Manufacturing process of Stainless steel 45 Degree Socket Weld elbow:

1. Raw materials are returned to the factory for re-inspection
The raw materials required for the production of our company are purchased from large steel producers such as Shanghai Baosteel, Chengdu Iron and Steel Company, Beijing Shougang and Taiyuan Steel Plant according to the corresponding standards and user requirements. For alloy materials or stainless steel materials, such as domestic can not meet the quality requirements, Imported from the international market (Japan, USA, Germany, etc.). All incoming materials require a quality certificate for the accompanying materials.
2 After the materials enter the factory, the business department will report the purchased materials. The testing center will re-examine the appearance, geometric size, chemical composition and mechanical properties of the materials, and fill in the re-inspection records. The inspection materials that have passed the re-inspection shall be issued with inspection notices, and the qualified materials may be imported into the company's material warehouse. (Executing the company's quality management system procedure document "Incoming Inspection and Test Management Procedures")
3, cutting material + carbon steel material according to the size of the pipe fittings using oxygen - acetylene flame or sawing material, stainless steel material using a special sawing machine or plasma cutting. In the blanking process, it is required to carry out the necessary labeling and transplanting according to the specifications and materials of the materials, and the geometrical dimensions of the cut blanks are tested piece by piece.

4, heating forging + forging is an important process in the formation of pipe fittings, forging workers have many years of forging experience and skilled forging skills. The pipe is forged by the blank according to the forging process requirements of the corresponding material. The qualified blank is heated in the heating furnace and then forged. The blank of the large pipe is freely forged under the plywood hammer. All pipe blanks are required to meet the above requirements for Class II forgings.
5. Heat treatment of the billet + heat treatment of the forged billet for heat treatment according to different materials to achieve the comprehensive performance of eliminating stress, refining the structure, and improving the strength and toughness of the material. The heat treatment method of the stainless steel forging blank generally adopts the solid solution stabilization process; the heat treated forging blank is subjected to temperature monitoring during the heat treatment to prevent defects such as overheating and overburning, and the heat treatment report is filled out. After the heat treatment is completed, the metallographic analysis and hardness test are carried out according to the different requirements of the materials to verify the final effect of the heat treatment.

6, machining forming + according to different specifications, models and other requirements, according to the corresponding standard requirements using lathes, drilling machines and other machinery for machining the blank. Ensure that the product meets the standard requirements for the appearance and geometric dimensions. The inspection department inspects the product according to standard geometric dimensions and shape tolerance requirements.
7. Finished product inspection + Appearance inspection, geometric size, ultrasonic flaw detection and surface magnetic powder for all carbon steel forgings before storage, non-destructive testing of appearance inspection, geometric size, ultrasonic flaw detection, penetrant inspection, etc. of alloy steel forgings, and sampling with furnace Metallographic analysis ensures that the pass rate of the product is 100%. Fill in the inspection notice for the qualified products to be admitted to the warehouse management.
8. Marking, packaging and shipping + After testing to determine the product is qualified, the surface of the carbon steel forgings is coated with anti-dust oil to prevent the pipe fittings from rusting. The fittings is stamped according to user requirements.
