New 3D Printing Technology for Low Temperature Thick Wall Tee

On November 17, the Engineering Materials Research Institute received the new product identification certificate from China Petroleum and Petrochemical Equipment Industry Association. On the first additive manufacturing test and research platform of PetroChina, the Institute independently designed TE555 low temperature large-diameter thick wall tee for oil and gas pipeline engineering using arc 3D printing technology, which is a global initiative and generally reaches the international advanced level.

3D printing Tee

The low temperature thick wall tee that passed the identification this time has a diameter of 1219mm and a weight of 4970kg. The thickness of the main and branch pipes is 67mm and uniform. The shoulder fillet reinforcement thickness is 164mm. The 3D printing tee technology solves the problems that the traditional hot drawing process is easy to cause the difference in the structure and performance of different parts of the tee, and the risk of brittle instability cracking.

As an enterprise specializing in R&D, production and sales of pipeline engineering supporting products, Haihao Group attaches great importance to the improvement of its own technology. At present, Haihao Group has rich experience in the production of flanges, steel pipes, pipe fittings, elbows, tees and other pipeline supporting products, and the product quality has been unanimously recognized by the domestic and international markets. In the future, Haihao will continue to pay attention to new technology progress, update its production technology at any time, and apply more Haihao products to pipeline projects around the world.
