FlexSteel Connections for Faster Installation

Durable by Design:

  • Corrosion Resistant

  • Easily Installed

  • Cost-saving

  • Improved Performance

One mile of welded steel pipe has 132 joints; one mile of 6-inch, 1,500-psi FlexSteel pipe has just five connections.

Available in carbon steel, stainless steel or corrosion-resistant alloys, our midline and end fittings are designed, manufactured, and tested to API 15S standards, ensuring reliability. We frequently collaborate with customers to design and manufacture custom fittings.

FlexSteel pipe connections are swaged, eliminating the need for on-site welding and reducing the amount of equipment and crew members required. Since connections are only needed between each reel or coil of pipe, the installation process with FlexSteel is significantly faster. Installations can be performed by a FlexSteel technician or a FlexSteel-certified contractor.

FlexSteel pipe and connections are manufactured at our 420,000-square foot facility in Baytown, Texas.

How it Works

FlexSteel’s Swaging Process

FlexSteel’s swaging units use specialized hydraulic compression technology to form the steel walls of an end fitting or midline connection permanently onto the pipe wall. The swaging process provides a uniform, tight compression seal between two lengths of pipe and/or connections with other components.

The swaging equipment includes the press, a hydraulic power unit (HPU), a control system, and tooling. Swaging operations are well-suited for use in the factory or field environments. Swaging is simple and quick and creates fittings that are not sensitive to ambient temperature or cleanliness.

Durable by Design

Weldneck Fitting

A weldneck fitting can be used to weld FlexSteel pipe to other standard components. Weldnecks are generally used when welded connections are preferred in lieu of bolted connections.

Features

  • Not sensitive to cleanliness or ambient air temperature

  • Weld to another weldneck fitting or other schedule 40 components

  • High-pressure SCH 80 end fittings available

Flanged Fitting

The flanged fitting is most often used to connect with other standard pipeline components, such as valves and other upstream/downstream connections.

Features

  • Swivel flange used for aligning bolts to other flanged components

  • Available in ASME B16.5 lapped or welded flange (raised face or RTJ)

  • Available in ANSI 300 to 1500 class

Midline Fitting

The most common of all of our connections, this fitting is used to connect two lengths of FlexSteel pipe together without having an intermediate flanged or welded joint.

Features

  • One-piece fitting with no welding or bolting flanges

  • Internal venting allows capture of any permeated gas

  • O-ring seals

  • Smooth tapered bore for pigging

  • Available for all pressure classes

  • Low-profile OD is ideal for rehabilitation, pipe repairs, and plowing

Specialty Fitting

From 90s to crosses, reducers, and tees, our highly skilled design engineers can create a fitting to meet unique challenges such as extreme terrain changes and connections to specialized equipment.

Features

  • Completely customizable based on your project needs and specs

  • Endless variations and combination options

  • Engineering design expertise

  • Manufactured in-house at FlexSteel’s Houston connections facility

  • Streamlined ordering and manufacturing process

  • No need for welding in the field
