Carbon 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 Carbon steel pipe deformation process can be summarized as three stages: extension, perforation and finishing. Hot rolled 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 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.
Hot Rolled Steel Pipes in different size, specifications, grades & thickness as per the client's requirements. The range offered by tubes is available as per the international & national standard and can be available from us at affordable prices.

In order to prevent consumers from buying low-quality security doors, Hefei Secco shares three tricks to quickly purchase high-grade metal metal detection gates:
A look: see if the metal detection door shows signs of fading, whether the exterior is beautiful, and whether the power is normal.
The second hearing: listen to the metal detection door is a chaotic alarm or a normal alarm, the normal alarm can be initially considered that it is in line with the requirements.
Three tests: The installed metal detector door is flexible, easy to use, and easy for the staff to learn.
Hefei Secco 3 teach you to buy security doors
With the vigorous development of the commercial era, the selection and installation of metal detection doors not only need to consider the use of functions, but also need to pay more attention to the appearance of doors, the convenience and service life of people entering and exiting, and so on. Metal detection doors (also known as: security doors) can be roughly divided into: rain-proof security doors, economical security doors, portable security doors, metal security doors, copper security doors and several categories.
