Introduction to EN 10255 S195T Carbon Steel Tubes

by Stanley

Carbon steel tubes are extremely important in many fields because of their durability, cost-effectiveness, and adaptability. Carbon steel tubes meeting EN10255 S195T standard are a popular choice. These tubes, also known as mild steel tubes, are excellent candidates for welding and threading. This article provides a comprehensive analysis of EN 10255 S195T carbon steel tubes, including their properties, uses, and significance.

Understanding EN 10255 S195T Carbon Steel Tubes

European Standard (EN) 10255 S195T carbon steel tubes are non-alloy steel tubes that can be welded and threaded. The letters “S195T” on a steel’s grade label denote its particular chemical make-up and other characteristics. Common trade names for these tubes include “CS” (Carbon Steel) and “MS” (Mild Steel). They may not be as hard as high carbon steel tubes, but their surface hardness can be increased through carburizing.

Reasons to Use EN 10255 S195T Carbon Steel Tubes

Carbon steel tubes manufactured to EN 10255 standards can be used in a wide variety of contexts. The oil and gas industries, the transportation industry, the automotive industry, the water and electricity industries, the environmental protection industry, mechanical engineering, and infrastructure construction all make extensive use of these tubes. The tubes are highly recommended for use in demanding applications due to their resistance to a wide range of environmental and mechanical stresses.

Chemical Composition and Mechanical Properties

Chemical composition plays a role in the mechanical properties of EN 10255 S195T carbon steel tubes. Toughness comes from essential element carbon, while silicon boosts strength. When added to iron, manganese helps form a stable austenite structure, which increases the metal’s hardness, strength, and wear resistance. Although phosphorus weakens plasticity and toughness, it improves steel’s resistance to corrosion. But sulfur can affect how brittle steel becomes when heated.

Sizes and Measurements

S195T carbon steel tubes can be found in a wide variety of sizes as specified by EN 10255. Outside diameters and wall thicknesses of the tubes can be customized. These numbers are critical for deciding whether or not the tubes will work in a given situation. The standard includes a table that clearly contrasts various steel tubes in terms of their weight, diameter, and wall thickness. Having this comparison available is helpful when deciding which tube to use for a given task.

Inspection and Testing for Quality

Carbon steel tubes made to EN 10255’s S195T standard must be of the highest quality possible. Manufacturers use numerous tests, such as tensile tests, hydro tests, impact tests, and more, for quality control purposes. The strength, durability, and functionality of the tubes are tested under a variety of conditions. Dimensional inspections, leak tightness tests, and bend tests all help verify the tubes’ quality and durability.


Industries that require dependable, cost-effective, and flexible piping solutions will find EN 10255 S195T carbon steel tubes to be an excellent option. Their adaptability and usefulness stem from their composition, mechanical properties, and dimensional range. These tubes serve as the backbone of many different endeavors in the fields of infrastructure building, oil and gas transmission, and mechanical engineering. Because of the attention paid to quality control and testing by manufacturers, EN 10255 S195T carbon steel tubes are a reliable option for a wide variety of applications.
