Recent independent testing has confirmed the exceptional strength and reliability of our stainless steel CrimpLink pipe fittings—delivering performance far beyond traditional pressure ratings.
Upgraded Pressure Rating: 16 Bar to 40 Bar
Manufacturers of our stainless steel fittings have increased the official operating pressure rating from 16 bar to 40 bar. To validate this upgrade, we supplied 28 mm and 54 mm stainless steel pipes with CrimpLink fittings to an accredited mechanical testing laboratory.
40-Bar Pressure Hold Test
Each sample was pressurized to 40 bar and held for 8 hours at ambient temperature.
All test samples passed with no signs of stress, leakage, or deformation.
Burst Pressure Testing
After the initial test, the same samples were taken to maximum pump capacity to determine real-world burst tolerance.
-
28 mm stainless samples: Reached 98 bar and held for one full hour without failure.
-
54 mm sample: Reached 97 bar before the stop-end fitting released, dropping pressure to zero.
These results confirm that our stainless steel CrimpLink system comfortably handles extreme pressures well above typical building and industrial requirements.
Significance for Mechanical Wet Services Engineers
For multi-story and high-rise applications, higher pressure tolerance means water can be lifted using single-stage pumping systems.
This reduces:
-
Equipment requirements
-
Installation complexity
-
Long-term maintenance costs
The strength of stainless steel CrimpLink fittings directly improves system efficiency, design flexibility, and overall project cost savings.
Why Stainless Steel Pipe and Crimp Fittings Perform Better
Although stainless steel is often seen as a premium option, its longevity, corrosion resistance, and minimal maintenance needs make it a highly cost-effective choice over the system’s lifetime.
Challenges with Traditional Materials
Older plumbing standards were built around galvanized steel and black mild steel. Over time, copper became popular for its flow characteristics, but rising theft, site losses, and replacement costs have made copper increasingly inefficient.
Plastic piping solved some problems but introduced new ones:
-
Thicker walls required to meet pressure ratings
-
Larger external diameters
-
Reduced internal bore due to bulky fittings
-
Significant pressure and flow losses in systems with multiple tees and connectors
All these issues directly affect design accuracy, pump sizing, and system efficiency.
How Stainless Steel Solves These Problems
Stainless steel thin-wall tubing paired with crimp-on fittings maintains:
-
High pressure ratings without extra wall thickness
-
Full internal bore flow due to the flared-end fitting design
-
Durable, leak-free joints created through hydraulic crimping
-
Consistent performance across all pipe sizes from 15 mm to 108 mm
This results in a faster installation process, reduced risk of leaks, and excellent long-term system reliability.
A Faster, Stronger, More Reliable Piping System
Our stainless steel CrimpLink system delivers a permanent, leak-free connection rated at 40 bar operating pressure, with proven tolerances approaching 100 bar. It is installer-friendly, time-saving, and cost-effective—making it ideal for commercial, industrial, and high-rise mechanical services.
