Kloeckner provides top-quality A36 steel pipe that’s perfect for low- and- medium pressure transport.
Used mainly in the process industries, A36 steel comes in three types and two grades — types S, E, and F and grades A and B. Kloeckner Metals offers coated and welded/galvanized A53 steel in pipe in grades A and B. We routinely stock both grades in standard lengths and can cut to any length in a variety of shapes.
The chemical composition of A53 steel depends on the type and grade. The major variation between grades lies in the allowable percentages of carbon and manganese. Types S and E can have about 0.30% more manganese in grade B than in grade A. They can also have 0.05% more carbon. Type F’s composition is similar to the B grades in types S and E.
In appearance, A53’s pipe end features a flat end, a threaded end, and a socket end. It can connect through socket connection, coupling connection, or end welding.
The relative advantage of A53 piping lies in its application. A53 is best suited for transporting oil, steam, air, or water in low- or- medium- pressure applications. Its relative disadvantage is integral to its chemical composition. A53 does not contain silicon, an alloy that boosts heat resistance. Consequently, A53 is not rated for high temperature transportation.
As an all-purpose pipe, A53 shows up in refineries, generator plants, steam conduction, compressor stations, and natural gas transmission facilities. Companies in process industries mainly use A53 steel pipe since it works well as a structural pipe. The gas and oil industry in particular relies on A53 line pipe to extract liquid from the ground.
A53 steel pipe can be used for both pressure and mechanical applications, particularly transporting air, steam, oil, or gas. This pipe also appears in boiler water transmission, underground water drilling, machining parts, wind turbines, and anti-static tubes. Under certain conditions, it can be welded, coiled, formed, bent, or flanged.
A53 grade steel can be seamless, welded, coated, uncoated, or galvanized. Seamless steel pipes undergo one or more of the following processes: basic-oxygen, open-hearth, or electric furnace. Though more expensive than welded steel, seamless steel can be lighter and thinner due to its higher strength and greater heat resistance.
Welded steel pipes have a seam where the two pieces of the original plate met around the bar during formation. The seam must be heat treated to 1000o F to remove any untempered martensite. A53 grades A and B type E have been Electric-resistance-welded. Grade A continuously welded steel has been furnace-butt-welded. Type F has been furnace-welded.
Coated A53 steel is covered in a thin layer of zinc to help prevent corrosion. Galvanized A53 steel can undergo either a seamless or welding formation process. Black and hot-dipped galvanized steel pipe corrodes less easily than other steels.
Kloeckner routinely stocks coated, uncoated, welded, and galvanized A53 steel pipe in standard dimensions.
A53 steel is suitable for welding applications, including bending, coiling, and flanging with one caveat — welded steel cannot be flanged.
Manufacturers use a micro-alloying heat treatment process to fashion A53 pipe. A53 steel may be cold finished, however. If it is cold expanded, the steel should not expand past 1 1/2% of the pipe diameter.

Seamless and electric-resistance-welded grade A steel must show a minimum tensile strength of 48,000 psi and yield strength of 30,000 psi. Grade B steel should show a minimum tensile strength of 60,000 psi and yield strength of 35,000 psi. Continuous-Welded steel needs to show a minimum tensile strength of 45,000 psi and yield strength of 25,000 psi.
The steel gets tested in two ways.
In hydrostatic testing, conducted on all sizes of seamless and electric-resistance-weld pipe, the tester maintains pressure for at least five seconds to ascertain the metal’s strength. Mechanical tests must show a 90 degree bend for normal A53 uses and a 180 degree bend for close coiling.
A53 steel pipe can be welded, seamless, zinc coated, uncoated, or black or hot-dip galvanized.
To make a welded pipe, we curl a steel plate around a cylinder then weld the edges shut. For a seamless pipe, we insert the mold into hot steel so it creates the same cylindrical shape without the seam.
Zinc-coated steel has 0.2 – 0.5 mil of zinc mechanically bonded to its surface. The zinc should not exceed 1.8oz per ft2. Galvanized steel has had zinc applied by heat treatment, making it stronger, more corrosion resistant, and much longer lasting than powder-coated steel.
ANSWER:
A pipe is a hollow cylinder that can transmit liquid or gas. It must meet nominal pipe size. A tube’s hollow section can be round, rectangular, squared, or oval and is measured by wall thickness and outside diameter.
ANSWER:
Grade B steel contains slightly more manganese and carbon than grade A, making it have a higher yield and tensile strength.
ANSWER:
In coated steel, manufacturers mechanically bond zinc to the outside of the steel pipe. The coating may not exceed 1 mil in thickness, and typically runs just 0.2 – 0.5 mil. These zinc coatings help protect the carbon steel from rust and corrosion. Manufacturers may use a powder coating or they may galvanize the steel with coating.
ANSWER:
Welded steel has a seam where the plate was curled around a cylinder and the edges welded together. Galvanized steel is steel that has had a coating applied by heat treatment to protect the metal from corrosion.
