Technical and Victaulic® Fittings

About Rendifield Technical and Victaulic®

fittings

RENDIFIELD MINING AND INDUSTRIAL PIPING SOLUTIONS mechanical fittings can be fabricated by buttwelding Tak-stubs to any of the range of buttweld fittings shown in the buttwelding fittings section so that they may be used with Tech-clamps.

Victaulic® fittings: As with Tak fittings, Victaulic® fittings can be fabricated by buttwelding Victaulic stubs on any of the range of buttweld fittings.

What is a Victaulic® fitting?

A Victaulic® fitting, commonly referred to as a Victaulic® coupling or simply Victaulic®, is a type of mechanical pipe connection system that provides a fast, efficient, and reliable way to join pipes without the need for welding, threading, or flanges.

Victaulic® fittings are designed to accommodate a wide range of pipe materials, including steel, stainless steel, ductile iron, PVC, HDPE, and more. This type of connection is often used in commercial, industrial, and construction applications.

What are the key components of a Victaulic® fitting?
  1. Grooved Coupling: The heart of the Victaulic® system is the grooved coupling, which consists of two halves that fit around the pipe ends. These halves have grooves that correspond to each other when properly aligned.
  2. Gasket: A rubber gasket is placed between the grooved coupling halves. This gasket provides a seal that prevents leaks and ensures a watertight connection.
  3. Bolts and Nuts: Bolts and nuts are used to secure the coupling halves around the pipe ends. When tightened, they create a secure and strong connection.
  4. Housings: The coupling halves are housed in a metal casing, which protects the gasket and helps maintain alignment during installation.
How are victaulic fittings used or installed typically?
  1. Pipe Preparation: The pipe ends are cleaned and marked for proper alignment. Any burrs, debris, or irregularities are removed.
  2. Gasket Placement: A rubber gasket is positioned in the groove of one of the coupling halves.
  3. Coupling Installation: The two coupling halves are placed around the pipe ends, with the gasket in between. The grooves of the two halves should align perfectly.
  4. Bolting: Bolts and nuts are inserted through the holes in the coupling housings and tightened to secure the coupling halves around the pipe ends. The tightness of the bolts compresses the gasket, creating a tight and leak-free seal.
  5. Tightening Sequence: Bolts are tightened in a specific sequence to ensure even pressure distribution and prevent distortion of the coupling. This helps maintain a uniform seal.
  6. Joint Inspection: The completed Victaulic joint is visually inspected for proper alignment, tightness of bolts, and any signs of leakage.
The advantages of using Victaulic® fittings

Victaulic® fittings are commonly used in HVAC systems, fire protection systems, water supply networks, industrial piping, and more. Proper installation, adherence to manufacturer guidelines, and compliance with industry standards are important to ensure the reliability and integrity of Victaulic connections.

  • Speed: Victaulic® connections can be installed quickly, reducing labor time compared to traditional welding or threading methods.
  • Flexibility: The system can accommodate various pipe materials and sizes, making it versatile for different applications.
  • No Heat or Flame: Unlike welding, Victaulic® connections do not require heat or an open flame, which can be advantageous in certain environments.
  • Maintenance: Victaulic® fittings allow for easy disassembly and reassembly, making maintenance or pipe modifications simpler.
  • Vibration and Movement Absorption: The design of the coupling allows for a degree of movement, which can be beneficial in applications where pipes may experience thermal expansion, contraction, or vibration.
Victaulic® Shouldered Fittings Product Description

• Galvanized shouldered fittings for use with Victaulic couplings for shouldered pipe
• Sizes from 2 – 8″/50 – 200 mm
• Working pressures are dictated by the coupling used
• Not intended for use with grooved or plain end couplings

Technical & Victaulic® fittings physical properties

Victaulic® offers a broad line of fabricated fittings in segmentally welded steel and full flow design in sizes through 24″/600 mm in a variety of straight and reducing styles. Fittings are fabricated of ASTM A-53 carbon steel, or other materials by special order.

Technical & Victaulic® fittings applications

Mechanical piping joining systems are used in HVAC, plumbing, fire protection and mining, water and wastewater treatment, oilfield operations, power plants, military, marine systems, and other industrial applications. Mechanical piping systems offer an alternative to welding, threading, and flanging for joining two pipe ends.
