The Calendered Tubes with saw seam are very resistant, used for the conduction of liquids and gases.
Are structures used as support in civil construction and foundation support, especially in maritime works.
The Calendered Tubes are used in various sectors such as, for example, not: automotive, railway, naval, mining, paper and cellulose, sugar-alcohol, among others.
They are also present in large civil works, such as: stadiums, railway stations, shopping centers, airports, etc.
This type of tube has characteristics that greatly favor the industry, because it has a wide variety of materials in different thicknesses.
We can find round, square, rectangular and oblong tubes, with profiles: "U" simple, "U" stiffened, "l" electrowelded, "l" laminated, "U" laminated, cartola, flat laminated ferro, square laminated ferro, ferro "T" laminated.
Also attends to special designs with "Z" profile and others, depending on the client's order.
Manufacturing Process
Its manufacture is made by means of the calendering process, which does not use different metals such as carbon steel, stainless steel and aluminum.
In this manufacturing process of the Tube with saw seam, a flat format carbon steel sheet is transformed into a tube format, through calendering.
A machine that has a high capacity of torque and precision, twists or adjusts and gives origin to the curved format of the tube, favoring a better connection.
The end of the piece is done with longitudinal welding with a wide diameter, providing a complete seal, without faults, discontinuities, making the calendered steel tube with two of the best industrial equipment on the market.
Advantages two Calendered Tubes
The Calendered Tubes have various advantages, allow different applications and offer good solutions in robust liquid and gas conduction systems. I am very procured due to their benefits such as:
Resistance to aggressive environments;
flexibility;
Diversity in quantity of measures;
Accuracy;
Optimum results of productive performance;
Optimum cost/benefit.
In addition to all these advantages, the Seam Calendered Tubes are produced according to ASTM A-36/ A-283/ A-285, achieving greater durability, resistance and useful life for its component. .
These tubes also offer a good financial return for the company, due to their easy application, with fast installation, which avoids production stoppages and favors the entire system.
