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

Ring Stiffness Tester Test parameters:

• Test parameters RST-52 RST-53

• Max. inner diameter 2000mm 3000mm
• Max. compression space (max. OD) 2100mm 3300mm
• Dimension (L x D x H) 650×1360×3300mm 650×1360×4300mm
• Power supply 220VAC 50Hz 2kVA

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.

HDT/VICAT Tester Standards:

ISO 75, ISO 306, ASTM D 1525, ASTM D 648

HDT/VICAT Tester Parameters:

• Number of stations 3/4/6

• Method C-8.0 Mpa
• Vicat
• VICAT mass 10N and 50N

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.

Technical Parameters:

• Test temperature – RT to 80°C
• Temperature accuracy – +0.5°C
• Number of test stations – 20 (may test 20 specimens)

• Max. load – 1.5 kg (load on specimen is up to 4.5 kg)
• Timing range – 0 to 9999h
• Timing accuracy – $10 s

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.

Falling Weight Impact Tester Standards:

ASTM D 2444, UL651-Schedule 40 and 80 rigid PVC conduit

Tensile Test

This fundamental test measures the mechanical properties of a pipe material, such as yield strength, ultimate tensile strength, and elongation.  A pipe sample with a specific gauge length is pulled until it breaks. The force applied and the change in length are recorded throughout the test, providing valuable data on the material’s strength and ductility.
