Specification and Types of Carbon Steel Flanges

The manufacturing of carbon steel pipes happens by using various techniques that produce a pipe with various characteristics. The carbon content present in the carbon steel pipe can be up to 2.1 percent of the weight of the total alloys.

An increase in the carbon percentage in the alloy helps to increase the tensile strength and hardness of the metal. The black carbon steel jacketed pipe would lose its ductile properties, even with a rise in the percentage of carbon.

About Carbon Steel Flanges

The manufacturing of Carbon Steel Flange is from various carbon steel grades. Common standards include DIN (2533 and other subspecs), MSS SP-44, ASTM A105N, and ASTM A694. They accompany pressure ratings from class 150 to 2500 in imperial and PN10 to PN40 for metric.

Carbon steel is the kind of steel that contains a carbon content of up to 2.1% by weight. AISI defines carbon steel as:

Maximum Mn 1.65%, Si 0.06%

Specified minimum of Cu shall not exceed 0.04%.

No alloy element (minimum content) is required for Cr, Mo, Ni, Ti, Va, etc.

With the increase of carbon element content, the steel will become stronger and sturdier after heat treatment. On the contrary, it becomes less ductile, which may be useful for your application. A high amount of carbon will reduce weldability if it is created without heat treatment.

Carbon steel may include alloy steel if not used as stainless steel.

Specification and Types of Carbon Steel Flanges

Various specifications of carbon steel pipes

Carbon Steel Pipes are available in a wide range of sizes of about ½” NB to 48” NB. The manufacturing of carbon steel pipes happens in many standards, namely, ASTM A/ASME SA 333 Grade 1,6; API 5L – PSL 1 Gr. A, B, X42, X46, X52, X56, X60, X65, X70; ASTM A/ASME SA 53 Grade A, B; ASTM A/ASME SA 106 Grade A, B, C.

The design of carbon steel pipes ranges as per the level of thickness. The range starts from SCH 40, SCH 80, SCH 160, or so on. The CS pipes find their applications in the industries like General Engineering, Pressure Vessels, Sugar, Steel, Boiler Equipment, Petrochemicals, Oil Refineries, and Power Generation (Thermal/Nuclear). Production of most carbon steel pipes is from Grade B steel for years and has a minimum yield strength of 35,000 psi.

Different types of Carbon Steel Pipes

Carbon Steel pipes are manufactured in various types like:

  Carbon Steel ERW Pipes

They have various features like intricate detailing, precision-engineered, appropriately structured, corrosion resistance, lightweight, economical and more. The ERW pipes are used in General & Heavy Engineering, Transmission Towers, Coal & Mining, Oil & Petro Chemicals, Boilers & Pressure Vessels, Automobile, and Ship Building.

  Carbon Steel Welded Pipes

The pipes are helpful during high-pressure conditions. In a wide range of industries like transport of waste and water, carbon steel pipes, chemical manufacturing, high-pressure applications, and oil & gas industries commonly use carbon steel pipes.

  Carbon Steel Fabricated Pipes

They offer tensile strength with corrosion resistance and high durability. The carbon steel fabricated pipes are useful in various industries. The industries include the following: desalination industry, ships industry, food industry, pulp and paper industry, energy industry, metallurgical industry, oil & gas industry, and chemical industry.

  Carbon Steel ASTM A335 Pipes

The ASTM A335 Seamless pipe consists of carbon steel with a minimum tensile strength of 415 MPa and minimum yield strength of 205 MPa. The material has high resistance and high durability to wear and tear. The manufacturing is of molybdenum, chromium, silicon, sulfur, phosphorus, manganese, and carbon. The composition of the ASME SA335 Grade Chrome Pipe helps give the characteristics of pipes. It includes corrosion resistance, hot hardness, wear resistance, stiffness, and strength.

  Carbon Steel Seamless Pipes

It contains more iron and carbon in its composition. The quality of the pipes depends on the materials present in them. It has copper, manganese, and trace amounts of silicon. Therefore, the Carbon Steel Seamless Pipe material is sturdier and resistant to stress. In heavy-duty facilities, the features make the pipes applicable.

  Carbon Steel LSAW Pipes

It has some fine features such as easy installation, rustproof and seamless finish. These LSAW pipes are expensive and not widely popular in lower value non-energy applications like water pipelines.
