Product Description
Carbon steel piping is a durable material made from carbon steel, a steel alloy with iron and carbon. Because of its strength and ability to withstand stress, carbon steel pipe is used in a variety of heavy-duty industries like infrastructure, ships, distillers, and chemical fertilizer equipment.
The incredible strength of carbon steel means that carbon steel pipe can be made thinner and with less material while still being able to transport high volumes. This makes carbon steel piping a cost-effective material. Not only can less of it be used, but carbon steel is also recyclable, making it both environmentally-friendly and cost-effective.
Because it's easy to manufacture, carbon steel piping is a versatile material. We can make it in a variety of thicknesses and dimensions. It's also easy to cut and bent to fit wherever it's needed. Its also easily connected to joints, valves, and other pipe fittings.

Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow - liquids and gases (fluids), slurries, powders and masses of small solids.
Hot rolled seamless steel pipe deformation process can be summarized as three stages: extension, perforation and finishing. Hot rolled seamless steel pipes is relative to the cold-rolled, cold rolling is below the recrystallization temperature of the rolling and hot rolled is carried out at above the recrystallization temperature of the rolling. Hot rolled seamless steel pipe can damage the refinement of the crystal grains of the steel, cast microstructure of the steel ingot and eliminate the defects of the microstructure so that the the steel organization compacting, improves the mechanical properties. This improvement is reflected in the rolling direction so that the steel is no longer at a certain extent isotropic; pouring the formation of bubbles, cracks and osteoporosis, under high pressure and temperature can also be welded together.
