because of its skillfulness in industries, in urban merchandise and in domestic use.
Stainless steel may be a reasonably metal alloy made of the mixture of steel and different metals like nickel and Cr. The composition of the metal alloy employed in stainless-steel determines the grades which may vary from low to high that refers to quality, durability, and conjointly temperature resistance.
Problems in Sugar Industry
#1 Coloring in Sugar: Approximately 20-25 kg of Fe2O3 is mixed with sugarcane juice for every 1000 tons processed through the sulphitation process which is a source of corrosion. It gives dark colour to sugarcane juice, resulting in loss of whiteness.
#2 24×7 producing: Continuous manufacturing offers less time for maintenance of equipment throughout the season. Corrosion happens throughout the off-season because of chemical reaction of low-carbon steel instrumentality. During the restarting process, most of this rust is transferred to Sugar that desires re-melting to scale back wastage.
#3 Hygiene: The tanks and equipment made-up from the low-carbon steel do not contribute to hygiene and also the resultant sugar fails to urge a decent worth in extremely competitive market.
Benefits of using Stainless Steel in Heat Exchanger and Chemical Industry:
- Resistance to heat
- Resistance to corrosion
