Alloy Steel Conduction Pipes

The steel alloy drive tubes are tubes which serve to carry conveying fluids such as water, oil and steam. They can be used in conduction lines with cold rigid or flexible connections.

Its main advantages are: agility, ease and versatility in installation and maintenance, they can be painted, according to norms that regulate the application of colors in the identification of pipes for channeling fluids, gases or electrical conductors.

Alloy steel conduction tubes contain, in addition to the bonds between iron and carbon, other elements in significant proportions that can alter the chemical or mechanical properties of the material.

They are manufactured for specific situations, because with the addition and dosage of other metals it is possible to obtain steel tubes of greater hardness, ductility, tenacity, weldability or even steel tubes more resistant to extreme temperatures, pressure, corrosion, rupture and traction.

Applications of Alloy Steel Conduction Pipes

The steel alloy drive tubes are tubes widely used in power generation and petrochemical industries, its tensile strength limit and corrosion resistance. They are indicated for applications that present extremely high temperatures, for example in industrial devices, heat exchangers, boilers, among others.

They can also be used in metal structures, agricultural machinery and sectors of the shipbuilding, maintenance, civil construction and furniture industries.

It is worth noting that the product must be manufactured and installed in accordance with technical standards in force in the country, in order to provide the safety of the environment and the effectiveness of its use.
