Pipe Testing Equipment: Overview
Pipe testing is an integral part of quality assurance in the architecture, engineering and construction (AEC) sector. These systematic evaluations help in detecting potential issues within piping systems, ranging from leaks to structural weaknesses. There are a wide range of pipes, offering a wide range of applications from transporting oil and gas to conveying water and more. Pipe testing is one of the crucial aspects of industrial practices, as it ensures the integrity and safety of pipelines. It involves the use of various pipe testing equipment and methods, such as pressure testing, leak detection, and flow rate testing, to identify any defects or weaknesses in the pipeline.
As one of the leading pipe testing manufacturers in the USA, we understand this critical need. At TESTRON GROUP, best pipe testing equipment suppliers, we offer a comprehensive range of pipe testing equipment and test methods. With a global presence in Europe, Saudi Arabia, India, South Africa, UAE, and China, we’re committed to providing reliable and innovative pipe testing solutions wherever your project takes you.
Different Types of Pipe Testing Methods
Here’s a quick look at some common methods used to evaluate pipe health, highlighting the key parameters involved:
Hydrostatic Pressure test
This is a widely used test for pipes designed to carry fluids under pressure. The pipe is filled with water and pressurized to a level exceeding its normal operating pressure. This helps identify leaks, weak points, and potential bursts. The test pressure is typically 1.5 times the rated pressure of the pipe.
TT-HPS Hydrostatic Pressure Tester Standards:
ISO 1167, ASTM D 1598, ASTM D 1599
Technical specifications:
- Output: Up to 100, 160 bar or 200 bar
- Capacity: 1 to 20 stations (30 stations on request)
- Pressure resolution: 0.01 bar
- Timing range: 0 ~ 10000h
- Time resolution: 1s
- Timing mode: Counter-up, counter-down
Ring Stiffness Test
This test measures a pipe’s ability to resist deformation under external loads applied perpendicular to its axis. A pipe section is subjected to a three-point or four-point bending load, and the deflection is measured. The test determines the pipe’s stiffness, which is critical for underground installations or pipes exposed to external pressure from soil or surrounding materials.
Ring Stiffness Tester Standards:
ISO9967, ISO9969, ISO13968

Heat Deflection Test
This test evaluates a pipe’s resistance to deformation under elevated temperatures and sustained load. A specific load is applied to a pipe segment while it’s heated at a controlled rate. The temperature at which the pipe deflects a predetermined amount is recorded. This test is crucial for pipes used in hot water lines or applications exposed to high temperatures.

Notched Constant Ligament Stress test
This destructive test measures a pipe’s resistance to crack propagation. A notch is machined into a pipe sample, and it’s then subjected to a constant tensile stress. The time it takes for the crack to propagate through the sample is measured. This test helps assess the pipe’s toughness and susceptibility to crack growth under stress.
Test Standards:
ASTM 5397-99 and ASTM F2136-18 are standards that are used to evaluate the stress crack resistance of polyolefin geomembranes and HDPE resins or pipe respectively.

Optional Accessory: TT-NNI Notch nicking device
Falling Weight Impact Test
This test evaluates a pipe’s resistance to fracture under a sudden impact load. A weighted tup (hammer) is dropped onto a pipe sample from a predetermined height. The test determines the amount of energy absorbed by the pipe before fracture and identifies its impact toughness. This test is crucial for pipes used in applications where they might experience impacts, such as pipelines in earthquake-prone areas.
