Hot-rolled coils (HRC) are a type of sheet product resembling a wound steel strip and are produced at hot-rolling mills. These products are widely used for construction, the machine industry, car manufacturing, the production of general-purpose, construction, oil and gas and special-purpose pipes, and as a work-piece for the further production of cold-rolled products.
Hot-rolled steel coils application
Hot-rolled coil is used to manufacture steel structures, pipes and closed sections, as well as to enclose structures and facade elements. Shaped and round pipes are mainly used in this industry for:
Support steel structures and frameworks of industrial and civil facilities
Protective enclosures for various utility lines (wires and cables, plastic or other channels)
Support of main pipelines, water lines and heat supply networks, bridges and trestles
Sewerage lines, flue ducts and ventilation systems
For road construction – poles, guides, drainage elements, lighting columns and crash barriers
Steel structures for use in sports grounds and children's playgrounds, to erect fences and partitions, and in other solutions
The key requirements of this segment to this kind of rolled product include minimum dimension tolerances, heavy coil weight, weldability, high strength and toughness, crack resistance (also at negative temperatures) and, for some specific spheres, exterior resistance. Recently, there has been a trend of cold-rolled steel products being replaced with less expensive, thin hot-rolled products in the construction segment. However, high-strength rolled product types are now widely being used to reduce the product weight.

Hot-rolled steel coils for manufacture of large diameter pipes
Large-diameter pipes from HRC steel are produced with spiral seams. Such technology allows to produce pipes with a diameter of up to 2,520 mm for the following segments:
Main pipelines for transportation of oil, gas and other substances
Process pipelines, heat supply networks, water lines and sewerage lines
Supports for industrial facilities, bridges and trestles, elements of onshore and offshore platforms
For these purposes, the hot-rolled steel sheet needs to be in coils weighing up to 32 tonnes, which makes it possible to increase equipment capacity and yield. The HRC should have such properties as good weldability, high strength and toughness, and crack resistance (also at negative temperatures). Given the increased aggressiveness of transported substances, demand is growing for rolled steel with guaranteed resistance to hydrogen sulphide media (HIC, SSC). Higher process pressure inside pipelines entails the need to use pipes with thicker walls and made of high-strength steel grades like X60-Х100.
