We specialize in the production of steel pipe, including hot-rolled seamless steel pipe, ERW steel pipe, LSAW steel pipe, spiral welded pipe, stainless steel pipe, RHS / SHS, normalized CCS grade E bulk vessels steel. The company's annual sales volume is 75000 tons, more than doubling in the past five years, mainly used in machinery, pipeline, heating, oil drilling, chemical industry, agricultural irrigation, urban construction and other industries. So far, our pipeline service customers come from more than 40 countries.
Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of normalized CCS grade E bulk vessels steel circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and normalized CCS grade E bulk vessels steel management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.
Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter normalized CCS grade E bulk vessels steel steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
The final heat treatment of quenched and tempered alloy steel, normalized CCS grade E bulk vessels steel is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
