Non-welded piping systems provide a reliable alternative to conventional welded pipe connections, eliminating the need for welding and associated hot-work procedures. Cenergy Offshore provides Tube-Mac non-welded piping solutions including, 37° Flare Flange, Retain Ring Flange and Pyplok® systems for hydraulic, lubrication and industrial piping applications.
37° Flare Flange
- Ideal for Sch80 and below thickness tubes
- Upto 8″ NPS (Available in Metric)
- Mainly for Hydraulic and Lubrication Systems
Retain Ring Flange
A non-welded piping connection using a grooved pipe end, retain ring and flange, with an O-ring seal retainer for reliable high-pressure applications using Sch 160 and thicker pipes.
- Ideal for Sch160 and above pipes
- Upto 10″ NPS (Available in Metric)
- Mainly for Hydraulic and Lubrication Systems
Pyplok®
A proprietary non-welded connection system that uses 360° radial swaging to permanently join pipe and tube, creating a reliable, leak-free cold connection without welding.
- Ideal for permanent installation and repair
- Upto 4″ NPS / 115 mm / 2″ OD
- For a wide variety of applications
Benefits
Faster Installation
Pipes are assembled simply by tightening joints, enabling much faster installation compared to welded piping.
No Hot Work
Enables safe, hazard-free pipe assembly without hot work, eliminating the need for safety permits and disruption of critical activities, while also avoiding welding-related risks such as radiation exposure.
Clean Installation
Is a clean and eco-friendly method, with no slag, fumes, or radiation, enabling faster flushing, cleaner joints, and reduced machinery wear due to contamination-free systems.
Leak Tight and Reliable
Ensures long-term reliability by eliminating weld-related contamination, erosion, stress corrosion, and fatigue failures, thereby protecting sensitive hydraulic equipment and extending machinery life.
Cost Effective
Delivers long-term cost savings by eliminating skilled welding labor, inspections, and cleaning processes, enabling easy installation, reliable sealed joints, and low-cost repairs throughout the system’s service life.
