L14AM7 Long Weld Ferrule

The L14AM7 Long Weld Ferrule is a sanitary-grade stainless steel fitting designed for permanent, hygienic pipe connections. Manufactured from 304 stainless steel, this long weld ferrule is engineered for butt-weld installation and is 3A compliant for use in dairy, food, and beverage processing systems. The extended length provides consistent weld penetration and structural integrity across all pipe sizes.

Features & Advantages

  • 304 Stainless Steel Construction: Offers excellent corrosion resistance and durability for sanitary processing environments, with a maximum operating pressure of 250 psi at ambient temperature.

  • 3A Sanitary Standards Compliance: Meets 3-A Standard 63-03 (Authorization No. 621), making it suitable for applications where hygiene and cleanability are critical.

  • Long Weld Design: The extended barrel length (Dimension A consistent across sizes) provides ample surface area for orbital welding, ensuring strong, leak-resistant joints.

  • Versatile Sizing: Available from 1/2" to 6" Tube OD, supporting a wide range of sanitary piping systems with standardized dimensions.

Working Principle

The L14AM7 Long Weld Ferrule is installed by butt-welding the ferrule's barrel end directly to a sanitary tube or pipe. Once welded, the ferrule's clamp end (Tri-Clamp compatible) provides a flush, crevice-free sealing surface. When two ferrules are joined with a sanitary clamp and gasket, the ferrule acts as the compression sealing surface, creating a leak-proof connection that enables quick disassembly for cleaning without disturbing the welded joint.

FAQs

  • What does "L14AM7" signify in the model number?
    L14AM7 is Dixon's series designation for long weld ferrules in 304SS material. Variants with "-G" suffix denote 304SS, while "-R" suffix denotes 316L stainless steel.

  • What is the difference between long and standard weld ferrules?
    Long weld ferrules (like L14AM7) feature a longer barrel length compared to standard ferrules, which provides better heat dissipation during welding and prevents deformation of the sealing face.

  • Are these ferrules compatible with Tri-Clamp fittings?
    Yes, the clamp end is designed to standard Tri-Clamp dimensions, ensuring compatibility with most sanitary clamp systems used in the food, beverage, and pharmaceutical industries.

  • What applications are these ferrules suitable for?
    They are ideal for dairy, brewery, winery, food processing, and pharmaceutical applications where sanitary connections and 3A compliance are required
