Yuantai Derun Steel Pipe Manufacturing Group – Square and Rectangular Pipe Project Case

The square tube of Yuantai Derun is widely used. It has participated in major engineering cases for many times. According to different use scenarios, its uses are as follows:
1. Square and rectangular steel pipes for structures, machinery manufacturing, steel construction and geological drilling, etc.
2. Hot rolled H-section steel is widely used in building steel structures (such as factory buildings), and can also be combined into a lightweight roof truss bearing system; It can also be used as the forming material of other metal or nonmetal materials.
3. Welded steel pipes can be used to transport fluids and powdery solids, exchange heat energy, and manufacture mechanical parts and engineering structures.
4. The cold-formed thin-walled square and rectangular tubes are widely used. It is mainly used as low alloy high strength material for automobile body.
5. The main pressure parts of tubes for medium and low pressure boilers are made of high-quality carbon steel Q235A through 10 atmospheric pressures.
6. One of the important parts of high pressure boiler is the drum. Its working temperature is about 450 ° C, which requires the steel plate to have high endurance strength, good oxidation resistance and certain organizational stability.
7. In addition to ensuring chemical composition and mechanical properties, seamless steel pipes for petroleum cracking shall undergo hydraulic test one by one, and shall undergo flaring and flattening tests.

Yuantai steel hollow section for steel structure using for many famous projets.Among the 1500 famous domestic and foreign engineering cases, including Hong Kong Zhuhai Macao Bridge, the National Grand Theater, Singapore Google Building, Cairo CBD, Egypt One Million Ferdinand Land Greenhouse Improvement Project, Dubai Villa High end Villa Project, Qatar Lucille World Cup Venue Project, etc
