Aço Preto: O Que é E Quais Suas Aplicações?

Apr 28, 2022

It is now a fairly versatile material, with diverse applicability in the industrial segment in the steel industry. Annually, thousands of tons of raw steel pipes are manufactured. The first production methods began in the 19th century and evolved over the course of two years, in order to meet modern projects that require resistance and safety.


The application and function of the structure depends on the standard in which these tubes are fitted. This type of tube can be sewn or not, being useful for assembling structures on quadras, scaffolding, transportation of non-corrosive and combustible fluids, electrical installations, among other functions.


This material is generally developed for use with natural gas and propane and, therefore, must be in compliance with standards to ensure a pressure rating of approximately 150 psi (Pounds per Square Inch, in Portuguese: pounds per square inch).


It now has multiple utilities in the most diverse segments and can meet the demand of each sector according to its variation. Do you know what the main advantages and applications of this year are? We separate all product information to throw away your doubts, confirm!


Or what's up?



The dark color of the heat is caused by ferrous oxide that arises during the manufacturing of the tube, when it has not been coated with a substrate such as zinc or ink. Generally, this tube is joined by welding or mechanical couplings. It may or may not be galvanized, and can be applied in the most diverse situations.


Available in various formats and sizes, it is qualified within the market quality and safety standards, such as NBR 5590, NBR 5580, DIN 2440 and others.


It is a "light year" of gray bass. This means that the brown steel tube offers high corrosion resistance when compared to traditional cast iron tubing. It is also highly resistant to heat.


What are the applications of the red tube?



Very much so as to apply the material. The short carbon steel tube can transport gas and water for rural and urban areas, for pipes that protect the electrical fiace and that supply steam and high-pressure air. It is also used in the oil industry to channel large quantities of oil into locations that are difficult to access.


In function of its high resistance to heat, it is also used by companies and residences for the supply of natural gas or propane and fire sprinklers. It is now widely used in gas distribution inside and outside houses, water wells and exhaust systems. The structure is a common ferrous tube, widely used to connect appliances to supply lines.


What is the difference between black pipe and galvanized steel pipe?



The application of the structure depends on the existence or non-zinc coating. The galvanized steel tube has black rust on its surface after being forged and coated with a zinc film. Thus, it offers greater protection against corrosion and is mainly used in the conduction of compressed air, oil, water and other fluids.
