Straub Mechanical Couplings

Solid Solutions for Joining and Repairing all Types of Pipe

Fast, safe, and easy to install, Straub Mechanical Couplings from Hamilton Kent provide a watertight seal for installation or repair of all types and sizes of pipe. No welding is required, which means significant installation time savings and no fire watch needed on the job site. Straub couplings have far fewer bolts than flanged connections, which further reduces installation time and headaches. No special tools or pipe end preparation is needed. Sealing and anchoring functions are independent in Straub couplings, reducing stress on the components and resulting in flexible connections that can compensate for misalignment and angular deflection.

Applications

Straub mechanical couplings provide an engineered solution that can be designed to meet exact pipe ODs or provided as a standard size offering to meet application requirements.

Versatile and easy to install, Straub mechanical couplings are used to repair and join pipes throughout many industries, such as:

• Wastewater conveyance
• Power plant water transmission
• Marine applications
• Commercial and residential piping systems
• Transportation (piping under bridges)
• Fire protection systems

Advantages

Straub pipe couplings will join virtually all plain plain-ended pipe, including pipe made from different materials. Straub couplings can accommodate pipe diameters up to 150” (3.82m) and larger. Advantages of joining pipe with Straub couplings include:

• No welding, saving time and labor on sight (no fire watch needed)
• Installs easily and quickly
• Perfect for confined spaces
• Suitable for all types of pipes –steel, stainless steel, ductile iron, concrete, HDPE, and PVC
• Straub coupling housings and components are made from 316 stainless steel and are corrosion resistant
• Performs under high liquid temperatures – up to 100°C (212° F) with standard EPDM gaskets
• Noise dampening
• Reusability

Straub Solutions

Straub offers solutions to common problems found when joining pipes, such as:

• Angular deflection – use Straub couplings to join pipes that have an angular deflection between pipe ends
• Axial movement – compensate for axial movement of pipes with Straub-Flex, Open-Flex, and Air-Flex couplings
• Misalignment – connect two misaligned pipes up to 1% of the pipe’s outside diameter
• Difference in pipe diameters – connect pipes that have different diameters
