Carbon Steel Flanges: Types, Specifications & Functions


Depending on the quality of carbon steel used, the flanges chemical composition can include manganese, phosphorus, carbon, Sulphur, copper, nickel, chromium, silicon, molybdenum, and vanadium. Flanges made from carbon steel can range in price from the low hundreds to the thousands. Western Steel Agency produces flanges of all styles and metal qualities.

Carbon steel comes in many different thicknesses and tensile strengths. The minimum tensile strength is 485 MPa, while the minimum yield strength is 250 MPa. Flanges according to ANSI B16.5 Class 150 standards are suitable for medium-pressure applications. Flanges come in an assortment of pressure classes and materials, all of which are dependent on the nominal bore sizes and wall thicknesses.

Carbon Steel Flange Types

1. Carbon Steel A350 LF2 Flange

Annealed, normalized, or forged carbon steel A350 LF2 flanges have moderate strength and provide leak-proof couplings at a cheap price. The increased hardness of these flanges makes them more desirable than standard austenitic stainless steel flanges.

2. Carbon Steel A182 Flanges

One of the most successful outcomes of chemistry experiments and bonding is found in Carbon Steel A182 Flanges. You won't need to replace these flanges anytime soon. They have a widespread application in fields as diverse as petroleum processing, chemical manufacturing, and paper making. Because of its sturdy construction and low likelihood of breaking down immediately after installation, this flange type is among the most trustworthy goods available today.

3. Carbon Steel A694 Flanges

Flanges made of carbon steel, type A694, are suitable for the high-pressure environments required by oil and gas pipelines. Since this steel grade can't be easily strengthened, manufacturers will need to build steel that can withstand cryogenic and high temperatures. Higher carbon content results in tougher and stronger steel after heat treatment.

4. Sliding Flanges

Carbon steel flanges form a tube that goes through the same-sized cube. When using external and internal welding seams, the connecting plane need not come into direct contact with the connecting face. We can consider it easier than the carbon steel flanges due to the lesser precision of the tube life and greater placement flexibility. The sliding flange's mechanical condition is often good for fatigue and strength, but so much weaker than the neck-straps.

5. Welding Neck Flanges

Flanges having a long, tapered neck and a connector at their base are known as welding neck flanges. Flange and pipe inner diameters are the same. It's helpful in high-stress professions where you need to be able to handle it.

6. Threaded Flanges

Despite their lack of welding properties, they provide fast and simple installation. Male NPT threaded pipes are very helpful in some circumstances (for example, in pipes subjected to high ambient temperatures and pressures).

7. Carbon Steel Fabricated Flanges

There is tensile strength, as well as resistance to corrosion and a long lifespan. Carbon steel manufactured pipes have numerous applications. Desalination, shipping, food production, paper making, power generation, metal working, oil and gas extraction, and chemical production are just some of the businesses represented.

8. Carbon Steel ASTM A335 Pipes

Carbon steel with a tensile strength of 415 MPa and yield strength of 205 MPa is what goes into making an ASTM A335 Seamless pipe. In terms of resistance to wear and tear, the material is exceptional. Chromium, Molybdenum, manganese, sulfur, phosphorus, silicon, and carbon are the raw materials.

This Pipe features those typical of pipes thanks to its chemical make-up. It has properties such as being wear resistance, resistant to corrosion, hot hardness stiffness, and strength.

9. Carbon Steel LSAW pipes

It's got some great qualities like being rustproof, having a seamless design, and being simple to set up. Although they are commonly used in high-value energy applications, LSAW pipes are rarely used in lower-value non-energy applications such as water pipelines due to their high cost. There's more iron and carbon in it.

The components used to construct the pipes are directly responsible for their quality. Copper, manganese, and even a little bit of silicon can be found in it. That's why carbon steel seamless pipe is so much more resilient and strong under pressure. Due to the design, the pipes can be used in high-traffic areas.

Carbon Steel Flange Material Specification

The outside diameters of carbon steel pipes range from half an inch to forty-eight inches. Many different specifications, including X52, X70, API 5L - B, X56, X46, PSL 1 Gr. A, X60, Grade 1,6, X65, ASTM A/ASME SA 53 Grade A, B, ASTM A/ASME SA 333 X42, and ASTM A/ASME SA 106 Grade A, B, C, are used in the production of carbon steel pipes.

Carbon steel pipes come in a variety of shapes and sizes, all of which are dependent on their wall thickness. SCH 80, SCH 40, SCH 160, etc. are just the beginning of the available options. General engineering, pressure vessels, sugar mills, steel mills, boiler plants, petrochemical plants, oil refineries, and nuclear power plants are just some of the many places you'll find CS pipes put to use. Pipes made of carbon steel are typically Grade B steel, which has a minimum yield strength of 35,000 psi, and has been used for decades.

A carbon steel has a carbon percentage of 2.1 or higher by weight. What is the AISI definition of

1. No requisite amount of alloying elements such as Cr, Mo, Ni, Ti, Va, etc.

2. The minimal amount of Cu required is 0.04%.

3. Composition: 1.65% Mn, 0.06% Si max.

Heat treatment improves the steel's hardness and strength, and the carbon content has a direct effect on these properties. The opposite was true; its ductility decreased. Whereas more carbon will decrease weldability if not heat treated.

Carbon Steel Flange Dimensions

Dimensions: ANSI/ASME B16.5, B 16.47 Series A & B, B16.48, BS4504, BS 10, EN-1092, DIN, etc.

Properties such as corrosion resistance, great durability, and smooth finishing are provided by this material. You can choose from a number of different variations. For instance, the pipe can be ended with Carbon Steel Blind Flanges. These flanges are made using premium materials. Carbon can be found in them at a percentage between 0.25% and 0.60%. Carbon and manganese give the material strength and ductility, making it ideal for use in manufacturing.

Most commonly alloyed with iron, modern carbon steel has a carbon concentration of up to 2.1% by weight. Steel without a lot of chromium or nickel can also be referred to as "carbon steel." A105's carbon content can range from 0.25 to 0.35 percent.

Steel can be made harder and stronger through heat treatment as its carbon content rises. Quenching, tempering, and normalizing are just a few of the many treatment processes commonly used in the industry.

Benefits of Using Carbon Steel Flanges

The reason for this is because of the high quality of its finishing, corrosion resistance, and durability. Several fields can benefit from it. Many different industries fall into this category, such as the energy sector, the chemical industry, the petrochemical industry, and others.
