Types of Carbon Flanges

 
 
01
 

Sliding flanges (slip-on)

The tube penetrates the cube in the same as in the flange form without touching the place of the touch face to which it is connected through external and internal welding seams. Owing to the low accuracy of the tube duration and better place flexibility, it can be regarded as easier compared to the neck flange. Its mechanical conditions are usually fine for exhaustion and resistance but weaker than the neck flanges.

 
02
 

Blind flanges

Due to various operating pressures, it is designed to cover the ends of tube openings, valves, or tubing. In the terminals where the temperature is a vector or function element or cyclic movements, it is advisable to render the closures by blind flanges and coupling necks.

 
03
 

Threaded flanges

Welding characteristics do not bear for making fast and simple assembly. It is used for specific applications (for instance, in pipelines with atmospheric temperatures and elevated pressures). Using them in ducts where there's a large temperature difference is not feasible.

Surface Treatment of Carbon Flange

Protective coatings, grease, oil, mill scale and annealing skin are the most common contaminants found on carbon steel. Protective coatings are being used to prevent corrosion after manufacturing, during construction and until the moment of installation. Unfortunately, there is no standardization for the use of conservation methods.

Suppliers of auxiliary pieces such as elbows, flanges, fittings etc. sometimes use 'tough' conservations which can only be removed with environmentally harmful methods. If before installation prefab pipespools are treated by specialized metal surface treatment companies, there are reasonable good facilities and inspection possibilities. A problem arises when such conservations have to be removed from a complete installation in situ.

Hardness test of Carbon Flange

 

 

Carbon steel hardness rockwell(HR) test, when the sample is too small or the Brinell hardness (HB) is greater than 450, it is measured by rockwell hardness. The test method is to use a diamond cone with a apex angle of 120 degrees or a steel ball with a diameter of 1.5875mm/3.175mm/ 6.35mm/12.7mm, and press it into the surface of the material to be tested under a certain load, and obtain the material from the depth of the indentation. Hardness. The three most commonly used scales are A, B, C, ie HRA, HRB, HRC.
· HRA is a hardness obtained with a 60Kg load and a diamond cone indenter for higher hardness materials. For example: steel sheet, hard alloy.
· HRB is a hardness obtained by using a 100Kg load and a 1.5875mm hardened steel ball for a material with a lower hardness. For example: mild steel, non-ferrous metals, annealed steel, etc.
· HRC is a hardness obtained with a 150Kg load and a diamond cone indenter for higher hardness materials. For example: hardened steel, cast iron, etc.

FAQ

 

Q: What is surface treatment of carbon flange?

A: Protective coatings, grease, oil, mill scale and annealing skin are the most common contaminants found on carbon steel. Protective coatings are being used to prevent corrosion after manufacturing, during construction and until the moment of installation.

Q: What material is used for carbon flanges?

A: The carbon flanges have carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum and vanadium depending on the material grade. The carbon steel pipe flange price list varies according to the material grade as well.

Q: What is the hardness test for low carbon flange?

A: The Brinell hardness test method consists of indenting the test material with a 10 mm diameter hardened steel or carbide ball subjected to a load of 3000 kg. For softer materials the load can be reduced to 1500 kg or 500 kg to avoid excessive indentation.

Q: What is the ASME standard for carbon flange?

A: ASME SA 524 Carbon Steel Seamless Pipes are Low Carbon Steel Pipes with max 0.21 % carbon content with combination of 0.90 – 1.35 % manganese. These Pipes are also known as mild steel pipes and tubes. ASME SA 524 Pipes are low-cost Pipes easy to form and shape.

Q: What are the functions of carbon flange?

A: Forged flanges are less carbon-free compared to molten flanges. The reason is that they do not oxidize quickly. They are flat, the construction is lightweight, and the molten flange comes with superior mechanical properties. Improper methods of forging may often result in irregular and broad grains. It is required to harden the forging and cracking than the casting flange.

Q: How is the hardness of carbon flange?

A: With more carbon content, the carbon steel flanges achieve toughness and strength but are less tough and ductile to weld. Higher carbon content may decrease the flange's melting point and its total temperature tolerance.

Q: What are the unique characteristics of carbon flange?

A: Each type of flange has its own unique characteristics and is used in different applications. Slip-on flanges, for example, are easy to install and are commonly used in low-pressure systems. Weld neck flanges, on the other hand, have a tapered hub and are used in high-pressure and high-temperature systems.

Q: What are the grades of carbon flange?

A: The most commonly used grade of carbon steel for flanges is ASTM A105. This is a standard grade for moderate to high-temperature services. Other grades, such as ASTM A350, are also used for low-temperature services. Additionally, high-yield strength grades such as ASTM A694 F52 and ASTM A694 F60, are used for high-pressure systems.
