Manufacturing process and features of Anchor Flanges

Manufacturing Process:

  • Material Selection : Choose suitable materials such as carbon steel, stainless steel, or alloy steel based on the application requirements. The material must ensure the flange’s strength, durability, and resistance to environmental conditions.
  • Cutting : Raw materials are cut into specific shapes and sizes using methods like sawing, laser cutting, or water jet cutting. This forms the initial blank for the anchor flange.
  • Forging : The cut blanks are heated and forged under high pressure to shape the flange. Forging enhances the material’s grain structure, resulting in improved strength and structural integrity.
  • Machining : The forged blanks are machined to precise dimensions using CNC machines or other precision machining tools. This process includes creating the flange face, boring the central hole, and drilling bolt holes according to the required specifications.
  • Welding : Anchor flanges often require additional welding processes to attach the anchor or reinforcement components. High-quality welds ensure the structural integrity of the flange.
  • Heat Treatment : Depending on the material and application, the flanges may undergo heat treatment processes such as annealing, quenching, and tempering to enhance mechanical properties like toughness and hardness.
  • Surface Treatment : Apply surface treatments such as galvanizing, painting, or coating to improve corrosion resistance and aesthetic appeal.
  • Inspection and Quality Control : Flanges undergo rigorous quality control checks, including dimensional inspections, pressure testing, and material verification, to ensure they meet industry standards and specifications.
  • Marking and Packaging : Approved flanges are marked with essential information such as size, material grade, pressure rating, and standards. They are then packaged for storage and transportation.

Features of Anchor Flanges :

  • High Strength : Manufactured from robust materials and enhanced through forging and heat treatment, anchor flanges exhibit high strength to withstand significant forces.
  • Secure Anchorage : Designed to provide a stable anchor point in piping systems, preventing movement and ensuring system stability under pressure.
