Steel Pipe round welded 1420х10-20 mm st3sp is a metal pipe with a round cross-section, which is manufactured by arc or electric welding. Low-alloy or carbon steel is used as the main raw material. The pipes have great durability, strength, and resistance to mechanical loads. They are widely used in construction, utilities, and mechanical engineering. They are used to lay pipelines transporting gas, water, and other liquids. They are produced with different wall thicknesses and diameters, which allows you to choose the best solution for a specific task. Welded pipes can have an anti-corrosion coating to increase service life.

Type by purpose
Used for laying underground communications, arranging collectors and sewer wells; during the construction of various metal structures; for external finishing of building facades and various structures. Electric welded pipe is also used where pressure resistance is required from the pipeline. The use of galvanized steel pipes in construction when laying various communications significantly extends the service life of pipelines. It is widely used in water supply, heat supply, gas supply, construction, installation of outdoor advertising, and traffic signs.
