Connexus: A Mechanical Interference Fit (MIF) technology to connect carbon steel pipe for pipelines

Fast Construction

Connexus is a pipe joining system improving construction speed by more than 10X compared to traditional welding.

Cost Effective

Connexus is a streamlined and repeatable process requiring less equipment and labor. It reduces the variable costs associated with welding and labor improving budget certainty and operator time-to-revenue.

Quality Connection

Connexus is a proven technology backed by sound engineering design and an in-house connection testing program to satisfy a wide array of project designs.

Connexus: Mechanical
Pipe-Joint System

MIF technology has been used for over 50 years to safely and successfully connect pipe-joints worldwide. MPS Global has proven to be a reliable technology company delivering MIF technology. Connexus is the only MIF technology able to join pipe up to 20” in diameter. Connexus is a safe, strong and cost-effective process improving construction speed by more than 10X compared to traditional welding. Always with our eye on the bottom line, MPS Global is committed to improving operator time-to-revenue without compromising safety, reliability or pipeline performance.

The swedging of one end of a pipe (referred to as the pin) and expanding of the other end (referred to as the bell) of the same pipe.

Specialized joining machinery, hydraulic force and proprietary epoxy is used to connect the pin and belled ends.

Our Process

Connexus is a high-performance mechanical interference connection replacing conventional welding for gas and liquids pipelines. MIF technology is universally accepted to improve construction speed and lower project costs. What sets MPS Global apart is our ability to connect pipe joints ranging from 2″ to 20″ in diameter, coated or uncoated.

The Connexus process is simple. It begins with end preparation of the pipe which can take place on location, at the pipe-mill, coating plant or any desired location. The pipe end preparation does not negatively affect the metallurgy of the pipe, nor does it add time to the project. Once pipe is delivered onsite and staged along the right-of-way, the pin and belled ends are joined using hydraulic force aided by a proprietary epoxy.  The pipeline is ready for hydrostatic testing once the specified epoxy cure time has been met for all connections.

On average, it takes less than a minute to assemble a single connection. No welding or weld seam inspection equipment, like x-ray equipment, is required for assembly. The MPS Global Connexus MIF technology can operate in most weather conditions or terrain.

Connexus Mechanical Interference

The interference, metal-to-metal fit, is achieved by inserting a carefully expanded belled end into a tapered pin end.

Connexus Epoxy Seal

The epoxy seal created when one pipe is inserted into the other creates a flexible, airtight and corrosive resistant wall at the connection point of the joint.

Connexus Process

The interference fit is responsible for the axial load carrying capacity of the joint, relying on contact stresses between the pin and bell for strength.
