ASTM A182 Chrome Moly Blind Flange and Low Alloy Slip On Flanges supplier in Mumbai
What is Alloy Steel Flanges?
Alloy steel flanges are designed with a variety of alloys. The versatile flanges can be alloyed between 1% to 50%, helping in determining the various properties of these flanges. The content of alloys ensures that the flanges possess certain corrosion and oxidation resistance in the systems. Iron and carbon are the most common alloys in this grade. The robust high strength flanges showcase excellent mechanical performance across stress-induced setups.
Why Is Alloy Steel Flange Face Protection Important?
A face type in a flange is a gasket that is employed in sealing the flanged connection. Dents, damage, or corrosion build-up will lead to failure of the flange. This type of damage can lead to increase costs due to repairs or replacement ultimately resulting in delaying the project.
ASTM A182 F92 Weld Neck Flange vs SA182 F92 Slip On Flange
Flanges are classified based on their face type, load-bearing capacity, and functionality.
- ASTM A182 F92 weld neck flange is designed with a long protruding hub. Similarly, an SA182 F92 slip on flange is designed with a low-profile head.
- Slip on flanges are a feature in low pressure applications. Weld neck flanges are a common feature in high pressure setups.
- SOF flanges are slid on the pipe feature and welded, making use of one or more fillet welds. WNFR flanges are welded using a butt-weld.
Alloy Steel Lap Joint Flange Vs Alloy Steel Thread Flange
- Alloy steel lap joint flange is a two-part assembly consisting of a backing flange and a stub end. Alloy steel thread flange consists of threads that correspond to a valve or a pipe.
- A lap joint flange is butt-welded in place, while a threaded flange doesn’t need to be welded in place.
- Threaded alloy flanges are used in low-pressure setups. Lap joint alloy flanges are a choice in high-pressure systems.
Welding process of Large Diameter Alloy Steel Flange
Large diameter alloy steel flanges are welded in place using a singular weld joint. The flanges are divided into 8 equal parts and are shaped in an x shaped groove. The flange is readily welded in place, making use of manual arc welding process using CO2 gas shielded welding process.
