Non-Welded Piping Systems

Non-Welded Piping is a proven alternative to conventional welded and threaded pipe connection methods, providing a safer, cleaner and more efficient way to install and maintain high-pressure piping systems.

Chase Resource is an Authorized Distributor and Installation Partner for Tube-Mac Piping Technologies Ltd. (TMI), providing non-welded and non-threaded piping products and project solutions across the ASEAN and Middle East markets.

With applications across hydraulic, lubrication, fire suppression, offshore, marine, industrial and other demanding environments, our solutions are designed to reduce installation time, eliminate hot work and provide reliable, leak-tight piping connections.

37° Flare Flange

A high-pressure non-welded flange connection designed primarily for hydraulic and lubrication systems.

The 37° Flare Flange system is suitable for thin- to medium-wall piping and provides a reliable connection without welding.

Ideal for Sch80 and below thickness tubes

Upto 8″ NPS (Available in Metric)

Mainly for Hydraulic and Lubrication Systems

Retain Ring Flange

The Retain Ring Flange system is designed for large-bore, high-pressure piping applications where thicker-wall pipe is required.

A machined groove, retain ring and flange assembly provide a secure mechanical connection without welding.

Ideal for Sch160 and above pipes
Upto 10″ NPS (Available in Metric)
Mainly for Hydraulic and Lubrication Systems

Pyplok®

Pyplok® is a mechanically attached, non-welded and non-threaded pipe joining system that uses 360° radial swaging to permanently connect the fitting to the pipe.

Pyplok® is particularly suited to applications where installation speed, safety, reliability and maintainability are critical.

Ideal for permanent installation and repair
Upto 4″ NPS / 115 mm / 2″ OD
For a wide variety of applications

PreFiS®

PreFiS® is a non-welded press fitting system that creates a permanent metal-to-metal sealed connection by axially pressing the fitting onto the pipe or tube.

Using a dedicated hydraulic press tool, the fitting can be installed in seconds without welding or threading.

Available from ½” to 3″ pipe and 10 mm to 88.9 mm tube
Metal-to-metal sealed connection
For a wide variety of applications

Why Choose Non-Welded Piping?

Faster Installation

Non-welded piping systems can significantly reduce installation time by eliminating many of the activities associated with conventional welded piping. Prefabricated piping can be prepared, cleaned and tested before reaching site, allowing installation teams to concentrate on assembly and commissioning.

No Hot Work

Non-welded connections eliminate the need for welding and associated hot-work activities. This can help reduce fire risks, minimize work permits and allow installation or maintenance work in areas where hot work may be difficult or undesirable.

Clean Installation

Welding can introduce contaminants such as slag, scale and other residues into a piping system. Non-welded systems avoid these welding-related contaminants and can simplify cleaning and flushing requirements, particularly in sensitive hydraulic applications.

Reliable, Leak-Tight Connections

Engineered mechanical connections and sealing systems provide reliable, leak-tight joints when installed according to the applicable manufacturer’s requirements. The absence of welded joints also eliminates a number of weld-related issues associated with fabrication, inspection and repair.

Reduced Project Cost

Non-welded piping can reduce overall project costs by minimizing welding requirements, shortening installation activities and simplifying maintenance and repair. The potential savings extend beyond initial installation and can include reduced downtime and easier future repairs.
