4. How to Protect Black Pipe ?
Black pipe is plain steel pipe without any protective coatings. Black pipe is used for a variety of applications around the home. It is very common to see black pipe used for your natural gas line and sprinkler system lines. Since black pipe has no protective coating, it may rust easily in wet or humid environments. To stop the pipe from rusting or corroding on the outside, you should provide a layer of protection on the outside of the pipe. The easiest method is painting it.
5.YuanTaiDeRun is a gold supplier and do trade assurance or not?
YES. We have strong cooperation with SINOSURE

12. what is alloy steel?
An iron-based mixture is considered to be an alloy steel when manganese is greater than 1.65%, silicon over 0.5%, copper above 0.6%, or other minimum quantities of alloying elements such as chromium, nickel, molybdenum, or tungsten are present. An enormous variety of distinct properties can be created for the steel by substituting these elements in the recipe.
13. what is Argon-Oxygen Decarburization?
A process for further refinement of stainless steel through reduction of carbon content
The amount of carbon in stainless steel must be lower than that in carbon steel or lower alloy steel (i.e., steel with alloying element content below 5%). While electric arc furnaces (EAF) are the conventional means of melting and refining stainless steel, AOD is an economical supplement, as operating time is shorter and temperatures are lower than in EAF steelmaking. In addition, using AOD for refining stainless steel increases the availability of the EAF for melting purposes.
Molten, unrefined steel is transferred from the EAF into a separate vessel. A mixture of argon and oxygen is blown from the bottom of the vessel through the melted steel. Cleaning agents are added to the vessel along with these gases to eliminate impurities, while the oxygen combines with carbon in the unrefined steel to reduce the carbon level. The presence of argon enhances the affinity of carbon for oxygen and thus facilitates the removal of carbon.
14. what is the corrosion of structural steel?
The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. In the absence of either, corrosion does not occur. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately 6 times the volume of the original material consumed in the process. The general corrosion process is illustrated here. As well as general corrosion, there are various types of localised corrosion that can also occur; bimetallic corrosion, pitting corrosion and crevice corrosion. However, these tend not to be significant for structural steelwork.The rate at which the corrosion process progresses depends on a number of factors relating to the ‘micro-climate’ immediately surrounding the structure, principally the time of wetness and the atmospheric pollution level. Because of variations in atmospheric environments, corrosion rate data cannot be generalised. However, environments can be broadly classified, and corresponding measured steel corrosion rates provide a useful indication of likely corrosion rates. More information can be found in BS EN ISO 12944-2 and BS EN ISO 9223

7. How steel is used in buildings and infrastructure?
The possibilities for using steel in buildings and infrastructure are limitless. The most common applications are listed below. For buildingsStructural sections: these provide a strong, stiff frame for the building and make up 25% of the steel use in buildings.Reinforcing bars: these add tensile strength and stiffness to concrete and make up 44% of steel use in buildings. Steel is used because it binds well to concrete, has a similar thermal expansion coefficient and is strong and relatively cost-effective. Reinforced concrete is also used to provide deep foundations and basements and is currently the world’s primary building material.Sheet products: 31% is in sheet products such as roofing, purlins, internal walls, ceilings, cladding, and insulating panels for exterior walls. Non-structural steel: steel is also found in many non-structural applications in buildings, such as heating and cooling equipment and interior ducting. Internal fixtures and fittings such as rails, shelving and stairs are also made of steel. For infrastructureTransport networks: steel is required for bridges, tunnels, rail track and in constructing buildings such as fueling stations, train stations, ports and airports. About 60% of steel use in this application is as rebar and the rest is sections, plates and rail track. Utilities (fuel, water, power): over 50% of the steel used for this application is in underground pipelines to distribute water to and from housing, and to distribute gas. The rest is mainly rebar for power stations and pumping houses.
