Product Process

Hot rolled can destroy the casting structure of steel ingot, refine the grains of steel and eliminate the defects of microstructure so that the steel structure is dense and the mechanical properties are improved. This

improvement is mainly reflected in the rolling direction, so that the steel is no longer isotopic to a certain extent. Bubbles cracks and porosity formed during pouring can also be welded under high temperature

and pressure.

❤ Main Classification

Hot rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes

geological steel pipes and other steel pipes.

Application

    1.Most underground pipelines are used for transportation, underground water is extracted during Gai Lou, and boiler hot water is used for transportation.

    2.Machining, bearing sleeves, machining mechanical parts, etc.

    3. Electrical: gas transmission and water power generation fluid pipeline.

    4 .Anti-static tubes of wind power plants.

Stable delivery time

If products is stock , about 7-10days can delivery after received deposit.

If custom products ,  100tons about 20-25days , exceed 100tons within 300tons about 40-50days , exceed 300tons, within 60days .

Product packaging material selection, good protection products

The uncoated aluminum sheets are separated by paper to prevent static electricity from damaging the surface.

The innermost is wrapped in kraft paper, waterproof plastic paper is added on the outer, and the edge is protected by a carton corner.

The trays are fumigation trays or non-fumigation trays, one trays weight about 3-4 tons.
