How To Choose A Stainless Steel Pipe?

Do you want to buy stainless steel pipe? If the answer is yes, you will need to focus on a few things to ensure that you buy a stainless steel pipe of high-quality. Look for a pipe which is made from corrosion-resistant materials. Check the quality of the material and also solutions which will pass through the fittings. Look for a stainless steel pipe which has been manufactured adhering to a strict quality control system at all stages of the development process.

Give precedence to a manufacturer who possesses certificates such as PED 97/23/EC for safety compliance and ISO 9001:2008 for quality management. The safety of a pipe can be determined through proper testing methods. Top companies have an in-house facility to conduct different tests on the products they manufacture regularly.

How Do Hastelloy C276 and Chemical Processing Relate?

Chemical processing is a process in which chemicals and compounds are transformed through chemical reactions. The chemical reaction and processing involve the use of equipment like pumps, heat exchangers, evaporators, valves, pressure vessels, fittings, and flanges. The solutions and chemicals used to initiate the reactions trigger extreme conditions, hence the need to use the Hastelloy C276 pipe.

The Hastelloy C-276 is a nickel alloy, and it is known for its amazing corrosion-resistant properties. The common solutions used during the chemical process like hydrochloric, sulfuric, nitric, acetic and phosphoric acids alongside hydrofluoric compounds are very prevalent. And that’s where the corrosion-resistant properties of Hastelloy C276 pipe come in. The best thing about it is that it doesn’t allow the creation of grain boundary precipitates within the weld heat-affected zones, which makes it ideal for the equipment used in chemical fabrication and processing.

What Are the Hastelloy C276 Properties?

The Hastelloy C276 has outstanding properties, and that tells why it’s the preferred choice in the chemical processing industry.

  • All plates, sheets, and pipes made of Hastelloy C 276 showcase strong resistance to acetic anhydride, cupric and ferric chlorides, brine solutions, seawater, and hot and contaminated mineral acids
  • This nickel-based alloy is super resistant to chlorine dioxide solutions, hypochlorite, and wet chlorine gas
  • The alloy is suitable for oxidizing atmospheres to temperatures of up to 1900 degrees Fahrenheit. Itis also effective in the prevention of detrimental effects of general corrosion, cracking, crevice, and pitting
  • Since it has amazing corrosion resistance properties, itis the preferred choice in reaction vessels, transfer piping, evaporators, and heat exchangers. The structural quality of the alloy to resist harsh chemical processing conditions alongside the strength of resisting high temperatures from general corrosion, pitting, crevice, and pitting, make it the ideal choice for use in the equipment used in chemical process industries
  • The alloy can easily be processed and welded using standard shop fabrication procedures.  Besides, the alloy can be cold and hot-formed easily besides being welded using the standard procedures
  • Also, the alloy works to protect machines when kept in annealed conditions since heat treatment won’t harden it
  • The alloy is superbly resistant to corrosion and other harsh conditions, which makes it a superior choice for chemical processing

Why is C276 Used in Chemical Processing?

Wondering why most chemical processing industries use Hastelloy C276? These are the main reasons these industries have chosen it as the main material for ensuring efficiency:

  • The material has strong, resistant qualities against non-oxidizing and oxidizing acids owing to the high content of chromium and molybdenum
  • Hastelloy C276 exhibits strong resistance properties against stress corrosion cracking and sulfide stress cracking, which occurs naturally from the sour oilfield atmosphere
  • These alloys are easy to form and welds super-fast
  • The alloy is very ductile and has strong, resistant properties to chloride solutions. It also resists stress corrosion cracking

You can order these pipes from a reliable supplier online who offers them at affordable prices.

All You Need to Know About Powder Coating for Stainless Steel

316 stainless steel tube is one of the grades that you might choose to buy. Selecting the right series or grade may be such a hard task. You have to consider several factors. One of the factors you will have to look at is whether the stainless steel you are buying is powder-coated. This article briefly explains this feature:

What is Powder Coating?

One of the cost-effective methods you can use to improve the corrosion resistance of 316 stainless steel tube is coating it. Other ways that can be used to prevent corrosion include the use of corrosion-resistant alloys, which can be so expensive.

Powder coating is a term that refers to the shielding layer, which offers an irrepressible covering to materials and metals which need to be protected from corrosion and its effects.  It is a dry coating method, this means that it is firm when applied to the base of the material. This kind of coating comes in different colors, chemical composition, and thicknesses.

Application of Powder Coating

The use of a powder coating spray gun is the most popular way of powder coating. It pushes the powder coating substance at the substrate that is undergoing powder coating. The process also gives an electrostatic charge to the particles. These electrically charged particles aids in the formation of a bond.

The material or metal that has been coated is then put in a curing oven. The curing oven provides the heat that is necessary for the powder to stick together and stick to the base substance without any need for an electrical charge.

Another way of applying the powder coating to a substance is by using a fluidized bed. This process includes the heating of the base metal and then submerging it in a container that has a powder coating substance. After that, the coated material is put in a post-curing stage.

Types of Powder Coating

There are so many varieties of powder-coating that can be used. However, only two categories of powder coating materials exist. These are thermoplastics and Thermosets. The two are discussed below.

Thermoplastics

This type of powder coating material can be put to use for more than one time. This feature makes them of great benefit to removing the coat and other post-curing alterations. These types of materials are also ductile. They, therefore, have a perfect ability to withstand any impact without fracturing. Examples of these materials include polyester, chloride, and nylon.

Thermosets

This is a type of powder coating material that results in cross-links between the molecular structure when they are treated. This type of content is more permanent than thermoplastics. They are less affected by temperature after they have been cured. This feature makes them perfect for high-temperature uses.  They are also cheap and affordable than other types of coating.

Types of Metal that Can Be Powder Coated

The powder coating process is ideal for nearly all types of metals. The reason for this is because they can carry an electrostatic charge to have the material necessary in powder coating stick to them. The temperatures that are used in the curing process are also ideal for most metals.
