This is a unique concept where the buyers connect the verified suppliers directly also get extensive information about piping products and alloys. Anyone can refer to this for their technical queries about oil and gas piping materials, as well as their properties and uses. This site attracts many of the engineers and project managers in whose list of favourites piping material.ae comes out in day-to-day queries; they refer it to their friends and colleagues also. This is innovative and the first time that this concept has been introduced to the middle east. The best part of this website that a user would find not only the trusted manufacturer or stockist of the steel pipe line products but also get exhaustive and trustworthy technical data sheets of the products along with tips for the buyer. Pipingmaterial.ae is a UAE based B2B portal and hundreds of thousands of users visit it daily from Saudi Arabia, Qatar, Oman, Dubai, and the other Mena countries.

At pipingmaterial.ae anybody can find any type of industrial steel products may be for agricultural, interior, home decor, medical and pharmaceutical industry like Corten steel, medical and surgical tubing

Here users can connect directly from genuine distributors and wholesalers and can get the lowest price within their region

pipingmaterial.ae is developed in the latest technology and require many piping engineers, content writers and software developers, digital marketers for continuous development and enhancement

Many suppliers and stockist join and post their company detail with original photos of their stocks and supplies from Abu Dhabi, India, muscat and Dubai. Each and every supplier verified by team of piping material before posting his business on website so that the buyers can connect only with the original manufacturers.

Even the student of mechanical engineering and metallurgy refer this for weight chart, standards, sizes, and welding methods.

Fasteners play the most important role in all construction oil and gas, automobile, and manufacturing industries. Most of them have employed one of the two types-the stainless steel fasteners, and the other is duplex fasteners that vary in characteristics to be made specific for use. Based on this, the pipingmaterial dot ae brings an intercomparison of SS fasteners with duplex fasteners, applications, material grades and standards followed by suppliers in UAE.

What are SS Fasteners?

Material Grades

Fasteners from stainless steel are generally known for excellent strength, corrosion resistance, and durability. The general grades of stainless steel for fasteners in commercial uses are-

Grade 304: Known as 18-8 stainless steel, it is made up of 18% chromium and 8% nickel. This alloy is used in an application that has a general-purpose requirement with an extreme level of requirement against corrosion.
Grade 316 :This grade contains molybdenum, which provides extra resistance to pitting and corrosion in harsh environments, thus it is used for marine applications.
Grade 410 : This is a martensitic stainless steel that provides excellent strength and moderate corrosion resistance, with applications such as where high strength is required coupled with low exposure of corrosive elements.

Applications of SS Fasteners

SS fasteners are versatile and most widely applied in the following:

Construction: They are excellent for structural applications as they cannot rust.
Food Processing: Their anti-hygienic property makes stainless steel suitable for food and drink processing industries.
Automotive: It has applications in many components of automobiles that exhibit strength and robustness.
Oil and Gas: Especially those in this field usually require a corrosion-resistant material considering extreme conditions.

In the UAE, most of the suppliers of SS fasteners have quality controls and meet some international standards. Even suppliers generally offer proper documentation certifying that their fasteners comply with the required standards, such as ASTM and ISO, amongst others.

Awareness on Duplex Fasteners

Material Composition: Duplex fasteners contain both austenitic and ferritic stainless steels. It normally contains about 22% chromium with approximately a nickel content of about 5%. Alloying provides duplex fasteners better resistance to stress cracking from corrosion than standard stainless steel fasteners.

Applications of Duplex Fasteners

Duplex fasteners have increasing application in considerably demanding applications. These include

Oil and Gas: Due to their extreme strength and since they are totally corrosion resistant, duplex fasteners can be applied in offshore platforms and refineries.
Chemical Processing: Since duplex fasteners can resist harsh chemicals, they are extensively utilized in chemical plants.
Marine Environment: Duplex fasteners can resist water corrosion. So, they are supplied in all marine applications.

The Duplex fasteners suppliers have products that are compliant with international standards and certifications. Qualities and performance of fasteners are tested before the products are released along with documentation, which satisfies all the industrial requirements of the industries that they serve.

Comparison between SS Fasteners vs. Duplex Fasteners

Resistance to Corrosion: Among the above said other important differences found between SS and duplex fasteners are resistances to corrosion. Duplex possesses good resistance to stress cracking by corrosion. General corrosion may be present in high-grade Stainless Steel fasteners such as 316. However, they cannot work in extreme conditions.
Strength: Duplex fasteners have more tensile strength than regular stainless-steel fasteners. Therefore, duplex fasteners are used in the heavy-duty application only. If a case comes with critical requirements of safety and durability, then that could determine the higher tensile strength.
Cost savings: Comparatively, generally duplex fasteners are more expensive compared to the SS fasteners. Duplex fasteners perform better in some applications but investment cost is highly very high. Most of the companies evaluate the benefits with the costs due to these standards that it reduces maintenance and replacement cost in the future.
Standards and Certifications: All the SS fasteners manufacturer in UAE and duplex fasteners manufacturer follow high standards like ASTM, ASME, and ISO. When they follow such high standards regarding the fasteners, it is sure that they would meet the given safety and performance requirement.

Conclusion

The choice between Stainless Steel fasteners and duplex steel bolts can thus be determined by application’s requirements, including environmental conditions, strength demanded, and budgetary conditions. Although SS fasteners are certainly versatile and cost-effective, duplex fasteners can perform more effectively under trying circumstances. This would help the manufacturers and engineers decide which kind of fastener to use in any given project. Having the procured products to be reliable, one should have sourced from reputed SS fasteners suppliers in UAE who meet the standards of the ASME, ASME. DIN, and JIS.
