500tons 09cuptire-a steel tube pipe exported to Singapore

High toughness and low brittleness transition temperature: with the increase of the working pressure of the 09CUPTIRE-A steel tube pipe gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure 09CUPTIRE-A steel tube pipe pipeline safety, toughness and strength must be improved at the same time.

Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of 09CUPTIRE-A steel tube pipe capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the 09CUPTIRE-A steel tube pipe overall strength, competitiveness and anti risk ability of the company.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of 09CUPTIRE-A steel tube pipe welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.

With the increase of temperature, the yield limit of 09CUPTIRE-A steel tube pipe will decrease monotonically, but the tensile strength of 09CUPTIRE-A steel tube pipe will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of 09CUPTIRE-A steel tube pipe. Near the blue brittleness temperature, the 09CUPTIRE-A steel tube pipe strength increases and the plasticity decreases. The elongation and section shrinkage of 09CUPTIRE-A steel tube pipe increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
