The company specializes in the research and development, production and sales of TM rolled GL-AH 32 higher strength steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has TM rolled GL-AH 32 higher strength steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,TM rolled GL-AH 32 higher strength steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
The company attaches great importance to logistics services, sets up our own transport truck fleet, improves customer response capacity through the improvement of logistics capacity, and further reduces costs. Customers ordering TM rolled GL-AH 32 higher strength steel steel from our company can not only enjoy the service of fast delivery, but also enjoy lower transportation costs. Fast, accurate, simple and efficient has always been our principle.
Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.
In December of 2015, our regular India customer sent us an inquiry for TM rolled GL-AH 32 higher strength steel pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.
Q550C steel belongs to low alloy high strength steel. Chemical composition of Q550C steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 0.80, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. Mechanical properties of Q550C steel: yield strength ≥ 550 MPa, tensile strength 600-780 MPa, elongation after fracture ≥ 16%, impact energy ≥ 55J. TM rolled GL-AH 32 higher strength steel, Q550C steel is mainly used for manufacturing various large-scale engineering structural components and construction machinery. Due to its high strength, Q550C steel can meet the requirements of large-scale and lightweight construction machinery.
Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
