Parker CPS, Non-Welded Piping Systems Receives ASME B31 Compliance

Complete Piping Solutions (CPS), Parker's non-welded piping systems business unit, is now ASME B31.1 and B31.3 code compliant. CPS locations globally, including our Houston, TX operation, can now bid and install complete power-plant and process-plant piping work.

In order to achieve both ASME B31.1 and B31.3 compliance, the CPS unit had to meet requirements for the design, material, fabrication, erection, test, inspection, operation, and maintenance of piping systems. These systems are typically found in electric power generating stations, industrial and institutional plants, geothermal heating systems, central and district heating/cooling systems, petroleum refineries, chemical pharmaceutical, textile, paper, semiconductor, and cryogenic plants.


The following products and processes received B31 compliance:

  • Phastite® for Pipe permanent piping connections

  • CPS cold bending process (up to 10 inches)

  • Parflange® F37 in carbon steel and stainless steel

  • Seal-Lok (ORFS) fittings/Parflanged tube ends in carbon steel and stainless steel

  • Triple-Lok 37° flare fittings in carbon steel and stainless steel

Our CPS business unit has extensive experience in other market segments, and can now take our code compliant non-welded solutions into the B31 market. We can begin to educate industry professionals about the many benefits of non-welded piping that CPS provides.


What is CPS and how can it help piping system applications in the B31 market?

CPS is our non-welded solution to the welded pipe market. Traditionally, B31.1 and B31.3 pertained to a welded pipe. Now that we’ve achieved compliance, we’re able to offer a more cost-effective alternative to welded piping that reduces the lifetime cost of pipe installations.

Welded piping presents installation challenges and hidden failure modes. A non-welded pipe can effectively be installed without the need for welders, and Parker will even do the installation including pipe bending, flushing, and on-site fabrication. We can spec and design the system with the customer as well, working with their engineers to ensure optimal system efficiency.

Additionally, MRO for non-welded piping is more predictable and efficient. If a leak develops, it’s usually attributed to something fairly benign like an eroded O-ring or a loose bolt. Welding, on the other hand, requires hot work permits and pre and post-cleaning for maintenance. Many customers put up with minor weld leaks because they don’t want to go through the hassle of fixing welded pipe spools, with non-welded piping it’s an easy fix.

More than a superior component supplier, Parker is positioned globally as a system partner for non-welded piping systems. Our CPS team allows customers to take advantage of the largest cold bending capabilities in the industry. If you have any questions, please email us at pipingsolutions@parker.com.
